Chapter 2: Stephanie & Sheldon

Summary:

Stephanie meets with Sheldon to talk about their upcoming classes.

Chapter Text

Steph hoped Shel hadn’t noticed her crossing and uncrossing her legs while she talked with him. He was sitting with an open stance, his legs open and nonchalant. And all she could think about was kneeling between them and sucking him off. She could feel her clit engorged by her arousal, and the slickness of her pussy dripping wet, but crossing and uncrossing her legs wasn’t helping enough.

“…and I’m hoping to get those analyses run before Wednesday…” What analyses? She couldn’t even concentrate on what he was saying like this. She wondered if she could flash to the bathroom and rub one off fast enough that he wouldn’t realize she had even gone anywhere. She licked her lips. Something told her it would be faster if she could just suck his cock though. I’m such an insatiable slut all I can think about is his cock on my tongue.

“Are you alright, Steph?” Sheldon leaned in closer, moving his chair closer to hers.

“Um, yeah…” she swallowed hoping it would clear some of the lust in her voice “Did you need help with those analyses?”

“I would actually like your help, if you’re willing. But, ah, I can’t pay you for it. Not in financially-relevant ways anyway.” He fidgeted sheepishly.

Do I dare? “Let me suck your dick and I’ll do it.” She blurted out and then put a hand over her mouth.

“You want to suck my dick to then do something for me?” He laughed “That’s pretty unusual.”

That’s not a no. “I—just want to know how yours tastes.” She clarified, biting her lower lip in a way she hoped was at least a little sexy. She had accidentally played her hand but it wasn’t blowing up in her face just yet, so maybe.

“Let me text my wife and check if that’s alright first.” He said, picking up his phone to text her.

“Of course, of course. I need to do the same for Bart.” She actually picked up her own phone and texted. “The impossible is happening. Sheldon is open to sex, assuming wife green light. How about you?”

Sheldon’s phone beeped a return message about the same time as Steph’s chimed with Bart’s: “Him with you, yes. But only if you enjoy it. Him with me? Let me know if he earns it.” Sheldon with Bart? Her eyebrows lifted in surprise at the thought. She hadn’t considered that before.

“Wife says I’m good.” Sheldon interrupted her thoughts of both the men she lusted after having sex in front of her, and she was reminded of the real prospect she had literally in front of her. “You got clearance from Bart too, right? He’s a big man that I’m pretty sure I don’t want to piss off.” Steph nodded. “So how do you want to do this?” Sheldon leaned back in his chair.

Almost faster than he could blink, she was on her knees in front of him (She wasn’t stupid enough to reveal her powers just to get his dick in her mouth faster.) She looked up at him, putting her hands on his pants, rubbing against them gently to find his stiffening dick. Then slowly unbuttoning and unzipping, pulling out his sizable length. It looks just as good as I imagined. Steph licked her lips, then licked the tip of his dick. Pleasure shot to her clit immediately, making her need. She took the head of his dick in her mouth and the pleasure just got stronger. She could feel her orgasm building as she licked all around it, moaning every time she took it deeper in her mouth.

“I hope you don’t mind me saying, but you’re a bit of a slut aren’t you?” Sheldon asked. She moaned in response, nodding as she continued sucking. “Getting off on just sucking my dick.” He put his hand in her hair gently, running his fingers through it. “Do you really crave it that much? Do you want my cock deep down your throat?” She looked up at him and moaned, eager for it, his hand gripped in her hair. Please fuck my face and make me cum until all I can think of is your dick. Please—Master.

Sheldon started thrusting into her mouth, and immediately she felt wave after wave of pleasurable orgasm from him using her mouth. Just like she had with the guardian.

“The smartest fucking student here, and I’ve got you on your knees, that smart mouth around my cock and you’re begging for more.” He taunted her as he fucked into her moaning throat. “I’m – I’m--- Swallow, slut.”

She tasted his cum on her tongue and could no longer hold back. Her whole body vibrated with the final orgasm as she swallowed his cum. When she came back, after nearly feeling out of her body, she expected to find Sheldon awestruck or very confused. Instead, he just looked at her expectantly. Disheveled, and taking deep breaths to recover himself, but expectant.

“Have you really not put it together yet, Flare?” He asked. “You’re supposed to be smart. Though I guess maybe all the blood to run your brain isn’t there right now after what we just did.”

He reached in a nearby bag and pulled out the Guardian’s cowl, laying it on his thigh where she could see it.

With an expectantly arched eyebrow, Sheldon watched Steph’s eyes grow wide.

Notes:

I may retcon this ending (kind of a sucker for Identity Porn), but for now I like it. What do you think, reader?
