Rin Amamiya, 27 years old, 156cm tall, 93H (36.6 inches, H cup), 60cm waist, 88cm hips, works in IT. With short hair and a round face, her standout feature is her large H-cup breasts. Busy with work and without a boyfriend for three years, she occasionally uses dating apps to relieve stress. Serious and cheerful by nature, her recent sexual experiences have been ordinary sex with men she met through apps, but she's particularly intrigued by the electric massager in her room. She uses erotic manga on her phone to masturbate—content filled with women being restrained and forcefully brought to orgasm. Today, driven by desire to fulfill her fantasies, she's seated on a chair and immediately starts moaning when her breasts are lightly groped. She becomes highly aroused when her ass is caressed, and even while shy about wearing underwear, she masturbates with a stick vibrator, moaning loudly as she climaxes. Then switching to a womanizer attachment, she remains continuously aroused, climaxing repeatedly. Her wrists and thighs are taped to the chair, completely immobilized. After intense blowjobs, her panties are pulled aside and penetrated—this out-of-the-ordinary experience excites her, her moans grow louder, and she instantly orgasms. From behind, she exposes her lewd, gasping face to the camera, screaming as she climaxes. While continuing to perform blowjob service, she sucks intensely, swallowing the cock deep into her throat with skilled technique, causing an uncontrollable internal cumshot. Moving to the window area, stripped completely naked, her toned body—evidence of regular gym visits—contrasts erotically with her large breasts. She becomes highly stimulated when her tits are groped, eagerly sucking the cock and transforming into a lustful woman. Forced to continue fellatio, she remains highly sensitive even with vibrator insertion. Moved to the bed and receiving cunnilingus, she emits desperate, orgasmic moans, crying out "I'm cumming, I'm cumming!" as she climaxes. Merely guided into a blowjob, she takes the cock deep into her throat, expertly squeezing with her throat muscles. Skillful at tit-fucking, she transitions from blowjob to cowgirl, sliding cowgirl, thrusting cowgirl, front-to-back grinding cowgirl, and then lowering her body while raising her hips in reverse cowgirl—driven to repeated orgasms in various positions. Even after finishing, she seems unsatisfied, charging into a third round. Finally ending with an internal cumshot, she swallows every drop with a cleanup blowjob. A sexually ripe woman approaching 30, is this her first time or has it just been too long? Overcome by too many orgasms, she experiences genuine, intense pleasure. Special features include self-shot masturbation footage and a "blowjob while being watched" bonus video.
