Yuika Onosaka's line delivery is superb. As an avid fan of Yuika Onosaka, let me talk about her appeal. With her refined facial features, plus her ample bust and outstanding figure, she is an actress who leaves a strong impression.
Through her previous works, I feel her high level of professionalism. You can tell she carefully thinks about how to deliver each line to resonate with the viewer. That is her greatest strength. Since this work is in the "JOI" genre, the actress's skill in line delivery greatly affects the quality of the piece. In that regard, Yuika is perfectly suited for the role. It's wonderful that she doesn't make it feel scripted, but rather speaks naturally as if it were her own words.
The previous "Lewd Language Female Announcer 38: Yuika Onosaka Announcer SP (RCTD-710)" with the anus-showing JOI was also excellent, so I'm delighted to see Yuika's anus-showing JOI again this time. You can fully enjoy her anus twice, around the 39-minute mark and the 1 hour 52-minute mark. Personally, I find the phrase "asshole" more vulgar and exciting than "anus," so hearing Yuika repeatedly say "asshole" is irresistible. The line "Jerking off while looking at my asshole, you're really a pervert, huh" hit a particular sweet spot. Even in scenes where she's wearing panties and the anus isn't visible, the repeated use of "asshole" to make you imagine Yuika's anus is a clever touch.
As a side note, around the 2 hour 8-minute mark, in the scene showing her anus after she cums in reverse cowgirl position, there appears to be a small piece of toilet paper lint or something attached. However, since the focus is mainly on her butt, the anus isn't clearly visible, and in the anus close-up around 1 hour 52 minutes, no such thing is seen, so it might just be a drop of pussy juice glistening. If you're curious, please buy it and check with your own eyes.
