[ENGLISH-SUBTITLE] MILK-243 "Hey, do you want to watch some adult videos together?" I suddenly lost my virginity while watching some adult videos with the busty G-cup girl next door

One day, my busty sister who lives next door came to visit my room. It was crazy! I always watch AV at a loud volume, so I thought she was complaining about the sound leaking out! But she said, "If you like AV so much, do you want to watch it with me?" I was a virgin, so I was excited to watch AV with her! "Hey, show me how you usually masturbate." Hmmmm! What a turn of events! I never dreamed that I would lose my virginity in this way. Please watch the whole story of this lucky boy's first sex.
