I'm about 5'8", 165lb. Not a big guy. My wife enjoys large framed men. Her 1st, had a thick cock, with this 'big' mushroom head. The 1st time he spread her lips with that big head, and slowly pushed it in - the gasp she let out. Then, as he got all the way in, he stopped. Watching her - eyes closed, pure pleasure on her face, as she very slowly gyrated her pussy around on his fat cock, that was priceless. We stayed the weekend with him, and we fucked all weekend. Well, mostly they fucked, lol.
Her second 'big guy', wide framed, not fat. Before he got his cock in her, her pussy was way wetter than I'd ever seen before. literally running down her legs. Seeing him between her legs - the were spread as wide as the would go. He entered her, and started going in and out, as he did, she started moaning. He got faster, her moans got louder, and, well, was nothing I'd ever heard come from her mouth before. She was in heaven! He kept up the pounding, for way longer than I thought possible. And she kept up with the low moans.
He finally stopped, rolled off on his back, said breather or something. My wife just hopped up, straddled him, reached around grabbed his cock, and in one fell swoop, impaled herself on it - started riding him like a wild woman.
He fucked her multiple times after that, but never the intensity of the first time. (1st pic, she's guiding the 1st guy in. 2nd pic, 2nd guy has her legs spread 'wide')
