1st of all thanks for this picture. As you said you always try to make good quality video which can attract people so much. I am also agreed that in long hair world, no one can make better video than yours.
However, I want to suggest you for one video which I can simulate.
That video will be made with 1 guy and 1 LH model.
At 1st the model will come with her big bun to the guy who will sit on sofa and request him to oil her hair as her hair is little rough becuase of the sleeping with loose hair last night.
Then the guy will tell her to sit on chair and will loose her bun and start brushing it with wide tooth comb. Then he will tell her to bring oil bottle anbd small pot from where he will put some oil in pot.
After making her 3 parts he will start oiling her hair from left by taking tuft of hair. The oiling will be continued for 30 mins until her hair is fully oiled. Then he will tell her to hand over the brush and start combing her hair again to make the entire hair oiled. Then he will make bun and unbun her hair. He will also smell her hair by burrying his face and praise the smell of her hair which will make her laugh. Then he will make a tight braid because for oiled hair tight braid looks very hot and sexy
Later, he can offer her to shampoo her hair in the Professional saloon ( not in bathroom like subimal's videos) which will be followed by hair drying, brushing, smelling and cuddling her hair. at last he will make a huge bun and put a stick to hold the bun.
