...Principal Keith shows up.

"Oh god yes Miss Long." Gabriel said as he fidgeted with is phone. With a feeling of pride Miss Long smiles, glad to think she gave a good lesson.

Then Gabriel pulled his pants up hurriedly. He needed to get out of there and tell everyone what had happened. Thanks to his phone he could even show them.

Gabriel left just as Miss Long was buttoning up her blouse.

Principal Keith walked in the door.

"Miss Long." He said in his usual administrative voice.

"Oh Principal Keith!" Miss Long smiled as she brushed aside a piece of stray hair that had gotten displaced in her lesson.

"I received your email Miss Long, and I am so sorry to hear of your condition. I know AGS is pretty serious." He placed a hand on his shoulder.

"Thank you Mr. Keith," she said trying to put on a brave face "I know it will be hard, but I am sure I can work through it. I am sorry you just missed the first lesson of the new class you wanted me to teach."

"What new class?" He asked concerned.

"The Sex Education class you told me I was to teach. Gabriel gave me your note." She fiddled around on her desk and found the note and handed it to him.

"I just showed him an example of oral sex," Miss Long smiled "He was very eager to learn. I think that hands on teaching for sex education is really the future."

"I...didn't writ-I mean... I am glad you had a good lesson." He pondered for a moment. He had come here to test and see if she really had AGS and it seemed like she did. He hired her years ago and she still looked amazing. Her interview went well but he could never get over those legs of hers.

"In fact," he said "I think you should show me exactly how you do this."

He walked to the door and locked it.

"Think of this as one of your yearly observations, unannounced." He smiled.

"Oh! Okay." Miss Long said, knowing she had to get her observations out of the way for the year anyway.

"Well Gabriel had asked me to show him oral sex. Would you like the same demonstration?" She inquired.

"Ummm Yes that sounds excellent. Mind if I sit down?" He moved over toward her desk chair.

"No problem, there are plenty of ways for a woman to preform fellatio on a man. Though it will be easier if you take off your pants." She said as she neared him once he was settled in. He was a tall man, slightly overweight and balding in his mid to late 40's.

"You really do have AGS don't you?" he laughed in his head as he obliged her and slid his pants down, along with his blue briefs.

"I do Mr. Keith, but don't worry it won't affect my teaching. Alright take a seat and get ready for the lesson." Miss Long said gingerly as she moved in front of him.

"One of the most popular forms of sex today is 'oral sex' especially among youth who are trying to avoid pregnancy." Miss Long lectured as she moved to her knees. His cock was growing steadily. He wasn't exactly long, but he had some serious girth to him. His balls were rather unkempt with bushy hair, though he was not woolly mammoth.

She took his growing cock in her hand and began to jerk it off slowly.

"Sometimes manual stimulation is required before oral sex can occur." She said, jerking his cock off mechanically, as if getting ready for the next step in a science lab experiment.

"Mhmmmmmm" he moaned as he felt her soft hands caress his cock. It was nearly hard now and he couldn't believe the odds of having his hottest teacher get AGS.

"I think your penis is ready." Miss Long said rhetorically. Just as Mr. Keith was about to answer she swept in and quickly took him in her mouth.

"Oh ooooooh yessssssss" he said as he felt her mouth working his shaft. He looked down and saw her brunette head bobbing on his dick. He wanted to cum. His wife hadn't sucked him off in ages and he had dreamed about something like this happening. He resisted the temptation to cum right away, his manhood wouldn't let him.

Miss Long sucked faster fighting with the girth of his cock to keep him all inside of her mouth. She moved her hands to his thighs and rubbed lightly along them. His cock throbbed and he moaned as she did this.

"Uhmmmmmm Tell...me....Miss Long...have you..." he fought with the words and held himself back from cumming "...have you done this today before."

"Only to Gabriel." She pulled her mouth off his cock for a moment to answer.

"I see, well you are doing an excellent job Miss Long I think you should teach this class all day rather than just for in the morning time." he regained some stamina as they talked.

"I certainly can if that's what is needed." She said before putting Mr. Keith's cock back in her mouth again. She sucked in quick strokes near the head of his dick. He looked down her blouse and he moaned as she tightened her lips harder preparing him to cum. She was sucking cock like a pro he thought. He could use this every day.

"Miss...Long." He said nearly about to cum. She pulled off just in time.

"Yes sir?" she said her mouth just next to his cock's head.

"I think you need to come by every morning before first period and show me some of your lessons." He said breathing as sigh as he fought to regain his stamina, he couldn't cum as fast as some fucking school boy.

"Am I in trouble Mr. Keith?" She asked worried.

"Oh no--its just that I want to be part of the collaboration going on with this new class of yours." He smiled.

"Of course!" Miss Long said "That's a great idea. I know the central office really wants us to collaborate with fellow staff."

"Alright Miss Long," he said feigning concern "I am sorry to have disturbed your lesson--please continue."

She put his head back into her mouth and sucked hard, this time slowly though. She wanted to mix it up so he could learn through different methods.

"Oh my Miss Long....." he moaned as his cock stretched her mouth. She took his girth in, though like a champ. Tightly she closed her soft lips on his shaft and pulled back to his head, then down again. Harder with each bob of he head she sucked harder. Finally she caressed his balls with one hand as she steadied his shaft with her other hand. He wasn't quite long enough for proper strokes but he wanted to steady it since she knew the inevitable was about to occur, she could taste some precum and prepared herself.

Fortunately for Miss Long she was prepared for his cum, having felt his balls contract slightly and his head expand in her warm mouth. Mr. Keith didn't even tell her he was cumming.

"Gughghghghghghhhhhhhhhh" He writhed in the chair, gripping the armrests tightly as he shot his cum deep inside her mouth. Miss Long kept her mouth just as his head, the most sensitive part, and sucked in short quick movements as each of his warm stringy jets filled her mouth.

"Miss....Long....that was....an excellent....lesson." He said panting. He had not gotten a blowjob like that in decades.

She pulled off his cock and looked up at him.

"Well I am certainly glad you enjoyed it!" She smiled.

"I think you should report to my office during your planning so we can work on some further lesson as well Miss Long."

"I am sure I could swing by." she said as she stood up.

Then...
