I had a one year relation with a girl (I was 42 she was 36) and, of course, I started talking also about my kinky sides, to find out whther she could be interested.
To my surprise she showed herself very ibterested, but not in submitting herself, much more in having a female slave available.
So I started to talk to her about caroline ... she wanted to know every detail and many times we had terrific sex talking about caroline's tortures and humiliations.
After I while I proposed to her (Sabry) to actually share the slave and enjoy it together. She accepted and, while I was on a business trip abroad they had the first telephone contact and arranged for a date. caroline was at the sea side with her children ... Gabry visited her late in the evening, when the children were already sleeeping and enjoyed a slave for the first time, whipping her softly, having her own feet licked and adored by caroline and experiencing for the first time oral sex by another woman.
The next day she called me and told me all details about their meeting, howmuch fun she had and asking me to go to a sex-shop and buy some large dildo she wanted to use on the slave.
Few days after we had our first threesome and we enjoyed the salve together sexually and sadically.
So we found out that a couple of 2 dominant persons could be very satisfactory, provided we had a slave female to enjoy and use.
We played many more times with caroline until our relation broke off, for completely other reasons (SM is not everything in life).
Still we got in contact again a couple of years later and she asked me whether she could borrow caroline from time to time, to enjoy her, alone, or with her new BF. caroline and I agreed and she was invited a couple of time to dinner by Sabry ... that is, to serve dinner and after dinner as a slave
Other times we met again, alone or with other friends, just to enjoy caroline together.
Besisdes this personal experience I have known other dominant couple who enjoyed very much their life together and any chance of having a slave as a common toy and pet. Mark and Helen, for instance, who rented caroline once in a while as a gift to each other...
Therefore I believe that two dominants can make a very good working couple and enjoy BDSM atogether a lot.
