It's quite a power trip, having your young, straight assistant bound, rock hard, asking you for permission to cum. Think about it! Keith consented to submit to Rich's groping and fondling, and Rich loves it. He licks and sucks on Keith's cock and balls until he's hard and aroused, then he gently strokes him till he's asking for permission to shoot a load. Then Rich uses a rubber pussy and with slow, teasing, gentle strokes takes him over the edge.
