[QUOTE="Apostate, post: 422111, member: 23501her face looks a lot like that of one of my long-ago girlfriends. She really did bare her teeth like this when she came.[/QUOTE]
THE reason this topic attracts me is that my wife bears her teeth in a clenched way whenever I am inside of her AND her legs are bent at the knees while I'm on top of her and she is spread. I guess I've written about this before, and how much it turns me on.
In our two MMFFs we had before we were married, one was with a couple we had known for a couple of years, who we occasionally saw at parties in Las Vegas and the crowd I would hang around with when I was a student at UNLV. Over time, this couple and my wife (gf then) got to enjoy one another's company, and neither of us were anywhere into dedicated adult play. But we suggested their coming to our room and we got drunk and I asked them, for my wife and I, if they would like to play with our hands and our mouths. They nearly immediately smiled about it. I thought we would begin with SOME kind of preliminary fool around with your own partner, but he simply moved in on my girlfriend and they began French kissing like they'd always wanted to do that. Ironically, I was the one who knew of them from back in the day, and my girl only knew them from about 3 party events. Me and his girl may have wanted one another over time, but probably to say to ourselves, "F*** yeah - We finally got to know everything about one another as a lover." My girl and her guy acted as though they had been in two cages for a year, looking at one another every day and panting over the idea of being together. Though I always thought of the event as soft, in about 20 minutes he was inside of her. His girl and me had a great time together, but admittedly not as much as the other two were having. His girl and I were in the next bed and we did spend most of our time interested in one another, but ultimately she looked at her boyfriend and my girl and said words like, "Fuck, he's pile-driving her! I had not idea! He never mentioned he ever thought about Gina but just look at her teeth!"
