With a girl like that, I don`t feel so bad when they give me head for over 30 minutes. Also, doggie can add something to the mix, and if they refuse to move, I make them say porn shit like "fuck me harder" ... "Ram that fucking cock in me" "Cum in my mouth" then I make them scream different shit, cause when they`re screaming it loud, they get a little more into it sometimes.
and my always favorite, I POUND THAT PUSSY (furniture permitting) like the Sun just exploded and I have 6 minutes till burnup.
