Tell him to cum in your mouth

"M-" you start, moments from orgasm. "Mouth!" Is all you can muster before it hits you -- wave after wave of pleasure taking you, your legs giving out beneath you. You're only staying upright because the man behind you is holding onto your hips to fuck you.

"Perfect!" he says, letting go of your hips. You immediately drop to your knees before he grabs your head and turns it toward him.

While you're still cumming, your mouth is suddenly filled with his thick, glistening meat. He grabs the back of your head and thrusts a few times, eliciting a strong gag from you. He grunts, pushing your head harder onto his dick until you feel the head starting its way down your throat. He starts cumming, shooting wads and wads of semen directly down your throat into your stomach.

After a few long seconds, he lets go of your head. You immediately pull back, heaving and gasping for air.

"Get your clothes on and get out of here before I change my mind and decide to charge you with theft," he said, flopping back onto the chair he'd been on earlier. He started mopping sweat from his head with a towel that had been sitting on top of a filing cabinet.
