She jumped up and grabbed his arm. As they both left the cafeteria, she could hear some of her friends laughing at the boys...Or maybe at her. It didn't matter, she really couldn't focus on that right now.
As they moved down the hallway, she could feel her sex spreading open as the breast pushed out. Her upper breasts shrank until she could hardly feel them rubbing the fabric of the shirt.
He asked, slightly panicked, “What’s wrong? What are you doing.”
“Can’t explain... Just come on...” She replied as they rounded the corner and went straight for the handicap bathroom.
Luckily, nobody had followed them and the hallway was empty when she pulled open the door and pushed him in.
Once inside she locked the door and yelled, “I need you to fuck me right now!”
“I... What? Are you serious?” He asked, looking very confused.
The poor guy. This may very well have been his first time for all she knew, but her wet vagina and the tender breast in her groin were desperate for attention.
“OK... But don’t tell anyone, this is strange enough...”He replied.
“That a boy,” she thought, grateful for the cooperation. She quickly pulled down her skirt, revealing the massive tit. Her labia spread wide and the opening had extended several more inches up her mons to accommodate the breast’s most recent expansion. She started massaging it with one hand while fumbling to remove her shirt with the other.
“What are you waiting for?” She asked, as Brian stood there wide eyed.
“Oh, right...” He said, then started to pull off his shirt.
After a moment he was nude. His cock was hard and looked to be seven, maybe eight inches long.
“Not Bad...” She thought as she moved towards him.
It didn't take long for her to find out that her breast made it difficult to fuck from the front, so she turned around and leaned on the sink. She felt his cock rub along the bottom of her sagging C cup breast as it slid into her moist hole. As he thrust in and out she fondled her nipple, which was already oozing milk. For some reason Brian didn't seem phased at all by this and continued to fuck her.
It wasn't long until the bell rang.
“Shit!” She thought at the sound echoed down the hallway. She was still aroused. The swollen mammary gland in her crotch continued to ooze and she began to orgasm. This was more growth and arousal in one setting than she’d ever experienced.
“I’m about to cum!” Brian said, pulling out of her cunt with a quiet slurping sound.
He aimed at the toilet bowl and let it fly. Watching him lose his seed added to her arousal as she continued to stroke and squeeze milk out onto the floor.
Still looking a bit dazed, he said “I've got to go... I’m gonna be late for class...”
“OK... Thank you...” She replied between breaths. She wouldn't follow him out. She really couldn't. She was still too aroused to do much more than stroke her malformed genitals.
On shaky legs, she managed to lock the door behind him, then continued to masturbate. She had several more orgasms and after nearly an hour had passed, someone knocked on the door...
