Welcome to Sis Swap - where clever stepbrother or/and clever stepsisters meet up for a swapping session. It isn't always clear whose idea it was but the outcome is always the same - intriguing - awkward at first - foursome where lucky bros get to fuck each other's step sisters. As crazy as it sounds you can say that sisters are no longer a pain in the ass, quite the opposite, they seem to be a perfect currency!
