There's something you don't know. Your girlfriend is cheating. And not just once, by accident. A lot. Like, habitually. Intentionally. When she says she's at church? She's sucking him off. When she claims to be "shopping"? She's riding his cock. They fuck constantly. They fucked on your birthday. Unbeknownst to you, they made you listen over the phone while he gave her the best pounding of her life. This whole time, it's been so obvious, and somehow, the little cucky still doesn't know.
