Note: This story was dynamically reformatted for online reading convenience. I arrived at my girl friend Sharon's house around 7:00. It was her birthday, and I had promised to show her a good time by being her sex slave. She is 10 years older than I, and enjoys playing games, dominating me for one. I like it too, it's fun to play with her. She makes me do things and pinches my nipples, sometimes she will even spank me. We also fantasize together, and make each other all sorts of promises when we play. The last time we were together I promised I would suck a man's cock for her on her birthday, we have often talked about her watching me suck a man's cock, but it has always been fantasy. When I arrived, it was pretty much as usual. She was dressed in something skimpy. She has big tits that hang, and large nipples. She also has a little belly, not really large, but not skinny either. Maybe she could be described as having a generous figure. I find her very sexy and attractive, and there is something about her being older than me that turns me on. As usual, she asked me strip down to my bikini underwear. She had quite a collection for me to wear, some of them very skimpy, today, she had me wear a pretty normal pair of bikini pants. Not the real skimpy type with the string that goes between the crack on my ass. So were playing around, and she reminded me of my promise to suck a cock, she was playing with my nipples at the time which drives me crazy. But when she said, "I want you to meet Jack," I opened my eyes and saw a very strong, masculine man standing there smiling at me. She kept playing with my nipples, pinching them and said "Remember you promised, now I want you to show me how you will suck Jack's cock. I went to a lot of trouble to get him here, and I promised him you would do it. I said I didn't think I wanted to. Jack quickly said he could make me do it, but Sharon wanted to bribe me, so he continued to do things to drive me crazy, pinching my nipples more, showing me her big hanging tits and stroking my crotch, which was still clad in the briefs. Jack even reached over and stroked my crotch, and started playing with the other nipple, pinching it a little harder than Sharon did. But I would not agree to it. Finally Jack lost patience, and even though Sharon wanted to try more, he grabbed me and put me over his lap. I was there before I realized what was happening. He didn't pull my briefs down, but I felt him remove his belt, which certainly upset me. He asked me if I was going to ask for a hard spanking and pull down my briefs for him, naturally I told him no. He didn't wait more than a second, When, that belt hit my backside really hard, two, three four times. He then informed me that if I would cooperate and ask for a good spanking, he would do it with his hand, but that I would also have to agree to suck his cock so Sharon could watch, and then I would do whatever they wanted me to. And speaking of Sharon watching, she had moved over to where we were. I could see she had parted her legs and was fingering herself and pinching one of her nipples. It was obvious that this beating was turning her on. My ass was burning, but I didn't say anything, so Jack said, "I have all night." And he hit me again, after about 10 hits, I screamed that I would cooperate, and mercifully, the beating stopped. He said, are you sure, because if you change your mind, I'm going to whip you until I take your panties off with my belt. I told him I was sure, and I was really afraid, but you know, there was one weird thing, I had this big hard on. Sharon could see the bulge in my pants, and said to Jack, "I think he likes it, he has this huge hard on. He then told me to ask for a spanking, and that I also had to apologize to him and Sharon for taking their time, and the entire plea really ought to be good and believable. I said, "I'm really sorry for not cooperating, and I know I have been very bad and have to be punished, so Jack, would you please give me a really hard spanking on my bare bottom, while Sharon watches, I will be happy to pull my panties down for you so you can spank my bare bottom." He said that he would be happy to spank me. He also said he would let go of me, but I had to promise not to try and get away. Then he said, "If I do as you ask and give you a really good bare bottom spanking, how would you like to thank me for that. I told him that if he would let me suck his cock, I would really like to thank him that way. That would be good he said, now sit up for a second, I want to see this hard on you have. So I got up off his lap, then sat on his legs as he patted them with his hands. He pulled my legs open a bit and pulled the front of my briefs down to expose my hard cock. "Well look at that, you have a hard on, I think you like being manhandeld like this, and I'll bet the thought that you are going to have to suck my cock is turning you on." Sharon agreed with him, "Jerk him off a little she said" He pulled on my cock a little. then he reached up and pinched my nipples, it really turned me on. He started jerking it off for a while, and then a bead of clear liquid formed at the head. Do you like it when I play with your cock and pinch your nipples? I said I liked it. Do you really want that spanking? As he said it, he pinched down hard on my nipple, I quickly said that I wanted it very much. OK, enough of this, put yourself back over my lap and ask me nicely for that spanking agian. So I again got over his lap and asked him to please spank me for being bad. He told me to pull my panties down for him, so I reached back and pulled my briefs down to my knees. He said to me, you are going to count. So I started counting, and after each number I counted out, there was a very hard smack on my bottom. Not being satisfied enough, Jack said to me, "Stick your ass up higher if you really want this spanking, so I lifted my ass up and stuck it out. That was rewarded with more hard slaps. After 30 of these, my bottom was burning, and he pushed me off his lap. Well..... are you going to thank me for teaching you your lesson, and make it good, be creative. "Thank you for punishing me, I know I needed it, and it was good to have Sharon see it. I'm glad you made me pull my panties down and spanked me hard. Now can I thank you further by sucking your cock? Jack smiled and said yes. He was fully dressed, so I had to reach over and unbuckle his pants, open them up, and slip them down, then pull his boxer shorts down to expose his already hard cock. Sharon moved over to get a closer look. Sharon said to me, "OK, open your mouth now, but instead of a cock, I got to clean off her finger that had been fingering her cunt., stick out your tongue and lick it. That's right, lick it all over and clean it off. Then she brought over one of her tits and had me suck that, then she told me to lick Jack's nipples, as it turned him on. I put my mouth to one nipple and licked it, then the other one I played with by doing little pinches with my fingers. "I think you are making him very hard now, that's good, keep it up a a little more.... OK, now you are going to suck it. First I want you to kiss it, so I got down on my knees and got between jacks legs. He held his cock with his hand, and I brought my lips up it and placed a kiss on the tip. Now put your lips around it. I opened my mouth and placed my lips around the head of his cock. Now move your tongue around and make it wet, which I did. Now move your lips up and down, bring it in and out of your mouth like he is fucking your mouth. Now don't you like that? I nodded that I did. Jack who was impatient with the whole thing, let her direct me, Sharon reached over and started playing with my nipples, and I reached up and started playing with Jack's nipples which obviously turned him on. Sharon said to me then, "You do that very well, are you sure this isn't your first time. Now what does this make you if you are sucking Jack's cock. "A cocksuker I said." That's right, you are our little cock sucker and cunt lapper. I did this for a while, then in typical male fashion, he just reached down and started to jerk off in my mouth. Stick out your tongue.... I did, he rested the base of the tip of his cock on it and just jerked off. You know what you are going to do when I come, don't you. I said I did. He asked me what that was. I will put my lips around your cock, and let you come in my mouth. What else, Jack said. I will swallow your come. I knew that was what Sharon wanted. I didn't have to wait long. He pulled my head forward, I wrapped my lips around his cock and took the jets of come, then swallowed them as best I could. Sharon who was still playing with herself wanted to see what was left in my mouth, so I showed her. She said I was being good and because I was, she would let me fuck her. I was really horny as hell, so I didn't really didn't have to be convinced. She lay down on the edge of the bed and opened her legs. Now lick my pussy. I got down on my hands and knees and licked her pussy, and made it all wet so I would slip in easily, then I pushed my cock in her pussy. It felt so good. While I was fucking her, Jack came over and watched bit, and sharon reached over and grabbed his cock again. Play with Jacks nipples and see if you can get him hard again, I want to see you suck that cock again. She started pulling on his cock and I reached up and tickled and pinched his nipples, and again it started to get hard. "Ask Jack nicely if you can put his cock in your mouth." I said, "Jack, could I please put your cock in my mouth again?" He smiled and said sure. Open your mouth, I want to watch it slip in to your mouth, so again I opened my mouth. Jack pused his cock past my lips and I took it into my mouth. Move your tonge on it, turn him on, reach up and play with his nipples so he gets horny. I did this as best as I could while I fucked her. But he pulled away. I thought he went to jerk off, but then I felt a hand on my ass, it was Jack. He had got a Vaseline bottle, and had some on his finger, I could see because he was showing Sharon, she just smiled and nodded. I then felt the finger in the crack of my ass, moving up and down with the Vaseline, looking for the hole, which he found. Jack pushed his finger in a little, then got a little more Vaseline, I knew he had gone back to the jar because it was cold. Then I felt his cock against my ass, I was all the way in Sharon. Sharon said to me, listen baby, if you want to continue this fuck, you are going to have to push your ass out on Jack's cock, so it goes in, and if you don't, jack is going to whip the hell out of you. So I slowly pushed my ass back also pulling my cock out of Sharon, little by little , I could feel the pressure of his cock against my hole. It started to go in then I continued to move back on it, forcing Jack's cock in me, when I pulled forward to go back into Sharon, Jack moved forward also, so the next time I pulled out for a stroke, I was further impaled on his cock. When it was all the way in to the hilt, he started to fuck me while I was screwing Sharon. Then he reached around and started to pinch my nipples.
