SONE-678 Review: Shino Mayu Seduces with Her Clothed Big Tits

SONE-678 stars Shino Mayu in a CFNM-themed movie with a focus on clothed titty fucking. I’ve rather liked her since watching her in SONE-634, so it’s nice to see her finally get a full paizuri movie. There are 5 scenes all ending with a titfuck cumshot.

Movie Review
Scene 1 – Office Sex (1 TF Cum)

The first scene takes place in the office where Mayu’s colleague gets tempted by her huge tits and starts groping them. He fucks her cleavage for abit through an opening in her shirt and later through her bra. After some intercourse, he ends the scene by titty fucking her to completion.

This scene had the shortest titty fucking out of them, which is a shame because the technique was pretty good. It was mostly hands-free and his cock was wedged firmly between her tits. And the money shot was decent too.

Scene 2 – No Bra Titty Fuck (1 TF Cum)

In Scene 2 Mayu has a guy repairing the air-conditioning at her home while she’s wearing a skimpy camisole with no bra underneath. The guy gets tempted by her sweaty cleavage and starts groping her tits and then asks her for a titty fuck, which she obliges until he cums between them.

I liked everything about this except the fact that the penis literally disappeared between her big tits. Credit to Mayu-chan, she actually tried to make it work at the start by trying to shift her clothing and moving into awkward positions. But poor guy stood no chance against those weapons of mass destruction so I’ll still call it a win. I’m becoming more of a fan of hers with just how soft her tits looked during the paizuri.

Scene 3 – Yoga Sex (1 TF Cum)

Mayu plays a yoga instructor in Scene 3, again tempting her student with her sweaty cleavage. She gets some oil to shine up those beautiful mammaries as he fucks her and finally straddles her for a titfuck cumshot.

Definitely the weakest one of the bunch, and through no fault of Mayu-chan’s. The paizuri in the first half looked great, but the ending was ruined with that pathetic excuse of a cumshot.

Scene 4 – Schoolgirl Bloomer Titty Fuck (1 TF Cum)

In Scene 4 Mayu plays a schoolgirl in a sports bloomer that got wet from the rain. She meets the school principal who confesses his obsession for her tits, which he then gets to caress and fuck to completion.

This one is my favourite finish. For me, the less clothes the better, and for this one we got the full unobstructed view of her big tits at the end. It’s also helped by the decent cumshot with a healthy spurt at the start. The clothed paizuri before that is still plenty erotic though, and at about 8 minutes total, this is some good fap content.

Scene 5 – SNS No Bra Sex (1 TF Cum)

For the final scene, Mayu is shooting a social media clip advertising her new bra. After that her co-star goes horny mode and removes her bra underneath her vest. They fuck around for awhile before he straddles her covered-up tits and fucks them to completion.

It’s not my preferred cup of tea as mentioned above, but I can definitely see the appeal as it is objectively some decent titty fucking, with a passable cumshot too. It also helped a ton that Mayu-chan for once looked like she was a willing participant and enjoying herself here.

Summary
Overall while I would have preferred this movie without the clothed theme, this still gets a hearty recommendation from me for being Shino Mayu’s first titty fuck movie. And 3 out of 5 passable titfuck cumshots is honestly pretty darn good for S1 standards, with Scene 4 being the standout for my fellow maniacs to jerkoff to.
I’m becoming a bigger fan of Mayu-chan with each new release. Acting-wise this wasn’t too great as she’s mostly playing the submissive party. In fact that applies for most of her movies so far, so hopefully she gets a chance to show off a different side soon.
