It's true. Jen has converted me into a total gym rat.
It's been four months since my original conquest of my hot little sister-in-law. Through various bets and incentives, we've made love five more times. She is really playful in bed, and we have a great time. After ten years, I'm finally getting to know her. It's only since she lost the bike race that we've really talked a lot.
On the other hand, we're spending less and less gym time together. I'm really working at building up some mass. I've never liked my sloped shoulders, so I've gone to spot training the delts once a week - mostly dumbbell overhead presses, and upright rows, with some flys thrown in.
Forty has come and gone, and I've just had to renew my gym membership. My bench hit 300 lbs, and my arms are over 19 inches. I'm feeling great, and I've really transformed myself. Some of the heavier lifters are working with me now. I'm learning about exercises that shape the muscles. I've only been bulking up until now. My time in the gym is closing on two hours a day, five days a week.
I think Cheryl is occasionally bothered by the time I spend in the gym. But I've cut work back to eight hours a day, so I'm spending almost as much time at home anyway, and since I got down to 220 lbs., and she hit 135 again (even lighter than when I first met her) our sex has been great. She's even become more adventurous, and has wanted to play some light bondage, fantasy games. She's even hinted at swinging (!) a little with a couple of friends.
I'm happy, and feeling great, Cheryl seems happy. Unfortunately Jenny is not as happy as she should be.
"I don't get it," she was telling me, during our latest 'exchange' day (when we exchange 2 hours in the gym for a couple of hours in her bed.) "You have completely redesigned yourself. You have a sexy as shit 6-pack, gorgeous arms and back, and are really hot. In the same 11 months I haven't changed at all."
"I would call a 35 C a bit of a change." I replied. I was getting hard again, and was trying to maneuver so as to get back inside her. She allowed me to lift her leg nearest mine, trap her other leg between my two, and slip inside her. She was on her back, looking at the ceiling. I was laying on my side, at a right angle to her, and had really good penetration.
"You know what I mean. I work out hard, but nothing changes." She continued, "I sometimes feel like giving it up."
"Jen, what do you want to change? You look great - what's your worry."
"I don't know, I just want to be hot. I want guys to gawk at me."
"Ok, let's think about this." I told her, still plying away at her hot pussy. "You already have a great body. I think a makeover may do the job for you."
"You really think so?" She sounded a bit incredulous. "What's wrong with the way I look now? What's gonna make that much difference. What do you think we should do?"
"For now, I'm gonna finish screwing you, then I think we should do some research at the local bookstore, then go on a small shopping spree." With this said, I was clasping her leg tightly, and starting to really fuck her hard. This position certainly did give me deep access to her. It felt great.
"Oh, that's nice," she moaned as the pace picked up. "God, that's it, fuck the shit out of my tight pussy. Do you like how my tits bounce? God they feel so good - fuck me, Steve, fuck me."
Not one to deny a beautiful woman anything, I fucked her hard for another couple of minutes until I could hold back no longer.
"Take it, that's it take it all, fuck.... FUCK." I pulled out, and sprayed cum up her stomach, leaving long white paths from her ribs down to her closely shaved pussy.
"Do you want to help me with Marisa?" she was still half in a trance.
"What?" I asked, thrown off by this new direction in our conversation.
"You know, Marisa." She answered softly. "Her marriage is on the rocks and she's in a 'hate-all-men' mood. I thought it would be nice if you and I showed her the nice side of men. She just needs a good fuck. I was thinking you and me and her, if you wouldn't mind."
"Geez," she said a few moments later, "Are you hard again?"
"Well what did you expect after throwing an offer like that out on the table. On your knees, please, sort of how you and Marisa might be in your 69, while I work on your pussy."
She giggled but obliged and teased me mercilessly, pretending to be Marisa, telling me how much better I was then her husband, AKA Needle-dick Bug-fucker.
"You know," Jen added, just after I had finished, "Marisa loves anal sex. Of course your schlong may be too much for her, but I bet she'll be willing to give it a try. I'd love to see that. I don't have the courage for it, but maybe seeing Marisa will be the incentive I need. Sometimes I do fantasize about taking you back there. With Marisa's tongue in my pussy, well, who knows..."
My cock, like the phoenix, rose from the ashes, and Jen of course had to pay the price for resurrecting him yet again.

Marisa has been a friend of Jen's since they were kids. I first met Jen when she was about 16; she and Marisa were best of friends even then.
One of the few times I had really been social with Jen was when she was a senior in high school. Cheryl and I were newly married, and we were over at her parents' house around thanksgiving time. I don't recall the exact circumstances, but I was in the house with Jen, Marisa, and another friend of theirs, Linda. The parents were out of town, and Cheryl had gone on some kind of last minute mission of mercy to a friend's house.
If this were a penthouse forum letter, of course I'd soon be fucking each of the three in every room of the house.
What we did do was drink. They were underage, but no one was going to be around, and we were trying an assortment of shots and drinks. We were talking about experiences, and as the old 'wizened' one, I told them about some spring-break experiences (R-rated) and some drinking games and more.
It was probably the most fun and longest talk I had with Jenny until this year. I tried to be a gentleman for the most part, although we did get into some pretty risqué story telling.
Well, enough rambling. The point was Linda passed out and I put her to bed. The game was splitting up and we retired from the kitchen to the living room for a last drink then hit the beds. The girls went to Jen's room upstairs, and I retired to the living room to watch a little TV before sleeping.
