Hentai Boys from the hentai manga Bokura no Line by Sekiya Asami. Had it confused with another one by the same artist.

The third guy is just a side character (friend of the first guy) and didn't get to fuck so there is no need for "uncensored" in the prompt since there was no pictures of his censored dick. Of course, that means it won't be in the same style as the other guys' dicks.
