Movie Review

Scene 1 – Sex Scene

The movie starts off with Sunao working overtime in the office with just her subordinate before she gradually seduces him using her big tits and plump ass, eventually leading to creampie sex. Some pretty erotic foreplay and lots of nice camera shots with close-ups to Sunao-san’s tits and ass. Sadly no “pinching” here at all.

Scene 2 – Thighjob Scene (1 TJ Cum)

Scene 2 sees the pair in the document room, with Sunao wearing a short skirt and T-back panties that completely exposes her asscheeks. Which the guy naturally couldn’t hold back as he starts groping her ass and stuffing his face in it. After some lengthy facesitting, she strokes his dick with her legs and gives him a quick blowjob before clamping it between her legs and thigh fucking him to completion.

Much better visuals here compared to the last scene without the pantyhose and the choice of outfits. The thighjob position was an exceedingly rare one where she is laying down and perpendicular to the guy, which I’ve only seen one other time. The “radish-like legs” mentioned in the movie title was also spot-on, as Sunao’s legs were so thicc that you couldn’t see the penis between them at all.

And yet despite that almost airtight seal, we still got a nice little puddle of semen visibly forming between her legs after the finish, giving us the best of both worlds. The only thing I wished for was a little more force behind the cumshot, but this was still an incredibly jerkable scene.

Scene 3 – Thighjob Scene (1 TJ Cum)

Scene 3 sees Sunao dragging the guy into the office toilet under the excuse that she’s too scared to go alone. She immediately drops the act by making him watch her, before even having him clean her up afterwards. As a reward she lets him play with her boobs before giving him a blowjob and thighjob to completion.

Normally a toilet scene would have docked a few points from me, but my god, what a sight. This full-body rear angle is practically the hallmark of studio Lunatics and by extension SmokeCity, and being a thigh maniac whose fetish was practically cultivated by them, I absolutely love this framing. It lets us enjoy both the thighjob itself and flashes of Sunao-san’s facial expressions at the same time.

I also loved that she was the one doing all the stroking during the finish. As she repeatedly squeezed and relaxed those massive glutes, you could actually see dents and waves forming across that absolute dumptruck of an ass. Imagine the pressure that must be exerting on that lucky little dick, and rightfully it shot out a couple decent ropes to pay off the action.

Scene 4 – Thighjob Scene (1 TJ Cum)

Scene 4 takes place on the office staircase where Sunao playfully quizzes the guy about whether he likes older women while constantly flashing her panties. He eventually gives in and dives face-first between her legs. After some breast fondling and sucking, she gives him a blowjob and thighjob for another cumshot between her legs.

Yet another very unique thighjob position, this time with Sunao-san facing upwards and scissoring her legs and bending in an L-shape, almost like a crab. She didn’t quite have the same flexibility as that other movie, but nevertheless it’s a great change-up as we get to see both her full face and her tits bouncing around in this position. The money shot used a fake dick for it, but it did resulted in a couple nice spurts of “cum” jumping out, and that’s a trade that I’ll happily take any day of the week.

Scene 5 – Sex Scene

The last scene has Sunao dragging the guy into the empty CEO’s office for some mischief. While she’s having a good time fooling around in the chair and couch, so is he as he’s oogling at her garterbelt + T-back outfit, until he pulls his dick out and starts stroking it on her ass. And they fucked all over the office until she gets creampied.

Nice action overall and we even get more of that sideways thighjob here where the penis was actually visible, but sadly this one did not lead to a proper finish.

Summary

After giving us a little taste of Sunao-san’s first thighjob finish back in SMOK-036, I’m so glad they fully committed and gave her an entire thigh-focused feature. While her phat ass has definitely been highlighted in the past, it’s leagues different when done by a studio that has been putting out great thighjob scenes and packaged together with her slutty mature female boss aura. And it’s nice to see them still reliably feeding us maniacs when MOODYZ has visibly been slacking in that department so far this year.

The opening and closing sex scenes are noticeably weaker because both rely on creampies, but the middle 3 outercourse scenes are all highly jerkable, and judging by how many liked her previous work, this one is definitely a must-watch for thigh maniacs.

If you enjoyed this movie, Yayoi Mizuki’s SMOK-016 is a no-brainer to check out as that is the “other work” that I’ve been referencing throughout this review, feturing the exact same structure and arguably even better cumshots. That one came out literally a year ago on the first week of July as well, but I sure hope they won’t make us wait another year before the next entry, as there are so many freelancers that I would love to see in this like Onosaka Yuika, Hatano Yui, Onami Aya and of course Aizawa Miyu.
