Anatomy Lessons - Part Two By billy69boy My heart skipped a beat for several reasons, but I didn't spend any time contemplating them. I was more interested in my early morning guest floating around in my pool. I wondered how long she'd been there. "Hello, Kendra, and a good morning to you," I responded, trying not to sound too excited. "I hope you don't mind me being here so early. Actually, I came over as soon as mom left for work." She explained, answering my question before I asked. "No, no dear, as I said yesterday, you are welcome here anytime." "You left so abruptly yesterday, I felt kind of cheated...or maybe disappointed, I guess, not that I really care," she sniffed, as she stepped out of the pool and headed towards the picnic table. She sat opposite me, oblivious to her dripping hair and wet skin which she didn't bother to towel dry. The sun sparkled on her smooth body, and I felt a twinge in my crotch as I quickly recounted yesterday's anatomy lesson. "Hmmm, well I'm sorry I had to go out and leave you like that, but I was already running late for my appointment," I explained rather weakly. Deep down, I wondered what the hell I was thinking, leaving my willing student at such an inopportune time. I yearned to make it up to her. "Yes," she quickly responded, "it allowed me to hate you all over again." I was alarmed by her statement, but she immediately rebounded with a broad grin. "So, do you have to go anywhere today?" "As a matter of fact, I am free all day today, and I vow to make up for my bad manners yesterday," I promised. "Good, because you have a lot to teach me still, and we're already behind," she blurted out laughing, as she rose and slowly walked around to my side of the table, sitting next to me. My newspaper and the temperature of my coffee were already erased from my conscious mind. She had my full attention and I just concentrated on presenting myself as a calm, experienced and dedicated teacher. But, before I was able to ask her what she wanted to know next, I felt her hand on my leg, and it slowly approached in the direction of my, uh, 'junk'. I was speechless and I sat still, revealing nothing. Well, actually I revealed a lot more than I had planned. When her hand lightly rode over my stiff erection, her eyes lit up and she giggled in delight. "So, did you miss me then?" she asked. It was obvious she already knew the answer, even as I tried to act nonchalant and unaffected. "Perhaps," was all I would willingly admit. I reached out and cupped one of her breasts in my hand and she didn't flinch. Rather, she responded by fondling my hard cock over top of my shorts, making me squirm. The battle for sexual supremacy had begun. I reached behind her back and unclasped her tiny pink bikini top and it fell into her lap before she tossed it onto the table. She boldly slipped her hand under my shorts and squeezed my shaft tightly. She began to pump as I pawed at her breasts. "Sit up here on the table and tell me everything I need to know about oral sex," she commanded, to my surprise. As I stood up, she hooked her thumbs into my waistband and pulled my shorts down to my ankles, while I stepped out of them and sat down on top of the table, facing her. "That's what they mean by a 'Hummer', isn't it?" she asked, and I nodded my head as she continued to play with my private parts. In the process, she discovered my balls, and temporarily halted her interrogation as she explored the rest of my 'package'. "Oooh! What have we here?" she asked, as she grabbed a handful of my scrotum, causing me to jump a bit. "Do you like them to be played with too?" "Y-yes, but don't squeeze them too hard!" I cautioned. I don't know if she was listening, because all of a sudden she closed her eyes and she arched her back, presenting her boobs to me shamelessly. I squeezed them gently, as if to demonstrate my point. "Mmmm, yes, I see," she murmured, as her nipples hardened under my gentle but firm pinching. She exhaled deeply before going about her intimate inspection of my man parts. "So how do I start?" she asked without taking her eyes off her intended target. Now it was my turn to take a deep breath as she lifted my penis up for a look underneath. "See that line under there that goes from the head and on down an inch or two?" I asked, and she nodded her head. "Well, that's a very sensitive area, and if you lick...aaaah! Yes, like that..." I couldn't continue momentarily as she ran her warm velvety tongue from the base of my hard-on up to the tip of my bulging mushroom and then back down again. "Like that?" "Yes! Just like that! OOOOOOH! Very good! Are you sure you've never done this before?" I asked suspiciously. "No, never, but I tried to listen to what the girls at school had to say," she smiled shyly. "Okay, well, there are a lot of different ways to give...uh...Hummers, and I'll try to tell you what boys like the best," I offered, as my devious mind took over. "Oh good, that's what I want to learn!" she answered enthusiastically. "Well, first of all, it's really sexy if you only use your mouth, and you keep your hands off it, unlike giving a hand job, do you understand?" She nodded, wide-eyed. "In fact, since you mentioned BDSM, you can combine the two and make it even more exciting." "How so?" "The B and D part stands for Bondage and Discipline, which can mean a lot of different things, like tying someone up or spanking them, or some more extreme things that have to do with pain and pleasure," I explained vaguely. "Oh, well I kind of like the idea of being tied up, but I'm not interested in pain!" she declared. "Okay then, back to the Hummer: another way to make it exciting for your partner is if you let him tie your hands behind your back," I instructed, trying to speak as calmly and nonchalantly as I could muster. "It's a shame there's no rope around," she said as she made a quick survey of the back yard. "Hey! How about this?" She scooped up her bikini top and handed it to me, as she stood up, turned around and put her hands behind her back. I was flabbergasted, and I tried hard not to let her know how badly my hands were shaking as I bound her wrists firmly and then turned her around and helped her to sit down between my legs again. "Very well! Are you ready?" She nodded excitedly. "Oh, wait; there are a couple more things you should know: The boys will probably hold your head between their hands while you suck their cocks to kind of steady themselves. If they squeeze too tight, it's okay to ask them to loosen their grip a little, got it?" "And another thing: try to take as much of their shaft into your mouth, and the more the better! When you get more experience, you will eventually be able to take their whole length down your throat, but that takes some practice," I said as seriously as I could, and she contemplated this new image thoughtfully. "OH! That's called Deep Throating, right?" she blurted out. "Correct!" I assured her. "One last hint: when the boy starts to shake and his cock begins throbbing and spasming, concentrate on swallowing as much of his cum right down your throat...he'll love that!" She smiled broadly as the wheels in her brain processed all the new information I gave to her. By now my own cock was already screaming, and I didn't expect to last very long. "Let's try it!" she announced, as I pulled her head closer to my member which literally shivered in anticipation. "First, just run your soft tongue up and down the shaft, like you're licking a lollipop; yes dear, just like that...oh yes!" With each new lick, she looked up into my eyes, as if searching for my approval with every stroke of her tongue. I responded by tightening my grip on each side of her face and letting out a loud and revealing moan when her lips finally enveloped my erection and accepted it deep into her hot mouth. At that moment I experienced the true meaning of ecstasy. Not wanting to erupt too soon, I slowly guided her head back and forth, feeding more and more of my cock into her willing mouth. I looked down between my legs and watched as my young neighbor girl performed her very first blow job. I wanted it to be as memorable for her as it was for me, so I began to increase my rhythm bit by bit, until I was face fucking her in earnest. I pulled her head in tighter to my crotch and watched as my shaft nearly disappeared into her mouth altogether. She was such a trouper, going about her business diligently, and so I thought it would be a good idea to accelerate her education a bit by tightening my grip on her face and pushing the last few inches of my engorged shaft past her tonsils and down her throat. Her eyes opened wide in disbelief, and tears formed, but she held her ground. She stifled a few impulses to gag in the process, and so I pushed forward and felt her throat close around the head of my cock in exquisite guilty pleasure. I pushed and pulled her head as I buried my entire length down her throat, finally almost standing as I pumped her head full of the heaviest load of cum I had ever produced. Her eyes glazed over temporarily as she strove to gulp down every last drop, but alas, she choked in the end, and my cum burst out of her nose and at the sides of her mouth, as tears streamed down her cheeks. I finally released my grip on her head and slumped back onto the picnic table, totally spent and in need of oxygen. Amazingly, Kendra continued to suck and lick until my cock was clean and shiny. I looked down at her contented face, and she grinned proudly, her eyes now sparkly. "So, how was that?" she asked, knowing full well that she had exceeded all expectations. "I would say a lesson well learned!" I declared, as I grabbed a towel from the chair and gently cleaned up her glowing face. "If you untie my wrists, I can clean myself up," she suggested. "And I could use some tissues too, if you don't mind!" I happily obliged as I strutted over to the bar and brought back a box of tissues along with a couple of cold bottles of water and a bottle of suntan oil. As my favorite student wiped her face and nose and took a couple of hearty pulls from her water bottle, I busied myself by spreading another thick towel on top of the picnic table. "What's this?" she asked. "It looks like you've been in the sun too long, and I thought I'd oil you up so you don't burn," I explained. She jumped up without hesitation and took her place on the table, with her arms folded across her chest. I stood between the bench and the table and slowly applied the oil on her arms before placing them above her head. Her perky breasts stood up proudly, almost begging to be given the oil treatment too, which I was happily willing to oblige. She moaned playfully, her eyes closed, as I covered her chest and belly with oil. She squirmed a little in anticipation as I got closer to her bikini bottom, but then she changed her tone. When I bypassed that area and moved down to massage the oil into her legs, she snorted her disdain for me, but allowed me to continue without further comment. After I applied the oil to her feet and toes, she finally opened up her eyes and glared at me: "WELL?" Her eyes shot daggers at me. "Well what, sweetheart?" I answered with an innocent lilt to my voice. "You know damn right 'what', you awful tease! I'm hating you again, only MORE now!" "Oh, did I miss a spot?" I inquired, as I lightly ran my finger up her crotch. "OOOOH! You are such a jerk! I don't know why I ever thought to ask you ANYTHING!" I couldn't keep from chuckling. She was so cute when she didn't get her way... "Okay then, lift up so I can take this off," I said as I hooked my fingers in her waistband. I removed her bikini bottom and she plopped back down on the table. I leaned over top of her freshly shaved mound and inhaled her sweet girl scent. Without warning, I ran my tongue right up her smooth slit: "Oh Christ! OH MY GOD!!" Her hips jerked upward, and I almost bit my tongue...I held her down and licked again. And again. She squirmed and writhed under my mouth like a rodeo horse, and she used one of her new lessons and pulled my head down between her legs, and she didn't let go. I managed to get my hand in there, and two fingers easily slipped inside her aroused pussy. "That's it...that's better...oh yes, finger me...OH GOD!" I parted her labia with my fingers and exposed her clit to my tongue and I licked away. Immediately I felt her grabbing two fistfuls of my hair and pushing my face into her shuddering cunt while her head flopped back and forth on the table. I took her clit between my teeth and tickled it with the tip of my tongue, driving her berserk. "GEEEEEZ! OH LORD!" I spontaneously pushed her legs back until they rested on her chest, exposing her tight little pucker. I dipped my head down and ran my stiff tongue over her dark opening, twirling my tongue around teasingly and then back up to her clit. The next time down, I parted her entrance with my tongue and deposited enough saliva there so she was properly prepared for my final act. As my mouth found her throbbing clit once again, I slid my index finger deep into her ass, causing her to explode immediately with such an intense orgasm, I was afraid she might fall off the table. I held her in place securely enough that I was able to keep sucking her clit and fingering her tender ass until her body finally stopped shaking and quivering out of control. Afterward she slumped down on the table like dead weight. I stood up and smirked to myself before asking: "So, how was that?" I asked, but received no response. I also noticed that I was already hard again; such was the exciting life of a Personal Sex Education Tutor. I decided to allow my "student" a chance to recover while I went in the house to retrieve some essential teaching aids. The first thing I did was find my old bottle of little blue pills, hoping that they were still potent enough. Just in case, I took a whole pill instead of breaking it in half like I used to do. In the bedroom closet I retrieved a few toys and a set of leather restraints that hadn't seen the light of day for quite a long time. By the time I made my presence known in the backyard, Kendra was sitting up looking somewhat dazed. Her cheeks were flushed and her naked body glistened with sweat. I motioned for her to join me at the bar which offered some shade from the now baking sun. I pulled two bottles of water from the fridge as she took a seat on the barstool. She took a long drink, apparently in serious need of rehydration. "What's in the bag?" she asked. I was happy to know she was still able to speak. "Oh, just a few things you might call 'teaching aids' in case you wanted to continue our anatomy lessons. But maybe you've learned enough for today?" I bluffed. "Well, I really have nothing else to do today," she shrugged nonchalantly, "what do you have in mind?" "I thought I'd let you decide, considering this was all your idea in the first place," I kind of muttered in my best impression of not really giving a fuck one way or the other. "Humph! Well, I kind of thought you were sort of enjoying this too," she shot back. I couldn't help smiling. "Yes I am, Kendra, despite the fact that we really don't like each other very much," I reminded her. "Oh, yeah, well that's right...I already told you I don't really care about you," she replied. "Yes, yes, as long as we're clear on that," I tried to act serious, "so, what do you want to learn next?" "Hmmm, well, to be honest, I've been thinking about losing my virginity, and since we've come this far, I might as well just let you do it," she sniffed emotionlessly. "Wow, that's a big step. Are you sure you don't want to save it for your future husband or maybe a special boyfriend?" "Oh yeah, right! Like that'll happen! I'd rather learn how to do it now so when I finally find someone I like, I'll know what I'm doing," she explained matter-of-factly. Without another word, I opened the bag and began placing the contents on the bar, piece by piece. First the dildoes, which made her eyes widen: "Wow, look at those! And that one's so big!" she exclaimed with genuine excitement. Next, I took out the set of restraints, which she looked at rather suspiciously without putting her question into words. "These are restraints. They are another example of Bondage and Discipline, like being tied up," I explained. Next I produced a thick black leather belt. "This is the Discipline part. I'll use this to warm up your bottom after I put the restraints on you." She shifted nervously on the bar stool, no doubt picturing herself having her ass whipped. Finally, I pulled out a bottle of massage oil and held it up. "This oil will soothe your dry skin and help with lubrication," I told her in the vaguest terms possible. She just nodded and finished her remaining water, perhaps a little too deliberately. "Any questions or concerns?" I asked, giving her the chance to accept or refuse any and all possibilities. "Well, I'm not really into pain, I know that much!" she hinted. "Oh, you mean the belt? Well, I'll let you decide how much and how hard, okay?" "I guess so...I've never been beaten with a belt before," she admitted, her voice falling off some. "You are free to stop anything at any time," I told her, "I'm not interested in hurting you in any way, Kendra. Do you understand?" She nodded cautiously as I placed a folded up beach towel on the bar in front of her. "What's the towel for?" "So you can lay your head down on it," I answered, as I made my way around to her side of the bar. I silently wrapped each of her ankles in the restraints and fastened them to the foot rail of the barstool. Next, I put the two remaining restraints on her wrists and dropped her arms down to her sides and hooked her wrists to her ankles, causing her to slump over. She had no choice but to lay her head on the towel. I could already feel my cock tingling like a teenager in heat. I poured some oil on her back and began to rub it in gently. She seemed to relax fairly quickly as I massaged her shoulders and then ran my fingers lightly down her sides. "Are you comfortable?" "I'm okay. Your massage feels good," she responded. Emboldened, I dripped some more oil onto her lower back and let it run down her captive ass, catching it with my hands before it dripped off. I ran my hands all over her smooth bottom, eliciting some soft moans as she swayed to the soothing motion of my hands. A finger roamed up and down her crack, which seemed to annoy her instantly, for some reason. "You're not gonna tease me to death again, are you?" "Well, I suppose there may be some of that, yes," I admitted, laughing. "Oooooh, you really are a hateful old man! Why did I fall for this?" "We can stop any time," I reminded her. She harrumphed convincingly, but otherwise remained silent, so I proceeded. Now that her shiny ass was completely saturated in the massage oil, I picked up the belt and snapped it in the air a few times for effect. She squirmed but said nothing. "This will kind of relax you and warm you up at the same time," I explained. "You tell me how hard to spank you. If I spank you and you say nothing, I'll do it again the same way. If you want it harder, say 'HARDER' and the next time I'll give you more. But when you stay 'STOP' I'll stop, understand?" She shook her head and then awaited the first blow. Or course, I just had to tease her first. I rubbed her ass cheeks gently and alternately ran the belt slowly over her intended target. "Holy Christ, Mr. Gaines! Just do it, would you? Beat my ass, okay? Damn you can be so cruel!" Again I had to laugh. She was really so much fun to tease! "Okay, ready?" I could see her muscles tense up in anticipation. 'SMACK!' I deliberately gave her the softest possible shot that the belt would make. She said nothing, so I repeated it with the same intensity. After the third whack, she completely lost patience with me. "What the hell do you think you're doing? That's nothing, and you know it!" It may have been nothing to her, but by now my cock was standing tall and ready to salute! "Hit me HARDER! Is that what you want? Do I have to beg for it? HARDER, DAMMIT!" 'SMACK!' I gave her a pretty good wallop right across her ass and waited for her reaction. "HARDER!" 'WHACK!' Another stinger. I waited a few seconds to see what she would do, if anything. Finally: "HARDER!" I reared back this time and swung fully, landing a wicked shot that brought the red out on her ass. She shuddered in response and she exhaled audibly. "Okay, one more just like that one!" she blurted out. 'SNAP!' I laid into her with everything I had, and her ass cheeks tensed up and seemed to stay that way. "Okay, STOP!" And that part of our anatomy lesson ended. I put the belt down and gingerly spread more oil on her tender buns until she unclenched her muscles and began to relax. I made sure enough oil slid into her crack and I wasted no time in rubbing it into her ass and pussy. Surprisingly, she seemed to enjoy this version of 'teasing' and not a cross word was uttered. As I had mentioned to her, this was the part where the belt ultimately caused her to relax. Taking advantage of her new found bliss, I took the medium sized dildo and rubbed it up and down, gradually spreading her very responsive love mound. She moaned a little louder now as she wiggled her ass each time the dildo grazed her clit. With one slight push, half the length of the toy disappeared into her vagina, and again she exhaled deeply as she willingly accepted this welcome intrusion. Slowly and deliberately, I pushed the rubber shaft in and out of her wanton cunt, going deeper with each thrust. Serious groaning ensued, and I knew she was in her glory. So, I stopped and removed it and placed it on the towel in front of her face. "Oh God, I hate your fucking guts right now! What was I thinking, asking you to teach me? I'm an idiot! Grrrr!" Needless to say, I was encouraged by her reaction. And surprisingly enough, she fell silent as soon as she felt the smaller toy poking around her rectum. I already knew that she enjoyed anal contact, but I wasn't sure if she had considered having a real cock penetrate her forbidden territory. We would find out soon enough. But first, I figured I could get a clue with the dildo. She was so slippery with oil back there by now that the toy slid in with no resistance. It was fatter than a finger or thumb, but not as big as a decent sized fully erect cock like the one I was proudly supporting, especially a penis all hopped up on chemicals. A few minutes of thrusting it in and out of her bottom convinced me that she may be ready for the real thing. But first, I had one more challenge for her. I lifted up the Big One and showed it to her as I oiled it up. "Oh no, no, no: that's not going anywhere near me!" She stated with conviction. I explained that it was part of her education. I wanted to demonstrate to her just how amazingly flexible the human vagina was, and how she might be surprised to know how much she could take. I promised that I would stop if she felt any pain. She agreed to try, at least, but she was far from convinced. So I took it real slow. I had to admit, it wasn't as easy as I had thought. Despite all the lubrication, I could feel the resistance coming from her. I suspected she was tensing her muscles and trying to keep that oversized dildo from entering her. Fair enough, I thought to myself: tomorrow's another day, after all. "Uh, Kendra my dear, perhaps you're right. Maybe we should save this lesson for some other time," I suggested, as I stopped and pulled the toy back. She immediately relaxed and she exhaled in relief. And besides, I didn't want my artificially enhanced erection to go to waste. "That sounds good, Mr. Gaines, I really appreciate it," she responded timidly, "but I would like to feel your cock inside of me now, if you don't mind..." Her answer snapped me back to reality, and I immediately began to slide my shaft up and down her exposed girl parts. It felt so good to rub up against her slick openings, and she rewarded me with increasing sighs and moans until she couldn't take it anymore: "C'mon, you evil prick: teasing me again! Damn, you can be so annoying!" she barked out as she wiggled her ass impatiently, "just stick it in me and...WHOA! OH! CHRIST! YES!" I figured I'd kind of catch her off guard by splitting her juicy labia with my more-than-ready cock, before she went into another one of her 'I Hate You' speeches. It worked remarkably well. Her head rose up off the bar, and I instinctively reached out and grabbed a handful of her hair and yanked her head back so she was looking straight up. She seemed surprisingly energized by it, as she pushed back against my pelvis in rhythm with my forward thrusts. I must admit, fucking her tight (technically) virginal pussy felt incredibly good, and it was clear that the feeling was mutual. I held her hair in my fist as I slammed into her again and again with so much enthusiasm that her bar stool was up on its two front legs each time I buried my grateful cock deep into her young cunt. I think she really wanted to do her dirty talking to me (which I loved!) but the best she could muster was a series of "UGHS and OOHS" and other guttural grunts that were difficult to interpret. It was clear that she was enjoying her initiation to one of the most intimate and moving anatomy lessons of all. Having supplemented my own vigor with that little blue pill (which I hadn't used in years), I remembered that it would take me a very long time to finally ejaculate, and that I could go on for quite a long time without losing my hard-on, and so that's what I did. I just kept silently pounding her pussy, delighting in the sight of my erection disappearing deep into her quivering body without any indication that I might slow down. I took note of some drool coming from her mouth and dripping onto her breasts, unbeknownst to her. It really turned me on for some reason. I figured it was a sign that she was zoned out and concentrating on getting the first real fuck of her life. We were both dripping with sweat in the humid air, despite being in the shade provided by the bar roof. I thought I heard her whisper something that was hard to understand, given her parched mouth and throat. It sounded like 'fucking ass', and I figured she was getting ready to spew a string of insults at me. As she licked her lips her words became clearer and I was surprised but what I heard: "Fuck my ass! Put your hard cock in my ass, PLEASE! I want you to fill my ass up, you no good for nothing tease!" I guess I shouldn't have been that surprised, considering I'd already been violating her ass without warning, both digitally and orally, and she seemed to respond positively each time. So, I let her hair go and put both of my hands on her ass. Her head immediately plopped down on the bar. I squeezed and kneaded each cheek, playfully pulling them apart as I continued to fuck her cunt without let up. The cool rush of air hitting her exposed rosebud elicited an involuntary 'OOH' from under her breath, and she pushed back against my manhood in response. "Fuck me in the ass NOW!" she demanded, causing me to smile to myself, already knowing what I was going to do next. I slowed my tempo to a crawl as I gradually pulled out of her vagina little by little. I knew she would grow impatient, as she was wont to do, and I wasn't wrong this time either. I could hear her getting more and more irritated with my dallying, and she shook her ass back and forth, trying to dislodge my cock completely. "Oh My God! You are soooo frustrating! It's no wonder why I fucking HATE YOU! Why do you keep torturing me like this?" She was almost shouting, much to my delight. I finally relented and pulled out completely, but I started rubbing her clit with my thumb, which silenced her temporarily. She sat stock still for several seconds until her body trembled and shook uncontrollably, and I had to lie over top of her and hold her in order to keep the bar stool standing upright. I irritated her clit unmercifully as she exploded in such an extreme climax that only the young ones with their raging hormones experience. It seemed as though she was a rag doll after that. The only detectable movement came from her heaving lungs struggling to replace some much needed oxygen. She didn't try to speak for several minutes, and I used the time to continue making her hate me. My cock showed no signs of fatigue and so I slowly ran it up and down her slick butt crack while she recuperated. I was surprised that I was getting even more excited than before. I realized it was because of the exquisite anticipation of anal sex. I tried but failed to remember how many years it had been since I fucked someone in the ass, and now that I was presented with the opportunity, no: it was being demanded of me, I was downright giddy. "WELL?" Ah, she was back, and stronger than ever. "Are you going to service me like I want, or are you just a big fat fucking jerk who likes to tease a young girl to death?" 'Service her'? I wondered where she came up with that term, but I liked it. After such an extraordinary orgasm that she didn't even acknowledge, now I was just there to service her. I admired her moxie. She had all the makings of a Dominatrix, I thought. But that was a lesson for another day. I spread her ass cheeks and put the head of my cock directly on her forbidden entrance. She settled down in anticipation as I took my good old time entering her. The head went in slightly and then I pulled back, repeating this process several times. Groans of frustration ensued. She lifted her head up and looked back at me as well as she could. Daggers shot from her eyes: "You know, if I wasn't tied down like this, I'd take that belt of yours and beat your fucking ass until it was raw!" she threatened. I couldn't help but laugh out loud, which apparently she didn't appreciate. "OOOH! You are such a mean man! And you wonder why I hate your fucking guts?" With that remark, I slid my shaft into her rectum with some authority, although not viciously, by any means. Her head shot up off the bar, but she said nothing. In and out, I began to fuck her ass in earnest, holding tightly to her hips as I rocked forward and then back again, until most of my penis was inside her. I marveled at how the temperature inside of her rectum was surprisingly hot, and it felt really good surrounding my member. We settled into a firm and steady rhythm, and it wasn't long before she cooed and purred and even giggled in delight as she felt her anal desires satiated. "Is that all you've got old man?" she looked back at me, grinning from ear to ear. Emboldened by her challenge, I lunged fully into her ass, slamming my thighs against her bottom as I fucked her with all I had. I let go of her hips and reached under her body and cupped her tits in my hands. Squeezing her nipples between my thumbs and fingers excited me as much as it did her, and she moaned long and loud as I continued to pound away. I was in a groove now, and I could feel my juices getting ready to squirt. Without warning, I pulled straight out of her ass and buried my stiff manhood deep into her pussy and didn't miss a beat. 'OH!' was her only reply. I took her completely off guard, which further excited me. I wanted to 'punish' her for all of her naughty put downs, and I'm sure she didn't mind in the least. It was going to happen soon, I knew, so I pulled out and slid my throbbing dick back into her ass, causing her rear end to shiver and spasm, while she could only muster a weak 'Mmmm' in response. Back and forth I went: pussy, ass, pussy, ass, and she pushed back with each stroke. It was finally time to shoot my load, and being the gentleman that I was, I gave her the option: "Where do you want it, princess?" She knew exactly what I was talking about: "Oh, cum in my ass, please! I want to feel your hot cum fill my ass!" Request granted: I pumped my load of jizz into her sweet young rectum as I continued to bang her bottom for several more minutes beyond, and long enough for her to match my orgasm with another strong performance of her own. - - - - - - - - - After a brief period of recovery, I undid the restraints and set her free. It took several minutes for her to be able to loosen up enough to sit up straight and to finally stand. I helped her to the pool and we both fell in at once. We lay there side by side, just floating and cooling off, silently holding hands like we had just been through an intense life encounter together, which we had been. Finally, she looked over at me with an amazingly sensual look in her twinkling eyes and simply uttered: "Wow!" We got out of the pool and I helped her dry off. She put her bikini back on while I dried myself off, not bothering to put anything on. As she headed towards her house across the street, I walked with her. What an amazing girl, I thought. She certainly knows what she wants! We stopped at the front of my house, and she turned towards me, holding my hands in hers. "Are you free tomorrow?" she asked. I nodded and smiled. She turned and began walking away, and then she looked over her shoulder: "Thanks for the lesson!" "It was my pleasure!" I replied. And then she stopped and turned around: "Oh: and...I really don't hate you!" "That's good to know. I really don't hate you either, Kendra!" She smiled: "Thanks Carl!" And I just stood there and watched her as she made her way down my driveway and across the street to her house.
