I actually watched J-series Ena-chan's 'The Genius Nipple Torture is Insane!' and the content was even hotter than expected!

First off, Ena-chan's genius-level nipple torture techniques shine. The scenario starts with the protagonist, who is arguing with his wife, being blackmailed by the schoolgirl Ena and then teased by her, with an intense focus on the nipples. From light scratching stimuli to firm kneading sensations, delicate handling with careful rubbing, and moist licking that feels soothing, the varied pace of torture techniques is non-stop. The technique of quickly flicking with the tip of the tongue is so pleasurable it makes you want to moan.

Moreover, there's a wealth of diverse play, including vacuum fellatio that targets both nipples simultaneously, handjobs while making eye contact, nipple cowgirl positions with tongue kisses, and nipple sucking that sends shivers down your spine while licking the ears. The thorough dedication to never neglecting the nipples leads to up to 13 ejaculation scenes, with an outstanding sense of immersion. The use of 8K equipment ensures high video quality, capturing Ena-chan's super cute expressions and subtle movements clearly, making it an irresistible piece for nipple masturbation enthusiasts.

However, in Chapter 1, the foreplay is a bit long, and the subsequent play feels somewhat messy, leaving the finish a bit lacking. Chapter 2 focuses on nipple torture but packs in too many other types of play along the way, which can break concentration. Chapter 3 includes a little nipple torture but is mostly standard sex, with some parts ending without a single climax. Overall, Ena-chan's reliable and erotic teasing quality stands out, but if the flow of play were simpler, it might have been more immersive. Still, for fans dedicated to nipple torture, this is content that can be thoroughly enjoyed.
