A playful tease turns into a nightmare for the sister. Her virgin brother takes her seriously and pounces the moment their parents leave. He's so clueless and inexperienced that he doesn't even notice she's already cumming, just keeps pounding away until she's forced to climax over and over again before their parents get back.










Her 'reluctant' acting feels a bit awkward, but you stop noticing once the erotic scenes get going. She cums a lot, so it's definitely a solid fap-material video. However, every time the actress cums, the actor slows down his thrusting, so you don't really get to see that 'non-stop pounding regardless of her climax' action. This work should be all about relentless, high-speed thrusting no matter how many times she cums, but it fails to deliver on what the title promises. I've listed a lot of negatives, but even so, it's highly practical.
The brother goes into full-blown lust mode after being teased by his slightly sassy, schoolgirl-uniform-clad sister. From the sudden standing back-entry in the entryway to the way she slowly 'succumbs' to her brother's beast-like, erotic rampage, her performance was incredibly seductive. Despite her initial resistance, the kissing, fellatio, clothed play, facials, and 'cleanup' oral were all just too much. Seeing Kanon Kanon clearly enjoying it while playing the tsundere was super erotic and cute.
This series is as good as ever. I can't get enough of the actress's reluctant reactions to that relentless thrusting.
I think the premise of 'taking' the 'runaway piston' from the title suited this actress perfectly. She has a cute face but is surprisingly tall with a healthy physique... they hammered away at her so hard it felt like they were breaking her, and combined with her signature intense moaning, it built the world of the film perfectly without breaking immersion. Personally, though, I think this specific moaning only works for this film; it would feel out of place if she did the same thing in other works.
I think it's a good video. The scene where she's being taken from behind and enjoying it was great. I also liked that it's a clothed play. However, I wanted it to be a bit more intense and rough, so I'm giving it 4 stars. I'd recommend this one.
