The great thing about threesome vids with girls with lower mileage in the industry and guys of disparate attractiveness is that you can see how much better the female services the alpha male. It's usually not a huge difference, but it is an increment. Meaning, girls that give bad blow job just give slightly better bad blow jobs to the better looking guy, and girls that give good BJs just give a slightly better good BJ to the better looking guy. Cruicially it's always the one she goes for first that she's more attracted too, and she basically falls over herself to press up against the alpha here at the start. The next tell is who she blows first. She'll always blow the better looking guy first, and spend a little more time on him than the other. You might mistake thinking that she'll next let the better guy fuck first, but this is wrong. They prioritize BJs to the hotter guy. In this case the hotter guy wants to fuck her first so he does. But in this phase she'll always make more of an effort to blow the hotter guy when she's getting fucked by the beta. The other thing is kissing. She actively avoids kissing beta at about 27:20,
