Kurumi, the sauna's star attraction, has regulars lining up just to catch a glimpse of her massive I-cup breasts. She treats sore customers with intense, bone-melting massages, and in the bath, she doesn't hesitate to give hand jobs to those who get excited by her touch. Even when her clothes turn sheer from sweat and reveal her nipples, she stays committed to her service, taking every customer all the way to the bedroom.




















This is one of the few works by Kurumi Koi. The sauna setting is a bit random, but the actress's body is simply top-tier. If you're a fan of big breasts and don't know Yui Serizawa, you absolutely have to buy this. She's still in her prime.
She has a stunning face and massive I-cup breasts. That alone is erotic, but with her facial expressions during oral sex, the way her face contorts during intercourse, and her slim, toned waist contrasting with those huge breasts, she’s packed with erotic elements—everything she does just oozes sex appeal. She doesn't rely on special gimmicks, and she doesn't seem to be trying too hard to look sexy, but her earnestness in every scene is strangely arousing. With specs like hers, any kind of play is enough to make you finish. From the deep kissing with her mouth wide open and tongue out, to the pained expressions during oral, and the way her breasts squish against the actor's stomach during 69, combined with her otherwise slim, sexy physique—it’s just addictive. It’s not like I watch her all the time, but she’s the type of actress who suddenly pops into your head and makes you want to watch her again.
I've liked her since she was with Alice. She has a truly magnificent bust. I hope she keeps releasing more works.
A film where I-cup bombshell 'Kurumi Koi' plays a cheerful, sexy sauna poster girl. Taking over for her sick father, Kurumi-jo manages a struggling sauna. To boost business, she starts a 'cock-washing' service while wearing a tank top that shows off her cleavage. She also induces more sweating by having nude sex with customers in the sauna. After massage and handjob services, she eventually lays out a mat in the public bath to open a 'pop-up soapland.' Armed with her 'bouncy 98cm breasts' gifted by the gods, she captures the hearts (and crotches) of her customers with a blatantly erotic approach. It's truly a textbook big-tits AV—a film all about breasts, from start to finish.
*She originally debuted at Company A and was active as Yui Serizawa. Company A was a treasure trove, but Boin. Big breasts on BB label I feel like I specialized and blossomed. This work depicts places that people come into contact with on a daily basis, such as saunas and bathhouses. Because it is mainly used, some parts feel more realistic and real. Personally, I like everything about short height, baby face, big breasts, sweet voice... It is an ideal system, especially when being pushed up from the back. Or the two big breasts from the bottom sway up and down and left and right. I'm so excited. If you want to take advantage of her, take a route that specializes in big breasts like now. Probably. Because it also has a pure image, I think it's OK even if it's a sex type where you get your big breasts fucked. I think we can look forward to the future as long as we don't make a mistake in choosing the works.
