I used to write stories as fbbfantasy (check link in profile), which were sorta loosely based on reality. I've had the luck of dating several women in the past who either lift weights regularly, or will play up what they have in a domination sense.
Current GF though takes the cake.
She exercises often, if she had her way she'd go 7x a week, and see a personal trainer 2-3 of those times. She's 5'7" about 140# and is at the point now where she can squat a plate on either side, deadlift 2 plates, lat pulldown half her bodyweight, etc. And is genetically blessed with huge boobs. Despite being in great shape, she was initially weirded out by the fact that I think muscle on women is really attractive.
But she's coming around:
About a week ago I was talking about some FBB casually, and she replies with "well knock it off, because I'll flex for you anytime you want."
Sex this past weekend, ends with "I'm flexing for you honey, look at me and finish up."
We were at the gym on Sunday, and there was a srs FBB there, almost looked pro, I didn't recognize her but she was god damned jacked. Later that night, my GF asks me if I find that attractive. I reply by saying on a day to day basis, not sure, but on a 'I want to rub all of you b/c it'll make me crazy' once basis, hell yes. I then assuage her by saying that she doesn't really need to get any larger, there's very little about her that could change or get stronger, b/c she's pretty strong as it is. Her reply "well, you said there weren't many things, so what are the things that could be stronger?" And it was a genuine question.
I know I'm not the only one here who's got a situation like this. Share stories.
