Women in their 30s stumble into men, each carrying their own personal circumstances, ultimately being brought to climax. [Part One] Reiko is 32 years old, 162cm tall, weighing 53kg, with measurements B90 (D)·W63·H90. She married at 28, but due to work-related conflicts, they drifted apart and divorced—now a divorcee, she has dated 11 men, mostly coworkers, and has a weak resistance to persistence, unable to say no. Recently, she meets her 7-years-younger boyfriend 12 times a week, enjoying sex. Relying on youth, they've had intense sex three or five times, even twice in a private open-air bath. She's known to "orgasm easily," and during a sensitivity check on the sofa, blindfolded, her sense of shame fades—she spreads her legs wide, allowing her entire body to be touched. Though she tries to suppress her voice, she's highly sensitive, loudly crying out "I'm cumming, no—!" before collapsing limply after climaxing from vibrator stimulation. [Part Two] Shiori is 32, 152cm tall, 46kg, with measurements B83 (B)·W58·H85. Petite with a Lolita-style face. Divorced twice, her most recent divorce was three months ago. Her first experience was with a 17-year-old boyfriend; she married her first husband at 21, remarried, and divorced again. She claims to be thoroughly disillusioned with men, yet when aroused, she wets her panties, moaning while indulging in pleasure. [Part Three] Kiyomi is 38, 170cm tall, 49kg, blood type AB, with measurements B83 (B)·W60·H88. She practiced classical ballet but struggles with conversation, becoming irritable when asked about sex. Her first experience was at 13 with an upperclassman four years older—she wasn't interested herself, but complied due to his insistence. When restrained, she feels irritated, yet a tissue is carefully inserted as a blindfold. Tied to a punishment chair, she's stimulated with a brush and hands. She admits "It feels good" when her nipples are caressed. Her body arches from rotor stimulation, her upper body turns bright red, writhing in pleasure before suddenly and intensely climaxing. She also has experience in the sex industry.
