Proxy Sex? Doppelganger/lookalike sex?
If you take advantage of a changelings shapeshifting ability, or have a magic copy/clone of someone you like to do what you want with?
Or when you have a pony dressed up/disguised as someone you'd like to have sex with.
The English language could use more words to describe these situations.
Also, I thought there were 16 + thoraxspike tagged images. I wonder if it got changed recently.
Oh! Sporax is what its called now :D
