Chihi was the most beautiful girl among all the students I've ever taught. She was often said to resemble a young actress from an idol group, and I had long been captivated by her innocent appearance. I was aware that she had feelings for me even during her time as my student, but I always maintained my role as a teacher and never crossed that line. Once, she confessed to me, and I told her, "If you pass and graduate, then maybe." I admit I'm a pervert, but I've always kept my work and personal life strictly separate. I never touched a student. Yet Chihi deeply admired me and sincerely desired to be trained by me. I understand that a student in love with her teacher holds onto those honest feelings with all her heart. I couldn't resist the urge to cover that pure affection with shame and humiliation. Chihi successfully passed the entrance exam for her desired school, and the day after graduation, she came to my apartment. I had no reason to refuse her. True to her innocent looks, she was a virgin. Full of curiosity, she gradually became more and more enthusiastic about sex. This video documents the first time Chihi participated in a gangbang. I'm submitting it as a keepsake. Since it's a special occasion, please use light mosaics only on the masked areas. I'll submit more if the opportunity arises.
