frosty thrust

It invloves three people when riding a chairlift and someone's clothes are ripped off and someone's penis is shoved up another's ass. The one receiving rides down the hill, still penetrated and shits up the urethra of the one delivering. The third comes flying down the hill, wanking off, and upon contact, thrusts into the fucking mass ejactulates and they tumble down in a mess of shit, jizz, and snow.

Becky, Ryan, and Eric wanted to perform a frosty thrust on the mountain.
