After her husband left 15 years ago, Rikako raised her son alone. Now a grown man, he treats her to a hot spring getaway. But he has a hidden agenda: fulfilling the childhood vow he made to 'marry his mom' once he grew up.




















Aoki-san is a beautiful woman with a great body, but this lacks the 'eroticism' required for this series. There's hardly any tongue action, the mosaic is huge, and I can't really see the technique. It's not satisfying enough to get off to.
*Rikako Aoki wore plain clothes and had the face of a common aunt, and the age difference between mother and son was good, and she completely resisted her son's requests, so it was quite erotic, like a real mother and son having sex. I felt violated and excited. This time, the setting of the indoor bath was even more erotic, and the camera angles for the scene where Kako shamefully exposes herself naked as she changes from a mother to a woman, and the whole body shot when her son licks her whole body, were also good. I felt the agony of cunnilingus in the cowgirl position, and when she transitioned to sixty-nine, her words, ``My legs hurt,'' were very real. The sticky and dirty sex in the second half made me feel like an adult woman, and it was also exciting to see her licking the soles of her feet and writhing in agony, saying, ``It feels good.'' Her moaning voice is erotic, and the way she uses her hips is exquisite. Pretty erotic. There is a story, and the roles of the mother and the woman are excellent. Personally, I think this is a masterpiece in the series, along with the works of Ayako Inoue and Maki Tomoda. This was the first time I've watched this series three times in a row, probably because Rikako Aoki's female body was so naughty.
*I have watched all of this series up to the latest work, Shinzatoji (as of December 27, 2014), and I can confidently say that Nasu Shiobaraji is the best work. I'm not particularly a fan of Rikako Aoki, but I was drawn in by her charm, acting, and story. It is one of the highest level in all respects.
It's rare for this series to cast actors with a realistic age gap suitable for a mother-son dynamic. Rikako Aoki gives a great performance. I've seen good works like the Shibukawaji in Takasaka and the Atamiji in Tomoda; while this one is slightly less skilled in terms of technique, it features a mature, intimate chemistry that feels like a real mother and son. The highlight is the 34-minute sequence starting at 67 minutes: she strips naked on the bedding, exposes herself to her son, and they begin mutual masturbation. From the cunnilingus at 77 minutes to the 80-minute face-sitting where he obsessively licks her, leading to her climax, followed by a 69 position with affectionate oral, and finally allowing him to ejaculate inside at 101 minutes—it's excellent. A common issue with this series is that the lighting is too dark; I wish they would put more effort into the camera work for the cunnilingus and sex scenes to make them more erotic. It really felt like watching a real mother and son having sex.
I get so excited watching her shy away from the forbidden act, only to eventually give in and fall into pleasure. The direction, the acting, and the quality of the actress—everything is top-notch.
