You broke your bed having sex, so our mum has said we should share a bed until your new one arrives. We are far too old for this, aren't we? I don't know what to do with you here, you're really distracting. Maybe we can play a game? Like... truth or dare? The truths get more personal, and the dares naughtier as the game progresses. Clothes come off, hands end up in places they probably shouldn't, one thing leads to another, and your cock ends up in your sister... I wonder if mum knew this would happen?
