Sexy Cousin Part Two

Beth introduced me to a girlfriend in highschool. They shared clothes a lot. When I'd fuck that girl I always wanted her to leave as many of Beth's clothes on as possible. This was before Beth and I ever fucked. Sometimes I could smell Beth in her clothes. Then there was the night me, my girlfriend, Beth and her boyfriend drove to the country to fuck. He put up a blanket between the front and back seats so we couldn't see each other. But I wanted to see!. I was so close to my hot cousin getting boned in the back seat, I got too excited and came in my girlfriend in less than a minute. They made fun but what could I do? Tell them the truth? I knew Beth was hot for me but that girlfriend had NO bisexual tendancies at all. It might have broken us up. So a bird in the hand...
The second time I fucked Beth, fast forwarding to my first wife again, Beth was pregnant. So I didn't have to worry about getting her pregnant. I didn't get to cum in her the first time for that reason. Also, coming in Beth, that was my ex-wife's line. A line that, if not crossed, my ex didn't consider it cheating. But I was hell bent on cumming in Beth if I could get permission or do it secretly. We drove behind an old school in the country and got into the back seat and started messing around. My wife suggested Beth climb on top of me, a position we hadn't done the first time.
Beth started riding me with everything she had; pregnancy hormones being what they are. At one point my wife got jealous or felt guilty and exited the car. "Here's my chance!" I thought. Beth loosened up, emotionally AND vaginally. I let go too. Within moments I was cumming in Beth. BETH! My cousin had my load inside her. I came for the longest time. All along I was keeping my breathing as normal as possible, avoiding thrusting my hips. Hell, Beth was doing enough of that for ten people. It was probably the longest orgasm I have ever had. Owed to it being with my cousin in part. But also maintaning control might have actually contributed to my relaxing and extending the orgasm. At any rate, my cock just kept pumping and pumping. When I was good and done I didn't let on. I just let Beth continue, I would be hard for several minutes. So I waited for Beth to cum. Something I never had to wait too long for; seems she was as into our i****tual relationship as much as I. She quivered and bucked, out of breath from doing all the work. She slowed down, catching her breath for what would no doubt have been a second round of her trying to rip my cock out by the roots. I said, "Maybe we should stop." As if I was worried about what my wife was going through (NOT). Beth raised up off of me, my load pouring all over my crotch. When I got to my wife she asked, "Did you cum?" I lied of course. I got lucky, my wife never checked to see. To this day I believe I'm the only one who ever knew I came that night...until now!
I would have a few more chances to fuck Beth. Each time was as good as the last because you don't get used to the forbidden fruit. It's always exciting. The next time I would have her all to myself!
