Midorikawa-sensei, my boyfriend and personal tutor, is an exceptional medical school student. After he confessed his feelings and we began dating, I unintentionally lost my virginity. I believed it was too late for me since everyone else around me had already experienced their first time. Meanwhile, my sister, who lived separately from me, returned and expressed interest in engaging in sexual activity with me after spending several days together.
