Aoi Yamamoto is 20 years old. Determined to get his first girlfriend, he joined a Nihonshu Club...only to find it chock-full of men.

I loved it. It's a series that's a bit wacky but full of respect for others. The characters are so cute. I'll have to check out the author's other works.

Book titles & chapter numbers

Rating: N/A

1st book in series: 愛しのXLサイズ
2nd book in series: 愛しのXLサイズ・続
3rd book in series: 愛しのXLサイズ・続々
4th book in series: 愛しのXLサイズ・続々続
5th book in series: 愛しのXLサイズ・続々続々

Book 1 has chapter numbers 1-5.
Book 2 has chapter numbers 1-5.*
Book 3 has chapter numbers 1-5.*
Book 4 has chapter numbers 11-15.
Book 5 has chapter numbers 16-20.

*I assume the 2nd book is the start of the sequel (zoku) and so the chapter numbers restart from 1. That would mean the chapter numbers in the 3rd book are a misprint and supposed to be chapters 6-10.

With a premise like this, how do you take any of this seriously? You really don't and the manga is aware of this. Big dong dude and an absolute idiot, what could possibly go wrong?

Shout out to Yamamoto's friend who said getting sun on your ass improves mood, like wtf xD There are so many laughs to be had here.

something to appreciate

This was a cute, enjoyable read. Very smutty with a really dumb virgin uke x a nerdy but hot virgin seme. Idealized, but honestly hit all the good notes with the sex scenes (vocal uke and a passionate seme make me weak).

I really enjoyed how Kobayashi was constantly checking in with Yamamoto to make sure he wasn't in pain and was enjoying himself during the sex. Never got old (especially with Yamamoto communicating that it actually felt good nosebleed). I'm always appreciative of good sex etiquette in my mangas and this is one great example. Communicate with your partner!

Whew now that's some anaconda

For a story so vocal about big dicks and their application this one actually has some quite innocent and romantic moments, most of which stemmed from the gullible nature of the country bumpkin uke and the gallant and attentive habits of the ikemen seme. It has its own unique charms that way. The fact that the uke was so adamant on pairing the seme with a girl, though understandable given his dim wits, was a bit much, but I'm glad it was finally firmly shot down once and for all by the seme in the extra chapter. And don't forget about the smut, it plays a big part in the story and is honestly pretty good even if the art isn't the prettiest of its kind. I do wish a better cover for the tankoubon was chosen though - the digital cover used for the series during its original run was amazing so it's not like the mangaka isn't capable of drawing good cover arts.
