Friends from long ago are reunited by accident. Friendship nit renewed but instead money exchanges hands. 1 friend rich, the other kinda poor. Rich guy buys poor friend as a “steed” to fight, where it’s win or be humiliated by other guys fucking him.

Guy gets robbed by boyfriend then boyfriend disappears. Gets on train to go anywhere, winds up climbing a mountain n encounters a mean looking climber, who earns then saves him. They have to camp the night n they have sex. Turns out mean climber is a cop in a small town and guy was a 1 night stand. Guy tries n tries to build a relationship. Really good.
