Jon was liking his new changes, to his own surprise. What he was finding even more of turn on was his lack of control. Jon was kinda liking Zoe changing him however she pleased.
"Wonderful!" Zoe exclaimed. "This is so cool."
"I'm still weirded out by this," said Jon in his new feminine voice. "But this is kinda turning me on too."
Jon moved a dainty hand down to his new sex to find it warm and wet. Zoe watched, and followed the same motion to her own, finding a similar result.
"So, Jon... would you like to continue where we left off?" Zoe walked slowly over to Jon and grabbed him by his hips.
"I think I would," breathed Jon. They locked lips in a passionate kiss, and the twins moved in unison towards Zoe's bed, feeling each other up and grinding up on each other.
Just as Jon was wondering if he would have to go retrieve Zoe's dildo, he felt something pushing up against his stomach. He broke his lips away from Zoe's and looked down to find a very large penis, fully erect, emerging from Zoe's crotch.
Jon gasped, "It's so big."
"Just for you, Jon," Zoe smirked.
"How come I don't have one too?" Jon was mesmerized, he reached down to touch her throbbing member.
"Because I can control you individually now. So I can change you separately from me."
Jon wasn't sure he wanted that thing inside him, but he knew he was turned on by Zoe having one. When Zoe pushed him down on the bed, Jon found her penis right at the threshold of his awaiting pussy. Jon tried to wriggle away.
"Sorry, Jon. You're staying right there." Jon found he couldn't move, and was actually trying to thrust his hips closer to Zoe. Zoe's breasts were pushing into his identical ones, and the sensations were driving him wild.
"Zoe, no," Jon breathed. "You're too big for me!"
"Beg for it, Jon," Zoe commanded quietly. "Say you want me to fuck you with my huge dick."
All of a sudden, Jon lost control of his voice. "Please, I want you to fuck me with your huge dick."
If Jon had heard that voice when he was in his normal male form, he would have come right there. But now that voice was his own, but he was being forced to say it.
"Okay, Jon, you asked for it." With a grunt, Zoe thrust deep inside of Jon's pussy. Jon couldn't take it, her dick was too wide for him. But Zoe seemed to know that, and willed Jon's vagina to be wider to adapt to it. The sensations were amazing. With Zoe's huge tits waving in the air above him and grazing his own, and that monstrous cock pumping in and out of his sensitive vagina, Jon couldn't control his body. Not because Zoe was controlling it, but because he was too distracted by all the pleasure to think clearly enough to do so. And it was only getting better.
The tension was building and building deep within the core of his being, until it unleashed in an explosion of hot lava, causing him to scream out in lust and release. Zoe came almost immediately after him, thrusting deep inside him. They both spasmed, and Zoe collapsed on top of Jon. They both lay there panting, marveling at all the new sensations they had just experienced.
