I'm comfortable enough where I am

Somewhere in the back of my mind I recall that I can get off his lap now, but instead I wiggle a little on his lap and against his cock to get more comfortable, that voice in my head having as much say in what's happening right now as my boyfriend in our apartment. As far as he'll ever know, I'm working hard on my project.

"So, Emily, truth or dare?"

"Truth," I felt like I'd been doing too many dares anyways. It would be really bad to let this go any further.

"How big was the largest guy you've had sex with?"

"Like his penis? I didn't exactly measure but," I pulled out my phone, "Like this long? Five inches, maybe six? And about this wide." I made a circle with my thumb and pointer finger that was maybe a little wider than a quarter. In fairness, I'd only ever actually had sex with my boyfriend, and all the guys I'd fooled around with otherwise were only a little bigger.

"Interesting, very interesting," he said, casually resting one hand on my upper thigh. By now his cock was hard like an iron rod under me, and most certainly both longer and thicker than my boyfriend or anyone else I'd been with.

"Truth or dare?"

"Truth, since you did it."

"Who's hotter, Amy or me?" Our absent lab partner was, in my opinion, much hotter than me. She was thin and tall, always well dressed and had great makeup, while I was chunkier and tended to wear more baggy shirts and loose jeans.

"You, by far. Amy is pretty, but she's not as hot as you."

"What? No way, come on."

"She's really pretty, but she's like a stick. You've got the kind of figure I like, you're curvier and way hotter."

"So it's just because I've got big boobs and all my fat goes to my ass?"

"Basically," he replied, laughing. He then gave me a gentle slap on the ass, laughing as he did. I grinned, slowly, ever so gently grinding down a little bit against him. I was immediately rewarded when his other hand went to my other lap; now he was sitting with my ass squarely against his cock, both hands just inches from my pussy. "Now, truth or dare?"

"Dare," No hesitation at all. By now any voice in the back of my head or moral compass had been thrown out the window.

"Turn around and face me?"

Wordlessly, I stood and stretched a little. He scooted to the middle of the couch and adjusted his cock in his pants; it was now just barely covered by the hem, pointing upwards. I straddled him, my face now a scant few inches above and away from his. He alternated between staring at my tits and face, not even attempting to hide his lust. Now that I had my legs apart, pressing my crotch to his became much, much more intimate. I could feel how hard he was just separated by some flimsy panties and pants, and I made the barest of hip motions to better press his shaft against my pussy.

"Well, isn't this better?" He asked, casually setting his hands on my hips. He was acting like he owned me now, and I loved it. I put one of my hands on the couch to balance myself, the other gently on his muscular bicep. I could feel him flex as I touched it, muscle tensing up then slowly relaxing.

"So, truth or dare?" His half lidded eyes watched my mouth when I talked, as if he considered cutting me off entirely with a passionate kiss. They flipped to my tits, taking in the lily-white cleavage which was exposed by the translucent white tee shirt.

"Truth."

"What are you thinking about right now?" A simple question.

"Just thinking about what I'm gonna dare you to do." He smirked, one of his big hands snaking back to rest on my ass, the other sliding up to rest on my side, with only his thumb ever so slightly on my breast."

"Oh really? That's kinda a cheap answer, but it's good enough." I could feel my mind overheat. If I answer dare, I can only imagine what he's gonna do to me. And everything I'm imagining is just getting me hornier and hornier.

"So, truth or dare?" He piques an eyebrow, his hips gently pressing upwards against me and his hand on my ass ever so slightly pulling my hips against his.
