Circus Seal Seesaw

The act of two batty boys (gay men) alternating bobs on each others cocks in a sea saw like fashion. The act is perfected by the mens heads bobbing up and down on each other in a motion resembling a circus seal.

John said: Your not going to believe what I just saw?
Ian said: What?
Jon said: I just walked into the back office and saw Otto and Dan going down on each other like a Circus Seal Seasaw!
Ian said: Uhhhhhhhh...I feel bad you had to witness those batty boys working each other like that! I didn't even see them and I can't get the vision of a Circus Seal Seesaw out of my head!
