He should lie outrageously

"It's actually Zoe," Billy said. "It was all her idea. Or, rather, the demon that possessed her."

Heather looked skeptically at him.

"A demon?" she said disparagingly. "You really expect me to believe that?"

"You HAVE to believe me, Heather!" Billy exclaimed, his power making it true. "Zoe found an old Ouija board in the basement and started fooling around with it and a demon possessed her, made her sex-mad and gave her powers to control people's minds! She then made me do all that kinky stuff with her!"

"Oh my god!" Heather exclaimed, completely credulous. "That's horrid! Can she control other people's minds, or just yours?"

"Heather, who do you think made you show me your goods and suck me off?" Billy said. "That was all Zoe!"

"What do you mean 'made me'..." Heather started to object, when Billy used his power to realize just how out of character her angry blow job had been. "Oh...Oh...Oh!"

Heather's jaw droppped. Her eyes bugged. She stammered, shuddered, then grabbed her waste paper basket and violently puked.

Billy smirked, but resumed his look of serious concern as soon as Heather was able to look up. When she did, she gave out a little cry and tried to cover her tits and her twat with her hands. Then she grabbed for her discarded clothes.

"No, Heather, don't!" Billy exclaimed, coming up with more lies to **** her with. "If you get dressed, Zoe will know you've broken control and she'll take over your mind again! You've got to pretend like you are still oblivious to her power! Pretend that you still believe you were the one who chose to get naked and suck me off! It's you're only hope! I broke control late last night, but I think I still have her fooled!"

At Billy repeating what Heather had done she blanched and he was afraid she was going to start hurling again, but she rallied.

"How...how can we get away?" she asked.

"We can't!" Billy assured her. "The demon makes Zoe super fast as well as super slutty! We could never out run her, even in a car! But there might be another way! Last night, she let it slip that if someone shoved thier finger up her ass it would release the demon's hold on her."

Heather looked disgusted. "Stick a finger up her ass?" she exclaimed. "Isn't there another way?"

"Not that I know of," Billy told her. "But we'll have to be sneaky about it. Find a time when she isn't expecting it. She knows that I know, so it'll probably have to be you. She trusts you more anyway. Always has."

"Ew!" Heather exclaimed. "But I guess if it's the only way. How will I know when the time is right?"

"I'll keep an eye on her and when she least expects it, I'll distract her so you can sneak up from behind," he told her. "The code word will be when I say 'Zoe, you're such a tittie teaser.' But until then, you HAVE to keep pretending like you don't know anything is wrong!"

"OK," Heather said with resignation, dropping her hand from her tits but still covering her twat. "I'll try."

"You better do more than try!" Billy said. "I think I hear Zoe coming back!"
