We are having sex, and I make one wish. I wish for my belly to expand during sex. I talk about how good it would feel for both of us to watch my body expand. Each time you cum inside of me, my breasts and belly begin to expand. They get bigger and bigger as the video goes on, until I have to lay on my back and let you keep going.
Your last cum shot ends up all over my inflated belly and chest.
*Includes expansion talk, no nudity except for in the very beginning.
