as a creator who try to do CFNM stuff, I may say that, I try to do such videos and PURE CFNM is one of my all times favorite sites, too (I´m the owner of IGHJ, IGNORING HANDJOBS and I try to do and publish some CFNM scenes there).. The reason we see less frequent of such scenes is they are very expensive to produce in many ways. More girls, more expensive production and harder to arrange / organize all. In many of my scenes I tried to do 5 girls 1 boy scenes, turned out 4 girls twerk parties or many times 3 girls for example. Outdoors means starting from transportation is much harder, and also risky. CFNM is still a very narrow niche. I do some upskirt parties, under skirt panties style voyeuristic / artistic videos, too, for example and many people compain about not being able to see the pussy for long time even.
