Black girl on girl blowjob

I work as a luggage Porter in a top London Hotel A few months ago I took two suitcases to a nice looking very shapely black lady in her thirties she was wearing white skin tight slacks showing off her big round bum. She noticed me staring at it. she just smiled and asked me to call back later for a tip. I popped back later, she asked me in she had a short yellow skirt on that showed of fabulous muscular legs I was waiting for my tip when she hitched her skirt up to expose a pair of pink cotton knickers, she smiled and slowly took them off and handed them to me and said in a thick American accent I have brought myself off in them she winked Go and enjoy them I certainly did I went into the next empty room and wanked my cock sore inhaling the gusset of her sticky musky knickers, they were heavenly.
