pterodactyl
Harnessing yourself and your partner onto a ceiling fan in a superman-like position.  Turn the fan on and spin around while having sex.  "CAWing" in their ear as loud as possible is essential.  Feel free to unhook the harness falling to the ground with all of your weight on your partner.  Scratch their back with your talons if needed.
My girlfriend thought the pterydactol was fun until I started "CAWing" in her ear as loud as I could.  But then she laughed when I scratched her back with my talons.
