"I believe the car can wait a little while," Tina said, as Lisa began kissing the nape of that beautiful neck. She let out a soft, surprised moan that very much pleased Lisa to hear.
"I'm so glad to hear that," Lisa whispered, her kisses gradually moving higher up Tina's neck. As she worked her way towards the mouth, she felt a strange and extremely pleasurable sensation coming from her crotch. She looked down and was startled to see a tent being pitched in her pants.
She immediately pulled back from Tina and began scrambling to undo her belt and lower her trousers.
"What's the matter, Mr. Landry?" Tina asked, both concerned and frustrated that the foreplay had stopped.
"What... is that?" she asked, as she lowered her suit pants and boxer briefs to the ground and saw a very large — and unmistakably erect — penis pointing out where her vagina was supposed to be.
Tina looked down and giggled. "Oh, that?" she asked with a smile.
"Yes, that!" Lisa said, starting to panic a little. "I thought I was only switching lives with this guy! Why do I have his... his..."
"Penis?" Tina said. "It's okay, you can say it. It's yours for the moment." And with that, Tina reached out and put her soft, cool fingers on the head and shaft, working them up and down in a way that made Lisa's entire body feel like it was exploding with pleasure.
"Ohmigod, what is happening right now?" she murmured, barely able to control her vocal chords, let alone the rest of her body.
Tina continued to stroke Lisa's ever-expanding cock, and began getting down on her knees to take things to the next stage. "When we do same-sex swaps, we leave the bodies entirely alone, because that's not what the client is paying for. But we realized early on that for cross-gender swaps, some alterations were required to make things work. The new Lisa Hale wouldn't truly get to enjoy her transformation if she couldn't enjoy sex the way any other 18-year-old girl could."
This made some sense to Lisa, but her logic centers had been put on hold, and all she could focus on were the sensations coming from what Tina was doing to her new male anatomy. She looked down and saw Tina smile up at her, before the hand job became a blow job, and Lisa lost control of her body and mind altogether.
