Kusunoki-san, who has big natural breasts, and a male junior to her, go on a business trip together. That night, only one room was booked at the hotel...so we had no choice but to stay together in one room. Kusunoki asks a junior boy who is too upset about spending the night in a shared room, ``Are you a virgin...?'' From there, he succumbs to the heat of being a virgin and starts having sex... Even after the night ends, his sexual desire does not run out. It's hard to believe that she just graduated from virginity...A big-breasted senior who kept being made to cum by a former virgin until she was about to check out.
