"...you would tell me your deepest, horniest desires and then forget you told me." Jake said. Jake's mom Jen then in a trance like state said "I had always wanted to slowly transform into Satan while having sex with our neighbor Gabriel, as he turned into Lilith and we would take over the world as husband and wife."
Jen further elaborated on her deepest desire by saying "we would still remain our selves but very much be Satan and Lilith, we could of course change our appearance to any horny persons deepest desires and fetishes but we wouldn't be able to change our sex."
"I would be a man and Gabriel would become a woman."
"we would start having sex then slowly start transforming feeling good as we change, the changes would take at least a hour and we would have micro orgasms throughout our change, then we would reach our climax together as we finish our transformation into the king and queen of hell."
once she finished all that she went back to looking for the T.V. guide as nothing had just happen. Jake decided to grant his mother's deepest desire.
Jake made his wish "I wish what my mother deepest, horniest desire would come true and they would both be aware of the changes happening to them and love it.
Jake then wished "my mother and neighbor would have sex on the couch, and that they would allow him to watch."
Jake heard the door bell and saw his mother stop looking for the T.V. guide and go to answer it. Jake got off the couch and went to sit in one of the nearby chairs knowing what was going to happen. Jen came back with their neighbor Gabriel and they started to undress themselves as they got to the couch. Jen sat on the couch nude while Gabriel moved to be straddling her, Gabriel gave a passionate kiss to Jen. Jake saw his mother grab Gabriel's hard cock and began stroking it, Gabriel moved his hands to be playing with her breasts. Jake unzipped his pants and took his hard dick out, he began to slowly stroke it knowing the show was just beginning.
Someone please continue this I'm not good at describing slow transformations, and I would really like to see this continued.
