Oooh, those realistic bodies! (Although the guy is still rather over-endowed) This makes me wish there was a tag for this... and, you know, more comics in this style to support the need for a tag, heh.
I like the touch of normality and every day life this story has. It's refreshing to see their nervousness until they give in to their shared lust in comparison to the normal hentai protagonists who just go for it...
What is even more weird is how quaint it is! Condoms at 500 yen, boys have their own secret bases, teenagers acting so shy and demure and of course the art style.
Am I transported back to the 1980s before the internet is invented and everyone had to make do with secret bases and can't access porn? Didn't they have an abstinence drive though which could explain the 500 yen condoms. A bit pricey if there are sold apiece.
