My idea is you notice your stepbrother is looking at your belly after dinner, now that you are done your belly inflates and is sticking out a little, you tease and ask if that’s what he’s into, having a balloon stepsister who inflates. You let him know you can actually inflate if your bellybutton is pressed or blown into and let him try. With each push or puff your belly sticks out even more as you hold your sides and your cheeks puff up as you inflate. After inflating to your maximum size you notice him looking at your bellybutton and inside it trying to see if it is popping to an outtie from being so inflated and decide to let him have a better look and shrink him down and hold your giant belly over him, looking down on him with puffed cheeks. you pick him up and put him into your bellybutton, asking if he can feel your innie bellybutton tightening and popping out, teasing him and letting him play inside, you can tell him if he wants to grow back he will have to masturbate inside your bellybutton, giving him a countdown to cum.
