Trevor looked up at Betty, his eyes wide. He was having trouble talking, having trouble thinking. Her warm weight pressing down on him occupied most of his thoughts. Still, he tried to focus. There were reasons he hadn't brought things to this point. Things they needed to talk about.

"Betty..." he started to say, but she put a finger on his lips.

"No. Listen now." She told him. "In our recent battles, I had to dig deep within my mind. And what I found there was lust. A great many fantasies, most of them about you. I now also have two people to discuss this with. A literal demon and an angel on my shoulders, even if one of them is a duck. They both agree there is no reason we should not let lust overcome us. For different reasons, but still.

"Also, in order to gain access to the fire aspect of my own nature, I had to think about you in a great many complicated and intense positions, and I have now become horny."

The corners of Trevor's mouth twitched up at the sides. She hadn't broken her monotone the entire time. It was the most... the most Betty seduction ever. But still...

"Betty I could hurt you," he said. "I'm strong Betty. Too strong. I know I mostly have to call on it on purpose, but sex... there's a lot of involuntary muscle movement during sex, Betty. I'm scared I'll lose control."

"I see," Betty nodded. "I have two counterarguments. The first is that Kyle is almost as strong as you are, Jenny isn't much stronger than me, and they have had no problems. But that is only my first, and less convincing, argument."

"What's the other one?"

Instead of responding, Betty pulled off her sweater and the t-shirt underneath in one smooth motion. She had either pulled off her bra as well or she hadn't been wearing one because her breasts spilled free, bouncing and swinging with a hypnotic motion. Trevor gulped, unable to pull his eyes away.

"The answer to your concerns is simple. Do not attempt to control yourself. Let me control you."

She slid Trevor's shirt up and leaned down, her breasts mashing against his bare stomach.

"You find my chest enticing." She kissed the muscles of his chest, and her lips felt like fire on his skin. "I find yours enticing as well."

"Glurp," he managed.

"You will lie beneath me." She continued to kiss the muscles of his chest and stomach. "You will do as you are told. You will obey. And you will not lose control and hurt me, because be in control."

"Yes ma'am," Trevor shivered.

"And you will continue to call me ma'am, because that is extremely erotic. Take off your shirt."

He hurried to comply. As he did he felt her weight lift off of him for a moments, and he realized she was taking off her pants. For a moment he kind of envied Kyle. This part must be a lot easier with telekinesis. But once the shirt was over his head, all the thoughts vanished.

Betty was beautiful.

He'd known that, of course. But it was different, having her here like this. Her body, normally hidden by the bulky clothes she wore, was now covered with nothing but moonlight. As his eyes traced her curves he realized he must be the only person to ever see her like this.

"You're beautiful," he said.

"Ma'am," she reminded him, though her cheeks flushed at the compliment. It was typical that straddling him naked, a compliment was what made her cheeks flush. "You will remember to call me ma'am. Be a good boy."

"Yes ma'am."

She raised her hips again, her hands trailing down his stomach to his waistband, unbuttoning his fly and pulling down his zipper, pulling his cock out into the cold night air. He could have been in a glacier at this point and it would still have been rock hard in her hands.

"As I expected it is a very commendable size," Betty said.

Trevor wanted to laugh at, once again, Betty's extremely Betty approach to the situation. But his mind was so full of swirling thoughts and emotions he felt jammed up. The quirky behavior that had attracted him to her at first. Her beautiful body. The warmth of her skin on his. And the fact that he'd never done this before. But then neither had she, she'd told him that. And besides...she was in control.

"Thank you ma'am," he said.

"I have many ideas for complicated things we could do with each other, but I believe it will be best to start simple."

She lifted her hips one last time, lining his cock up between them. For a moment she didn't just look beautiful, she looked... perfect. Trevor's breath caught in his throat. Every line of her body, every caress off the moonlight, guided his vision down, lower, until it locked on the small trim triangle of hair between her legs.

And then she descended on him and his world went white. Her body seemed to devour him, and he gasped aloud as she slammed down onto his cock, taking it all inside her in one swift motion. Beyond his control, his hand reached up to grab her hips. She didn't object, just began grinding her hips against him.

"Holy fuck," he gasped. "How...how did you just do that?"

"I am borrowing the instincts of my new summon," she said. Her usual monotone voice was breathy, a little ragged. "A demon of lust itself. And you have forgotten to call me ma'am. Don't you want to be a good boy?"

"Yes ma'am. More than anything in the fucking world."

"Then start moving your hips," she ordered, and he obliged, bucking up into her as she came down. "Twist them. Compliment my motions."

"Fuck...dammit Betty, I'm gonna..."

"No you are not," she informed him, the rhythm of her hips changing, the urgent pressure backing away.

Around the second hour, he came to appreciate just how dangerous the sexual knowledge of a succubus could be. It would be wrong to say she used him. Every motion was with him, for him. What she did was lead him, drag him along almost. Somehow, with subtle motions of her body, she trained him to please her bit by bit.

After all, she was in charge.

And three times, the frozen, still mask of Betty's face broke. Three times her body shuddered, clutching him inside, her face flushed down her breasts, her head pitched back and she let out a... it wasn't quite a scream or a moan, something in between, a long low noise of intense ecstasy.

The third time, she finally let him cum. He grabbed her hips and buried himself inside of her for their final, mutual moment of mindless bliss.

Then they both collapsed to the forest floor, and she cuddled up to his bare chest. They lay there fir a long while, holding each other, their minds lost in the sparkling golden droplets of their afterglow as they slowly calmed down.

"That was extremely satisfactory," Betty said.

They had managed to keep the noise down for hours, left alone by their friends, but now they had to scramble to find their clothes. Trevor had burst out laughing.
