"Honey, wake up!" You find your own voice saying to you as you're shaken awake. It was your mom, with your parts waking you up. "Something happened to us!" She cried. "You have my breasts, feet, mouth and pussy!" She grabbed her large breasts on you to emphasize this. 'What, the device was supposed to make her not notice the swaps!' you worry; not noticing the device had hit the ground before, altering it's effects on the swappees.
"What the hell!" you shout. Your mother seems happy to see you awake and helps you to the couch. She asks how this could have happened; you had to come up with something. "I d-don't know." you mutter. "I just felt my body changing when I walked by you." Your mom sighs, not happy to still not have an explanation. While she isn't looking, you try and use the device to swap yourselves back, but it doesn't do anything. Shocked, you come up with an excuse. "I'm heading to my room! I don't want to be seen like this!" You shout and run with the swap remote in hand, or walk since you still wore your mother's sandals. She seems to let you go for now, probably thinking you're more traumatized about this than her.
Now in your room, you strip off your clothes, sans your mother's platform thongs and look in the mirror. What a sight, there you were, a normal teenage guy, with thick lips on your face, large supple breasts on your chest, a shaven moist milf pussy between your legs, and smooth dainty female feet adorned by pretty sandals. "Why? Why was mom aware of the swap and why couldn't I swap us back?" you ponder.
Despite the trauma, you were also curious; you find your right hand beginning to massage your right breast, while your left slips between your legs. A rush of pleasure spreads through you as your fingers go into your mother's honeypot. "That was..." you sigh, before beginning to thrust your fingers in and out. "Oooh" you moan and lay on your bed. You tweak your right nipple with your fingers and suck on the left with your thick lips. This makes your downstairs super wet, much to your joy. Your fingers go in and out of your wet pussy, which grips them in turn. It would seem your mother's pussy hasn't some action in a while and was enjoying your doing this to it.
"I remember something. I said I didn't really want to give mom her parts back before I fell. Could that be a reason why the device didn't work?" you wonder. You kept fingering your mature pussy and began to thrust your hips as well. "Oh god, yes! I do want to keep mom's parts. They're all mine now! They feel so good, she doesn't deserve these!" You say in ecstasy. "What if I was born just to eventually claim the parts that should've always been mine?!" In and out, your fingers go, faster and faster. You curl your dainty toes and finally reach climax, spraying your inner thighs with the love juices of your mom's pussy, or rather, your pussy now. "Definitely keeping us like this. I never want to lose these sexy parts; they're all mine!" you decide. This set in motion a downward spiral you were heading toward.
