"Well time for me to change my self, I can't wait to throw the two of you in the trash." Cassie says letting the front of her pulls snap back into place, she head to the change area, fetching her self a fresh pair of pull ups.
Meanwhile Hoshi grinds her hips against Alex's groin, which his cock still impaling her pussy since he basically just froze when Cassie pissed all over them, "Come on Alex keep going," she prods.
"What are you talking about, we need to plan our escape, maybe when she gets changed we can jump out of the nappy while its open, or failing that we should at least be able to wriggle our way out once its wrapped up, but it we take two long then we'll have to climb out of the bin as well." Alex responds trying to plan their escape, Hoshi just giggles at him, "whats so funny?" he demands. Moments later their is a ripping sound as Cassie peals back the strips, opening up the front of her pull ups, and folding it down to pin Alex and Hoshi in place in the very bottom of the soggy pull ups, she answers for Hoshi, "she giggling be cause she knows their no escape, because I'll make sure you don't get out before tossing my soggy pull ups in the trash where you two belong, and well you see unlike at home were we just use a trash can for a diaper pail, they have proper ones here, their call Diaper Champs, and hold about 60 nappies, but the best part is how they work, the bag is sealed by the lid and a rotating bowl is used to dump in new nappies, then when its time to empty the bag dosen't get opened instead the whole lid with the bag lifts up then they twist off the top of the bag to keep sealed before pulling the opening out and tying it off, so once you in the bin that's where you'll stay and the ounces it fill you'll be out with the trash in a tied up bag fill of dirty nappies," she laughs, "wron't that be a fun new home for the two of you to share I'm sure those nappies will have lots of interest stuff in them for you to play with." She resume folding up the soggy pull up folding them in half again the wrapping the stick strip around to form a temporary seal trapping Alex and Hoshi inside the middle of the soggy nappy, "Hows that nice and sung in there," she says as she walks over to the Diaper Champ.
Alex screams "No let me out of here Cassie!", while Hoshi lets out a loud moan, shouting "Yes, your the best Cassie, Bye." as Cassie drops them into the bowl of the Diaper Champ.
"Bye guys, I just pull this leaver and then you become Trash," says Cassie as we pulls the leaver causing Alex and Hoshi to tumble inside her soggy nappy before feeling a moment of weightlessness as they and the used nappy fall in to the pail already over half fill with dirty nappies.
Hoshi rubs her self against Alex again giggling "This is so cool welcome to our new home, your sister is the best Alex, now would you get back to fucking me, I want to come again before we go exploring to she want lovely surprise's the other nappies contain hopefully lost and lots of different type of shit."
Alex glowers at her although she can't see it and givens in resuming his fucking of her as he thinks to him self I hate my sister.
