From what I could have translated to English along with my own edits and paraphrasing to fix some translation bugs and add extra flavor from the OG, it reads as follows:

"Effect of the lewd crest"

-Sensory Receptor Reset: Resets her nerve receptors at regular intervals (No matter how many times Kaga climaxes. her senses will never dull, she'll always feel it in full)

-1st time forever: It returns her senses (body and mind) to that of the moment of she 1st climaxed so each orgasm subsequent she feels/experiences is always fresh and new as if it were the 1st with no diminishing returns.

-Neural Recovery: Completely repairs the neural tissue that does get exhausted by the extreme pleasure

-Restless Joy: Getting tired or even Kaga getting used to the sensations is prohibited, in short she can't even go mad/crazy or even adjust to her predicament, fullly conscious and aware of every sensation and her own helplessness. (trapped in her own mind, her own body used as the tool of her torment)

Effect 2, Forced Awakening: one of the following effects will activate at random should Kaga faint or fall asleep.

-Intense Torture of the Clitoris, Breasts and other erogenous zones

- A Simple awakening without accompanying pleasure (to add to the anxiety)

-A Simultaneous slam/release of all the pleasure she has experienced up until this point since the moment the crest was carved onto her (every moment of pleasure and climax she has ever felt, hits her all at once, if she falls asleep or faints again, there is a 1/3 chance she experiences an even worse version since she is constantly being pleasured and another 1/3 "wake up" option also contributes to this as well which only adds to how hard & torturous this will be to her continuously again and again).

My wife looks lovely like that~ Only reason I cared to do this. Now if only this crest could be put on the other kitsunes...
