Nagisa Koisei finally allows unprotected sex to celebrate her 2nd anniversary since her debut! Filled with anxiety and confusion about her first ever unprotected sex, she experiences her first raw cock insertion! Thanks to abstaining for about a month for this project, she immediately reaches orgasm from the raw pleasure she has never experienced before! Gradually becoming addicted to the raw experience, she loses herself as thick semen is poured deep into her vagina, and she climaxes so intensely that she squirts.
