I saw it in many years ago. It's probbaly from 2000 + years.
The male actor is most probably Michael Stefano

The girl I can't remember, but she was slim and blonde.
The plot was: Stefano is sitting on a chair is some office at night and blode is giving blowjob.
Camera and style is more raw, no super staging and lighting - more home video feel.

In one moment, girl is so tired, she will fall asleep with his dick in mouth and stop peforming :D
Actor has to slap her gently on the face and she wakes up and continue...

After that they move to difefrent room with sofa, and have anal and ass to mouth.

Do you remember what movie it was and hwo to find it?
