23-year-old new office worker Ruka applied for a handsome male actor's overnight trip to Mount Takao after breaking up with her boyfriend. Her big breasts are noticeable even through clothes, and she's full of anticipation for the date. During the hike, while being careful about forbidden words, she gets scared riding the lift and ends up pressing close, blurting out too many forbidden words, leading to sex. Initially shy, Ruka starts getting turned on when her big breasts are groped, even sticking her tongue out from pleasure. She takes deep, intense penetration beautifully. After sex, while sitting around a bonfire, the male actor secretly invites her again and she easily agrees. She wraps both legs around him, holding him tightly as he cums inside her.
