"Sweetie, I think we should discuss what we should...." Your mother says, barging into your room; she sees your fingers plunged deep into her wet pussy. "What in the hell are you doing, young man?!" She demands an explanation with such anger in her tone. "Uh, ok, this is exactly what it looks like. I can't spin what you see any other way." You sigh, standing up and stumbling from the post session sensations. Still rather furious, your mother leaves the room after informing you she will be back later after you both have thought things over. There wasn't much for you to think though, since you know exactly how the swaps occurred in the first place as well as the fact the device won't swap you two back.
About an hour later, your mother, seemingly calmed down yet still pissed, begins to ask what you know of this. She appears to have gained some suspicion for you. "Ok! I might as well tell you; I went to this store where magic stuff was sold and bought this nifty device that let's people swap body parts. I used it on you while you napped and took the parts of yours on me now." You explain, groping her large tits on your chest. Surprised, she hastily speaks an idea, "Let's just swap back then, so we can go back to normal and forget all of this!" "Yeeaaaah, I tried that earlier and the device didn't work. For some reason, we're stuck like this." You murmur, looking away from your mother's eyes.
"So, you're stuck with my intimate parts? Fine then, enjoy them." She says with a smile. "Wait, what?!" You shout, not expecting her to say that. "You can keep them if you want them so badly. I guess it's better for my son to have stolen those parts instead of someone else." Your mother tells you. Completely shocked, you watch as she leaves the room, somewhat depressed. "She can't be serious; I have the parts that made her a woman, and she's ok with it?!" Looking down, you wiggle your dainty toes in the platform thongs and smile. "Works for me; now I don't have to feel guilty about keeping these babies." You smirk, rubbing your breasts and crotch again.
