Lisa hugged him tightly. "The first time wasn't too great, but the second time wss much better. And something strange happened, that I don't understand. I feel like I have two slightly different memories of it."
"Oh," Ty said. He explained his lack of enthusiasm the first time, and how he'd psyched himself up to do it again. "Then I split my cock in two, without giving much thought to what it would do to you. It must have split you in two as well. And then when I merged my cocks back into one..."
"Yes, that must be it," Lisa said. "It was an interesting experience. Though I still didn't enjoy it as much without the mental changes. Next time I want the mental changes, as long as you're careful to make them temporary." She kissed him. "And don't forget, I promised that you'd get a turn, too!"
"OK," said Ty. "I have an idea about making sure the mental changes are temporary. Let's go back to the bedroom."
Ty had Lisa sit in her desk chair. "I'm going to talk to your 'operator' again," he told her.
"You're going into my mind again?" she asked. She sounded excited about it.
"I think it's dangerous to do that any more than absolutely necessary," he said. "I'm going to try a different approach."
She felt a change to her navel, and looked down at it. Where her usual cute little innie was normally found, she now sported a modular telephone jack. "Whoa! That's wild," she said.
An old-school desk telephone appeared on her desk. Ty plugged the phone cord into her jack. He picked up the handset, and heard ringing. After three rings, Lisa's eyes closed and her body slumped over. "Hello?" he heard, in Lisa's voice.
"Is this Lisa's main operator?" Ty asked.
"Yes, of course. I didn't think I'd ever speak to you directly again."
"I didn't either," Ty said, "but Lisa still wants to do extreme transforms, with mental changes. I have to make sure the mental changes are temporary, without needing the extreme measures we had to take last time to get her mind back together."
"I know she wants that, of course. I don't know the limits of your powers, but based on the previous experience with Cock wreaking havoc, I'll never again leave anyone else in charge here without my direct oversight. I have at least as much motivation to keep Lisa safe as you do."
"Good," Ty replied."I thought you'd probably feel that way, but I wanted to be certain."
"This telephone caught me by surprise," her operator said. "If we need to talk again, why don't you just come on in?"
"OK. I just thought this might be less potentially dangerous."
"Not especially. As long as we don't do anything other than talk, while Lisa sleeps, it's about the same either way."
"OK," said Ty. "Anyhow, that's all I called about. Unless you need anything from me, I guess we're done."
"Nice talking with you," Lisa's operator said. "I'll wake her up again. Bye!"
Ty heard a click from the phone, then Lisa awakened. "Wow, I didn't expect to suddenly fall asleep," she said.
Ty put down the phone handset, and unplugged the phone cord from Lisa's jack. "I think your operator wants you asleep when dealing directly with me, so that there's less that she has to keep an eye on. Anyhow, she confirmed that she won't leave your controls again, so as long as I'm careful at my end to make the mental changes temporary, everything should be OK." Ty made the phone vanish, and restored Lisa's navel.
"Thank you for checking," she said. She stood up, and kissed him again. "Are you ready to give it a try now?"
