2 Part Technique - One thing you can count on against an opponent who doesn't know how to properly defend against the mount is him voluntarily giving up his back to escape. Let him. Ease up the weight of your hips and give him room to turn over onto his knees. Immediately look to finish the Rear Naked Choke by reaching across his throat, grabbing onto your bicep, and locking the hold with your hand (palm facing you) behind his head. If he raises his hips up, throw in your hooks and fasten the Seatbelt Control until he gives up the opportunity for the choke again.
