Tag is one of the most well-known translated hentai mangas, and it highly deserves it, so, well, even if writing it may look contradictory, I hope you already have this one But if you didn’t know Tag yet, well, here’s an excellent occasion, take a look
The manga is about young students whose sex life is spiced by forced exhibitionism, but – obviously – they discover they bloody like it ! The scenario isn’t bad, the old-style graphics are nice :o
It’s been released by Munyu Heavy Industries, thank you very much!
–Update: excellent news, the present share has become obsolete!
From now on, please follow that link for a new version of the manga, now fully uncensored, and re-translated with many an improvement
