You are napping and your sis is trying to wake you up, you tell her to go away when you realize your voice sounds so high pitched and feminine. WTF you wake up fully and see yourself standing before your very eyes.. WTF is going on? Sis? Why are we?You are disgusted and horrified to be in a womans body, being a bit of a misogynist, being a woman is the worst thing in the world! It makes it even worse the woman is your sister! You accuse her of putting this spell on you and demand she reverses it. She tells you that she received a letter saying the only way to reverse the swap is to fuck EVERY DAY for 1 month. You tell her there is no way you are fucking her once, never mind one month. But it begins to dawn on you that otherwise you'll be stuck in your stupid whore sisters body for eternity if you dont.. You LOVE being a man. And will do anything to get back to your masculine body. You reluctantly agree to fuck, but only in missionary and ONLY the tip. You lie on your back and your sis inserts her, or your, dick in. The tip hurts you so much, you knew your dick was big but now you were on the receiving end of it, you wished it wasnt so big! Your sis fucks you with the tip of your cock, as you pull faces and moan and whine about having to do this. You notice your sis looks like shes.. enjoying it?? WTF. She is enjoying dominating you and seeing you like this .. so submissive.. so weak.. on my back like some dumb whore. You tell her off and tell her she will be sorry once your back in your body. You tell her to hurry up and cum but she says she can't with only the tip. So you reluctantly agree to the whole shaft. OUCH. That hurts! Its so big! This is so humiliating! You cant believe your getting fucked and dominated like a woman... by your own sis.. You tell her to hurry up and cum, but tell her she better not cum inside. But just to add to the humiliation: She explodes inside of you and your left feeling degraded and disgusted with a big load of your cum seeping out of you!. 1 day down. 29 days to go..
