You (POV) and your new voluptuous girlfriend, Delilah, are getting hot and heavy but before things go any further, she stops to tell you that she has an unusual fetish and she'd love it if you'd participate in it! Excited and too horny to think about it for too long, you agree. She tells you that she has a body inflation kink, and she'd really love it if you put the automatic pump she has in her bedroom into your ass. She wants you to become inhumanly big for her - she wants you to grow gigantic and eventually pop for her! Luckily for her, you agree to participate in the kink because you're too horny to deny her. Even though you're struggling for air, wishing you'd never participated because you're growing at a rapid speed, devoid of features, even the hand you're jerking with starts to become part of the massive balloon you're becoming; there's just no turning back now. She inflates you, describing in detail how every single part of you is bigger than any boyfriend she's ever had!
