Would anyone like to feel an erect penis?

"Would anyone like to feel an erect penis?" Diana asks the class.

A few of the girls look at each other, but no one volunteers.

"I'm sorry," Diana says, "I know it's a little strange to touch someone else's penis, but it's important for you to know how it feels. If no one wants to touch it, how else will you know?"

"I will," one of the girls says. You look over and find that it's a blonde girl. You had noticed her before, and she is pretty hot.

"Ok, Grace, you can touch it," Diana says, and Grace steps up for a better view of your erection. Her blonde hair is pulled back into a ponytail and her breasts under her checkered blouse are still pointed at you like a divining rod. She reaches out her hand and rests her fingertips on your cock.

"Can you feel it getting harder?" Diana asks.

"Yes," Grace says, looking down at your cock with a cute smile, "but it feels weird. Is it supposed to feel like this?"

"Yes. It's called a throbbing erection. It happens when blood rushes into the penis to make it hard. You can feel it throb in your hand."

"Can I do it again?" asks Grace.

"Sure. See how hard it gets."

Grace strokes your cock with her fingertips and you can feel it starting to throb harder, aching with pleasure and desire. You can feel the blood rushing into your shaft, hardening it. "It's getting hard. I can feel it getting hard in my hand," she says.

"Would anyone else like to feel it?" Diana asks.

The girls whisper for a moment, and then one of them, a fit, sporty brunette with a ponytail, says "I will."

"Thanks Tanya," Grace says, and steps aside to let Tanya feel your throbbing erection.

Tanya steps up and rests her fingers on your erection.

"Wow," she says, "so hard. What do I do to make it feel good for him?"

"You can wrap your hand around it, and move the skin up and down a little."

Tanya slides her hand up and down around your shaft, and you moan slightly, pushing into her grip. It feels incredible.

"I want to feel it again," Grace says.

"Sure," Tanya says, "I don't mind."

Grace puts her hand back on your cock and you feel yourself starting to get hard again. The two girls feel you off while you blush and moan. Occasionally, they look at each other and giggle. You can feel your cock getting harder and harder, and harder. The throbbing is more intense than you can remember. You start to moan, one hand on the back of Grace's chair, the other on Tanya's shoulder.

"Ok, I think that's enough for now girls," Diana says.
