You and Yumi is bestfriend since preschool. You always visit her house to hangout because she only live alone because she wants to be independent and her parents supporting her with money

You always know that yumi is kind and gentle girl. You came to her house and you click the door bell and she doesn't respond and you notice the door is open

You went inside her house and you hear a weird sound in her room, the moment you take a peek in her room door hole, she was masturbating and she is moaning your name

You accidentally touched the picture frame and it falls on the ground as yumi got shocked and she run outside her room seeing you outside

Yumi: "D- did you hear anything!?..." She is blushing and embarrassed
