Diana was my wife's 18 year old niece, and in the summers, she'd come for a two week or so visit. For some reason, Diana confided in me, and was not afraid to tell me about her sexual exploits. She apparently lost her virginity to some Italian guy, and had given blowjobs to a few guys. I thought it was funny that my wife's niece was just the opposite of her; my wife would die if she heard half of Diana's stories. Diana was a tall and lanky girl at 18, with long legs and small, pert breasts. I had been married only 6 years to my wife, but the thought of fucking my young niece was a huge turn-on.
One night, the three of us were up watching TV and my wife decided to go to bed early. No sooner than my wife shut the door of our bedroom, Diana excused herself and returned about 5 minutes later wearing this thong bikini. I about died. "I wanted to show you this," she said, "I didn't think Aunt Barbie would approve." No, she definitely wouldn't! I muttered how sexy she looked and couldn't help but lock in on her perfect ass. My cock twitched immediately, and Diana could see I was getting turned on. She jumped into my lap and nuzzled her head against my shoulder. I couldn't help but put a hand on her soft ass and cop a quick feel. "Do you think I'm hot?" she sighed, wiggling her butt as my hand squeezed it. "Hell, yes!" I said, so quickly she had to laugh. "In that case, why don't we go to my room and fuck?" As she said that, her hand dropped to my crotch and began fondling my now growing erection.
I was at the point of no return. Do I do the right thing, and brush my niece aside, and scold her for her behavior? Or do I give this little tease what she deserves?? My sex life as that point was more frustration than pleasure, as my wife was older than I and didn't have the desire I had. I figured what the hell--the odds of me getting another chance at 18 year old pussy was slim to none! I lifted my niece up and carried her to her room, and shut the door. "I think we both can use a good fuck. We have to be quiet, as Barbie will hear us," I told her, as we began to strip. Diana had a smile on her face as she watched my cock come into view. I have a thick 7.5" incher, and she eagerly grasped it as we kissed. I cupped her soft ass and relished the sight of her young body.
"Why don't you show me what you're learned?" I asked her, and she knelt down as I sat on the edge of the bed, my legs parted. Diana took my cock into her mouth and her tongue did a number on my cockhead, which felt great. For an 18 year old, she obviously had learned quickly! I asked her to lick my balls, and then I stood up and began to fuck her mouth. I was a hot sight to see my niece on all fours, pleasuring me that way, and I felt the pressure build in my balls. When she ran her finger into my asshole, I lost it, and blew jet after jet of spunk down her throat. She almost gagged, and spit most of it out, but licked her lips and tasted some of it. "Very nice," I said, "but it's your pussy that I really want."
Diana laid back on the bed and spread her legs, showing me her tiny slit. I was amazed at how different it looked from my wife's, and I just KNEW she'd be tight as hell. I tongued her pussy for a few minutes, opening up her folds, and ran a finger up her channel. She wiggled in delight, and yes, she was very tight. This was going to be good!
I got on top of her and rubbed my bulbous cockhead against her slit. She grew impatient and begged me to put it inside her, but I wanted to grow her lust. I put the tip in, then pulled out, then put it back in, and out, till she literally thrusted upward, impaling half my cock inside her. "Oh, fuck, yes!" she barked out, and I froze. It was so loud that I thought for sure my wife would awaken from the dead, and catch us in the act. However, Diana could've cared less, and she grabbed my ass and pulled me to her, her fingernails jutting into my asscheeks. At that point, I didn't care what my wife would do, and I slammed my cock all the way inside her. The tightness of her pussy was amazing, and when I pulled back, I could feel her cunt muscles working my length. Diana was gasping out as I pumped her, "Oh, hell, Uncle Keith, your dick is so big!" The passion I felt that that moment was incredible--I was a man possessed. I was screwing my young niece's raw pussy, and she was loving it. I decided to change positions to avoid cumming too fast, and put her on top. She slid down my length, groaning in a deep voice. I slapped her ass and had her lean over so I could suck her nipples, which were very sensitive. She came quickly, and the clutching of her pussy on my meat was out of this world. Her vagina was in full spasm mode, and she almost brought me along with her.
When she finished, I rolled her onto her stomach and grabbed her hips, literally holding her up off the sheets. Diana was much lighter than my wife, and I loved how I could move her around the bed with ease. Her ass looked so good from my view, and I speared my rod in and out of her pussy with authority. She was moaning pretty loudly now, but I didn't care. This was the fucking I needed, and if my wife awoke and found us, she'd just have to watch us finish. I stroked Diana for what seemed like an eternity before I realized I hadn't yet cum! I rarely lasted five minutes with my wife, but with her, it was sex to get it over with....this was sex to relish. My balls were aching, though, and when my concentration broke, my cock let loose, spurting wad after wad onto my niece's beautiful ass. I watched as my jism drained down her asscrack and onto her stretched pussy lips.
Diana kissed me and gave me a look of respect that I rarely saw from the Mrs.. My cock was still rock-hard, so I grabbed her hand and pulled her out the bed. She was so light I couldn't pass up on a chance to fuck her standing up (one of my favorite positions). I put my hands under her tiny ass and lifted her up. She cried out as my cock split her folds and we kissed as she lowered fully onto my rod. She bounced up and down with some help from my arms, and I was in heaven. Her pussy felt so damn good...it was so good to be fucking a teenager again. She came in no time, but I just kept fucking her. My thighs were starting to ache, and my arms were tired, but my cock was ready for more. I was staring into her eyes as I fucked her, and the pleasure on her face was such a high for me. I lasted a few more minutes before I finally gave out and blew my juices into her, my knees buckling in the process. As I laid her back done on the bed, she put a hand on my chest, and sighed, "That was fantastic! No one has fucked me like that before."
We collapsed on the bed, and I wondered if our night was over. Diana, thankfully, had a mind of her own, and she wanted to suck my cock again. I laid back, and spread my legs to give her ample access. Her lips were very talented, and my cock throbbed against her tongue. I held out as long as I could, but my young niece extracted another load from me, and this time, swallowed every drop. I was exhausted, and the look on Diana's face was the same. We snuggled up and almost fell asleep together; luckily, I got up, tucked her in, and joined my wife in bed.
As luck would have it, my wife woke me up early, around 5am, and took advantage of my morning hard-on. I had to wince as she sank her cunt over my meat, but soon I was thrusting upward and filling her pussy with my big cock. "Be quiet," she sighed, "Diana might hear us." I smirked, and said, "Something tells me Diana will sleep in today." I shafted my wife to two orgasms that morning, and as I did, wondered when my next session with Diana would be.
