No chance in hell (transformation)

John, a college freshman, really liked Jane a girl a year above, blonde, smart, with a huge rack. But when he asked her out, he discovered how bad her temper was.

"Do you really think I would go out with a guy like you? I don't do charity, loser!"

Shocked and depressed, John walked away and as he wandered aimlessly heart broken, he found himself in front of a store called Spell'r us. He decided to take a look inside, curious of what they had to offer. But inside there was a lot of strange esoteric stuffs that he didn't understand for the majority. About to leave, he's stopped by the cashier.

"Broken heart, uh?"

"How did you know?" John asked.

"You're here, and you don't look like you're in a good place. So, let me give you this."

The cashier take a pink bottle and put it on the counter.

"Sorry, but I don't intent to buy anything." John said.

"Then, it's free."

The student sigh, the cashier knows how to work with clients. "Ok, how does it work?"

"Put a good quantity on her skin, and she won't be able to resist you."

"Just that?" John said sarcastically.

"Don't be mad at the player, be mad at the magic, I don't do the rules."

Still, he picked the potion, not really convinced. Putting the liquid on her skin would be quite a challenge. He could throw it at her, but if it doesn't work, he could be prosecuted for ****. Instead of that, he found her soap bottle in the showers of the dorm and put the potion in it.

Jane arrived later and used the soap, which felt strangely good on her skin.

"Wow, why does it feel so good suddenly? OooOooh..."

She used more and more of it, emptying the bottle in one shower.

The pleasure become unbearable, and she can't contain herself, cumming in the shower. It was a bit humiliating doing it in the shared shower, but luckily she was alone.

Back to her dorm room, Jane laid on the bed and slowly dozed off until she felt asleep.

John heard something behind him as he was studying and discovered Jane without her limbs and three times smaller. Taking her in his hand she seems half conscious, constantly moaning.

"What the fuck! I thought he meant unable to resist my charm, not unable to resist... Damn it, that's what he meant."

Then Jane pushed a long moan, clearly feeling an orgasm and her body start to shine, while the bottom of her body turns pink and her pussy grow.

"She's turning into a sex toy..." John said to himself. "Well, suits her well, that bitch..."

The more she cums, the less noise she makes, and the more her body turns into silicon.

"Well, better use her, now she's like this. I don't think I would have liked dating her anyway..."

John then pushes his cock into her silicon body and fucks her. It's tight and full of bumps for better sensations, not knowing that she feels his cock going all the way up in her body. Her mouth and pussy linked by a long tube, she feels his cum filling her and overflow out of her mouth. She can't even be angry, she only feel pleasure as he use her like a sex toy.

Having cum enough, John left her on the floor drooling cum from both openings.

While he is gone to Spell'r us to find a counter potion, Jane is waiting on the floor, eager to get fucked more. Luckily for her, his roommate who was supposed to be with his family came back early and found her.

"Dammit John! This is disgusting!"

He cleans her under the water and leave the dorm room with the sex toy in his pocket. His friends will probably have a lot of fun with it.
