... close..." (v.1)

You can guess why he is so impatient, judging solely by how hard his clothed cock is digging into you. All you can manage in response is a hurried nod. He smiles, ensuring you are steady on your feet before peeling his body from yours, leading you through the building.

You barely go a few meters before he looks down the hallway both ways, ensuring no one is looking, and pulls you quickly into the men's room. In this moment, you couldn't care less.

The room is actually rather clean-- the janitor must have been in recently. Keith leads you into the far stall, closing the door behind you as he pulls you into another passionate kiss. Your arms drape over his shoulders as you return the gesture with the same enthusiasm.

Within a minute, your shirt is around your neck like a scarf, keeping it off the floor. You bite your lip nearly to the point of bleeding, trying to keep quiet as your professor lavishes your breasts with the attention of his hands and mouth. Your fingers absently run through his hair, subconsciously keeping him in place. You whimper when he does pull away, disappointed and feeling the chill crossing your now-ignored flesh.

He makes it up to you almost immediately. You fail to stifle your moan as his left hand nudges aside your underwear, his right fumbling with his own pants. Soon enough, he has extricated his cock from its confines, the head bumping against your lower lips impatiently.

He kisses you hard, swallowing your pleasured cry as he shoves himself inside you again. This time, he begins with an eager pace, hurriedly thrusting as he pushed you back against the stall door behind you. You can hear and feel the light, metal construct rattling, the sound echoing in the tight room. Clearly, all concern over getting caught is out the distinctly absent window.

You have no hope of stifling the moans and cries Keith is driving from you, releasing them all into his dominating mouth. The writhing of your tongue is a weak mockery of resistance, all control over your body given to him. Your fingers dig through his shirt into his back, clutching on for dear life.

Already, your eyes are trying to roll. With how quickly you got back to fucking, your prior high had barely faded. You feel your climax coming rapidly.

A tiny voice in your head tries to remind you of your prior relationship to the man currently pushing you towards heaven, one thrust at a time. Right now, you couldn't care less. In fact, the more you remember how wrong this is, the hotter it gets. Doing something so forbidden...

That thought and a particularly hard thrust drive you over the edge. Your legs rise from the ground, wrapping his waist to clutch on just as tightly as your arms. A scream of pure ecstasy rips through your throat, his consuming mouth unable to mute it, your vaguely-muffled voice echoing loudly. He keeps going, barely slowing down solely due to your clenching muscles trying to arrest his movement. The continued stimulation drags your orgasm on, extending the mind-melting release longer than you ever thought it could last.

Finally, your muscles slacken somewhat, sapped of strength. He separates from your mouth, breath heavy and periodically interrupted by grunts. After a few more thrusts, he rips himself out of you, cum immediately striking your labia. He was that close to cumming inside of you?

For over a minute, the two of you struggle to catch your breath.

"I..." he starts, still struggling to replenish his lungs, "I... would very much like to continue this..." You blink, meeting his eyes, chest still heaving into his. "Not just tonight..." You interrupt your slowing gasping to swallow.

"I-I..." you stutter, running one hand down his back a few inches. "I-I... would like that... too..." He smiles, placing a brief kiss on your cheek. Your legs finally fall gently to the tiled floor, heels tapping down audibly. For another minute, the two of you just stand there, embracing one another as your lungs satisfy their need.
