Sharring anna with beautiful Black Domme

I met Carmen (not her real name) on CL. She seemed to be an experienced Domme who lives in Washington DC. She was looking for a white woman to enjoy and as we emailed and then chatted, I told her about anna and her interests definitley shifted from me to anna. After a few phone calls, as date was set for anna and i to travel to her apartment in the city, about 2 hours away. anna was to be Carmen's toy and I was there to watch and for safety reasons.
As we drove the 2 hours, anna was nervious yet excited.... anna has never been with a Woman of Color before.
Once we arrived, the apartment was nice but modestly furnished. Carmen opened the door wearing a a robe, heels and heavy makeup. She smiled and invited us in. Carmen's eyes were all over anna and Carmen motioned for us to have a seat. We all sat and Carmen explained the rules:
anna was to do everything that she was told... if she did not, we were to leave immediatley and never return. I was to watch only. I could not join but i was allowed to masturbate if i desired.
I looked at anna and she nodded. Game on!
Carmen told anna to strip completly. Carmen watched as anna removed her clothes. Carmen then told me to remove everything except my panties. Now, anna was naked and i was in my panties only. Carmen removed her robe and was wearing a corsett with the top half her breasts exposed.
Carmen then examined anna like she was a calf at auction... probing and looking everywhere.
Carmen then tied anna's wrists behind her back and twisted and pulled her nipples. All of this as I watched!
For the next 4 hours, i watched as anna was totally used by this very experienced Black Domme! Carmen came many times yet denied anna relief. Carmen pointed out to anna that i was masturbating to anna's use.... this embarrassed me a little and shocked anna a bit.
To see Carmen's black skin in contrast to anna's milky-white skin was so erotic!
Carmen was an expert at flogging a young pussy, ass and breasts! Carmen also was a tease with a strap-on. i actually asked that she do me at one point! Carmen cherrfully fucked me good as anna watched!
By 2 am Carmen and i were spend and anna needed to cum BAD! Carmen used a strap-on and entered anna while tugging her nipples until she finally came hard! We were all spend and fell asleep in the queen sized bed. I was awaken in the eraly morning by Carmen taking anna's ass with a strap-on. i could not resist and masturbated as Carmen pounded anna.
Later, we all showered, dressed and made plans for another "date"... perhaps an entire weekend!
