The Kabosu Pine [English], an hentai doujinshi parodying the Kabocha Wine series, by Trump
I briefly wondered if that wasn’t a rewrite, some oddities with naming (“LL”?!?) or typesetting made me suspicious. But apparently, we’re good, this is an actual translation. If you wonder, this is made after a series called
The Kabocha Wine.
Long story short, a tall and plump clumsy girl makes her smaller boyfriend embarrassed in public, but they’re having good old sex all the same in private.
There’s very little censorship, as of expected of an old-school looking h-manga ^^
