MNSE-021 - First Time Meetup with a G-Cup Slut

I bought this thinking it was an amateur-style video and regretted it... Even ignoring the short runtime because it's the 'streaming version,' they spend the first half flirting, move to the bathroom to flirt some more, mess around a bit, and then when they get to the bed, the actor just casually pulls out a micro bikini for her to wear... Even after penetration, the actor seemed to have zero enthusiasm, leaving me feeling unsatisfied. Honestly, what's the point of filming this as an amateur-style video? Wouldn't it have been better as a themed production like 'My Girlfriend...'? I'm only giving this rating because it's an actress I like; if it weren't for Sana Sanada, I wouldn't have even bothered writing a review.
