Colorado bear trap
When a twink is sitting on a Bears (large hairy gay man) dick and right before the bear cums he wraps his legs around the twink and cums into the twinks ass.
I thought my uncle and I were wrestling, but then the next thing I knew he caught me in a Colorado Bear Trap!
Colorado Bear-trap
The Colorado Bear-trap is when your fucking a girl and right as your about to bust a nut, spread her asshole apart, drop your dick down into it and let it rip. When you pull it out her asshole will clamp shut and thus, the trap is set.
I gave Cindy a Colorado Bear-trap last night, she loved it.
