I know how much you have been hanging around in my room always trying to catch me in my skimpy nightgowns, always bringing me snacks. And after you left the other night I heard you jerking off in your room, and I KNOW you were thinking about my big fat body, and now... I need to see for myself... So pull out that cock and stroke it for your big sister, while you watch me jiggle my huge belly and rub my tits for you.... But remember you can't cum until I say so.. Let me count you down in 10. 9. 8. 7....
