Input: Text: i play a lot of coed volleyball, and i was playing a pickup game with a bunch of people, most of whom i didn't know. there was one guy, though, who i know and sort of have a lady boner for (just fyi, guys who are good at volleyball are hot regardless of what they look like). anyway, i was setting for this guy, and we hooked up on this really amazing play where i set it like perfectly and he hit it straight down right through the seam in the block and it was like an orgasm worthy play. so i stuck my hand out behind my back to give him a low five, and kind of walked backwards towards him holding my hand out (i was watching the person who was serving the ball, which is why i didn't turn around to give him five). i made contact after a couple seconds, and when my fingers touched down they reacted involuntarily and curled inward, like they do every time i give someone five.

but when i curled my fingers, i realized i was not making contact with his hand, but was actually gently cupping his balls. and since he was wearing basketball shorts, there was very little between my hand and his sack. and instead of moving my hand like a normal person, i kind of gave his nuts a little shake, still sort of thinking i was giving him five. i was in shock, i guess. i finally snatched my hand away and turned around, eyes wide, mouth open, cheeks on fire. i wanted to die. but he just looked at me, winked, and whispered, "it's ok, i liked it," then walked back over to his position.
