A while ago I saw a Tumblr pic of Mrs. Valentino being fucked by Dipper. I hadn't really considered her as someone sexy until I saw it, but then my friend xxmercurial-darknessxx started running a poll on who Dipper should be paired with, and she was on the list (I voted for her and she won, the final comic can be seen here: http://xxmercurial-darknessxx.tumblr.com/post/134862059096/xxmercurial-darknessxx-comic-robert-staceys). It turns out he'd included her in the poll based on the same pic I had seen before. All of these events kind of coincided enough that I decided to do this pic of Dipper and Wendy sharing Mrs. Valentino.
For those who aren't familiar with the show, Mrs. Valentino's son being referred to here is Robbie, a teenager who dated Wendy for a while and whom Dipper sees as a rival.
I hope you guys enjoy this pic! I'd love to do more Gravity Falls stuff in the future, though I'm still deciding how I want to approach the style. Here I kept the faces mostly in the show's style (with only a few tweaks) and tried to keep the bodies more realistic. When I ran a poll earlier on Western cartoons, it seemed most people wanted me to draw them more anime-style. If you have an opinion on this, especially as it relates to Gravity Falls, let me know with a comment!
