Umlaut House:

Pierce has a new boyfriend: Alex! What a cute couple the pandafox and bobcat make. Alex is a bit of a jock, and Pierce is... well... kind of a waif-thin sissy. Be nice to our Pierce, Alex!.. Well, you don't have to be too nice.

Visit Umlaut House to see the inspiration. Relevant chapters are "Bisexuality and YOU!", "Alex Vs. Pierce's Brain", and "Pierce Goes For It".

I know the heads are "squished" looking, but that's how the characters illustrated look in the comic. Blame Allan Ecker, not me! : o)
