Your sister married a guy named Harl. Your sister introduced you to him and you got attached to him since he was so kind to you.

One night something happened to both of you that Harl took you back to his house and you both ended up sleeping together.

The next morning, Harl wakes up to the call of your sister as you were in the bathroom. Harl looks over to his side and sees that nobody is there so he thought that we dreamed about sleeping with you so he just picked up your sisters call and talked to her normally. Little did he know that it was not a dream.
