Not sure if this goes here but there is a story that does involve a girl inflating a guy.
Max lays on the ground as he feels the cold liquid of whipped cream entering inside him.
Feeling helpless, all he can do is accept his situation and let the cream enter inside him as his belly expands.
With each movement his belly wobbles and jiggles, sending a shock of sensation throughout his body. He rubs his swollen, gigantic belly and lets out a sigh of pleasure when he gently presses his belly downward.
"Mmm-uhhh... *pants heavily* I hope Suki turns the tank switch off before I---Uuuugghhh..."
Max lets out a moan of pleasure as he feels the whipped creams slowly oozing out of him from every orifices.
