Being useful (dildofication)

"I don't have time for this, sorry, I'll take care of that later. Promise."

"You never kept your promises, it's been weeks that you skip your part of the shores and I have to do everything !"

"Cut the crap ! I always keep my promises ! Stop bringing everything to you, I'm the one who do everything here !"

"Tell me one thing you did lately !"

"I told you I don't have time ! You're such a cry baby !"

Sarah left, slamming the door of the apartment and leaving Jane alone. The later was sick of her lazy roommate who would find any excuse to do shit. And since she kept being a useless bitch despite her constant calls, she had come to a decision. She'll make her roommate useful.

So when Sarah came back home, Jane used her magic on her. The black haired girl immediately melted in her clothes, disappearing in it as she never existed. Jane walked toward what was left of her and under the clothes, took a dildo with her face appearing inside, too surprised to realize exactly what happened.

"W-What's going on... Jane... I feel weird..." Sarah said in a disembodied voice.

"Since you're not going to participate in anything, I made you useful to me."

The girl's image started to wiggle, trying to move without much success other than slightly bend the silicon cock.

"W-What did you do ?!?" She asked in panic.

"I turned you into a dildo."

"You biaaAaannh... !!"

Jane rubbed with her finger the base of the fake dick, giving an immediate reaction to Sarah stuck in it.

"S-Stop... Stop it... Mmmh..."

But Jane was having too much fun playing with it. And the dildo had its entire surface erogenous, which made Sarah unable to resist the pleasure. Jane then took off her clothes and put the dildo against her wet pussy. All she heard was her roommate saying "Don't you dare" before making muffled sounds.

Sarah felt Jane's vagina all around her, bringing even higher pleasure than anything she ever felt. She was shocked and disgusted by her position, but, the feeling was like nothing else. She felt something growing in her and pushing up, something deep and powerful, something that made her feel overwhelmed. And when she felt her roommate's vagina contract and getting spasms from an orgasm, the growing feeling exploded inside Jane womb.

Jane felt something warm filling her insides, and she felt the blood leaving her face. That wasn't supposed to happen. What was that ?? Taking off the dildo, it was just a silicon dildo, Sarah wasn't in it anymore...

"Oh, shit..." She breathed.

The spell wasn't just about turning someone into a fake dick, it was about impregnate oneself with someone's spirit... Sarah will be so mad in nine month...
