Her brother, Eric

The next class Elizabeth had was chemistry. And she shared that with her twin brother Eric. The two were so similar that if Elizabeth had short hair some people would have trouble telling them apart. Sometimes just for fun they would wear matching clothing, Elizabeth would put her hair up in a baseball cap as would her brother, and the two would switch off. They had never done anything more silly then just play with relatives that way, so don’t get any crazy sexual ideas. Yet.

Elizabeth took a seat next to Eric. Her commando-ness was something she needed to get used to, and the lack of lunch during the lunch period was starting to get to her. She didn’t realize how hungry she was until her stomach did the third “GROWL!” just before class started.

“Jez sis, we just came from lunch. Didn’t get much to eat?” Elizabeth remembered the events just 20 minutes ago: clothing completely off, legs in the air, a face buried in her twat, a warm slimy thing swirling around her clitoris

“No, I was busy,” she murmured.

The teacher rattled something off about Hydrogen Bonds, which due to her accent came out as Hydrogen Bondage. ‘Oh don’t talk about Bondage’ Elizabeth mentally pleaded with the teacher. She didn’t know if she was into that sort of thing, but the whole Mistress M thing started by Elizabeth blurting it out, and suddenly Mistress M, her sex ed teacher, had Elizabeth wrapped around her finger.

Funny thing about twins, they sometimes had a weak psychic connection.

“Getting excited sis?” Eric broke into her thoughts.

Well yes she was. But that was beside the point. Jena pants on your crotch was something… interesting. It rubbed at her and pulled in strange ways. She felt free and naked and exhilarated but mostly terrified. What if she was still wet, would people notice? Would they think she peed her pants? They would laugh at her wouldn’t they? But… well her mistress assigned her a task and this was the only boy she liked talking to on a regular basis.

“Uh yeah, chemistry is rather interesting, isn’t it?”

“No. No it’s not.” Eirc was right. These two were not science nerds, they were English nerds. English was better in every way possible. You knew it was better since it was written with a capitol letter where all the sciences did not get that treatment. Unless they started a sentence, but that was a different discussion.

Well Elizabeth could just come out and say it, but then she might freak Eric out. I mean “hey, come have sex with my sex ed teacher!” Yeah that would work. Most of those were all old ladies and men who last had sex when the biggest risk was your reputation in public. Now Elizabeth would be applauded for having sex with her teacher, but have to worry about gonorrhea and pregnancy and threesomes and not having an orgasm and not having a condom and not having birth control and not having sexy enough underwear and being a prude and not doing butt stuff. So no, Eric would think her sex ed teacher was just some old fart being disgusting and on a very special list monitored by the government.

No, she had to figure something else out. Oh and chemistry was tough. It was all these rules of “do this, don’t do that,” but then there were 1 million exceptions! You learn all the black and white rules in a day, then spend the rest of the semester learning all the different shades of grey.

It took about 45 hours to get through chemistry. Well, more like 45 minutes. But it was not fun. And she was distracted the whole time. She had to figure out who to get her brothers penis into Mistress M’s vagina, not why water was such a good solvent! Sheesh Mrs. Z, get with the program! But the bell rang, class ended, and off they were to the next set of learning. Except Chemistry was a two period class today so they got a small break and a chance to stretch.

“So what is distracting you?”

Elizabeth didn’t know how to approach such a subject. If it was the latest fantasy novel, sure. If it was the latest episode of the arrowverse, sure. If it was why Firefly was an amazing show and died well before it’s time, sure. But…

“Remember that time we were really young and played doctor but didn’t know –“

“OK I get it.” Eric started to walk away.

‘No no no no’ Elizabeth stammered through her head as she tore off after him. “It’s not that it’s, I need to show you something.”

If you’ve ever had a sibling you know that getting them to agree to nearly anything is difficult, and that they secretly hate you while accepting you as their default best friend. So what is a brother to do when his sister is upset about something?

“OK what?” The incident he was referring to was one where their parents found the twins playing doctor, and then explained to them in remarkably calm voices that what they were doing was not appropriate for children. However, being that it was an early memory of theirs, the both found it still sore. It was a sort of code between them of ‘I’m in a compromising situation and need help.’

“I have a very strange assignment.”

Elizabeth took Eric by the hand and walked him out of class. That was not that unusual since this was the break moment, but they had minutes. Eric did not know this and had made no attempt to walk in a hurry. Elizabeth found herself dragging him along like a dog on a leash.

And then walked into Mistress M’s classroom. No one was there except for Mistress M, now fully clothed. Elizabeth didn’t know how she should feel about this. Eric, as far as she knew, was as sexually inexperienced as her. And here she was offering him to this TILF like some sort of sacrifice.
