LULU-381 - Description of sexual acts involving a sister and her involvement in a sports club. Kitaoka Karin.

It's amazing to see a pro athlete wearing high-spec Mizuno gear descend into this kind of depravity. The stretch and moisture-wicking properties that are supposed to enhance performance are really coming into play here (laughs).

The way they tease with the clit through her panties, so you can see the fingers and rotor moving, is a major plus. She's constantly cumming, so the plot holes don't even bother me. My only complaint is the shaky camera work. Too many cuts between wide shots, close-ups, her face, and her crotch – they should've used split-screen. And during the toy play in her casual clothes, they barely show her face. Isn't the title supposed to be about butts?

Honestly, this was a mess from the start. First off, why was the sister's face blurred? Karin's acting was just…rough. Leaving her alone with her boyfriend she just met felt so forced, and her just laughing and accepting him touching her in *those* places? Didn't do anything for me. I was really looking forward to this, but my expectations were immediately crushed. They could have made the athletic cosplay way more erotic, it's such a waste. The actresses were pretty, but it feels like they could have done so much more.

Tracksuit uniforms are all about the belly button. Seriously, I'd love someone to just dig around in there.

Karin in sportswear getting 'massaged' into some erotic stuff. The costumes change, but the actor's actions don't. The whole thing felt a bit bland until the end. They could have really leaned into the sporty look and Karin's assets.
