Caught My Husband Watching Yaoi

I came home early from work yesterday and walked in on my husband watching a yaoi anime. Like the two guys in the anime would full on fucking when I walked in. He turns around and sees me see him see me. He quickly turns it off and says "I can explain!" I start to walk away to the bedroom and he starts yell "It's the story line! The story line!" I dont even know what to make of this 😅
