Cassie grabs her self a pair of fresh pull ups, and pulls them half way up her thighs so they form a tight seal against the leg opening on the fresh pair of pull ups, she care fully adjusts the leak tabs to ensure nothing can escape them, before ripping open the strips holding her current soggy pair together and allowing the back to fall in to the fresh pair of pull ups causing Alex and Hoshi to fall into the fresh pair, she carefully shakes the soggy one as she lifts them up to ensure Alex and Hoshi can't hold on placing the soggy pair on the table she quickly pulls up the the fresh pair pressing Alex and Hoshi tightly against her crotch. Hoshi giggle "Well guess she has more fun planned for us before we get to become diaper trash."
"Stop acting like this is a good thing you sicko" cries Alex.
"But it is by the end of the day I'm sure we're going to be permanent diaper trash sealed up in a bag full of well used dirty nappies and I'm have you to keep me well fucked, what more could a girl ask for. And then what ever games Cassie has for us in the mean time are sure to be fun too." she moans rubbing her breast against his face.
Alex given in after a failed attempt to escape Cassie's pull ups, and pulls Hoshi face down pressing it into his groin as he forces her to suck his cock, and causing her to moan uncontrollably as his cock pound in and out of her mouth until he shots streams of cum out filling up her mouth as she happily swallows his gift.
Hoshi manages to turn herself around with his cock still semi erect in her mouth so that her legs fall open around his head giving him free access to her pussy, which Alex happy takes to suck enjoying the taste of her juices.
After several hours of play Cassie opens the front of her pull ups again and says "Hi guys good to see you enjoying each other, guess what Hoshi, I just noticed one of the pottys is empty, we all finished snack time while ago though so that will change soon. I'm going to drop both of you in one so you can get the aftermath of snack time". Hoshi moans out an eager "Oh, Yes please Cassie, such a wonderful idea", while Alex cries out "No Cassie don't do this, I'm your brother."
"Yeah well I never really liked you Alex, and just look a Hoshi shes basically coming at the idea of getting buried in the potty. So I'm afraid that your going in." Cassie says as she grabs both of them from her nappy. She walks over to the potty and lifts the lid before dropping them in it. "I hope you get a nice big mess!" she says, giving Hoshi and Alex a smile before dropping the lid.
Now in complete darkness, Hoshi feels around for Alex, quickly grabbing him and pulling him close so she can be rubbing his cock. "We need to get out of here!" Alex says "There must be some way to escape, if only we can get the lid up"
"No there's not, we cant climb the walls, this is going to be filled with us in it! we're gonna be potty trash!" Hoshi begins singing about potty trash for a minute.
With that there is a loud sound and a blinding light as the lid is lifted. They look up to see a 3 year old boy fidgeting with his pants before pushing them down and sitting on the potty.
"Oh no! We need to get out now!!" Alex says. "Hey hold it!" He yells out hoping the boy will hear him, but the only response he gets is a loud wet fart. "Oh yes! you can do it! Give us everything you have!" Hoshi excitedly yells as she gets on her knees and starts sucking on Alex's cock.
