Still not entirely believing this app to be real, he decided to perform a real test: on his girlfriend. Ben's mind went wild with the possibilities, his cock pulsing against his shorts as he thought, and then, glancing back at his phone, went to typing:
“Chelsea is six feet, nine inches tall. She has MMM cup”
No. He backspaced over that bra size and typed in “TTT cup size breasts.” Adding “She has a butt so huge she has trouble fitting through most doors. She loves being enormous and fantasizes about being even bigger.”
He hit the Execute button, which went off with a “ding” noise. Minutes passed, and Ben was about to chalk it up to “way too good to possibly be true” until he noticed the photo of himself and Chelsea by his monitor had changed—where once he was wrapping his arm around a shorter, rather waifish girl, it was now a photo of himself being pressed into an huge left tit bigger than his own head, a blue tank tank top barely containing said boob—Chelsea's head and waist were completely out of frame.
His phone then dinged with a new text, from his girlfriend.
“Hey, hon?” She didn't wait before texting more. “How about I just come over to your place and we just stay in?”
A crude self-taken picture of her ass came in next, followed by, “My fat butt needs your face!”
Ben tried to begin texting back, but was interrupted by a cleavage-pic, and then a text of “My gimungous udders need sucking again!” And then another message, which was simply “Moo?”
Finally, Ben was able to respond with a simple “Sure!”.
It wasn't long before he heard an increasingly louder thumping of heavy steps drawing closer to his door, and then a loud, almost obnoxious, knocking. He opened it, and immediately had to take several steps back as giant Chelsea ducked down to fit through, and giggled a little as her loveseat-sized ass momentarily became stuck in the frame—she was wearing a far-too-small black tank-top, her chubby belly spilling out from below—a pair of denim shorts similarly struggling to contain those thick thighs.
He then felt hands slide under his armpits, and lift him upwards—his entire chest soon squished suffocatingly against Chelsea's massive boobs. “Hey, sexy boy!” she rumbled—even her voice was deeper, now, bigger. Along with all of the rest of her. His face was then pressed against a huge pair of eager lips, the giantess Chelsea's tongue flooding into his mouth as she kissed him sloppily, only putting him back down after an almost painful squeeze to his butt.
The two snuggled up on his bed, watching random movies for a bit as Ben alternated between massaging his giant girlfriend's breasts, and her butt, before the topic of her size came up....and how she wanted to be yet bigger...he wasn't able to resist using the app to grant her wish, which was...
A. To be a 100 foot tall woman. Watching Chelsea-zilla go to town sounded just TOO hot....
B. To have outrageously massive muscles.
C. To be a hyper-horny, shameless bimbo!
