SONE-650 - A trusted swimming club advisor suddenly developed sexual desire...

Just looking at her ass in the packaging shot shows off a seriously practical and beautiful hip line. She has a strong gaze, a perfect face, and a soft, beautiful butt. The swimsuit accentuates her curves and makes it even more erotic. The back shot of her pushing up the swimsuit is particularly noteworthy, and I loved how she flinched and succumbed to pleasure afterward.

It doesn't fall into the typical trap of stripping down halfway through; it's purely focused on satisfying swimsuit lovers. The director clearly knows what they're doing. First round by the poolside, second with lotion, third in a changed red swimsuit. The fourth scene features a more revealing swimsuit with multiple players, but I'm not sure it was necessary. Personally, I would have preferred a more proactive performance from the actress without that final scene. Taking off one star for that.

The slender build and swimsuit looked great, and I appreciated that they didn't use holes or toys during penetration – the way the swimsuit slipped down was a nice touch. My only complaint is that she was too passive and didn't put up much of a fight.

I was really hoping for something good, knowing even if she wasn't busty, the swimsuit would look amazing on her – and it did! But the content itself was a real disappointment. It was just a one-sided thing, with her not taking any initiative at all. I was hoping for a reversal, where she'd be the one going after him by the end, but that didn't happen. The ending was just some awkward teasing from the guys. It didn't showcase her at all. Such a shame.

The sex scene with Nakata Ippei, around the 46-minute mark, is incredible. The normal position while she's wearing her school swimsuit, and then the massive ejaculation that pierces right through it… it's a must-see for anyone with a thing for getting a swimsuit messy. That scene alone is worth a rewatch.
