You barge into your big sister's room and find her in her punk vest and cheeky panties, tits all hangin' out. You're shocked because you've never seen her like this before. She sees how lost you are and decides to teach you a thing or 2, so she has you pull out your cock and gets to work on showing you how good a girl can make you feel. You cum all over her tits after a nice old fashioned and she makes you promise to keep it a secret
