Let her finish you

Mark took a quick glance around the room again to make sure nobody was looking at what was happening under their desk.

“fuck,” he muttered under his breath, Ali’s was squeezing his dick even harder, getting him closer to that all important release.

“Ali... uhhh... I’m about to cum, maybe we should stop” he mumbled to her.

Ali returned her focus to him, still jerking his dick up and down.

“You want me to stop?” She asked, “I don’t have time later today to finish you off”

Ali continues to stare at him, her lips slightly parted, those sexy glasses, her messy bun. The look she gave him was of pure lust and desire.

He knew he could make a mess everywhere but Mark found it almost impossible to tell a hot girl like Ali to stop touching his dick.

“Ummm... uhhh... fuck it... just keep going Ali” he very quietly moaned.

She gave him a grin, had bright white teeth sparkling at him as she picked up the pace again with her left hand.

Mark could feel the pressure building with every pump of his dick. He could feel the cum building with every stroke, Ali now staring at him, paitently waiting for the explosion.

Mark held his mouth shut as he felt his orgasm come, he didn’t want to make any noises that attracted unwanted attention.

Spurt after spurt, he realeased himself in Ali’s hand.

Ali smiled as she slowly stroked his cock to let out all of Mark’s cum. Most of hit had fired straight up, hitting the bottom of the desk, the rest dripping over Ali’s left hand and the front of Mark’s shorts.

They both discretely looked below the desk to check out the mess.

“Fuck, I’m going to have to hide the front of my shorts with my textbooks or something, this is a fucking mess,” complained Mark quietly to her.

Ali helped put his recovering dick back inside his shorts while wiping her hand on his upper leg and knee.

“Sorry babe, Just have a shower once you get out here” she said smirking playfully.

When the professor dismissed the class at the end of the lesson, Mark waited for the rest of the class to leave first, he walked behind Ali at the back, holding his textbooks close to his shorts to hide the mess.

Ali turned her head back as they were exiting and gave him a cheeky and flirty smile. He could tell that she loved how uncomfortable he was at the moment, all from what she caused.

“So I’ll see you around Mark” she smiled, blowing a kiss.
