Just the tip

You close your mouth around the head of the big dick and suckle on it.

"Ooh yes that feels nice," her words excite you and you begin to use your tongue on her cumslit. "Philip have you been practising? This feels so good, no ones ever done this for me before."

Her moans grow longer and louder as she puts her right hand on your head and fondles one of her huge tits with the left, meanwhile on your knees you have one hand on her thigh and the other struggles to fondle her two huge testicles.

"They're heavy aren't they? They are so full of cum, are you ready for my load baby? You can pull out if you want but I want to put it in your mouth."
