SONE-798 Highlights: Embarassing Nip-Slips of Kohinata Miyu’s Big Tits

SONE-798 features Kohinata Miyu in various situations where her big tits would “slip out” or get seen through her clothes, which of course causes the nearby guy to jump on them. Very similar theme to Tano Yu’s movie last month. The movie has 5 scenes with 3 of them ending in a titfuck cumshot.

Movie Highlights
Scene 1 – Blowjob + Titty Fuck (1 TF Cum)

The first scene has her welcoming back her drunk boyfriend wearing a bath towel. Which naturally came off as she’s trying to get him situated with the help of his colleague who brought him home. After some breast fondling, she gives him a quick blowjob and titty fuck to completion while the boyfriend is sleeping behind them. Miyu-chan looked great naked as always, but the guy barely lasted 30 seconds into the titty fuck before he came. Not that I blame him as anyone would be one-pump chump between those “marshmellow boobs”. What I do blame him is that poor excuse of a cumshot where you could only barely see some white semen in the opening of her cleavage.

Scene 4 – Massage + HJ + Titty Fuck (1 TF Cum)

Scene 4 has Miyu playing a “dispatch masseuse” where she gets hired for a massage for a client at a hotel room. During the session one of her breasts slipped out of her braless low-cut shirt which the guy quickly jumped on. This one had a longer foreplay with some breastfeeding handjob, but the paizuri was almost as disappointing, lasting about 90 seconds with another weak cumshot mostly obscured between her tits.

Scene 5 – Sex Scene (1 TF Cum)

The final scene has Miyu doing a photoshoot wearing a skimpy bikini outfit that you just know is going to come off as she’s jumping about. This was mostly an intercourse scene with about 3-4 minutes of paizuri, and ends with the guy cumming while straddling her tits. The cumshot again wasn’t the strongest, but at least it had a little volume to form a nice-looking pearl necklace for Miyu-chan. This scene was again heavily reminiscent of Tano Yu’s scene, right down to the theme, the male actor and the way which he came.

Summary
Overall a rather disappointing movie for Kohinata Miyu who I have come to like since I started watching her works for this site. The weak cumshots I have sadly come to accept and expect from S1, but even all the paizuri segments were too short to be satisfying. The theme was also not to my tastes with how she was resistant in all of the scenes and didn’t loo like she’s enjoying it. All in all, a “highlights only” movie for me and hopefully her next one will be better.
