Give the girls a chance.

"Now that I've shown you how to touch the shaft, I'll give you ladies a chance to try. Then we can play with the head of his penis, which is even more sensitive."

As she talks, much to your dismay, Diana releases her hold on your cock. The girls start gathering around. The blonde, introduced as Grace, is first to wrap her hands around your shaft, giving it three quick tugs that you barely have time to thrust into. "I can feel his whole penis pulse," she murmurs thoughtfully, then goes back to her notes.

Then, the girl with the long black hair, Samantha, grabs you and starts stroking up and down more gently, smiling as you sigh and push into her hand. Pretty soon, several more girls join, sometimes taking turns, other times stroking your cock all at the same time.

As you look down at the small crowd of thoughtful, nervous, and mischievous faces, soft hands caressing your sex endlessly, you think you're in heaven. The only thing stopping you from cumming on the spot as the slightly distracting flow of having differing hands stroking in different directions.

"Ok girls," Diana interrupts, "Hands off, I want a volunteer."

The girls pull away giggling and whispering. You're ragingly hard.

"Sophia, you haven't touched him yet," Diana says, "Want to learn how to touch one of his most sensitive areas?"

You look over to Sophia, noticing that she's buttoned her shirt back up. She's still in her white panties though, to your delight. She looks helplessly at Diana, then shrugs, "Sure, I've already undressed for him!"

"I want you to take your thumb and forefinger, like this, and light grasp underneath the head of his penis, just where the shaft meets the head."

Sophia scoots in, looking at your a little nervously. She reaches out, hesitates for a moment, the wraps her fingers around your cockhead. You swell against her as a warmth of pleasure spreads upward.

"Now," Diana instructed, "gently squeeze upwards, as if, pardon the analogy Joe, as if you were trying to milk his penis."

Sophia's brow furrowed in concentration as her fingers closed tighter around your cock and started dragging upward. You let out a raspy gasp as the pleasure shoots through your body like a lightning bolt. She pulls her hand away as if burned.

"No no no," you say, "Sorry, that just felt really good!"

"Seriously?" Said Sophia, concerned, "It sounded like you were in pain."

"No, just started by how good it felt. You can keep going if you want."
