An app called Omni Hypno Plus

"Look at this," your friend Dennis said with a wide smile on his face. "I tried the 'Circe's punishment' default in the Omni Hypno Plus app, and look at the dorks," He said and gestured in front of him at the students grunting and squealing on the floor.

"Wow," you say at the sight of some of your bullies skittering across the floor after a loaf of bread Dennis just tossed. Brad the Chad was stuffing his mouth and wiggling his butt in the air. a corkscrew tail popping out of a hole in his shorts, his arms and legs shrinking into cute stubby legs with cloved toes.

"Pwease Dennis, oink," Diana, a cheerleader bully said, tears in her eyes as her ears migrated upwards to the top of her blonde twin-tailed head, her nose growing into a flat snout. "Oink-Oin-I don't want to be a sow." She said, sitting on her butt and pawing at Dennis' leg, her limbs growing short and stump as new rows of leaky tits began growing down her chest and torso, milk beginning to leak through her cotton top.

"But you're such a cute little sow, DeeDee," Dennis said as he was absentmindedly tapping at his phone. "Or should we call you DozenDee now," he added with a small laugh as she seemed to notice for the first time she had grown more breasts.

Three piglets with the clothes of Janice, Chad and Sarah had noticed as well. They ran over and made Diana fall over. They used their snouts to reveal her pink milky tits and latched on to the juiciest ones they could get their mouths on. Diana squealed for a moment at their aggressive biting of her nipples, but pleasure seemed to overtake her as she gave in, rolled over and let them suck her dry. Her curly tail lazily wagging beneath her skirt.

"She's still in there," Dennis said to you. "I modified the settings so that she'd think she is a human turned into a sow, while the rest just think they're pigs in human clothing."

"So it's an hypnotizing app?" you asked in a disbelieving tone, glancing down at the half dozen pigs eating slop or Diana's breast milk. "That works?"

"I know, right?" Dennis said, tapping away before a buzzing sound came from his phone for a second or so. "Well, it says it's an 'Hypno Plus' app, no idea what the plus stands for. Anyway, you can do all sorts of stuff. Most of these things take some time though, but once you're exposed there's no turning back unless you counter-program. If you are to use it on someone other than yourself you have to do it through sound, or a live picture."

"Like that sound you just played?" you ask as you step back momentarily. "Wait, did you hypnotize me just then?"

"Maybe?" Dennis said as he gives you a guilty look. "Anyway, it will be a few minutes before you'll notice anything, and it wasn't a primarily mental hypnosis."

"Not a mental hypnosis?" you say with incredulity in your voice, crossing your arms. "That's like saying 'here´s some dry water for you.'"

"Call it **** hypnosis then, or an hallucination," Dennis said while working on his phone. "You trick your brain into hallucinating something, keeping you lucid."

"Oh, that sort of makes sense," you say as you glance over at the pigs in clothing in the classroom. "But... they are looking like pigs to me."

"Yeah, I haven't really figured out that part yet," Dennis admitted. "That was one of the things I was trying to test out with that beep a minute ago. I just did a scan, no pig hypnotism on any of us right now."

"That's good to know... but what did you write," you say as you give Dennis a look and blink your eyes rapidly.
