Ore Senyou Hisho [English], an hentai doujinshi parodying the Gundam Build series, by Sunagawa Tara

I never watched Gundam Build, so I can only vaguely comment on what happens. A strict-looking busty teacher tries to get leverage on a team building gundam toys for competition or something, and, hentai oblige, it implies deflowering him and offering him awesome sex.
Honestly, we can ignore the scenario, it’s just good sex basically, lol. Not too censored, a pleasant rather crude and explicit drawing style, see for yourselves
(Side note: I ran a light retouching on the pictures, to smoothen the spotty backgrounds and adjust levels.)

I’ll be thanking Mongolfier for this release

By the same artist, I also share Midara-No-Jyu, Kaerimichi (“On The Way Home”), Prostitute Dancing Priestess, In-Jyu and Chocolatribe.
