This is 100% true story of when i was working in peoples houses years ago.  i priced up a job for a very horny young black woman who just oozed sex !   she was quite cuddly with huge boobs.  anyway i started the job and she was always dressed very sexy. leather mini , stockings always showing, cleavage and lots of makeup.  she was a proper flirt too.  it turned out she had an older white b/f who had bought the flat for her and she was doing it up with his money.  i was only there a few days and she was getting flirtier every day. flashing stockings and thong up her back.   on the last day her b/f came round and and they were all over each other.  and she was flashing a pvc thong and stockings on purpose at me.  then they went into the bedroom for ages.   when they came out she had changed and said they were going out,  thanked me for all my work and told me to let myself out when finished.  after i cleared everything up from the kitchen where i was working, i checked the other rooms. so went into the lounge and was shocked to see she had left her stockings and pvc thong on the sofa.  course i had to investigate ! lol.    by now i was feeling very horny.  and i couldnt believe it, she left the thong, gusset up and it was completely full of spunk !   now if that wasnt left for me on purpose i dont know.   by now my cock was rock hard and throbbing.    so being a dirty bastard i took them into the loo and wanked my cock untill i too added  lots of my spunk to her gusset !    i then put them back where i found them and left.   i know its not a story about a fuck, but still turns me on years later.   looking back it was game on and i should have fucked her .
