similar to a ball gag, but with a dildo instead of a ball. It is to be placed in one's own mouth for self inflicted sexual torture and for erotic stimulation. Often used by closet homos and S&M enthusiasts.
When I get home, the first thing I will do is strap on my mouth ween!!!

Since I bought my mouth ween, I'm never lonely on Friday nights!
