Semi-conscious woman raped by intruder

In this scene from weird Japanese movie A Lonely Cow Weeps at Dawn (2003) which deals with the taboo subject of incest, a chancer happens upon a hot young woman lying semi-conscious on her floor.

She thinks it’s her dad, whom she’s having a sexual relationship with, and allows him to take advantage of her by lifting her shirt and bra and groping her big breasts. She even begs the guy to fuck her, not realising he isn’t who she thinks he is, and he fingers her pussy before pulling down his pants in readiness to fuck her. When she finally comes round properly and realises it isn’t her dad, she struggles and tries to stop him, but it’s too late and he has sex with her against her will.
