Hina-chan, my childhood Hina, always hangs out in my room with her panties exposed. She's a tomboyish delinquent girl who is foul-mouthed and sometimes violent towards me, but deep down she's a very innocent and kind girl. One day, I got a girlfriend and Hina-chan, who was worried about me because I was still a virgin, decided to watch some adult videos with me to study... But somehow we both started to get horny... I couldn't hold it in any longer... and finally I attacked Hina-chan...
