Your teacher, who in this reality you call by her first name, Clara, walks with you to the gymnasium where the other students in this period were lined up, being given a rundown of today's regiment. "Today will be a a bit of endurance training." The gym teacher states. "If things get too difficult, feel free to take a break and spot for your partner." "I wonder which should be the best forms to perform today." Your sex-ed teacher, Clara wonders aloud. "Aha, I know just the thing." She says triumphantly. Clara walks over to the gym teacher and whispers in his ear, to which he then nods. What your teacher/mate has in mind is to go back to the locker room and change into a different outfit. "While this will be for your health," Clara explains while she gets changed with you. "It doesn't mean we can't have some fun with it." She coos.
When the two of you get back to the gym, it is clear what your sexy teacher has decided to change into; Clara is now wearing a black one piece suit made of a soft leather. A large zipper runs up the back of it, and there are 3 inch heels built into the area where her feet are. Now, you were still inside the constraining outfit. She wore a bra and thong to help secure you ever so slightly, but within such tight fabric, you were basically stuck to her. Not to also mention that it was stuffy, hot and hard to breathe. 'This is so fucking kinky....I love it.' You quietly moan, barely enough for even Clara to hear you. With your head between her breasts and you dick pushed deep into her pussy, you can't help but thrust your hips enough so that you can get some amazing sensations down below. "I'm going to keep coming inside you and filling you up!" You groan and blow another load in your teacher. "Easy there, cutie. We still have to go through this class, y'know." She replies, blushing from being creampied again.
Clara begins some stretches, this didn't last long; she just wanted to make sure her body was limber and you were still horny. "How about some pushups first?" She suggests, getting on her hands and toes. Clara is surprisingly handling pushing her body up and down, even with your added weight. The only one with the problem is you; each push moves your dick around slightly, making Clara's pussy squeeze it subconsciously. "What's the point of this exactly?" You ask as you can feel your teacher start to sweat from the workout, making the inside of the suit even stuffier. "This is endurance training, my love." She states, her calling you her love strikes a chord with you. Clara continues, "We are training how much you can endure in sex; the longer you can last before succumbing to exhaustion is a necessity in coitus." "Wait, but you;re the only one I'm ever going to have sex with." You note the slight absurdity of this reality. "That's alright, honey. You'll learn to become even better as we always make love."
"Ngh, fuck!" You shout, and come so much into her pussy; the slight asphyxiation you were beginning to have made the process feel incredible. "Aaaah, yes!!!" She moans loudly, causing other boys in the gymnasium to turn their heads and envy you. "I love when your fluids spray into me! And you're still conscious, well done." She compliments, as she stands back up. The warm fluid in her pussy shifts as her position changes, making her reel from the pleasure. The next task Clara sets to is grabbing onto one of the climbing ropes hanging from the ceiling; despite being penetrated and wearing a suit with tall heels, she is able to climb all the way to the top. Only to then let go of her hands and fall backwards; her clears still wrapped around the rope, then she grabbed it again. This put the both of you hanging upside down high in the air, gravity pulled you down more, pushing your dick deep into Clara's full pussy.
"And what's this for?" You ask for explanation. "Uhm...seeing how well you are under pressure." She hesitantly states; at this point, you are sure she just wants to have sex in weird scenarios. "Well, if you insist Clara." You say and begin shaking your hips, twisting your slick rod around inside her pussy. "Ooooh, oh fuck...." She curses, struggling to hold onto the rope. "You are too fucking good at this!" This gave you a much needed confidence boost, speeding up your thrusts in an attempt to please your mate. Hanging from the air by a rope, you felt like the two of you were mating like feral primates, just having straight up bestial sex in an attempt at impregnation. "Here comes another load of semen, you sexy thing." You say, cumming once, twice, three times in a row. "Aaaah, yes." She moans, slowly traversing to the ground; laying flat on her back once there. "I could just take a nap in here..." You joke.
"Well, let's get to the locker room and clean ourselves up." Clara states, considering your gym class done. "Mmhm." You reply. Once in the solice of the changing room, the two of you are faced with a problem; apparently during gym class, the zipper of Clara's suit had broken off, leaving it stuck on her with you inside. "Uh, sweetie? We had a slight wardrobe malfunction here...." She informs you. "I don't mind at this point." You reply, having gotten used to the stuffy, sweaty interior of the suit. "It's so nice in here, you smell lovely." Clara is slightly taken aback by this statement, but does not mind. She grabs her breasts and moves them around, effectively rubbing your head that was still between her cleavage. "If you're ok with this, let's just get you ready for your next class then." She says, before walking out of the locker room.
