YEKD-004 - Obscenity in every curve, a relay cum-inside party with 4 different beauties

This is my first time watching this series, and in a word, it's like E-BODY—no useless chatter, just pure focus on sex. The cast is full of alluring actresses with a strong mature vibe. The runtime is a long 240 minutes, so naturally, each couple gets about 60 minutes of playtime. Both the actors and actresses are sweating and giving it their all, but all four couples use so much technique it feels like a 'sex skill competition,' which came off as a bit too performative. All four actresses squirt and get creampied, which seems to be the theme of the work. Even Reiko, who I'd never seen squirt before, did it perfectly. However, it felt like they were being forced to do it, which was a bit painful to watch. Watching this, it feels less like sex and more like watching a contact sport where flesh slams against flesh.
