It was twilight out but I had plenty of light to see by and the neighborhood was not the sort that made you worry about serial killers in the bushes or some such. So walking down by the trails tramped by years of kids feet I made my way out to the creek. Just killing time, thinking of pussy and wondering what I might say to Rachael when we spoke on the phone. The creek itself was fairly secluded in the woods but there were some spots where the road came near it. As I walked down by the side of the trail and I got near one of the parts where the road came close I saw what looked like car brakelights. They flashed for a moment and listening I could hear the sound of an engine which then turned off. It struck me as unusual for someone to pull their car into a place like this, so I approached quietly. Above the sounds of crickets chirping I could hear the sound of two people talking one male and the other female. The car looked familiar as I got close, I snuck my head around a tree for a better view. It looked like Tommy's dads car, and it dawned on me what he had said yesterday about how he was fucking Rachael's mom on the side. Looking closer I saw a dark haired woman climb into the backseat pulling off her shirt as she went. Sure enough Tommy's dad climbed in behind her and I heard the sound of a zipper go down, and watched as Rachael's mom bent over in the back seat and the older man climbed onto her from behind. From where I was standing I could see her face as he pushed into her and her eyes did something similar to what Rachael's did when I slid into her. She had a face one could define as exotic. She had a prominent but geometrically perfect nose. Her lips were full and her eyes were big. She looked like a photo of a movie star from the 1940's Her dark hair had waves I could see and she seemed to style it to look like an old school pin up girl. I could feel my cock rising as I saw her move with the mans thrusts. From where I was standing it looked like she was having fun. If she wanted to she could have rolled her eyes or looked bored if she wasn't into it. Instead her eyes looked around as if they needed something to focus on. My hand found its way to the front of my pants and as the woman made ooohing sounds from the back seat I let myself loose into my hand. It was too good a show to miss. So I stood there stroking as the wet sounds of their fucking made their way to me. I was enjoying the show so much that I almost failed to notice when she spotted me. My eyes were half open when they met hers. She looked surprised for a moment, and I thought she was going to freak out. Then to my surprise she smiled and winked at me. Her eyes goaded me on, so I showed more of my cock from behind the tree and kept stroking. Her smile got wider and she licked her lips as I worked myself in front of her. Soon The older man behind her started making deep sounds, then pushed deep inside of her and held still. As he did I brought myself off onto the ground and she seemed to shiver. As her eyes opened she smiled at me and I pulled back. Good timing as they put their clothes back together and got into the front of the car in quick order. I watched as she got out turned her, head looked at me and dropped something on the ground behind her. I waited for the car to leave then moved up to where it had been looking for what she dropped. I found them in the grass next to the ruts the car had made. My hand felt soft fabric and I pulled up a balled up pair of black lace panties. The area toward the front felt moist and I ran my finger inside of it. I could smell her musky scent from them and for an experiment I tried the taste on my finger. Muskier and somehow tastier then her daughter. Grinning I put them in my pocket and walked back to the house. Mom and Dad were watching tv and I waved absently to them. They smiled and I walked up to my room. Once inside I shut the door most of the way and walked to the bookshelf across from my bed. I reached out and grabbed a copy of a Harry Potter novel, something I knew my parents would never read. I had carved a space out in the book to hide some things. Discs of porn and a few other goodies. Now I stuck the pair of panties into there. They belonged to a woman whose name I didn't know whose child I was fucking and who had enjoyed watching me masturbate to her having sex. Frankly I thought I was falling in love. Grinning I grabbed my cell phone and dialed Rachael's number. The phone rang a couple of times and then I heard Rachaels pretty voice on the other line. "Hi." She said cheerfully. "Hi Rachael, it's Mark." "Oh hi Mark, how are you?" "Really good, had an odd encounter a little bit ago." "Really? What happened?" She said in a expectant voice. So I told her about my walk, the car, the lady who I described and her leaving her panties aside. "Oh yeah that was totally Mom." Rachael said. "Mr Anderson likes to get some before he comes home from work. So Mom meets him at a local diner and they drive off for a quickie. Apparently he pays well though." "Looks like shes worth it." I said. "Yeah shes pretty isn't she, I hope I wind up looking like her." "You're pretty now." I replied, not wanting her to feel bad. "Ohh I know that but shes lady pretty I'm girl pretty. I can't wait till my tits grow out." "I bet those are gonna be fun to feel." I said in reply. "Well when they do I'll let you feel them." She said with a giggle. "I am looking forward to that." I said honestly, I'd happily keep fucking her though her development. "Good, your nice and you're fun I like you. You can stop by to play whenever you want." "Ohh why thank you, who knows maybe I'll sneak out some night." "That would be fun, you could come into my room and wake me up." "I wonder how I'd do that." "Well you could do what you did yesterday that would make me really happy to see you." "Trust me you can talk me into doing that pretty much whenever you want." "Good." From the bottom of the stairs I heard my Mom yell my name. "Mark can I talk to you for a minute?" "Rachael, I gotta let you go, my mom wants me." "Okay, I'll talk to you later." I hung up on her and headed downstairs. Mom was at the bottom of the stairs holding the house phone. "Mrs Anderson just called, apparently her mother is not well, So she and Tommy are heading upstate to help for the next couple of weeks. She wanted to know if you could stop by to let the dogs out around noon while Mr Anderson is at work?" "Yeah sure I could do that." Mom lifted the phone. "Mark said he'd be happy to do it. Okay thanks." She hit the end button on her call, and looked at me. "She left a key under the backdoor matt, and she left some money for you as well." "Well that was nice of her." I said. "Try not to spend it all at once young man." Mom said and ruffled my hair. Then walked back to join Dad by the TV. Walking back upstairs my phone rang. Looking at it I saw it was Tommy. "Hey Dude, I got the news." "Yeah it sucks, But I'll be back in a couple of weeks. When I get back I want a day with Rachael all to myself." He said quietly. "Sounds fair to me." "Cool, gotta go pack my stuff but I'll talk to ya later, let me know if anything cool happens while I'm gone." "Okay will do." "Like the fact that I have the panties of the lady your dads fucking?" I thought, but I figured I wouldn't bring it up. It seemed a little touchy to mention. I walked back into my room and opened the book looking at those panties. I felt myself hardening again, so I prepared for bed and made sure the tissue box was nearby. As I worked the length of my shaft I wondered what fun I would have with Rachael tomorrow.
