Mommy Eavesdrops on Taboo Roleplay

Ever since your girlfriend started getting into the taboo roleplay stuff, you can't get enough of her. I mean, if you can't fuck your mom, the next best thing is fucking someone else while you pretend their your mom, right? You have to be sneaky, though, still living at home, and with your mom's silly rules about girls in your bedroom. But she's got a predictable work schedule. Or, so you thought. You could have sworn she said she was going in to work in the morning, but then all of a sudden, right after busting a nut inside your girlfriend while she called herself mommy and begged for your cum in her, you hear a knock at your bedroom door...your mother, standing there, has heard everything. And she wants to talk. About everything.
