You're on a trip with your step-sister, mutual friends, and your girlfriend. Everyone in the cabin is resting and your step-sister asks you to come into her room because she's scared. She randomly brings up a childhood memory of when you found step-dads porn magazines and tried to reenact the pictures with your step-sister. Something you had hoped she didn't remember. She explains that she doesn't think the kissing, licking, and touching of each others parts back then counts as In**st. She googles and reads the definition to prove it. But...she wants to do stuff with you again. Even if it is In**st and in the big tee shirt and cute pink panties she keeps flashing, you can't resist your step-sister. Even when your girlfriend starts knocking on the door as your creampie her.
