[MKON-138] My serious girlfriend was taken by a sleazy guy and I discovered she was always a freak

I thought she was my perfect, serious girlfriend. Always in her school uniform, studying hard, never giving me a second glance when I tried to get fresh. But then that sleazy guy with the slicked-back hair and the cheap cologne started hanging around. I watched from the shadows as he whispered in her ear, his hand sliding up her thigh under the desk. She blushed, but she didn’t push him away. Fuck, I should have known. She was always a dickhead freak, just waiting for the right asshole to unlock her. Now I’m hiding in the closet of this love hotel, my cock painfully hard as I watch him bury his face between her legs. She’s moaning like a whore, her skirt hiked up, her panties around her ankles. He’s fucking her raw, no condom, just like she wanted. I can see his cum dripping out of her pussy as she begs for more. This is what I get for trusting a uniform slut. She’s been creampied by a stranger, and I’m just the cuckold who gets to jerk off to the memory. Her innocent look was always a lie. She’s a cum dumpster, and I’m the fool who thought I could make her mine.
