Prison Skiing
the homosexual act of dual, simultaneous hand jobs, as performed during a prison threesome by the beta inmate, as he is pleasuring two alpha inmates. Only, instead of ski poles, the said beta has a dick in each hand. Probably in his mouth, too.
Most nights in Parchman, Matt closed his eyes, and pretended he was competing in the Alpine Men's slalom competition, as this was the only time in custody that he felt like he was "winning." See, prison skiing was the only thing that would keep Dante and Tyrone from turning Matt's asshole into truffle butter.
