Whatever girls you choose, shoot full body view when kissing and fondling. Not just faces. I am a boobs guy. I like to see boobs while  girls kiss and play around. 

Another suggestion is to have them wear clothing without bra. I find this really turns me on.

And also silky, loose clothing with straps that keep falling off their shoulders instead of just tight tank tops.

Let me know if you can incompensate these suggestions in forthcoming videos, I would renew the membership.
