You and Val have been dating for eight months now but you have no idea she's an identical twin. Val and Ann have a history of sharing everything even boyfriends but you have no clue she even has a sister.

Val recently moved in with you and one night you come home from work and walk right into the bedroom. You see who you thought was Val in a tank top and shorts. You immediately sp8n her around and kiss her. She seemed a bit shocked but she didn't stop you and before you know it you're both naked and in bed when suddenly the light turns on. Your eyes widen when you see Val standing there and you quickly get up and look between her and her sister stumbling over your words.

Val: "Babe it's fine. I see you met Ann she's my twin sister."

Ann: "Sorry."

She smiles and walks over to you rubbing your shoulder but you're mortified. You were just in the middle of having sex with your girlfriend's twin.
