Sex as exercise

Ashley hated gym first period. While it was usually nice to watch the other girls in her class run around and get sweaty she was also really not a fan of working out. Plus being in the locker room was always embarrassing. She had to change in a corner so none of the other girls saw how hard she would get watching them change. Though now things were about to be different. It was Ashley's world, they were just living in it. Her new body now drew eyes as she got undressed, more than a few girls shooting her appreciative glances at her new downstairs equipment. She returned a few of them with a smirk as she got into the uniform, not that she was planning on having it on for long.

"We're starting a new unit today," she said offhandedly seemingly talking to herself. "The girls in Miss. Handcock class who are over 18 are going to start a new kind of exercise program where we have sex to burn calories."

Instantly the room became a lot more vocal as the various girls started to talk about the day ahead. Most were shyly muttering with each other while some seemed to be beaming with anticipation. A lot more shot looks at her, given that she was the only futa in class the next period was going to be something special.

"Alright girls," Miss Handcock yell to get their attention. She was the perfect stereotype of a butch gym coach. Thick legs and strong arms her hair cut shorter than many guys and her face was without any makeup. Ashley considered a few changes, but figured it could wait, she wasn't going to be playing with her middle-aged teacher anyway. "I have the room set up. We're going to use the gymnastic space for this next unit. Before we head in a few ground rules. If you're not over 18 head to your assigned area for your replacement unit." A handful of girls left, some clearly relieved to be going, others clearly mad they were missing out. "Alright for the rest of you, you get to pick partners, but this isn't about hooking up so half of you get to pick, the rest just go with the girl who picks you." This got a lot of groans from the girls who were certain to not get to pick. Ashley muttered a command and ensured she got to choose. "Finally, whoever gets picked by Robbins, I'm sorry but the district didn't budget for condoms, but you still have to participate in the unit. If she gets you in trouble that's going to be your problem to deal with."

That honestly surprised Ashley but she felt a rush of blood to her cock at that announcement.

"With that settled let's go." With that final word, the gym teacher led her class into the smallish practice area set aside for gymnastics. The area had a number of air mattresses set up around the room for the girls to use for their comfort. They lined up around a small box filled with all sorts of dildos and strap-ons. Miss. Handcock quickly split the girls up into two groups. It quickly became apparent that she knew which girls would normally struggle to get picked or who would have been eager to start the lesson. Ashley couldn't help but smile at that. Handcock could be cool when she wanted.

"Now we're on a block schedule for today so you'll have 90 minutes to work out. I expect both girls to be active partners. If the girls who pick feel more comfortable using the toys they're free to do so. Otherwise use both your fingers and mouths. No complaining either, you must do this unit, I don't want any excuses. Now I'm going to pick first, then the rest of you girls can pick out your partner."

"Wait," Kim Lee said from the group of choices. "You're picking a girl?"

"Of course," Miss. Handcock told her with a lewd smirk. "I can choose to participate in class with you guys as a model of what to do. Now...Terry, you're my girl for the period."

Haley Terry jumped a little at the pronouncement. Dejected she walked over to her middle-aged gym teacher preparing mentally to spend the next hour and a half being fucked without remorse. Ashley had to credit Handcock for the choice. Haley was a mocha-skinned cheerleader who had a body like a goddess and a sour attitude. Breaking her into a cumrag would be cathartic for her teacher. The rest of the choosers seemed a bit indecisive and Ashley understood the issue, there were so many options that she was having problems picking herself.

After a moment she narrowed it down to three choices, Betty, the school's resident dancing star who had even started a local molding career. Next, there was Victoria, the star of the volleyball team and co-chair of the school's bible club. Or finally, there was Lena the local goth queen and rumored wannabe witch. All she had to do now was pick one.
