[Reducing Mosaic]MILK-243 "Hey, wanna watch AV together?" While watching AV with the G-cup busty sister who lives next door, I suddenly lost my virginity. Just like in an AV, she made me ejaculate multiple times and took my cherry. Rika Tsubaki.

One day, the big-breasted sister who lives next door came to visit my room. Oh shit! I thought she was going to complain about the sound leaking since I always watch AV in high volume, but no! She actually said, "If you like AV so much, why don't we watch it together?" w My heart was pounding as a virgin, watching AV with her! "Hey, show me how you usually masturbate." Hmmm! What is this development?! I never dreamed that I could lose my virginity in this way. Please enjoy the entire process of this lucky boy's first-time sex.
