A group of four drunk students.

Miky, Tom, Sally, and Rosan were best friends. Ever since they'd met, they'd always partied together. This time was no different. The four friends met at Tom and Sally's apartment. The evening was still young, but they were already a little tipsy. Miky glanced at his phone and suddenly an ad popped up. He immediately called the others over, and they watched the ad together until it was over. When it ended, Miky tapped on his phone and was redirected to the app in the App Store. When he asked the others if he should buy the app, they all happily agreed. He bought the app and put his phone down.

The four continued drinking, and the mood improved until, about an hour later, Miky's phone buzzed. He tapped on it and saw that the app was fully installed. He immediately wanted to try it out and asked Tom and Sally to stand together. He scanned them with his camera, and a menu opened for each of them. When he asked what he should change, Tom suggested massively enlarging his penis. Rosan also suggested transforming Sally's mouth and nose into a copy of her vagina. They were all so drunk by this point that no one objected. Miky voice-activated the changes and confirmed them. At first, nothing happened, but then something large suddenly emerged from Tom's pants. He immediately undressed from the waist down, and everyone saw Tom's penis in all its glory. It had now grown to the size of a horse cock.
