"Get ready, I'm going to cum!"
From Create Your Own Story
She doesn't say anything, probably because she doesn't know what cum is, but you pull her body close to yours as you feel a powerful orgasm well up in your balls. You try to tell her your cumming, but instead all that comes out are gasps and moans during the excruciating moments before you finally blow your huge load. You hold her so tightly you probably leave marks but you don't care, you just keep shooting rope after rope of hot cum onto yourself and her. After what seems like an eternity you finally finish cumming, and you release your sister and slump to the bed in exhaustion.
Your sister scoops up her clothes, wipes herself off with the towel on your floor, and races out the door.
What do you do?
