Up The Stakes

Steve (Elias Cash), his girlfriend Cassie (Leana Lovings), and their mutual friend Danny (Victor Ray) are playing poker. When Cassie takes a break and goes into the kitchen to make snacks, Danny suggests a wild bet: whoever loses the next hand gets to fuck the other guy's girlfriend. Steve playfully accepts, not thinking the bet is serious. But when he loses, he finds out that Danny was completely serious about it.
When Cassie finds out about the stakes of the bet, she seems furious and decides to go along with it to make Steve feel bad for using her in a bet. Steve eventually leaves, dejected and humiliated, but once he's gone... the truth reveals itself.
