Under the guise of a web program interview, we approached a hot spring inn famous for its risqué services and negotiated access. With filming permission granted by the owner, we began investigating the details of their hidden offerings. Though the inn officially provides no full intercourse services, our desire to push things all the way to sex was strong. Among the staff, particular attention was drawn to Fuka, 22 years old. Her D-cup breasts, translucent skin, and beautifully toned waistline amplify her erotic appeal. She takes pride in satisfying guests through her services, and after men with ED told her, "I can get hard with you," she secured a loyal clientele. Just three months after starting as a hot spring companion, she ranked in the top three, with blowjob techniques as her specialty. Starting with a body-washing session in the bath, she quickly brings the penis to full hardness with her renowned fellatio skills. Using her plump breasts for titfucks, she induces ejaculation, finishing with intense cleanup blowjob for a perfect climax. Determined not to let him go until he cums twice, we move into the room. With oil applied, she rides him cowgirl-style while giving handjob, then handjob while he sucks her nipples. Her expert use of tongue during blowjob stands out. Switching roles, she receives fingering leading to squirting. Pretending it's just outercourse, he enters her in missionary position. Though initially flustered by penetration, she can't resist the pleasure and moans loudly. From bent-over position to cowgirl, doggy style with convulsive orgasms, kneeling doggy, standing doggy (with pissing), reverse cowgirl, side-by-side, lying doggy, and finally doggy style again ending with bukkake facial on her pretty face. Even as she protests, "You said it was just outer-thigh contact!", he remains rock-hard and thrusts inside again for round two. The entire seamless progression, climaxing in bringing him to orgasm, is the highlight of this performance.
