This is Chapter Four of The Lessons. If you haven't already done so, you are encouraged to read the earlier chapters; otherwise, aspects of the story might not be understandable. Readers who find this chapter enjoyable are obviously encouraged to read the subsequent chapter.
In any case, please do provide feedback. There are obvious sequels to this initial series. I have made outlines for some of them. I will be very happy to write them, but there won't be much point if there is inadequate interest. I would also like to hear your suggestions for how to improve the series.
Finally, please do vote; especially if you like it! I must admit that getting good votes can be the best form of encouragement (I didn't realize how long it would take to do this, particularly when it came to the copyediting). But, even if you don't, I do hope you enjoy it!

The following afternoon the students arrived on time, and it was evident that most had done their homework. Discipline did appear to be improving. Sara was particularly pleased to come to class. When she had returned home the previous afternoon she went straight to her bedroom. She locked the door so that her parents would not come in unexpectedly, and climbed onto the bed. She got onto her knees and bent over so that her bottom was sticking up into the air. She flipped her skirt over her back and pulled down her panties. The cork was still nicely lodged in her asshole. Mr. Peters had called it an anus, but Sara kept thinking about it as an asshole the rest of the day. It seemed more sexy to call it an asshole, at least when it has a cork stuck in it.
She carefully felt the outline of the cork. It was quite a big cork and her asshole felt rather uncomfortable with such a large object lodged inside, but the discomfort was also pleasing in an odd sort of way. She felt her pussy, which was very wet, even a bit swollen. She began to squeeze and stroke her cunt lips, feeling the moisture increase and spread across her young pussy. She began to massage her clitoris with her fingers, circling around and around the clit, at times as well squeezing and pressing it.
Sara had masturbated before, but had always done so lying on her back and under the blankets. She now found that it was much more dirty and exciting to do it right out in the open, her bottom stuck up in the air for all to see. She in fact imagined that she was doing this in front of the class, exposing her corked butt and wet pussy to all of the students. She had been terribly humiliated to have to show herself this way in class, but now that she was by herself at home, she could safely enjoy the fantasy. She liked thinking about all the students staring at her, shocked at how she was making such an obscene spectacle. She thought about the boys getting all excited at her display. Imagining them playing with themselves as they stared at her upraised cunny got her more excited. She even imagined that it was Mr. Peters who was fondling and playing with her juicy, swollen pussy. Mr. Peters would never do such a thing. He was her teacher, but that made the thought of him doing so all the more stimulating. She increased the pressure and speed of her manipulations. She groaned softly into the soft, thick bedcovers, hoping that her parents could not hear anything if they happened to walk by her room. Her bottom began to wiggle in the air, circling in a direction complementary to her fingers. She inserted two of her fingers into her cunt, using the palm of her hand to keep pressure on her clit. She grabbed hold of the coverlet with her other hand.
She manipulated her fingers in and out of her pussy. The entrance was very tight but she was also so very wet that insertion was not at all difficult. Her pussy began to make squishy sounds as her fingers plunged in and out. She grew a bit more concerned that her parents might hear something, but even that now was part of her excitement. She thought about her father walking in while her butt was in the air, fiercely masturbating herself to an orgasm. She knew her dad would be angry, but he might also find it exciting. Maybe she shouldn't have locked the door after all, she thought.
She considered getting up to unlock the door, just to add some risk to her fun, but she didn't want to stop playing with herself. She knew it would not take long, as she had been thinking about this all afternoon and she wanted so much to release her sexual tension. She began to thrust her bottom to help push her fingers deeper into her pussy.
She felt so dirty and naughty. She knew she must look like a very smutty girl, her panties down, bottom up in the air, thrusting wickedly into her fingers. Her breathing became heavier and heavier, her thrusts growing in speed and abandon. She began to grunt and groan more loudly into the bed, grasping her cunt hard with her hand as she stuck even another finger deep into her pussy.
She was also squeezing hard onto the cork with the lips of her asshole, enjoying the full, stuffed sensation of the large cork crammed into her butt. She imagined it was more than just a cork. She imagined that Mr. Peters had required her to stay after class so that he could adequately punish her, and punish her in a way that was even more personal and intimate than what had occurred during class.
She whispered into the coverlet, "Mr. Peters, harder, harder; fuck me so hard Mr. Peters, I am such a bad girl. Fuck my butt Mr. Peters. You have such a big cock, fuck my little bottom with your cock." She imagined Mr. Peters tossing her skirt over her back, leaning over her and ramming his big hard cock deep into her ass as he played with her wet cunt with his fingers. He was so big that she could hardly take it but she had no choice but to comply. He was her teacher and she could not do anything about it. She had to submissively keep her ass up in the air while he fucked her again and again. "Mr. Peters," she squealed into the coverlet, "You're too big, it's too big for me, I don't know if I can take any more" and she then exploded in her orgasm. Her whole body shuddered with excitement, and she pressed down heavily on the cork as if she had a huge turd that had to be released. The cork popped from her butt as if it burst from a champagne bottle and shot across the bed onto the floor. Her body froze in place as she enjoyed the waves of pleasure and the release of tension.
It was a few minutes before she relaxed. She slowly lowered her bottom to the bed and covered herself with the coverlet. She was now very grateful to Mr. Peters for his firm discipline.
