Yes please.

"Ok, that's fine. Do whatever you want." You try to play it cool.

The girls in the class are now approaching your throbbing erection. Some of them are kneeling down to get a better look, as Diana starts to stroke you even faster.

"Girls," Diana says, "I want you to touch Joe's penis. He's really turned on by Sophia, so he's practically bursting with blood. Feel his shaft, touching the skin and the throb of his blood pumping inside of him."

A couple girls are still too shocked, and Diana lets go of you, encourages them to at least rub their hands along your shaft. A delicate touch, with a few giggles, and you feel the warmth of their hands. Then one girl reaches out and grabs you.

"Wow, his penis is so hard, " she says.

Another girl reaches out and grabs your cock. "It's so heavy," she says.

"Are you ok, Joe?" Diana asks again.

"Yeah, I'm fine," you say, barely able to concentrate on Diana's words.

You look down as hands slide up and down your shaft. It feels amazing, but you're still so focused on Sophia that you barely notice. Just the sight of her breasts, slightly reddened from your caress, is firing off your arousal. You feel sensitive to touch, every movement of your shaft electrifying you.

"Ok class, would anyone like to try tasting him?"

Grace, a full-breasted blonde who has been taking a lot of notes through this whole class, raises her hand. "Why would we taste him," she asks.

Diana smiles, "Well, it can be very pleasurable for a man for to have a tongue on his penis."

Diana pulls you closer to her, and then sticks out her tongue towards your shaft. "Girls, when the penis enters the mouth, it touches the taste buds in the tongue. Those taste buds are called papillae. Can I demonstrate?" she asks, drawing her tongue along your cock.
