His snaggled toothed girlfriend can barely feel his cock so she keeps asking for it harder but she doesn't seem to realize that there is only so much you can do with 3 inches..
He tries to get her to say "you luv black cock" but she doesn't comply... so he thrusts even harder which leads to her having orgasmic spasms in a retard-like manner.
Apparently getting your dick hard for a hot pornstar isn't as easy as you'd think. I'd probably blow my load before even getting my cock out of my pants.
