Movie Review

Scene 1 – Handjob + Sex

Scene 1 starts with Momona roleplaying as a nurse “taking care” of a sick patient. She teases him with some French kissing and nipple teasing, followed by blowjob, titty fucking and handjob until she jerks him off onto her tits. She lets him suck on her breasts and eat her pussy until he’s hard again, which she then fucks for a creampie ending.

Multi-cumshots have always been my thing as regular readers would know, and I also quite liked the teasing at the start where she kept baiting him in with her lips, getting him ready and puckered only to draw back with more dirty talking.

The biggest issue was probably the nurse uniform staying on the whole time, which hurt the eroticism for me quite a bit. There also no paizuri finish which was especially disappointing since this male actor Nanao-kun can usually shoot some good loads. Even the nipple fondling handjob finish looked strangely weak here which really limited the payoff.

Scene 2 – POV Oiled Titty Fuck + Sex (1 TF Cum)

POV handjob with Koibuchi Momona

Scene 2 switches things up to a POV perspective with Momona sitting inside an inflatable pool wearing a skimpy bikini. We get a nice view of her getting oiled up and playing with her breasts and pussy, before she turns her attention to our erect dick. She services us with some kissing, nipple teasing, blowjob and finally titty fucking to completion. After that she removes her swimsuit and lets us fuck her for a second creampie finish.

The POV immersion was great especially with Momona-chan being fully naked for the second half. The paizuri itself lasted a little over 2 minutes which was decent enough, and the cumshot was quite good had a huge amount of semen flying out, albeit fake. My only real complaint was the bikini still being on during the paizuri, which lowered the visual impact for me. At least she still made use of it with some clothed paizuri technique instead of wasting the outfit completely.

Scene 3 – Titty Fuck + Sex (1 TF Cum)

Scene 3 gives us another multi-cumshot focused sequence with Momona-chan starting things off with some kissing and nipple teasing, before transitioning into a handjob and oiled titty fuck to completion. She follows it up with a kneeling reacharound blowjob and handjob for another finish, before ending with some breastfeeding and 69 handjob for a third cumshot.

Very good outercourse scene with a nice variety of positions throughout. Personally I tend to enjoy these repeated handjob finishes when they are towards the end, as something about it just reinforces the fantasy for me about getting milked dry. The paizuri itself lasted over 6 minutes which was pretty lengthy, although sadly the money shot was quite weak despite them once again relying on a fake dick.

Scene 4 – MMF Sex Scene (1 TF Cum)

For the last scene Momona gets fully oiled up before being tag teamed by two guys. Things start with a blowjob and titty fuck combo where one guy finishes between her tits while the other ejaculates into her mouth. Afterwards she kneels down and sticks out her ass while both guys rub their dicks over her asscheeks until they jerk off on them, before the scene ends with intercourse sex where she gets creampied by both of them.

Not really a fan of MMF content personally, so this one lowered the overall enjoyment for me quite a lot. Momona-chan did at least get fully naked towards the end which helped the visuals somewhat. The paizuri finish was also somewhat disappointing, as there was some visible semen during the climax, but the camera angle was awkward and the other guy in the frame basically cock-blocked the entire money shot which made it hard to properly enjoy.

Summary

Overall this was decent enough overall thanks to the multi-cumshot theme and Momona-chan’s seductive energy. Sadly not as paizuri focused as I would have liked, and the last gangbang scene ended it on a somewhat sour note. Scene 2 was definitely the standout for me with the POV immersion, and very worth adding to the jerk folder. Scene 3 was also quite enjoyable for fans of Momona-chan who likes longer edging sequences.

SOD is a studio as a whole whose output can vary wildly depending on what kind of material they give their actresses to work with. And Momona-chan has been a victim of that with some pretty underwhelming works so far. Hopefully things will pick up for the second half of 2026 with a couple more works like this.
