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

The first scene has Yu teasing us while her sister (our girlfriend) is working in the background. She sucks our dick and titty fucks it for a bit before getting on top for intercourse. She ends with a titty fuck cum countdown but naughtily holds the count at 2 as we fail miserably and cums between her tits.

A fun opening scene. Yu-chan has the most natural acting compared to her peers so this sort of devilish sister role is perfect for her. The titty fucking was great with how effortlessly she trapped that dick between her tits, definitely one of the softest-looking pair in JAV right now. My only complaint was that the cumshot was completely hidden inside her cleavage, so you’d have to use some imagination to get yourself off. Though to be fair it’s not that difficult with that face and tits staring at you.

Scene 2 – Sex Scene

The second scene is a mostly intercourse scene that shows the full glory of Yu-chan’s insane body in various positions. Sadly it ends with a super weak cumshot on her tits.

Scene 3 – Bathroom Titty Fuck (1 TF Cum)

Scene 3 is a bathroom scene very similar to that of her fellow Golden Trio Gojo Ren. A soap rub, a blowjob and then some titty fucking to completion.

This one was a bummer. Everything was almost perfect right until the end where they had to give us a super weak cumshot, which I’ve sadly come to expect from S1. Poor Yu-chan tried her damndest by leaving an opening above her cleavage to show the penis, so if you squint hard enough behind the mosaic you could at least see the formings of some semen above the tip.

Scene 4 – Cheating Outercourse

Scene 4 is another outercourse scene, this time with some flavor of Yu blowing and titty fucking our dick while the girlfriend is in the next room. There’s quite a generous amount of paizuri throughout the scene, but it ends with Yu jerking us off with her hand.

Scene 5 – Sex Scene

The final scene is another intercourse that ends in a facial cumshot. Overall an enjoyable scene with a couple highlights like how Yu-chan was stroking the penis with her underboob. I also liked the bit at the end where she gave a few strokes of titty fucking post-orgasm with her face full of cum.

Summary
This was a decent movie that sadly should have been great. The plot, the POV, the plentiful titty fucking and Tano Yu being naked for most of the movie. Literally everything was in place to create some masterful fap material, but S1 had to fumble it at the finish line. Twice.
Still this was a very easy watch, and something I’ll probably come back to get myself “warmed up” before a proper scene from Yu-chan.
