I remember seeing a hentai where the guy was watching a porno while the girl was"sleeping" in the bed next to him. He knows she is not asleep so he starts teasing her to see how long it will take for her to stop pretending to be asleep.
She wanted him to have sex with her while he thought that she was asleep so she could use that to blackmail him, but because he knew she was awake he used that to cancel her intention out.
It also skipped to another guy and girl after they were done.
Pic not related btw ( I think atleast)
I dont know it the girl is related in any way to him btw
