In the Greek alphabet, there are Alphas, Betas, Deltas and Gammas and many more letters. This guy isn’t prime sexual material, but he’s still above average. The two with him are at a lower level than him. So, is this a Beta with two Deltas? Looks like he’s taking one apart with very little effort. Her teammate hopes to even it up by throwing in some more thrill.
Personally, I see these Deltas as toast in short order.
