A great way to jack off your partner, who has a big whopper of a dick.
Not everyone has a big cock, but for those lucky few who do, this is a great way to get them off.
Make sure both hands are well oiled.
Grasp that monster sized dick with both hands.
Then move both hands up and down along that big pole, in a typical pumping motion.
Keep your grip tight.
You can change things up a bit, by switching the position of the hands, or in how you stroke that thick piece of meat.
