There are few who offer it outright as an option,, but curious if any of you have been with a provider who has obliged in the heat of the moment. It’s a super YMMV thing in my experience so feel free to send me a direct message!
I was with a sweet girl from VIP one time. I was sitting on the edge of the bed. She was kneeling on the floor in front of me giving me a blow job when she put her fingers underneath my toes and motioned for me to lift my legs. I thought she just needed to reposition the towel so I lifted up my legs a little bit next thing I knew my knees were behind my head and she was rimming me and licking my balls
I've mentioned before that I'm happy to offer it WITH a dental dam and completely unwilling without. Some will argue that it doesn't count, but receive this info as you will! Enjoying a pleasurable thing that isn't offered by every provider, in a way that reduces the pleasure minimally, is still pretty cool imo.
