You must be feeling lost in a sea of little toys, diapers, wipes, and all that jazz. An adultbaby-induced daze, with all those toys, diapers, wipes, it's like you've stumbled into a miniature world of cuteness and chaos. Your mind is spinning like a hamster on a wheel at the mere idea of your hot stepsister standing before you, armed with a whole arsenal of adultbaby goodies she personally curated and selected...just for you. It's clear that she discovered your dirty little secret. Don't worry, though; she's committed to the idea that you're actually an adultbaby who wears diapers and acts like one, so she won't tell your parents. She has no idea why she keeps picturing you, her stepbrother, in a large adult diaper in her dreams, but the more she does, the more she wants to push one upon you. You're compelled to live by your attractive stepsister's rules, but this could actually work out well for you, as you'll finally get to indulge your secret desire to be treated like a regressed little one by your own hot stepsister. Who better than your favorite stepsister to change your diaper? She reaches for the changing supplies she set out for you, takes out the huge diaper, and reveals her intention to have you wear it as soon as you undress. That means you'll have to put even more trust in your stepsibling than you already do. If your stepsister wants to change your diaper, she will need you to take off your pants, and you shouldn't feel bad if she sees your cock sticking out from under your pants. And then perhaps if you undress, she will muse on how hot she finds it that you are in a diaper, and what if you wear it out as if you have your diaper on underneath your pants, she will touch your butt occasionally, and with the crinkling and wrinkling sound of your diaper fabric, everyone will sure know you are wearing a diaper! Looks like that boner of yours is sticking around for a while! Maybe she can work her magic and change the situation, along with your diaper! Imagining your stepsister wrapping a diaper around you while she lifts your legs and pulls you over so that she can touch your butt and secure the end tapes in place while you stroke your tiny cock would help you relax. If you thought of your stepsister caring for you like a regressed little one and changing your diaper, your cock would probably twitch in an instant! Relax and sit while you think about how clean your butt will be thanks to her. What you really want is for it to leave you feeling clean and refreshed. A sprinkle of powder from your fine little cock is all your stepsister needs to clean up after you. Imagine how amazing it would feel to watch her grab your diaper and then squeeze your cock on purpose, beneath the diaper's cloth. The thought of a clean, new diaper, snugly tucked balls, and a stepsister dousing your butt and balls with baby powder to keep them dry and supple is enough to make you almost jerk off right on. But don't make yourself cum now, because if you do, she'll have no choice but to keep your diaper on with all that slop. A part of her just can't wait to see you in a diaper, all erect and sweaty and desperate for someone to touch your cock. Relax in your freshly changed diaper and enjoy the sense of warmth and coziness as the fabric envelops your buttcheeks and cock in preparation for some cumming. As she touches and squeezes your balls while you're in a diaper, the crinkling sound of the fabric will add to the excitement as she teases you and makes your cock ache. Only if you cum a lot will it leak out from under your diaper; otherwise, it will be absorbed. But it isn't really a problem at all, because she's just in it to stroke your cock on your diaper, rubbing so warmly and gently, teasing you seductively, while you moan so hard until you let out an extreme outburst of cum. And you know what? She's just going to leave you and your dirty little mess down there, because having you trapped under that dirty little diaper with your own cum seems pretty hot for her, surprisingly. Just imagine the wild adventures you'd go on if you ever caved and struck a never-ending deal with your stepsister! You do something for her, and in return, she'll put on a fresh new diaper for you. That would make a good arrangement.
