Your step sister heard you watching porn last night. In fact, she hears you every night, and it's been keeping her awake. If you don't stop, she's going to tell your Step-Dad. She knows how pathetic you are, and she wants to know what she has to do to get her rest at night. If she helps you out now, would you stop jerking off every night to porn? How about if she helps you?You love her big tits, so she offers to show them to you. She opens your zipper and pulls out your cock and begins to stroke you. She's pleased with how big your cock is, and keeps stroking it. Sliding it between her big brown tits makes you almost cum right away! She keeps working your cock until you spray a huge load of cum all over her beautiful breasts.
