Your girlfriend just broke up with you and you tell your sister the story. She believes you deserved it of course since you left your girlfriend high and dry at the movies, but sympathizes anyway. You tell her that your girlfriend said that you had a small dick and that girls always tend to say it when they break up with you. Your sister teases you about it and eventually says she'll judge for herself, sooo you show her your dick and she quickly swallows her words! You definitely DO NOT have a tiny dick and just the sight of it turns your sister into a cock-hungry slut! She seems to forget that attached to the massive cock is her very own brother and plays with it like it's her favourite new toy!
