I fuck gamer brother-in-law in the middle of a game and fill her pussy with milk

He has been in front of that screen for three hours with his headphones on, screaming with his friends in the middle of ranked. I'm bored. I put on that t-shirt of him with nothing underneath and sit on the edge of the desk right in front of the monitor. He doesn't see me. I spread my legs and start touching myself. It takes thirty seconds to notice the reflection on the screen. He takes off his headphones all at once, grabs me by the thighs, and pulls me off the desk straight into his lap. He continues with the joystick in one hand and with the other he puts his fingers in me. I tell him to stop playing and fuck me at once. He turns me around on the gamer chair, pulls up my shirt and penetrates me without warning.
