A brother and sister with a secret: they can't stop having sex whenever they are alone.










*Renasa Fukiishi, the older sister who secretly interferes with her younger brother without paying attention to her parents. No matter how you look at it, it looks like the older sister is in heat. Since she's a mature woman, I thought it would be better if she was my stepmother, but when I actually saw her, I thought it wouldn't be strange if she was my sister. Even if her big boobs sag, her beautiful face is still youthful. It's been a while since I saw Renasama Fukiishi's work, and I feel like I'm going to be hooked on it now.
She's appeared in many works, but I think this one is the best. It fits the drama well, and her chemistry with her co-star is perfect.
The 'Rena Fukiishi' edition of Premium's incest drama series, 'Just the Two of Us → Instant Sex!' It starts at a family breakfast, where the younger brother 'Taichi,' a student preparing for exams, is being scolded by his strict father. Right next to him, his lewd older sister 'Rena' is busy groping his crotch. As soon as their father leaves, she starts jerking him off under the table. They 'pause' when their mother returns, but immediately resume sex in the entryway. They strip off their clothes and go at it completely naked. The way they insert without a moment's hesitation makes it clear they have sex all the time. No condoms, no problem; creampies are the norm. She injects her brother's sperm into her pussy every single day. A truly dangerous family. 'Mixed bathing' is also part of their daily routine—and when they're alone in a confined space, you know they aren't just washing each other's backs. In the second half, with both parents out, they dive into a 24-hour endurance sex session. It's a dream-like scenario: spending every waking moment having sex with the 'sexiest sister in the AV industry,' Rena Fukiishi.
This is a stretch~ they definitely don't look like siblings lol. If you turn a blind eye to that and just focus on the sex scenes, the content is pure domestic debauchery. Rena Fukiishi, shaking her mature, sagging breasts while reaching climax, was very erotic. However, the fact that they are constantly naked and having sex in a house where other family members are present is just too unnatural, don't you think? lol. There are many sloppy points that make you want to nitpick, but since Rena Fukiishi was still sexy, I'll forgive it lol. It made me want to be a younger brother falling for his sexy older sister lol.
If I had a sister like this, I'd definitely pin her down. But this time, she's the one taking the lead. She kisses so aggressively, and her tongue work is just too erotic. I want to grab those sagging breasts with both hands.
