During an act of fellatio,the woman lies on her back on a bed, couch, etc. while the man receives oral sex. During this the testicles will cover the woman's eyes. During deep throat penetration the testicles will 'smack' the woman's eyes repeatedly.
Ex: Yo dude I had
Jessa laying on her back with her head hanging off the couch and I
throat fucked her and gave her
the Arabian Goggles.
