Perfect opportunity to cover anal sex!

“Hmm,” Miss Montgomery said to the class, “I really should have had Sheri turn around and show us her asshole first.” Miss Montgomery grabbed a bottle of lube that she had been given and handed it to Allen, who started to lube the fuck out of his dick. It was almost like he knew what to do…

Sheri slow fucked Allen who was resting on the desk. Her skirt was pulled up over her waist. Allen looked like someone who had a new toy to play with.

“I need another volunteer,” Miss Montogmery said. No one raised their hands. Mostly they didn’t want to have anything shoved up their bum. “Oh fine,” she said and stripped down everything below the waist.

This brought the class to a group sense of shock. It was not normal to see any of this behavior, but everyone was paying attention now! Miss Montogmery was bottomless. She also have shaved, with a nice tan line over her whole body and a clit piercing. This went over a few of their heads, after all it was a tiny little pearl just above her clit, which she nick named her pussy pearl.

Miss Montogmery turned around and bent over her desk. She then spread her ass checks apart to let everyone see her butthole.

“No this is a typical butthole, you all have one. It can be a wonderful sex act, or it can be a horrible one. It all depends on two things: how much you trust your partner and how much lube you use. There are some more subtle things but those are the two important starting points.”

Oh my god! Miss Montogmery realized that Sheri, the annoying red head, was dating Allen. It actually made a lot of sense: they were both the smartest kids, both a little nerdy, probably out casts of every social circle, so of course they would somehow gravitate to each other. Sheri trusted Allen enough to fuck her up the butt after all, that’s not something you can easily do with a stranger. OK you can, but… well it’s a possibility.

“Now if you come up here, and all of you are allowed to, you find out that my butt is rather tight.”

At first no one took her up on the offer. They just starred at the combination of Allen/Sheri butt fucking and Miss Montogmery showing everyone her asterisk shaped butthole. Then Jimmy was the first to come up and try it. She just had him use his finger at first, and he had to be careful not to just shove it in there, “just probe it a little lightly, yeah that’s it,” but it slowly began. Everyone in the class started to get up and gently probe Miss Montogmery’s butt.

OK this is turning me on a little, she thought.

“See how it’s not exactly an easy entry point?” Once the last person was done she stood back upright. “It takes some practice and patience to get in there. It can be wonderful as you will hit points you never thought you could. Sheri do you agree?”

“Oh fuck fuck fuck,” Sheri said, pushing her butt back on to Allen’s dick with enough **** to move the desk a hair or two.

“I’ll take that as a yes. Anyway where was I?” Miss Montogmery was a little turned on. And by a little I mean she needed to relieve herself… no this is a site for adults who are going to wank off to this so let’s fuck subtly: she was going to finger fuck herself when they all left. She was going to go to town on her twat, and she was going to watch these two anal fuck in her room until they were done. Or if they finished early… maybe just touch herself to some computer porn…?

Just then the bell rang, class was over.

“OK We’ll cover this more tomorrow, have a good lunch.” Miss Montgomery looked over at the couple fucking on her desk. “You two can finish if you want.”
