Originally Jeff was secretly hoping to be turned into his mother's bra or panties but straight away realised something was off. As his mother laughed from behind the devices screen he saw his skin take on a silicone like sheen. As he looked up in horror he opened his mouth to shout to his mother to stop but once he opened his mouth, no sound came out and it became stuck in an o-shape.
His hair grew quickly down to below his shoulders, however that wasn't the only thing growing. From his chest to Lumos began to protrude, steadily growing in size until they became perfectly shaped D-cup breasts. As he tried to look at his mother he realised it was becoming increasing hard to move his body and that he no longer had to look down at his mother but rather look up.
Unable to look but feeling the last change in his body, Jeff felt his penis dissapearing into his now hollow self and feeling a tunnel appearing in its place. Once this was done he immediately felt himself deflating and after a minute he fell to the ground collapsing in on himself- 'or am I an it now?' Jeff thought to himself staring at his mother who was laughing the whole while. Before calling Jessica, Jeff's sister down to Jeff's bedroom.
"What???!!!" Jessica said as she came into the room before staring at Jeff- now a sex doll- semi-deflated on the floor. " I've decided that since Jeff wanted me to transform him into something for the weekend I thought I'd decide to make some profit off of it so how do you think of joining him, I'll give you 20% of the profit?" Jeff's mom said with an grin
"What? That's Jeff?!! No, I gotta get out of her-" Jessica's speech was stopped as instead of words, a white sticky liquid came out of her mouth. As she touched it with shock and looked at it the changes started immediately as Jeff watched on from the ground.
The first thing to happen, was that her breasts rapidly swelled and became semi-attached, as her legs and arms reduced themselves to stubs. Her neck became thick and being and elongated like a giraffe's at a slight angle forcing her to fall over, her head which was rapidly becoming a penis head, emitting semen from what was once the mouth continuously getting it all over Jeff.
As the legs and arms disappeared all that was left was the now human sizes penis that was on top of a deflated sex doll that was beginning to reinflate. As the cum covered Jeff, he felt ecstatic as the liquid was absorbed into him and filling him up. As he became inflated once again Jessica twitched and slumped in an effort before sliding into him. The feeling for Jeff was sensational despite the fact that Jessica was almost the same size as him.
"Right, now that you two are ready, I say we get the sex shop opened with you to, I trust you're ready?" The mom said, to which Jessica tried to shout no, only resulting in her cumming in Jeff even more.
