What was your most surprising or unexpected sexual experience?

In college, I worked in the campus cafeteria. I had a coworker who was the friendliest, goofiest nerd. He always had a silly, boyish smile plastered on his face, a mop of shaggy blonde hair on top. He was really kind to everyone, nonthreatening, and fairly dorky, and lowkey really cute.

Our friendly banter developed into playful flirting, and although he wasn't typically my type, I invited him over to "study" (because getting laid before a big test always helped me!) I wasn't sure his sexual experience level, and I was expecting a night of giggling, nervous kisses, maybe I'd rock this innocent guy's world.

Boy was I wrong.

Once he realized I was down for rougher stuff, he was on me like an animal. For the first time ever, his goofy smile disappeared. His eyes went dark, his hand around my throat, fingers inside me, his voice a low growl whenever he spoke. He turned me into an whimpering puddle.

Part of what was so hot was that this was a completely different man in my bed, like a switch flipped. I thought he was an innocent, childish, possibly meek guy who couldn't hurt a fly, but there he was, slapping and biting me, completely in control.

That was ten years ago and we only hooked up that once (I think?), and perhaps my memory has embellished the experience... but every now and again, he pops up in my thoughts, and I can see his darkly passionate eyes and intense face, how shocked I was, how amazing it was.

Whew, I've got to go take a cold shower now.
