dog in the bathtub 

Trying to put your penis and balls into a woman's vagina. Trying to keep them in is like trying to keep a dog in a bathtub.

That bitch was so loose, I had to put the dog in the bathtub.

It is what happens when Number Two (or five these days) inserts his enormous steel plated testicles inside an unsuspecting minx's beeeeeeehind and shakes them vigorously. His balls give off such friction that authorities have often feared another Chernobyl type incident.

After waving to the crowd, Number two reveals his massive testicles and pops them fair into the arse of Mimi McPherson. While she smokes crack. And her crack smokes as well.

Dog in the Bathtub 

When you tactfully place your balls in her ass while having vaginal intercourse. Tactful is the key word; washing the dog in a bath tub is never easy.

I thought I would have a struggle but putting the dog in the bathtub came naturally to her! #bestinshow
