Ivy has gained so much weight that when she goes on vacation, she has to rent a scooter, otherwise she can’t leave her hotel room. She’s too big for the scooter, and thinks about how fat she must look riding around town. She hopes to be able to buy her own scooter someday, because she’s just too big to walk long distances. Being so big and immobile turns her on so much. She struggles to masturbate because her belly is so big and in the way.
