Yuki, 45 years old. Height 153cm, weight 46kg, blood type A. Bust 80 (C), waist 60, hips 83. At 18, she lost her virginity to a 21-year-old man—who later became her husband. She lived an ordinary life as a working wife and mother of three. Her husband started a business, failed, accumulated massive debt, and filed for bankruptcy. She considered divorce, but ended up dragged into his financial collapse, ultimately declaring bankruptcy herself. Their marriage became irreparable. Alone and craving dependence, she began having affairs, but partners her age were older, emotionally distant, and sexually dull—she never experienced orgasm. To her, sex simply ended when the man came, and that was normal. On the shoot day, she was nervous, lacking confidence, filled with anxiety. Today’s partner was nearly an amateur, overly talkative, so they decided to skip requests and go for raw, intense sex. It started with a boyfriend-like atmosphere, but this amateur man was premature—his penetration time extremely short. After pulling out once and receiving a blowjob, he climaxed instantly during second penetration. She gasped, “Huh? Huh?” then asked, “Was it fast?” Since he didn’t touch her clit or breasts, she wasn’t sure what to expect. But then, turning onto her stomach, grabbing her panties, exposing her ass—that’s when the real action began. She moaned continuously, “Haa, haa, ahh,” without pause. Her left hand gripped the carpet tightly, as if holding onto pleasure itself. Her hips moved rhythmically, mimicking the man’s thrusting. Her voice grew louder, and as he approached his final climax, she violently rocked her hips up and down, as if driving his cock deep into a hole in the floor. She reached orgasm, then, even in the afterglow, lasciviously grinded her hips. The sight of her jiggling ass flesh was intensely filthy. Though she claimed she “didn’t understand what orgasm felt like,” once blindfolded, restrained, and teased with feather touches and a vibrator, she began moaning and thrusting her hips. Her nipples stood erect, highly sensitive. Even if she didn’t realize it, her body reached climax repeatedly. When fingers entered her pussy, she trembled her hips and begged, “More~!” Then suddenly—spurt, spurt—she squirted. Unaware herself, she discovered her body was highly sensitive, easily wet, easily orgasmic, easily squirting. After showering and changing into underwear, we see the raw, mature woman’s back view—her slightly sagging ass, the soft flesh resting over her panties, the act of putting on her bra, the sight of her pulling up pantyhose.
