Rio Hamasaki, the industry's top-tier beauty, takes on a role as a serious mother teaching her son about sex. The contrast between her stoic teaching and her inability to resist pleasure once she starts is the highlight.




















Rio-chan's breasts are magnificent, massive beauties that I could watch ten thousand times and never get tired of. Being with breasts like these makes me feel like I could climax over and over again. The foreplay is generally on the softer side, but it has a nostalgic, old-school vibe that I actually quite liked. The highlight is the missionary position with her arms pressed together; Rio-chan's massive, beautiful breasts are emphasized even more, swaying in such an erotic and stunning way that it was incredibly arousing! However, the other positions felt a bit lackluster, so I wish she had put more effort into the cowgirl and doggy styles. The final act was a bit too dark and the piston rhythm was a bit short and choppy, which was a shame. With breasts this incredible, they’re bound to sway erotically in any position, so if you focus on that, this is definitely a winning title. I don't think there are many people out there with breasts this amazing.
With a body like that, you can't help but want to creampie her raw. The scene where she jerks him off in the infirmary was great too.
The way she explains her nipples, clit, and pussy to her son so thoroughly and tenderly was incredibly erotic. Rio Hamasaki's perfectly shaped, soft-looking massive breasts are legendary in AV history.
From the costume and makeup to the acting and calm tone of voice, she perfectly pulled off the 'middle-aged woman' vibe. She was a bit heavier during this period, and she used that to her advantage for the character setting. She’s a beautiful woman, but I’m not into the 'mature lady' genre at all—I prefer the young and bubbly Rio Hamasaki... However, the breast-fondling lecture at the beginning was a total hit. I kind of wish they had done more, like having the boy beg to 'touch more' or including more rear-groping and paizuri. Overall, the breast-fetish factor is high. It’s refreshing to see Hamasaki in a calm, 'big sister' style role, which is rare for her. Her gentle voice is just irresistible. <I’ve rated this lower because Rio Hamasaki’s works are generally top-tier. In reality, it’s a 6-star performance or higher.>
*I think the age setting is a bit unreasonable, but since it's AV and Rio-chan, I guess it's fine. (lol) At the most sensitive time in his life, even though he's a mother, if Rio-chan's breasts and body were shown to him, his son would get excited. (lol) In the second half, when the son comes in while the mother is sleeping and they end up having sex, I see the scene where the son is sucking her breasts, and I think that sometimes female parents feel a little bit when they are breastfeeding their children. The only thing I was disappointed with was that the last scene of him having sex with his son was shot in a dark room, so you couldn't see Rio's facial expressions or body clearly, and it felt like it took a little longer. In terms of the structure of the work, I think it would have been better if this part had been made a little shorter, and before that there was a scene where, for example, the son comes in while the mother is taking a bath and washes herself. Therefore, the rating will be 4 stars, minus 1 point.
