You stall for time

"I'm sorry?" You stutter.

Miss Desmond glares at you, "Hurry up, young man, we don't have all day."

The girls in the class giggle.

Reluctantly, you unbutton your shirt and drop it to the floor. Next come your shoes, then belt. When you get to your pants you delay once more.

"What's wrong now?" Miss Desmond asks, "I assure you I've seen it all before."

You take a last look at the class around you, then in a single motion slide off your pants and boxer shorts. A few of the students gasp at the sight of your nudity.

"Much better."

Miss Desmond splits the class into pairs, handing each pair a digital camera. You can almost feel your balls shrivelling in shame. Suddenly her attention is drawn back to you.

"This won't do at all," She murmors, "I would never describe this as sexual. We need you to respond!"

"E-excuse me?" You stutter.

A few of the girls take some photographs.

"This is supposed to be sexual, you have to be aroused.

Miss Desmond steps forward and places a hand just above your pubic hair.

"You need to be aroused."

The contact against your naked skin is thrilling, but public nudity keeps you flaccid.

Miss Desmond sighs, "I suppose I could help you, just to begin."

Her hand is retracted. She spits into it, then grabs the shaft of your cock and begins to stroke. The classroom is deadly silent.

As the teacher brings your erection to life, the class continues taking photographs of your nude form. Despite your embarassement you begin to respond to the hand jerking you off. Within a minute your cock is at its peak size, soon it even begins to throb.

"This could be a good opportunity," Miss Desmond muses, "What is more sexual than the point that a young man releases his essence?"

You grit your teeth. The photography continues.

Miss Desmond's hand increases speed, your manhood throbs in her soft grip. You begin to feel your balls tightening.

"Be ready, girls," your teacher orders, "I can feel he is nearly ready. This is so much easier when they are young and inexperienced. Try to capture the moment of release!"

Miss Desmond looks you in the eyes, "Are you ready?"

You nod fiercely.

She grins, "I bet you can't wait to cum in front of your hot, sexy teacher and a room full of teenage girls. You'll probably be using this moment to fuel your jerk off sessions for months!"

You let out a soft moan.

"I want you to cum, now. I wand to see your seed on the floor and in my hand. Cum!"

With a grunt you feel your balls explode. Your cock burns in the teachers grip, she squeezes you as your semen shoots out across the room.

"Impressive distance," Miss Desmond says.

She continues to jerk you, slowing as the pleasure winds down. Finally, she pulls her hand away.

Her fingers, splashed by your orgasm, are covered in your semen. Long strings hang down from her nails. She grins at you, then carefully sucks each of her fingers clean. The erotic sight brings you back to semi aroused.

"We'll, youth does have its advantages," Miss Desmond says, "Would you like to give the girls a second chance at the perfect photo finish?"
