It's May, everyone!
You are Brendan. You are crushing on your busty rival, May, and she's driving you nuts. One day you finally manage to defeat her.
You demand her bike pump and that she turn around and lower her shorts. Thinking you're about to >rape her she tries to talk you out of it. Instead you insert the tube into her anus and begin pumping.
She turns to you and complains about the bloat but she takes it like a champ considering how you're not raping her. Perversely, she's starting to enjoy the pain of getting her belly pumped up like a balloon. Soon enough your bloated babe realizes if you continue she'll burst.
(You can mention that you have done this to a couple female Gardevoir's and Milotic's in the past and busted them.)
Needlessly to say after surprassing the size of a pregnant woman she pops and her overinflated intestines spill onto the ground. Grotesquely she has come. Hard.
