Mag-log in"Cheryl. Jenny and I have been working out for almost a year. You can thank her that our sex life is so good - she's the one that got me into the gym, nagging me. As my workout buddy, we take each other's measurements every month, with calipers to check bodyfat. You know we do that half-nude, stripped to our underwear. We've become good friends, but there is almost no sexual tension between us. If I massage her butt, it's to take the soreness out of the muscles. If I massage YOUR butt, it means I intend to lay some pipe, and pretty damn soon."She giggled a bit at that, but strangely the laugh turned into almost hysterical weeping."Cheryl, I didn't screw your sisters butt." I said this vehemently, and honestly."Oh, I believe you. I almost wish you had. You know, she hasn't been on a date in probably 4-5 months. She's only been going out with Marisa, and now I think Marisa is moving in with her." she was still sobbing."So?""So, Marisa is bi; I think Jenny is turning gay.""Come on,
"Ohhhh, yesssss," I hissed as I loosed my first stream of cum on her chin. She was leaning her head back as I loosed several long sticky streams of cum all over her face. Her eyes were closed, good thing, because one stream stretched from her hairline, right down her left eye to her mouth. She finally took my sensitive cock head gently between her lips and cleaned me. Cum was dripping down her cheeks and she was giggling as she finished sucking me off."I hope no one catches me hopping into the shower," she laughed, and without another word, headed into the girl's shower.I turned to take my shower. Entering the tiled area, steam was billowing out of one stall, where I could see Jack was cleaning up. I took the shower stall across from him.I knew Jack moderately well. Jack was attending college nearby, working on his MBA. He was the guy who took my first application to join the gym, and showed me around. Most of the time he worked the late shift, but I guess he had swapped with Miche
"Good. That is the basic exercise. The slight lean will work the glutes more than the other muscles. Now two more secrets. Start the exercise with your abs and glutes tensed, and at the bottom, hold it for about two seconds, and squeeze your ass really hard as you push back up."I held my hands on her ass, to feel that the muscles were doing as expected. She was such a good student; she did it perfectly."Ok, now we'll let you feel some weight. I want to find out just how much weight you can squat." I loaded the bar with 120 lbs. Combined with the weight of the bar it was close to 160 lbs. She managed it, but it was clearly difficult. "That's great, can you take any more?""Maybe, a little," she admitted.I added ten more pounds and gave her a two-minute rest. With just a little help she managed two. "Great. That tells me that your normal workout should start with 80 lbs. for fifteen reps, and ending with 120 for six to eight. If you can do more than eigh
"Jen, if you want to get a round butt, you've got to tailor your workout to it. The workout you're doing now will do the opposite if anything. Endless cycling and light dumbbell work won't do jack for your glutes."Whereas I'm a voracious reader, and study everything I delve into, Jen avoids books and reading outside of school. Once I picked up bodybuilding and working out, I read dozens of books, and researched everything online."Let me work out a plan for you, I'll do a little research, and Monday we'll start a program that will have your pants filling out in back, and the guys pants filling out in front." During our discussion the inevitable had happened, and I was screwing her in a quite leisurely fashion. I was still stroking her sweet ass, occasionally teasing her tight little butthole with my finger."If you can get me a round bubble-butt, I'll give you something." Jen answered warmly, grinding back on my insistent cock."And that would be..." I p
After my initial conquest of Jen (documented in "Jen and Me: Sis-in-Law Rewards") things were a little awkward between us. That first weekend had been fantastic, and the sex was raw and uninhibited, but where did it go from there? We had said all along we were just doing this as friends, but there's something about screwing your sister-in-law five times in a period of less than 24 hours that changes the relationship a bit.After the scene with Marisa ("Jen and Me: Descent into Narcissism") it was clear that we were crossing some kind of boundary, and were more than just friends. I must say however that Dr. Barton is a genius, and once the swelling and black eyes went away her nose was perfect.We weren't just balling indiscriminately. We did stick to the rules, and we always found some excuse, some bet or little incentive, to find our way back to t
When she had about half my cock up her ass, she started fucking herself with it. She first raised and lowered herself an inch or so, then about two inches, until she was driving about 3/4 of my cock in and out of her own ass. With one quick movement she finally slammed her whole body down, driving my cock up her ass to the base. "Aaaaarrgghh," she screamed out as she did it.With my entire cock embedded up her butt, she laid back on my chest, holding my cock, and squeezing it with the muscles of her butt. I could maneuver about two inches of it in and out of her in this position by rolling my ass back and forth. I kissed the side of her face, and rubbed and massaged her incredible breasts. Her breasts had huge aureoles, and her nipples were hard and long. I pulled and tweaked them. Looking down, I saw Jenny repositioning herself, then she was going down on Marisa, licking her pussy like a kitten at milk. Her fingers were rubbing Marisa's clit a mile a minute, as her tongue de
No force on earth could stop the huge, beaming grin from forming on my face. He lifted his head up, eyes widening as he stared at me. I wondered what he saw when he looked into my eyes. I felt charmed by him suddenly. Of course, my crush for my brother had started years ago. But this was way beyond
The girls lead me to the bathroom, where a shower was started. I was starting to get a little worried at the idea of these girls approaching me with razors. They were fiends, shaving my arms, legs, chest, stomach, and finally trimming all the hair away from my cock, except a little patch just above
Then there was the biggest, most telling advantage of all. These bikes had gears. The gym ones didn't. Where we had been biking, down by the river, Jenny never had to change gears. Her knowledge in this area was almost non-existent.The race started out with a series of twists and turns through a p
And Jack Makes ThreeOk, when I last put pen to paper my wife had encouraged me to have sex with her sister, and wanted me to get Jenny a boyfriend. I had some ideas there I was looking to test.Oh, yeah. And my sweet little sister-in-law had talked Cheryl through her first anal experience. And to
