(This was originally filmed as a custom video, and this version has subtitles for the imagined speaking parts. There is also a version without subtitles available in my store) Waking up one morning, you realise you're in your sister's room... No, wait... You're in your sister's body!? You can't believe what's happening, and feel the need to prove to yourself that this isn't a dream, but having a good and thorough investigation of your new body... Unfortunately, just as you really getting acquainted with your new apparatus, you're interrupted - by your sister barging in, piloting your body! She's furious to see what you're getting up to with her private bits, and accuses you of being a massive pervert. You protest that surely she did exactly the same when she woke up in your body - she can't honestly not have noticed the massive cock and swollen balls now dangling between her legs? You convince her to get your(her?) cock out and investigate, encouraging her to take it for a spin and jerk it off. She seems to enjoy this, in fact maybe a little too much... As she soon gets the idea that she wants to try putting her newfound cock into her pussy! She doesn't seem to mind that in fact you're currently in possession of her pussy; she insists she try out her new gear properly! You try to warn her about how very fucked up it would be to do what she's thinking, but your sister ignores you and slips your/her cock into her/your pussy! You're instantly overtaken by this crazy new sensation and can only protest weakly as your sister gathers steam and begins pounding away at you. Though your mind is being completely blown by experiencing being fucked by your own cock, it doesn't keep you from having a huge orgasm with your new pussy! Your sister is jealous and wants it to be her turn to cum, and you frantically remind her that it would be a terrible idea to cum inside her pussy and get herself pregnant! You offer her a pair of her panties to cum into, saying that you've cum in them plenty of times before (at which she's briefly outraged, before continuing to pound you), but instead she chooses to empty her/your balls all over your/her face, shooting a huge load that leaves you horrified yet impressed!
