I swallow—hard.
“Not when you’re around me,” I say.
“Are you thinking about how warm and wet my pussy is for you?”
“Holy shit.” The words come out in a near-silent whisper. I swallow again.
“I’ll take that as a yes.” She runs her hand down, forcing my legs slightly apart so she can cup my balls. She presses her thumb at the base of my cock, and I gasp.
“I want to suck your cock.”
I blink. For a moment, my brain seems to shut down entirely.
Riley has never said anything remotely like this before, and I don’t know what to do.
“Okay,” I finally whisper in a husky voice. I swallow and repeat myself. “Okay, yeah…uh…that works for me.”
She presses her lips together but can’t stop her grin. It lights up her whole face as she drops to her knees in front of me. She grabs the buckle on my belt and releases it. I don’t move. I can barely wrap my head around what she’s doing as she grips the hem of my pants and yanks them down along with my boxers.
Resting back on her heels, she looks me over appreciatively. My dick bobs in front of her face as if it has a mind of its own, and the only thing it wants is her touch. It’s very close to the truth.
She drags her finger over my balls and up my shaft. She circles the head with a fingertip as she caresses my thigh and then wraps her hand around me. She tilts her head up, her eyes on mine as she slowly moves forward and takes me in her mouth.
She sucks me in until I feel the back of her throat against me. I tense, holding myself still and fighting the urge to shove myself farther in. She pulls back, releases me, and then licks my cock up and down the shaft. She circles the head with her tongue, then takes me in deep again.
Her eyes never leave mine. I think I now know the definition of “bedroom eyes.” Her lids are half closed but her gaze still intense. I reach out slowly and place my hand on the back of her head, twisting my fingers around her hair. I don’t pull. I want this to be all her.
I’m overwhelmed by the softness of her hair wrapped around my fingers, the caress of her lips on my shaft, and unceasing suction around my cock as her tongue slides over me. All of that combined with the look in her eyes as she sucks me farther in is too much.
I can’t look anymore. I tilt my head back and close my eyes. It doesn’t help. The tension is still rising through my cock and balls. My thighs tremble. I grit my teeth, trying to hold back, but I can’t.
“Riley!” I tighten my grip on her hair. It’s the only warning I can give her.
She hums around my shaft and sucks me farther into her mouth until I’m pressed against the back of her throat. My cock spasms, and I’m unloading into her mouth. She grips my thighs tightly but doesn’t release me from her mouth.
My knees almost give out on me, but I manage to stay upright—barely. Riley keeps sucking, swallowing everything I’ve given her and then licking around the head of my cock before she finally releases me.
“I’ve wanted to do that for a while now,” she says.
“Wha…wha…why did you wait?” Coherency is lost to me.
“I don’t care for an audience.” Riley smiles and shakes her head. “It can’t be avoided in the lab.”
“The mirrors.”
“Exactly.”
“But…whoever is in there, they’ve seen us.”
“They’ve seen you have sex with me,” Riley says. “It’s part of the program, as far as they’re concerned. It’s just you releasing energy like you do at the gym or in a training session. Tonight will be different.”
Tonight will be different.
The future tense isn’t lost on me.
“More, then?”
“Definitely more. I have data to gather, you know.” She winks at me.
“Data?”
“I want to know what your minimum refractory period is.”
“Refractory period?” I know I sound like an idiot, but I’m still trying to come to terms with her changed demeanor.
“How long it takes for you to be ready to fuck me. How many minutes before that thick cock of yours is hard and throbbing again.”
“Jesus,” I whisper. I lick my lips. “Just keep talking like that. I don’t think it’s going to take very long.”
“Good.” She tilts her head and looks at me quizzically. “Let’s see how you respond to visual stimuli.”
She takes a step back, reaches up, and releases her hair from the bun. Her hair falls around her shoulders in a cascade of light brown waves. She shakes it out and tosses the hairband onto the floor.
She’s breathtaking.
I watch as she discards her lab coat and begins to unbutton her blouse slowly. I can see just a hint of pink beneath it, and I wet my lips with anticipation. Once the blouse is undone, she leaves it on, teasing me with only a quick glimpse of the pink bra beneath it. She reaches behind herself and unzips her skirt.
