This thing is all about immersion. Leaning forward cowgirl is a champion position. The Girls need to be trained / coached up on the eye contact aspect . It makes the entire connection so immersive and powerful.
Also the belly gyration on a cock while in cowgirl is so incredible and mesmerizing. Every video should have these aspects in it both laying and seated.
The BJs should always start with teasing and lots of eye contact. Kissing around the cock and then slowly going up the shaft with the tip of the tongue with an unbreakable gaze.
Then slowly starting to wrap the lips around the head and then gradually going deeper and deeper on the shaft.
More attention to beautiful lacey lingerie accessories (thigh highs, sheer panties where you can see through and see her beautiful flower) is a huge piece that would spice up new videos as well.
Girls being more intimate and staring deep into your eyes and saying I love you can also be intoxicating.
