A 'Brick shithouse' could refer to a home the lovers had built together but it has become a rotten place by her cheating on him. He's cursing. He wants her to go on cheating on him to make that other man suffer as much as he had to endure ('lay him down. lie on' or 'don't you wish you'd never met her?').
Maybe she could still be thinking she's successfully hiding her affair because she is not making a sound when she sleeps with that other man, which means she still tries to cover up.
Now I have no idea if the protagonist is a ghost or a freak watching his woman having sex. And I don't wanna think about that ;-)
