Surprisingly, Becky volunteers

"I...I'll do it, Mrs. Sullivan," Becky says softly, "He made me cum, so I...I kind of owe him one."

"That's a good attitude," she replies, "A sexual relationship must be even. If a guy is getting all of the attention, it's not fair to the woman. The same goes when it comes to a woman. Understand?"

Both of you nod. You're certainly not going to argue with her right now!

"Good. Now why don't you take his pants off. A guy likes it when you do that for him. It shows that you really want it."

Becky sits down on the ground in front of the chair first. Once she's set up, she nods and slowly moves her hand towards your waist. She looks up at you nervously and you just smile softly. She smiles back and musters up the courage to undo the button. She pulls it apart and finds the zipper, pulling it down slowly.

With growing confidence, Becky grabs the sides of your pants and slowly pulls them down. You don't try and step out of them just yet. Now only your boxer shorts stand between you and the once-shy girl.

She slowly but surely reaches for them and pulls the plaid garment down, letting gravity do the rest. Once it's freed from its cotton prison, your dick pops free. It stops inches from Becky's nose, startling her.

"Don't be afraid of it," Mrs. Sullivan says, "A dick can be your best friend. Rub it nice and slow."

She reaches up and grabs the base of your dick with one hand. She feels how warm it is. With as excited as you are, she can feel your dick pulsate. It reacts to her touch, but she doesn't let go."

"Good job. Many girls get startled by the initial reaction a dick has. Give it a good rub now."

Moving her other arm, she begins to rub your member with the free hand. She does it slowly, but gets more comfortable with it after a while.

"Very nice. Now lick the tip," Mrs. Sullivan says, "You're going to taste his pre-cum. It will get you used to his taste."

She nods and leans in to lick it. She tastes your juices, not recoiling or reacting sharply.

"It's salty," Becky says, "It's not as nice as your pussy was."

"It's just different," the Teacher says, "Now how about you put your mouth around his cock? Go on."

She takes the front of your cock in her mouth. It takes her a moment to adjust to this new sensation, but she does.

"Good. Now see how much you can take."

She takes more of your cock in her mouth, getting it about halfway down her throat before hitting real resistance.

"That's just fine," Mrs. Sullivan says, "It takes a few times to really get used to a guy's size. He's a nice, thick one too, so that is a factor as well. Now how about you just stay still and let him fuck your face. Do it nice and slow now."

Before Becky can do anything, you pull your cock back and drive it forward. You do this several more times. The young lady accepts what is happening and lets you keep doing it. You see that Mrs. Sullivan's hands have wandered down to the young lady's breasts, which is probably another factor.

"Are you going to cum soon," the Teacher asks.
