Just as she finished her sentence, Alya and Marinette heard a pen rolling on a piece of paper, twice. For a dozen minutes they helped the crew from inside the toilet, mainly with the phone and it’s feature, the connection with the motion captor and a few more things. Lastly, someone slid the two collars under the door and the suckers put them on. Just a *click* and with no key available, they would stay there for a while. They did some last checks of the collars strength. It ended up on barely painful, it wasn’t a torture device after all.

Soon, everybody left the room, but them. The two girls looked at each other, as the reality of the situation slowly swept in. They didn’t talk, didn’t chat, didn’t laugh. They weren’t there for that. The two of them simply waited. Marinette heard their teacher, or former teacher, said they would be available starting 10 AM, for the first recess. It really itched, they wanted to break to boredom, the room was so tiny their bare skins were constantly in contact, they needed to interact and say something. But no. They weren’t really living being at this point, they had to fulfill their duty before anything. With their sheer willpower they managed to wait still until the bell rang 10 AM.

Seconds later, two large dicks entered the glory holes. They had to leave class early. Marinette thought she could recognise to whom the one before her eyes belonged to. But she refused, it wasn’t her job, she would simply take it in her mouth and suck it. She pushed herself to wrap her lips around the cock in front of her. With no prior knowledge or experience, she did her best. Suction sounds filled the room, Alya started sucking just at the same time. There wasn’t a lot of room around them, so they had to press their bare ass against each other’s to stand at the right height.

Marinette did her absolute best she forgo everything and simply focused on pleasing the cock in her mouth. It took about a minutes for it to shoot a load of cum down her throat, she took it firmly and swallowed it without changing her pace, it took her a lot of strength, but she didn’t care, only the dick mattered, it was her duty. She didn’t move once the cock had came, it was only its owner that could decide when he was done, he slid it off once Marinette licking it it clean. Almost right away, another took it’s place, and Marinette did just the same, again and again. Until the end of the recess, one cock every now and then during the next hours, and another rush during lunch break, then a steady flow the afternoon and a semi rush from 5PM to 10PM with one cock every few minutes from the boarders.

During the evening, with so many cocks and a bit of time in between, they decided to train. Marinette tried a few things when handling the cock, angles, licks, using her face. And so on for a few hours. Alya had an idea, since they weren’t as much dicks than during the rush, the two of them could focus on one. First they shared one, each of them on both side, then one for the shaft the other for the tip. Next they tried helping each other, Alya grabbed Marinette’s head and pushed it up and down the cock, repeatedly, fast, and violently, with no regard for Marinette’s safety or well-being, not that Marinette cared either. Next, Alya wanted to try taking the dick as much as possible, she pressed her face against the glory hole and guided the cock deep into her throat. Meanwhile, Marinette laid against the opposing wall and used it as support to sink her feet into Alya and push her into the wall to take even more of the cock. With one foot pushing on her ass and the other at the base of her Neck, Alya was literally shoved into the wall, her face was scrunched against the wall, along with her boob and the rest of her body. The dick quickly came, but once again, they didn’t stop until its owner pulled out.
