Feeling sorry for the lonely male student "Yamamoto" who stayed behind to help with the school festival preparations, his homeroom teacher "Akari" invites him for a meal. Due to a sudden, record-breaking downpour, Yamamoto finds himself unable to return home and ends up staying at Akari's place. "Don't stare too much, you perv!" Her soaked body...the lingerie peeking through her white blouse...the alluring scent of an adult woman...being alone with Akari-sensei in her room, half-naked...my heart is racing...my cock is hard! Does Yamamoto have a girlfriend? Could he be a virgin? He's so cute...I thought I was just teasing him...but Sensei...me...I can't hold back anymore! I don't care what happens anymore! Sensei! Me! I want to have sex with Akari-sensei! The virgin student goes wild with excitement, relentlessly fucking her until morning, his balls aching from the intense, non-stop action! "How many times are you going to cum?!"
