Once had a ML who I had seen a few times previously who was a very raunchy lady and liked to try things ask me to COF.
She was a lady who on entering the room was just full on raunch and tease, sometimes massage but generally touch and it was two way. She had previously had me cum on her belly, another time on her boobs but never did I expect here to ask me to cum on her face yet she did. She played with me, got me very close and then asked, knelt on the floor and asked me to finish myself on her face and she did seem to genuinely enjoy it.
Saw her a few more times after that and she never asked again, but did keep the other raunch aspects up but never was there any oral on me, FS or anything - she just loved the tease.
When Covid came along she packed up and moved as teh shop shut down - never seen her around since
