My new stepdaughter Koharu has a strange habit of walking around the house in nothing but a thong. I try to keep my cool, but her bouncy peach butt is always right in front of me, keeping me fully erect! One incident pushes us over the edge into a forbidden relationship. The thrill of sneaking around my wife for some illicit, high-stakes sex is absolutely intoxicating.










A middle-aged man who is a newlywed. Koharu-san from the J-category arrives as his stepdaughter, appearing in a super cute sailor uniform. The awkwardness between them was charming, and I thought, 'How will they bridge the gap and get into an erotic relationship?' But in the very next cut, she appears naked in just a thong, and without any shyness, she just starts eating dinner. The first sexual contact isn't a kiss or touching her breasts or butt, but immediate penetration. In terms of eroticism, it doesn't build up gradually; it feels like it's taken straight to the peak. The story is a bit wild, but it's enough to enjoy Koharu-san's erotic body and dialogue. I liked that they stuck to just the thong instead of going fully nude; it provided a nice sense of consistency.
Just as the title suggests, this work only works because it's Koharu Suzuki. That said, her beautiful butt was truly magnificent.
Koharu has such a perfect figure, and she's a nudistโthere's no way anyone could hold back! It's great that she's in just a thong for almost the entire video, and all the action involves just sliding the panties aside. The ending twist actually made me laugh.
The scene where they do it is erotic. Aside from her butt, her body is so great that I never get tired of watching her, though I feel like she lacks motivation sometimes. Haha.
*Personally, I'd like to see a setting in which a character is forced to wear only a thong and reluctantly obeys.
