A stinky willy is when you masterbate on the toilet whilst having a shit and fall face first onto the floor shit on your own cock and just as you are about to climax you get a wiff of your shit and climax in your own mouth
when your fucking doggy and stick you finger in her asshole and fish out a piece of shit then plug her noise with it while covering her mouth with your other hand so she has no choice but to breathe in poop through her nose.
at school today this girl asked me for a stinky fingy but the hall monitor walked in.
