Otoshiana (“Into The Deep Hole”) [English], by Shiomaneki
For me, an old-time Shiomaneko fan, this is a dream release ^_^
Imagine: a teen is caught buying a tenga onahole by a female teacher in the sex toys isle of a shop (clearly, the educational system is failing: he didn’t ask himself how come he was meeting his teacher there), and with an adorable teasing and horny look on her face, she takes him to a love hotel to show him how real sex is done
19 pages is short, but when these are Shiomaneki contents, it looked enough to have a great time reading :3 The small amount of censorship, the drawing quality, the expressions on the woman’s face, it made for an excellent release
Thanks a LOT to hive-san, I’m grateful!

Page 18 ….. BWAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! (won’t spoil it for anyone who wants to discover it for themselves).
But Seriously, Though … is anyone questioning just how Oda-sensei and Ishizaki ended up in a hotel, considering their respective ages, and the likely possibility that the hotel check-in staff at least suspected the reason they were coming there (say-no-more, say-no-more)?
In The End (and surprisingly, it seems to be mutual on both side):

This is Japan. You could enter with a five year old girl with a pair of horns protruding out of her forehead and the staff would still not ask any question.
Ohhhh-hohohohohoho ….. don’t have time right now to make a “young male” version of this, but the idea should get across clearly enough:

Welcome to the 21st century. I’m in America and I can check into a hotel in Japan via the Internet. She could get the room via her phone. Or she could check in alone and boy-toy could just wait outside until she has a key. Judging from all the traffic these places get in other stories, discretion is probably quite valuable.
Also, these rooms aren’t always used for sex. The population density in Japan is insane, sometimes people just want a room without other people in it. Ever watch the anime Planetes? In an episode, a couple gets a room just for privacy and no one even reaches for the cosplay kitty ears. Sure, most people have sex, but occasionally a body just wants somewhere to sleep or talk privately.
One could argues that one is dealing way too much in hentai if or when hotels are automatically associated with “sexy time”. As Pavlov rightly rightly said, that is not the case in every instance – whether in real life or in h-media. And yet I’ve seen some works where one or more of the characters did carry a change of clothes – obviously, someone leaving a hotel wearing a school uniform could rouse suspicions (know-what-I-mean).
Too much meat for the joy can.
Still her beaming, bespectacled face on page 1 is the stuff avatars and pic posts are made of.
