Hair? I got a couple of stories. Never thought I'd like stubble on an FBB, in session or out, but here goes.
No names here, but the first one is with a favorite well-known FBB that is all but retired. We exchanged emails and a phone call about my usual session, involving role play with her being the Jungle Amazon and me being either a submissive or captured Tarzan, with me wearing the usual animal print thong. She loved the idea and surprised me when I went to her hotel room and she was wearing an animal print string bikini and wild, kinky hair. I went to the bathroom to get undressed and freshen up and the session began immediately, with both of us growling like animals trying to get each other into bear hugs. In trying to "fight" our way onto the bed she began licking and kissing my face and I did the same to her, when I felt stubble on her face. I was shocked for a second or two. Then I was even more turned and began to lick, kiss her shaved underarms and other areas after our animal prints were all but were ripped off. There was comical "me Tarzan you Amazon Queen" dialogue, growling and mutual holds and sensual pleasuring. She did have a deep voice, but feminine, and I never talked to her about her facial hair. After the session we complimented each other and she said the scene turned her on, and that I began to lick and kiss her face and underarms. Saw her a couple of other times and she was / is very imaginative, sexy and a hell of a lot of fun.
The second story is about an FBB / dominatrix I was a regular with, became friendly (not romantic) and she asked me to "create" stubble. She's retired now but I was in DEEP subspace with her. She was very intimidating physically and mentally. In probably the last session I had with her we met at her hotel and told me more about a relationship she was getting into. He didn't know about her alter-ego. We began a slow session of me undressing her, worshipping her feet and legs. (As always she never removed her bra.) She then fluffed up three or four pillows, laid down in the middle of the bed, spread her legs and said, "I want you to shave me," pointing to her pussy. Stammering I said are you sure. She said, "Just do it. I trust you. The razor and cream are in the bathroom."
I went in, remembered what my old time barber used to do when he shaved my face with a straight razor. I got one of the towel nice and hot with water, rang in out, and brought it along with a few other towels not to make a mess in the bed, plus the razor and cream. She was in a strange mood. I spoke a little bit, but she was mostly silent. When I was done I cleaned her off and got rid of the towels in the bathroom. When I came back in, she smiled and said, "You did a good job, my pet. Come here and pleasure your Mistress." I did what I was told, she then got up and posed for me, talking seductively and ordering me to pleasure myself in front of her. Session over. I left amazed and confused as to why it happened.
We stayed friendly for a couple of years after she retired. We met for dinner when I was in her city. I finally asked her why she had me do that. She said something to the effect that she knew her career as a sessionette was ending, and being clean shaven was a symbol of that... a new start. I found out the relationship with the guy didn't work out, but last I heard a few years ago, her business is thriving.
