Take him now!

You surge up and pull him tightly, making him yelp. With on hand you hold him close while the other grabs his dick and starts to jerk it firmly but slowly. "Well, that was sudden Sir." He says.
His dick turns rock hard, he wants this as much as you do.

You stop holding him against you and move your hand down to his ass and start to tease his asshole with you fingers. He stays pressed up against you, especially his ass which is now practically grinding your hips.
