Paizuri only content gives me blue balls, but this premise is so absurd that I'm genuinely looking forward to the translation to laugh at rather than fap.
I'm someone that's fanatic for paizuri, and I can tell this author too. One thing that I like about artists focusing on something, is that they do it so much they create something unique over something that's always the same.
This guy is managing to come with many different spin-offs and techniques over the sole paizuri position. Having the guy train his penis muscles to make it go large to hold the semen as much as possible was something I didn't expect, but nevertheless enjoyed.
Thinking about how crazy and paizuri-focused this series is, I can already see a training arc where the MC is lifting a dumbell using solely his penis lmao, and I love it. The perfect amount of goofiness and horny.
