The affair burned hot and steady over the next couple weeks. Every text from Katsuki sent a thrill through Izuku—guilty, hungry, unstoppable. He’d summon her to his penthouse mid-morning after Kai left for work, or late afternoons when he knew her husband was stuck in meetings. They’d fuck like animals: rough, desperate, filthy. On the kitchen counter with her legs over his shoulders, pounding her pussy until she squirted across the marble. In the shower, her fat ass pressed to the glass while he took her from behind, slapping her cheeks red. On the bed, her riding him reverse, ass bouncing while he fingered her tight hole. Every time, she’d cum screaming his name, pussy clenching like it was addicted. And every time, she’d go home to Kai—sweet, oblivious Kai—with cum still leaking from her holes, whispering “I love you” while guilt gnawed at her edges. But the thrill? It only grew.

One crisp morning, her phone buzzed on the nightstand. Kai was already gone, off to his shiny new office. Izuku picked it up, heart skipping.
