Another actress with very large J-cup breasts!
This is the latest new actress from OPPAI, OPPAI is a studio that specializes in actresses with large breasts, her name is Shiratama, the promotion describes her as very cute with perfect J-cup breasts, a bright sunny smile, and lots of charm, she loves having sex very much, her sex drive is very high, she is a perfect match for OPPAI.
The studio made a strong effort to introduce her to intense sex scenes, they covered her with lubricant, brought in a male actor with a large penis, then arranged a threesome with two men, they wanted the new actress to experience how pleasurable adult video sex can be, as her large J-cup breasts bounced, Shiratama quickly became deeply immersed in pleasure, after deep vaginal penetration, she made very erotic breathless moans, her soft heavy breasts swung and jiggled in a captivating way, they looked extremely beautiful and stunning.






















That is why OPPAI declares Shiratama is the incarnation of divine breasts.
Many people feel something is strange, she looks very familiar, the mole on her nose or just above her chest creates strong déjà vu, if you feel the same, you are correct, Shiratama is making a legitimate debut in censored adult videos, but in the uncensored world she is already well-known, she is actually Kamiya Miku from the natural-musume label.
She filmed two titles there, the titles are “051725_01” and “051825_01”, although the uncensored studio promoted her large breasts, they listed her as G-cup, the censored studio listed her as J-cup, this is three cup sizes higher overnight, this could mean her breasts grew quickly or the measurement was more generous.
She also had a major phase selling uncensored videos on FC2, Kamiya Miku has been very valuable to many uncensored creators, under the alias Mayumi alone there are over ten releases, she also used the names Honoka, Rin, Riko, Yuki, Nagisa, Narumi, and Otoha, cup sizes varied from G to H depending on the seller, some sellers emphasized her young-looking face or beautiful buttocks, she has an extremely large amount of work, I will not list everything, but “Henkan-kun” has it all organized if you want to search.
With such high uncensored output, especially during a recent slow period in the uncensored market, it is not surprising that some call her the savior of uncensored adult videos, but how does she perform once she appears in censored videos?
One last question, with such an extensive uncensored history, is an exclusive debut with OPPAI in the censored world undervaluing her?









I see it in two ways, first her agency is Arche, they have a popular senior actress like Mizuto Sakura, but most of their actresses debut with mid-tier studios and rarely get long-term exclusive contracts, second, although she dominated uncensored, entering censored means starting over and following new rules, actresses like Miyashita Rena, Miho Nana, and Shirakami Sakura moved directly to top censored studios after uncensored work because their appearance suggested future idol status, for Shiratama her uncensored history did not harm her, her breasts are truly outstanding and perfectly suit OPPAI’s brand.
If you think OPPAI is insulting her by debuting her there, it probably means her face, breasts, and performance are exactly your preferred type, based on the examples of Miyashita, Miho, and Shirakami, censored studios do not discriminate against actresses with uncensored pasts, being chosen by OPPAI simply means the executives saw her as an ideal fit for their roster.
Now that she has officially entered censored adult videos, we can watch her develop further, there will be the usual annoying mosaic covering the genital area, but her makeup and styling should improve, right?
