Ilb
Instant Loss of Boner
It was evening time and I was hard as a rock because of the girls gone wild commercial that just came on, little did I know that I was about to expierience an Ilb. The large lump in my pants then proceeded to fade away as I recieved a nudey pic from Bailee, the 250 pound girl that seemed to have a freak crush on me.
