Spastic Centipeagle
Or Spastic Centip-eagle: When a male transexual who is receiving anal and giving head and two hand jobs has sex with another person who is also giving head and two hand jobs and so on and so forth in a linked series. If you can picture in their head and arm movements, you'll understand why it was given the name Spastic Eagle. Link two or more people in a chain performing Spastic Eagles and they will thusly form a Spastic Centipeagle.
Look at these twelve people in a chain doing a glorious Spastic Centipeagle.
