M.P.U

M.P.U. is an acronym for Mounted Practice Unit. This unit contains a dildo with a shoulder mount that surounds the head. The M.P.U. has a motor that moves the dildo back and forth. The point of this device is to practice oral sex with a guy.

I suck at giving head, I need to go home and practice with my M.P.U.
