"So Ema, what do you want to try?" Jeff asked.
Ema blushed and started to fiddle with the hem of her skirt before taking a deep breath and saying "Jeff turn me and my father Gabriel into female living gasm drives."
Jeff looked at her confused and asked "what's a living gasm drive?"
"Just put in to the Chronivac "turn Ema Smith and Gabriel Smith into the Tailor's female living gasm drive pets." Ema said not wanting to elaborate.
Jeff decided to not push further and do what she said. The moment he hit enter he saw Ema go to his bed and lie on her back as the changes began. Jeff watched her change into a living gasm drive
Ema felt her shirt tighten as her breast start to grow. Along her torso she also felt more tits start to form and grow. Her clothes quickly ripped off as she changed leaving her naked. She felt her legs meld together becoming an insectile abdomen, from her hips and along her torso she grow spider like legs. She grew until she was as long as the bed. She now had 10 melon sized tits, she grew tentacles out of her back and from the sides of her insectile abdomen. Ema's insectile abdomen ended in a large pussy. The fingers on her hands merge in till she only had two fingers.
Ema's neck lengthen and her head became like a snakes. Ema felt her new 20 foot long tongue in hew mouth, she felt how flexible it was. Ema felt her throat become another pussy, but despite this she knew she could still speak. the last changes she felt was in her crotch region. She felt she now had a cluster of 5 pussies there and her central pussy she had a long tongue like in her mouth.
Jeff looked at his what his girlfriend become. He was in a bit of shock but manage to say "you... you are like a sex beast."
"yup, that's kinda what a living gasm drive is" Ema responded "and as such that's one of the reasons I specifically said for female, since if you didn't put that I and my father might have become herms or males and I prefer to be female. As for my dad I always wanted him to be a woman instead since it's just him and me as you know. I have always dreamed of turning my father into a woman and sharing you with him/her."
Jeff stayed silent knowing he helped his girlfriend with her dream and knowing he will be reaping the rewards soon, so he decided to nod while looking at her with lust in his eyes at her new body.
Ema decided to wriggle in an enticing way before saying "hey Jeff I'm very needy now and need your seed, come on and fuck your new and improved girlfriend or should a say pet sex monster..... or would you like to take me and my father or should a say mother both at once, we are designed to fuck all day you know."
Jeff blushed and Ema's proposal.
Jeff decided to......
