Not what you'd hoped

You think you catch a little embarrassment on Kevin's face, but it's largely overshadowed by an expression you can only adequately describe as 'very interested'.

It takes him a bit longer to adapt to what just transpired, but far from the desired response of Kevin getting angry and embarrassed enough to storm off or kick you out of the room, he's staring at you like he's never seen you before.

"You...you got really into that, huh?" His voice starts at 'taken aback' and slowly shifts into the 'smug' that you were feeling a few moments ago.

With you still on his lap, he has an easy time leaning forwards, lifting up your skirt, and confirming the presence of an extremely energetic erection.

He smirks at you, not seeming quite so embarrassed anymore with proof of your arousal in front of him. The fact that his cock completely dwarfs yours probably isn't hurting his confidence either.

The situation turning against you, you stand up, trying to will your erection away as you put on an indifferent expression.

"W-we're done then, right? I have another class soon."

You don't even make it a step before Kevin laughs and dashes your hopes.

"We're just getting started." You hear his fly unzip and then his pants drop to the ground as he laughs.

Looking back at him, you see that his cock is every bit as massive as it felt against your ass, and though it's slightly flaccid after cumming, the expression on Kevin's face makes you suspect it might not need too long before it's back at full strength.

You swallow nervously. Before, Kevin was power tripping ordering you around and using your body to get off.

But now, he's looking at you with a raw sexual hunger. You've provoked him by making him cum early, then shown weakness by getting aroused yourself...
