Hunks Workshop is a yaoi video game but it's not a "BL" one. This game is geared more towards gay men and features muscular guys. This type of artwork is often called by the name "bara" among anime fans (but not necessarily in Japan).
The artwork from this game is by a great artist by the name of Masanori. I've been a fan of his art for a while and I definitely encourage you to check out his site (linked in the sidebar under "Non-Worksafe Links") if you haven't already.
Also, if you want more info on the game, check out the official website of the company behind it.
