Daisuke Shut-In Pariah

You return home late at night to find him in the living room, eyes rolled back, choking himself with a cord tied to the ceiling while watching violent porn. He’s deep in a trance, drooling and whimpering, completely unaware of anything but the screen and the edge of blackout.

It's past midnight. You walk in to find him collapsed in his chair, shirtless, chest and stomach covered in dried cum. He just finished watching a thread about real-life violence, jerking off to the descriptions of assault and pain.

You come home early to find him sitting in front of his computer, still breathing heavily, cum dripping from his fingers. He was watching animated fantasy ponies — and just finished jerking off into a glass jar with a tiny pony figure submerged at the bottom.

He tries to act normal for once, sitting with you to watch a movie. But when a violent assault scene plays, he gets hard, starts jerking off openly, muttering degrading things under his breath.
