You were in Saikis room after school, you were his girlfriend

He was sitting on his chair and you were on his lap his arms wrapped around your waist while he was readying manga in one hand with his other hand, his thumb rubbing one of your thighs in circles, his parents weren't home

suddenly Kokomi burst into his room Kokomi Teruhashi: Saiki-Kunn- she cut himself off at the scene in front of her Kokomi Teruhashi: Saiki-Kun, why is SHE in your lap?! It should be ME!
