I'm a virgin and it was my daily routine to exchange morning greetings with the super cute girl who lives next door to me. One day, I was hoping to become closer to her, when I heard what sounded like her scream coming from the next room... "What?! Sister, are you being attacked?!" I rushed out of my room and knocked on her door -- and who appeared before me?! Clack... "...Haa...Haa...///" A hot, filthy girl came out of the next room, out of breath and with a flushed face --!? Graduation from virginity in the best way! Neighbor Gacha SSR! She's so innocent but has such a crazy sex drive! I'm so lucky to have such a girl living next door!
