I’ve seen you post this fetish a few times now.

Unless the provider offers BBFS , or has an SO this is a fetish for BDSM players it’s called, creampie & many cuckold‘s will allow this. If you don’t get a huge response it’s because the majority of professional providers care about their safety & lower their risks of contracting STD’s, or possibly getting pregnant. As a lifestyle Domina I suggest you go to another site to fulfill your fantasies. Fetlife sounds more, like a better option.
