Both are unbanned performances, but Arisaka Miyuki's "Unbanned Throat Vocalization Special - Explosive Piston Penetration with a Slender Head" is vastly different from Ishikawa Mio's:
What's the difference? Ishikawa Mio is Moodyz's gem. Although it's a 4P unbanned performance, in the promotional video you don't see any cruel scenes of the big bad wolf devouring the little lamb. Instead, everyone is like playing a game of freeze, remaining completely still so Ishikawa Mio can have her fill. But Arisaka Miyuki's performance...
It's an even deeper unbanned performance than "deep throat"!

It's terrible, really terrible. I'm referring to two aspects. One is the content of this film; the male actor practically shoved everything into Arisaka Miyuki's mouth—fingers, a penis, a dildo… repeatedly causing her to gag and cough up saliva everywhere. But that wasn't enough; to prevent Arisaka Miyuki from getting tired and closing her mouth, the production company added a teething device.
Frankly, it was really uncomfortable…
Arisaka Miyuki's reaction was one issue; I felt bad watching her suffer in this deep-throat release. Secondly, since her comeback, her body has become increasingly abnormal. She resembles someone with anorexia; her limbs are as thin as bamboo poles, and her face is sunken due to malnutrition. Adding to the problem, those two softball-like breasts stuck to her chest caused this actress, who was praised by the production company at her debut as "still a beauty in 15 years," to falter in less than 5 years—in every aspect.
Another tragic aspect is that this work released by Moodyz tells us that Arisaka Miyuki's dual exclusive contracts with E-BODY and DAS are gone. Moodyz uses the MIAA number to tell everyone that Arisaka Miyuki is just releasing new films; she's not even an exclusive with the WILL Group anymore:

Next January 5th, this film, "Her Sister is a Mazo Woman," will be the proof!
This is a release from GloryQuest, not a WILL Group production company. This means Arisaka Miyuki's exclusive contract has ended, and she's once again become a freelance actress, filming wherever there's a release...
Last time, she filmed too much and ejaculated too much, damaging her health and forcing her to leave the industry. I wonder how long she can last this time?
