Luke is trying to explain to the guys what it takes to make a great scene. Looks and body are only part of the story, but the main thing is the attraction and sexual energy that the 2 boys have with each other. Roald and Ronny's scene together is the one Luke is using as an example, but soon enough the action is happening between Ronny and Alan Mosca. Alan certainly seems to have taken Luke's advice to heart and turns in a very hot performance here as he rides Ronnies cock every which way he can.
