SONE-634 Highlight: J-Cup Employee Shino Mayu Gets Fucked By Her Hated Boss Until The Morning

Shino Mayu getting a titty fuck cumshot in SONE-634. 篠真有パイズリ挟射.

Shino Mayu is an S1 rookie who debuted in late 2024 with the moniker “The Slimmest J-Cup in History”. Looking at photos of her, it’s really hard to dispute that claim. That plus her slightly longer face definitely helped her stand out from the rest of the S1 roster in my eyes.

In SONE-634, Mayu-chan plays a new office employee who was forced to share a room with her boss on a business trip. A pretty standard JAV trope that eventually sees them having sex and the girl falling for her lecherous superior. Scene 2 is the highlight with a titty fuck that ends in a great titfuck cumshot.

Movie Highlight

Scene 2 – Blowjob + Titty Fuck (1 TF Cum)

This scene that takes place the next morning after Scene 1 where Mayu tried to quietly sneak off but is caught by her boss. He continues to lust after her body by having her suck him off and then titty fucking her to completion.

The camera work was a little too tight in for my tastes. I would liked a wider shot where we can fully see her face and tits as she’s doing the deed. But the nice cumshot saved the scene for me, a true rarity for S1. I would have loved this scene more if not for the rapey vibe of it.

To be honest I wasn’t initially drawn to Mayu-chan due to her more “unconventional” looks. But this scene made me a fan of hers. Those massive funbags have some great potential and I’m now looking forward to seeing more from her.
