Jon Sarah and Jerry were going at it pretty hard. This was their fourth time meeting up like this as the sex was great. Jon was under sarah as Jerry was giving it to her ass when the change occurred. Instantly all 3 came as sarahs holes tightened. Her eyes were closed and her head titled back as her body scanned them. Normally as an android she would have time to scan them individually but being impaled by them her programming made her do it this way. Soon her pussy adjusted to jon and her asshole became a second pussy looser than her other vagina to fit jerry. In front her thighs and breast thickened while behind her ass enlarged and her back thinned out sensually.
She opened her eyes and woke up and started vibrating. "So where were...we? Right lets keep going you...twooooo"as he body started gyrating of it's own accord back and forth between them. They were shocked but too lost in pleasure to stop now. Jerry adjusted and held unto her breast. The moment he touched them they got bigger to match his hands. Then while jon was gripping her back he felt pressure under his palms. And found new breast growing to be held by him. Once her felt a nipple pop out he gripped harder and started going at it. This made Sarah and jerry go faster and soon all 3 came yet again. I think they'll continue having 3 somes more often.
