Adrien wasn't sure if his senses had been deceiving him when he heard a quiet moan from behind him. It was a breathy sound that tore from the throat of whoever it was, raw with pleasure. It sent a shudder through his body, and blood rushing to his dick.

He went to whisper to Nino.

"Dude, did you here that?" he breathed.

His DJ friend nodded.

"Shit," cursed Nino. Both boys shared a glance of concurrence. They were extremely turned on. Nino poked him.

Adrien heard the moan again. He and Nino both subtly snuck glances under their arms behind them. They saw Alya, taking notes, focused and attentive as usual. She was staring intently at her notebook, mouth also saw Marinette.

Marinette's eyes were half-lidded, and her head was thrown back. She was biting her lip, trying to stifle her sounds. They could see her hips gyrating as she used the stool as a tool for pleasure, rubbing her clit on it. She was obviously enjoying the pressure and friction it placed on her sensitive bud.

Adrien felt his penis harden further. He looked down at it. He had a very large bulge, extremely noticeable. It begged to be touched, dealt with. He sighed. Adrien knew when he got horny, he was almost insatiable. His dick would throb until he found a way to mitigate the arousal. His mind tried to figure out ways to do that.

Adrien snuck his hand down his pants, unzipping his fly to grant easy access to his hard and thick member. He gasped at the feeling of his warm fingers around himself before beginning to move slowly up and down his dick. He couldn't move his wrist too much or it would be suspicious, but the languid pace was killing him. He wanted to pound his dick into his hand, jackhammer into it.

Adrien continued to tease himself, willing his hips to stay still, as he moved at a snail's pace up and down his throbbing penis. Some relief was better than none at all, he reasoned.

Adrien brought himself out of his fantasies before he could actually touch himself in class. If someone caught him, it would do horrendous damage to his reputation. His father would be extremely displeased.

Casting a glance over at Nino, he could see his friend's arousal cloud his eyes. Adrien saw Nino's eyes glaze over as his friend got lost in his own horny thoughts. The blonde dared sneak a peak down at his friend's crotch.

Nino had a sizeable erection that was already pushing at the denim prison that were his skinny jeans. Adrien felt his erection grow just looking at his friend's huge dick and toned ass. He really needed some relief, as he felt his dick strain against his pants.

Adrien looked at Marinette, who had already picked up her pace and was now furiously humping her stool, with nobody but Adrien and Nino noticing, not even Alya. Adrien watched her slam her pleasure button again and again and could barely keep the growl from escaping his throat.

Adrien turned his head back around only to see Nino's hand leave the tabletop and stray to his crotch. Nino was still trapped in his fantasy land, but he petted himself over his taut jeans, rubbing quickly up and down the surface of his length.

The bell rang, and though it was loud, Adrien could hear Marinette cry out behind him. She stood up, waddling oddly, and gathered her belongings, moving very quickly out of the room. Adrien looked down at the stool. There was a big patch of wetness on it- she had been very aroused. And she had come in her panties.

Adrien poked Nino, who took his hand off his dick. By unspoken agreement, the boys both ran towards the gym. There weren't any classes in the gym during second period and there were some rooms there that they could use to deal with their little (actually, big) problems. Adrien had thrown all concerns about his reputation out the window for the moment, sure that his father would prefer him to cut a class than whip out his dick and start masturbating it in front of the entire class. He and Nino shuffled out of the room, binders covering their erections. Adrien really wanted to fuck Marinette right now. Her breathy little whimpers had kept blood pumping to his dick for the last half of class, with nothing he could do about it.

The boys were about to burst into the health classroom adjacent to the gym when they heard voices.

"Marinette, you really need to work on your self control," the boys heard the voice of Alya admonish. So she had noticed her friend's rather erratic behavior.

"I know, it's just…"

Adrien could picture Alya motioning for her to continue.

"Adrien and Nino kept touching, and whispering, and then my mind started to wander. I pictured them getting each other off in class, and then taking it to the bathroom where they fucked and sucked each other."

Alya let out a groan herself. "Damn Marinette, that's hot. I think I need to jill off after hearing that."The boys repositioned themselves near the door, which was slightly ajar. They had a clear view of Marinette and Alya sitting on the desks.

Alya hiked up her skirt, revealing a glistening pussy. The boys both unzipped their pants and pulled down their boxers, dicks standing proudly and nakedly. They were so horny they didn't care that they were in the hallway. They started fucking their hands slowly as Alya rubbed circles around her clit, moaning. They just had to pick up the tempo once Marinette started grinding on a chair nearby, watching her friend massage her juices over her clitoris. Alya stuck a finger into her pussy and moaned very loudly. The sound went straight to the boys' dicks.

"Fuck," whispered Nino, and he came all over the hallway floor, dick spurting thick ropes of sticky white liquid all over the place. Adrien was still beating his dick.

"Nino," Adrien whispered. "I need my dick to feel like it's in her tight, hot snatch. Oh, god, I need it so bad."

Nino nodded as his dick started to rise again. Nino kneeled down in the pool of his still-warm cum, facing Adrien's massive erection. He licked his lips and engulfed Adrien's dick with his warm mouth, slowly sucking up and down. Nino's own dick hardened painfully, but he ignored it, focusing on giving Adrien's dick a thorough sucking.

Adrien imagined plunging his dick into Marinette, all thoughts of Alya abandoned. He started to fuck Nino's mouth. Nino almost gagged, but he conquered the reflex and took Adrien's mouth-fucking. Adrien imagined pounding Marinette's tight pussy from behind, making her scream with pleasure. This image, combined with Nino's skillfull deep-throating, had thick ropes of cum shooting out of Adrien's dick in no time. Nino swallowed it like a champ.

Both boys panted as they peeked in the room again. Alya lay spread eagle on the ground. Marinette's perky ass, with only a lace thong covering it, was sticking up in the air as she was on all fours, eating out her friend's pussy. Her head was covered by Alya's skirt.

Adrien decided enough was enough. He crept into the room and plunged his dick into Marinette's pussy. She cried out in shock, pain, and pleasure. Adrien covered her eyes so she couldn't see who it was. She started moving up and down on his dick like the little slut she was.

Meanwhile, Nino had taken over licking Alya's pussy, and her head was thrown back, eyes closed. She came like a waterfall, gushing sticky fluid all over Nino's face and into his waiting mouth. She didn't know that the person who was eating her pussy out so well was a boy until she felt the tip of his dick prod at her entrance. She and Marinette often helped each other take care of their problems, and Nino was so good at eating pussy she had assumed it was Marinette. Alya plunged down on Nino's dick as a reward for giving her such a good orgasm.

They all fucked in earnest, the two couples next to each other screaming and moaning. They'd never fucked or been fucked so good in their lives. Adrien and Nino made eye contact as they fucked the two girls, and that was enough for them to realize they needed to cum, and soon.

Adrien reached down to pinch Marinette's clit. That was enough for her; her pussy walls clenched his dick tightly as her fluids cascaded over his rock hard dick. Nino bent over and licked Alya's clit. He felt his tongue lick his own dick, too. He and Alya came at the same time, the warm heat of Nino's tongue being too much for both of them.

Adrien pulled out and came in Marinette's hair, making it so dirty and stick with his ropes of cum. The four all lay there for a while, panting hard. That had been the best time of their lives.
