It turns out your mother just at a ton of food. You can't take your eyes off that large belly of hers.
"Does this interest you?" she asked.
You blush.
"It's okay. I don't mind." your mother responds, "Why don't you come over here and rub my belly."
You do as she says and start rubbing her belly. She starts moaning, enjoying the feeling. It starts to make you uncomfortable and you begin to sweat. Eventually she tells you to stop and then she looks at you, with a weird grin on her face.
