Sister Always Wins

You're my brother and you try to make multiple bets with me. i do each bet to prove that i wont lose to you. each time we almost get caught by our other sibling so we try to be sneaky. once i win all the bets you cant accept defeat so you bet that i cant make you cum. i give you a bj and thats not working so i decide to fuck you (doggy) i make you cream pie my pussy but we get caught by mom!
