Tatiana Vasilievna droned on about the Pythagorean theorem, but Egor's mind was elsewhere. Specifically, it was on Sima's luscious derriere, which was currently on display as she leaned over her desk to copy notes from the board. The sight of her curves had Egor shifting uncomfortably in his seat, his mind wandering to thoughts of running his hands over her smooth skin.
He shook his head, trying to focus on the lesson, but it was no use. He couldn't get Sima out of his head. He remembered the time he had jerked off while thinking about her, his body shuddering with pleasure as he imagined her moans and gasps. He felt his dick twitch in his pants at the memory, and he bit back a groan.
During a break in the lesson, Egor found himself accidentally brushing past Sima's ass with his thigh as he walked to the wastebasket. He felt his cock stiffen immediately at the contact, and he couldn't help but glance over at Sima to see if she had noticed.
Sima, of course, had noticed. She smirked at him, her eyes glinting with mischief and desire. Egor felt his face heat up, but he couldn't help but feel a thrill at being caught. Sima was a bold, confident woman, and Egor found himself drawn to her like a moth to a flame.
Without a word, Sima led him to the single-stall bathroom, her hips swaying enticingly as she walked. Egor's heart raced as he followed her, his mind filled with thoughts of what was about to happen.
Once inside the cramped space, Sima pressed her body against Egor's, her curves molding to his hardness. She whispered playful insults in his ear, teasing him for being so easily aroused by her.
"Such a simple touch, and you're already hard for me," she purred, her breath hot against his ear. "You're so predictable, Egor."
Egor couldn't help but respond, his hands roaming over Sima's body, feeling the heat radiating from her skin. He traced his fingers over her curves, his mind filled with thoughts of stripping her bare and exploring every inch of her.
Suddenly, the bathroom door swung open, and the class's monitor, Natalya Viktorovna, walked in. She saw the two of them in a passionate embrace and raised an eyebrow.
"Well, well, well," she said, a smirk on her face. "What do we have here?"
Sima, never one to back down, grinned at Natalya and suggested a threesome. Natalya, intrigued and turned on by Sima's boldness, agreed. She pulled out a strap-on and ordered Egor and Sima to get on their knees.
The three of them explored each other's bodies, their moans and laughter filling the small bathroom. Egor found himself lost in the moment, his mind filled with pleasure as he explored Sima and Natalya's curves.
As they reached their climax, Egor couldn't help but feel grateful for the accidental brush of Sima's ass that started it all. It was a moment he would never forget, a moment that would forever be etched in his mind as the beginning of his exploration of the geometry of desire.
