I actually watched the collaborative work of Shiokawa Untan and Kannō Hana this time, and it can be called a masterpiece depicting the pinnacle of lesbian master-servant relationships.

What first amazed me was the process of Untan willingly descending into a lesbian slave. From the introductory masturbation video at the beginning, her masochistic nature already explodes. In the masturbation scene under Kannō Hana's training, the way she naturally spreads her legs into a crab-like stance at the moment of orgasm is irresistible. This is the instinctive reaction of a true masochist, sufficient to evoke an intoxicating excitement in viewers.

Kannō Hana's sadistic queen persona is also overwhelming. With whipping, spanking, toy training, strap-on fucking, and bondage training, she deploys a wide range of hardcore play, all of which stimulates Untan's masochistic heart. Particularly in the squirting orgasm忍耐 scene, Untan being pushed to the brink is portrayed realistically, highlighting the duo's well-coordinated acting.

However, one point that caught my attention is that Untan's obedience is too extreme. The attitude of apologizing and thanking 150% before being asked is indeed ideal, but at times it comes across as 'just routine.' Due to the lack of scenes where she is scolded or the masochist side reaches their limit in suffering, there is some deficiency in tension and drama.

Nonetheless, overall, as a serious hardcore S×M lesbian work where both parties are highly excited, the content does not disappoint. It's evident that Kannō Hana is very satisfied with Untan's reactions, and the entire work is filled with fervor. It's worth watching even for non-fans.
