She'll suck the truth out of him!

"What more can you possibly do?" Billy asked, willing for her to notice his raging hard on and come up with an idea.

She glanced down at his dick, her eyes going wide, then she looked back at him coldly.

"If you don't tell me what you did to Mom," she said with fatal seriousness. "I swear to God I will suck your dick right here and right now and there's nothing you can do to stop me!"

"You wouldn't dare!" Billy egged her on. "You can't fool me! You've never given head in your life!"

"Show's what the fuck you know!" Heather exclaimed as he re-wrote her own memories. "You know what the other sluts call me?"

"Girl-who-doesn't-dare-suck-dick?" he guessed.

"Wrong! They call me Penis-breath!" she said, putting forward her chin defiantly.

"Oh, I'm so scared!" Billy said and stuck his tongue out at her.

"Don't say I didn't warn you!" Heather said, fiercely kneeling before him as he sat on her bed, licking her lips and taking he cock in her mouth.

"Oh no!" Billy exclaimed. "I didn't really think you'd do it!"

Then he giggled, leaned back and grinned from ear to ear as she angrily tried to suck him off, thinking how very good it was to be himself just then. She was actually better at sucking cock than Zoe was, though whether that was due to practice or sobriety he wasn't sure. Maybe he'd have to hold some kind of contest. Best seven out of ten for both of them sober and then shit-faced drunk. It could take quite a while, but really it was the only fair way to compare the two playthings he lived with. He wouldn't count this one with Heather. Zoe got some warm ups. It was important to be fair.

"God, I never would have guessed you were such a raging cock sucker, Heather," he commented.

"UnnghMmmn!" she replied with angry pride, not breaking the rhythm with which she bobbed her head along her rod.

"It must be because you love it so much," Billy said, focusing his power. "I mean, even though you hate my guts, this is still making you totally hot, isn't it? It's getting you all wet, getting your nips and your clitty all hard."

"Unnnnnnn!" she moaned and her mouth got wetter, presumably mirroring her other end.

With a thought from Billy, Heather reached down under with the hand that wasn't stroking his balls to finger herself. She shuddered and her fellatio became a bit more sloppy and she began bobbing her head with more heat than anger. Billy reached out to stroke her head and the soft sensation set him off. He groaned and started cumming.

"Bet you can..." he started, intending to dare her to swallow, but words failed him in his orgasm. His power rose to the challenge, though, and she lapped and swallowed greedily.

He lay back on her bed, grinning at the ceiling and riding the wave of pleasure. After a while, he realized Heather was quietly moaning. He looked up to see she was frantically masturbating, rolling around on the floor. He lazily enjoyed the sight, Heather oblivious to the audience. At last, she peaked, shuddered and whimpered, going limp all over.

"Well, you certainly showed me," Billy said.

"Huh?" she said, looking up and blinking, trying to focus and remember where she was. "Oh! Uh, yes! Yes I did!"

She got up a bit wobbly, still trying to focus.

"And don't...don't think I won't do it again!" she threatened, with an involuntary quiver of her lower lip.

"I believe you!" Billy admitted.

"So are you going to tell me why Mom is doing all that...stuff...with you?" she demanded.
