The scientist decides to sell her to a store for sex toys. As he pondered how to do it, he thinks about the size of his new toy.
He feels like she is to big and it would be unhandy to have her like she is now.
He attached the machine back to her and tempers with it a little. "I'll make you into an onahole and sell you to a store after wards, the funding for this isn't coming out of nowhere"
The no-longer-girl lies there without motion, cum still dripping from her opening. She heard the scientist say something but is still to intoxicated to process it. She doesn't realize that she is now reattached to the transformation machine.
The scientist hits the start button and the changes on the toy start. She starts to shrink to about 10 inches. Afterwards the hole that is her vagina starts to expand inside her body making just enough room for a dick to fit inside. As the transformation nears it end her mouth opening and her vagina connect to form one tunnel, waiting to be fucked.
"Will this really be my new life now?" Thinks the girl. She sounds depressed about it at first but memories of the scientist cumming inside her came back. If she could she would have blushed. Thinking a bit more about the situation she is in now, she comes to the conclusion, that it isn't that bad. She liked being fucked and as the scientist said there is no turning back anyway, so she might as well enjoy the time she has as a mere toy. That being for ever. As the changes start she is surprised because she doesn't know what is happening. She realizes that she is shrinking and once the shrinking has finished she is a little sad, because with a body this small she won't be able to get fucked anymore. That's when she recalled the scientist mentioning onahole to her. She get exited and starts to mentally moan as her vagina expands taking up most of her interior.
As the transformation is finished she lays motion less in the table. The transformation made her really horny and so she is pretty happy wenn something is pushed inside her, but she sone realized that this something was a stand for sex toy like the one she is now. Now she just stands there on the anal plug shaped pole. The scientist left the lab, only to return in the morning of the next day.
