@mruggeri2 it doesn't matter if the author drew rape group mind break porn(spoiler: he did lol) What matters is the target audience/age restriction of this manga. Now granted
Tomo-chan wa Onna no ko! is web only so theoretically he can do whatever he wants without worrying about the publisher. But a sex scene would still throw the ENTIRE thing into 18+ category with all the accompanying legal hassle... and profit loss.
They will probably end up kissing after screwing around for 10 chapters, but don't expect them to EVER fuck.
