21-year-old Rumi has only had two partners, making her an inexperienced girl. During a sensitivity check using a vibrator, her sensitive pussy became increasingly aroused, and even though she cried out "No, no" when stimulated with a vibrator, her body relaxed and she continued to orgasm repeatedly. She experienced handjob with lotion in the bath, as well as periscope blowjob, and on the bed she tried grinding as well. Throughout the day, Rumi accumulates various sexual experiences, clearly showing how deeply impactful her first-time experiences are.
