Movie Highlights
Scene 2 – Bathroom Oiled Swimsuit Intercrural + Blowjob

This scene was very reminiscent of some of my favourites like MIDA-037 and MIDA-154. Bathroom oiled swimsuit into assjob into thighjob. A real shame It did not finish as the length was perfect and even the guy was close to the edge. Instead we get a blowjob that didn’t even end with him cumming inside her mouth.

Scene 4 – POV Pantyhose Blowjob + Oiled Assjob (2 AJ Cum)

Scene 4 is another outercourse scene with Rio wearing a pantyhose over her school uniform. There’s some lengthy face-sitting and 69 before the camera changes to a POV perspective. She gives her stepdad a blowjob and then oils up her ass and grinds him to completion twice.

The last scene may have been a tad disappointing, but this one certainly made up for it. POV + oiled + actress being naked pretty much checks most of my boxes. The assjob was super erotic with over 6 minutes of totally hands-free grinding. My only small gripe was the cumshots which were both off to the side due to them using a prop dick for that. Still the volume of both shots made them look very good and being done consecutively makes it a pretty jerkable scene for ass maniacs.

Summary
Overall 2 very solid scenes from Rukawa Rio who I didn’t realize I had missed. She was quite high on my watchlist in 2024 due to her frequent pairings with some of my favourites like Yayoi Mizuki, Misono Waka and Suehiro Jun. All boasting big asses and having done a lot of ass/thigh pinching. And for me this was Rio-chan’s breakout solo movie as she gets to show off her own figure with some fapworthy ass / thighjobs.
Sadly this year she was mostly stuck with VR or B-movies, but seems like she’s starting to get more opportunities again so good for her. Hopefully we get more of what we got today, and perhaps even a few more collabs with the ones I mentioned above.
