Getting over the post orgasmic glow Nikki stepped out of the room and rang Jessica.
"That transformation you gave me wasn't to bad," said Nikki when Jessica picked up the phone.
"Oh, you're not done yet," replied Jessica. "You're only half way through your changes."
"What do you mean by that?" she asked, but Jessica had already hung up the phone and was giggling to herself at the thought of her friends future change.
Putting her phone back into her purse, she could help but keep thinking about Max's cock. How she loved being filled with it and couldn't wait until she was again.
"No!" Nikki said to herself. "You have work you need to do, you can't be thinking about that wonderful cock and how great it was."
Looking down Nikki saw that she was rubbing her crotch with her realising it.
"Well, maybe one more time to get it out of my system." she said.
Walking back into the room she saw Max with his pants still off, which got her mind fully focused on his cock and how much she need it.
"Time for round two buddy," she said, throwing herself on him and impaling herself on his cock.
Once again she could feel her pussy squeezing his cock. Squirming as she felt so good. Wanting to feel it better, she twisted around to get into doggy style. Max keeps thrusting into her and she feels her pussy becoming tight and squeeze his cock for all it's worth until it explodes and she feel his cum flow into her again.
"Wow," she said after coming down again. "You really are good at this."
Nikki then tries to get off of his cock but finds she can't.
"Wow, you must really have pounded the strength out of me with that last go." she said.
Looking down at his body she realises that something is different down there, she can't see where her crotch ends and his begins.
"What happened to our crotches?" Nikki exclaimed.
"What do you mean?" replied Max. "I know you're a bit light headed after masturbating but you're not that dumb. Let some blood rush back into you and you'll be back to walking soon."
"What do you mean masturbating?" she asked. "We just had sex."
"Nikki, you have to stop thinking about that as sex." Max said. You're my cock, so you can't be having sex with me."
Looking back down at her crotch Nikki realised that her crotch continues into Max's crotch and that Jessica must have turned her into Max's cock.
