Jane felt the urge to go to the bathroom, Tina felt the sensation in too as her stomach turned into a bladder connected to Jane, like wanting to vomit, it wasn't an horrible feeling but rather a pleasurable one, maybe could think of it as a little the same as cumming.
Jane was about to sit on the toilet as she got used to pee sitting on it, but remembered that now she had Tina, she needed Samantha to close her mouth to make Tina pee from hers, otherwise she would have ended making a mess pissing from both her penis and vagina.
Tina shot a stream of the yellow fluid from her mouth, her taste was modified to like it, she enjoyed to expel the urine of her temporal owner. She purposely moved herself slightly to the left and make Jane miss at pointing the toilet.
"Hey that's not fair, you're making a mess!" Jane laughed and Tina giggled too. Jane held her hand on her to be sure to not miss again.
"It's your fault for not holding me while peeing!"
"You're such a messy cock, it will take me a while to correct you~" Jane said smiling and cleaning some of the pee on the floor
"Oh much better!" Jane wiped her cock making Tina shake while dropping the last bits of pee. "How was that?" She asked leaving the bathroom and going to her mom's bed, which felt like it was hers.
"That was really good, you taste really sexy~" Tina said making Jane blush and get an erection, Tina felt how blood pumped through her body making her bigger and stronger.
"You're just giving me a boner! What about having some time together~"
"Oh you kinky milf~ of course I want! Play with me as much as you like, I'm your cock now"
Jane started to massage her human cock, Tina was loving the sensation too, like being hugged by her giant hand but also stimulating her, a mix of sensations that she couldn't forget.
They kept spending time in their horny session until Tina started to cum from her mouth. The feeling wasn't comparable to peeing, it felt a thousand of times better, vomiting tons and tons of cum from her mouth,
Jane licked all the cum that fell on her hands. "You taste sexy too~", cleaning the rest of the cum on the bed.
"I'm glad to hear that, it'll be an honor to live these days as nothing but your cock!"
"I can't wait for that too sweetheart~" Jane cleaned Tina's mouth too, which was difficult to do without moaning as her head was really sensitive.
Jane really loved the sensation of having her new cock, she loved it so much that didn't want it to end, she knew that she promised that the transformation was going to last only one week, but she also feared to become like Hilda and Layla, obsessed with her powers.
