Speaking of the facial part , for me it is more about the girl being focused on the different dicks ( not more than 4 or 5 ) , and playing with them simultaneously :
Holding one cock in each hand , while sucking another one or 2 ( double blowjob etc) , while the sperm ( not too much ) , is running slowly down the chin ...
Some very horny girls will take three or four ( ! ) cocks into their mouths , and when the cocks are not in the girl´s mouth , they will gently caress the girl´s cheeks or breats ...
Also , the girl should not be submissive , but in a playful , joyous mood , and can even be a little dominating , guiding the scenario.
DISCLAIMER : This is NOT about bukkakes , messy facials and faces plastered full of cum

It´s more intimate and erotic .

It might also be that the rest of the scene sucks , but if the facial scene is up to my expectations , the scene deserves a special place for me .
