lumbar lion

huge masculine cock that packs more power then a haymaker from Kimbo slice.... so big that not even the most interesting man in the world has it....... a cock with pube flow better then rob ryan.

you go up into heaven and dumb out a lumbar lion and god immediately falls to hell and it is now yours and you make a law of prancing naked women to suck and clean your lumbar lion all day long.
