He's not waking up in the same body...

After reading the description of what this app could really do, you grin. You suddenly remember that if he fell asleep masturbating, there was probably still porn open on his computer. You go over to his computer, and end up frustrated after the 5th attempt guessing his password. Just when you're about to give up, you notice a sticky note with the words "Password reminder: BOOBS" written on it. You try to input every synonym and slang you could think of such as tits, bazongas, and even more outrageous ones before it hits you. 80085. BOOBS. You reason that the letters were written in capital letters for a reason, and it was proven correct when the profile booted up.

You were greeted by a porn hub tab, unsurprisingly, and it had a tag line of "Ripped Jock Tears Apart Shy Hottie with Massive Cock." Wow... His tastes disgusted you more than expected they would, but it solidified your initial plan. You pulled up the mannequin on the app and started to make it more and more similar to the girl onscreen, including some of your own preference, naturally. Time flies by as you customize him in the app.

45 minutes later...

'Perfect,' you think to yourself. You hit the [Save Changes] box, and step back to watch the soundly snoring man's body change. His loose football Jersey firstly started to rise up with the new additions growing into his chest. You watch as the hem at the bottom starts to ride up, revealing disappearing abs and a narrowing waist line. As his chest ballooned out, causing his jersey to stretch horizontally across his widening chest, you find yourself getting a little turned on by his feminizing form. His arms thin out, and he starts unconsciously groping one of his boobs, as butt and thighs lose some definition and thicken upstarting to cradle his balls and squeeze his shaft. As they thicken, the shorts he was wearing become skin tight, before partially splitting at the bottom seam on either side, allowing triangles of creamy thigh flesh to ooze out from underneath. By now, his midriff was completely showing, as his new watermelon tits showed off ample underboob, and started to stretch the neckline showing cleavage. You become aware that you've completely soaked your panties as you watch him stick an arm into his cleavage from above and start kneading one of the nipples so prominently showing through the stretched holes of the jersey, while his shrinking hand pumps his dick slowly, and then his dick orgasms its last, leaving sperm covering his underboob. You are currently sticking three fingers up your own wet pussy watching the spectacle as his dick shrinks way leaving only a prominent cameltoe behind through the beyond skin tight athletic shorts, and you also reach an earth shattering orgasm, spraying the hard wood of his basement bedroom/man cave. You giggle a bit realizing that man cave isn't an adequate title for it anymore anymore. His hand wanders further into his pants, only to awaken with a shriek from his now mature face upon the completely foreign object entering a foreign orifice.

He looks at you with confusion and fear, his breasts jiggling wildly as he backs away falling over the back of the couch. He stands up and keeps backing away up to the wall, the frenzied jiggling from his fast movement causing the Jersey to stretch it's last, as it tears up the front with a RRRRRRIIIIIIIIIIIIIPPPPPPPPP!!!!!!!!!!

Titties flopping in every direction, you can only stare in lust, unsure if you can hold yourself back. You stare with a predatory grin at the confused, newly minted woman. "You've got terrible taste in porn, but great taste in women, step-bro... Or should I call you step-sis?"
