Ok, I was the one that made the cutesy remark about rainbows and stuff lol, forgive me oh dear gentlemen!
Honestly there are 3 levels of FBSM and many different variations and techniques.
Versus doing all three like a tiered cake, I skipped the 3rd.
Im not one who is quite comfortable just slapping it out on the table, saying..."Level one is where I jack you off, Level 2 is where I give you a bbbj, and Level 3 is where I fuck your brains out lol".
So I just incorporate 1&2 together because it is basically a happy ending on both of the 2 things whether a lubed up hand or a warm wet mouth, with no penetration. And 2 is me having my way with you!
Hope this cleared up things on "the providers" part
