Right about now would be good

You don't think you want to give up sleeping, just like eating and drinking, there's something that feels good about lying down and drifting off when you're tired. Once you are in bed, you're too wired to fall asleep, though. You have a lot to think about. You wish away any fatigue, and you don't feel sleepy anymore. You lie in bed, looking at the ceiling and thinking about what you should do next.

In the middle of the night, Abbie comes into your room. She's wearing an old tee as a nightshirt. It barely covers her ass and is stretched tight across her big tits. She lies down next to you. "I can't sleep, Stretch. This is just too big to get my head around." You eliminate her tiredness for now. She smiles at the sudden feeling of being refreshed. "Thanks."

She presses her warm, soft body against your side and traces her fingers lightly up and down your bare chest. "Soooo... I know we just fucked for the spell to get rich. But now, I, I wouldn't mind doing it again. Knowing you're all-powerful and could just... do anything you want to me. It's so hot."

"I'm pretty sure Mom is having trouble sleeping, too. Aren't you worried she's going to come in and find you in bed with me?" you ask.

"I think Mom's going to have to get used to you doing what you want, with whoever you want," she tells you. "I'm pretty sure you're the one who makes the rules; you don't have to follow them anymore."

"Mom will think I made you feel this way, like that spell I showed you when I first found that website," you protest.

"How do I know you didn't, Stretch?" She gives you a foxy grin. "Speaking of which, if Mom is a problem, you could just change her mind, right? And, I'll be honest, when you showed me that spell, I thought it was kind of hot. I fantasized about a powerful mage taking away my free will and making me into his devoted thrall. If you want to, you could do that to me now."

"I didn't!" you insist. "You think I should mind-control Mom, and you? You approve of the idea?"

"It doesn't really matter what I think, does it, Stretch. You can do whatever you want with us." she giggles.

"This really gets you going, doesn't it?" you ask.

"You know what they say, power is the ultimate aphrodisiac. Especially for a little subbie-girl like me," she tells you. Her hand trails lower to your boxer shorts. She tenderly strokes your stiffening cock through the fabric. "Why don't you want to use this incredible power you have? Mess with our minds."

"If I just brainwash Mom and make her OK with everything I do, it'll be like admitting she was right. And if I make you, or any girl I want, just... do anything I want, it kind of feels just like I'm masturbating."

"Oh, trust me, Stretch, even as a mindless robot, I'd make you feel 100 times better than jerking off." Her fingers tighten on your now fully-hard cock. "Even if you didn't go for the 10-inch bitch-breaker."

"I still don't want Mom walking in on us," you say.

She brings her soft lips to your earlobe and whispers, "You could make her join us, Stretch. Give free rein to your mommy issues. Mom was hot for her age before, but now she's a fuckin' smokeshow."

Your cock strains and throbs. "Dammit, Abs. You are not playing fair. I don't want to mind-fuck our mother into a threeway with me and my sister."

Abbie starts kissing wetly down your chest. "OK, I guess you want her to come to you on her own, like I supposedly did," she teases. "You can be patient, you've got literally all the time in the world." She swirls the tip of her tongue around your navel, then down to the waistband of your boxers.

"Dammit, Abs, I didn't mess with your mind. This is all just your power-imbalance fantasies at work," you insist.

"Well, mostly that." She nods and tugs down your boxers. "And also the memory of getting nice hard fucking and hot wax treatment for the spell. I might have come back for more of that, even if you were just a wizard and not a god." She drags her flattened tongue slowly from the base of your cock to the tip. "I wasn't just being nice when I said your dick is perfectly good as is."

You become aware of your mother's footsteps in the hall. "Dave? Abbie?" she calls, "Is everything all right?"
