throat swab position Tried ?

I had this position dont to me this past winter ,a friend wantd to face fuck be laying back over the bed with my head back , at first did not know what to expect from him , but looking up at his balls in my face while hes putting his cock all over my face and trying to get it down my throat without gagging was quite the experience...Any others tried this way ..looking up at a friends balls and ass getting mouth fuckd is interesting ,,
