A chance to show off what you've learned.

"I want to lick your pussy, Becky," you say.

"You mean, you don't want me to...well, you know," she says curiously.

"I do. However, I want to show you and Mrs. Sullivan what I learned from the last lesson. I was paying REALLY close attention."

"I bet you were," the Teacher says with a sly smile, "Well, Becky?"

"I've never...um, had a guy do that for me, so...um, okay."

"Good. Let's do this right then," Mrs. Sullivan says, "Excuse me a minute."

She walks over to her desk and rolls her large, desk chair over. She pushes it against the front of her desk and gestures towards you two. Not wanting to question anything right now, you both follow her direction.

She sits down in the chair and spreads her legs. Becky walks closer, but gets turned around by the Teacher. She reaches for the back of the student's mostly-off dress. She stops, however, and speaks.

"If you're going to lick her pussy, you should get her naked too."

"Yes, m'am."

You reach forward and grab the front of her dress. Becky looks at you nervously, but has a slight smile. You pull the garment down, letting the dress fall down her legs.

Becky shivers slightly, now clad only in her panties, short socks and shoes. You rub her shoulders softly, helping her relax. She smiles again and feels your hands slide down her arms. You move them to her hips and grab both sides of her panties. You look her in the eyes and she nods softly.

You pull them down to her ankles and she steps out of them. You look down at the sight of her pussy, shaved save for a patch just above the lips. She smiles as you stare at her pussy.

A pair of hands reach around and grab her hips, pulling her backwards. She falls into Mrs. Sullivan's lap. The naked Teacher reaches up and begins to fondle Becky's breasts.

"Lick her," she says, "Show her what a man can do without using his dick."

You nod and get down on your knees in front of them. You lean in and stop with your mouth mere inches from her pussy. Becky nods softly, moaning as her breasts are being played with.

You dig in, licking the outside of her pussy. You want to get it nice and moist before you go any further. She moans louder, showing appreciation for your care.

All of a sudden, Mrs. Sullivan's right hand moves down Becky's belly and to her pussy. Showing expert skill- and experience, no doubt-, she opens the girl's lips with only two fingers.

Taking the invitation, you start licking the interior of her cunt. She moans even louder, being a bit sensitive in there. You keep going, wanting to make her cum.

As the formerly-frigid student seems to be on the verge of a major orgasm, you recall Mrs. Sullivan's final lesson. Switching from your tongue to your fingers, you search for her clitoris with your free hand. Seeing the little hood, you uncover it and begin to rub the nub.

This pushes Becky over the edge and gives her the orgasm that she has desired.

"Oh shit- I'm cumming," she cries out, "I'm cumming so hard!"

She writhes against Mrs. Sullivan, shaking the chair quite hard. Thankfully, it's a big, sturdy one designed for up to a 300-lb man! The Teacher rubs one of the girl's breasts with her free hands while she rides out the orgasm.

"Th...thank you," Becky says, coming down, "That was...amazing."

"Was that your first time," you ask.

"N...no."

"But you said that you'd never had a man...ohhh, I see."

"Please...don't judge me too harshly. She was...so beautiful."

"He's not judging you harshly," Mrs. Sullivan says, interjecting, "Look at that cock of his. He's turned on."

You stand up, letting Becky see your bulge pressing against your pants. It desperately wants to be free.

"For the next lesson, we're going to cover sucking cock," she says, "Now the question is who does it. Do you want to, Becky or do I have to?"
