Your sister notices you come into her room and is obviously creeped out. You say you want to play a game of truth or dare and she agrees after some discussion. It gets quickly flirty as she has you admit to never having been with a girl before and that you think she, your own sister, is hot. She eventually dares you to take off your pants and you dare her to give you jerk off instructions. She agrees, and teases her hot tight little body while doing so. At the end, she finishes you with one final dare, to eat your own cum. Enjoy
