Sisters Rapture and Lilly Ice have always been close; maybe a little too close. While hanging out on the bed, they decide to challenge each other to another arm wrestling contest. The loser of the last challenge had to let the winner kiss them, but the stakes are higher this time. After each loss, 1 of the sisters must remove a piece of clothing. Before long, both girls are stripped down to their thongs, and agree to 1 final fall, with the winner being able to do whatever they want to the loser. Lilly wins, and to Rapture’s surprise, tells Rapture she wants to suck on her tits. Rapture has no interest, but she lost, and allows Lilly to have her way with those DD tits.
