My mistress lived in a flat on west end road opposite the train depot one above the shops, she lived on the top floor and had a concrete enclosed balcony on the rear.
Her landing neighbour was a mature guy on his own, they were friends before I met her and often spent time together.
One evening, they were talking, about sex and fucking and he was getting hard and horny he told her he would love to be sucked off by another guy . She replied well then just use Charlie in which he replied it's my first time with a guy
she smiled and said that's OK, he's used to swallowing but it will have to be on the balcony outside.
On the balcony she had two plastic garden chairs, she ordered me to strip naked and kneel down on the cold concrete balcony.her neighbor she ordered to drop his trousers and sit. He was a bit hesitant at first and when he dropped his trousers he had a huge erection.
O my she said someone's excited about using you Charlie, I think you best take care of that so i shuffled over and went to work on her neighbor's cock while she sat in one of the garden chairs smoking her fag.
After not very long and some loud quick moans, her neighbor came down my throat quite a juicy amount. With his erection gone, I began tonguing his balls.
My mistress flicked her hot ash onto my balls as she said to her neighbor, I can see you enjoyed that
He smiled a rather ashamed naughty smile and replied it was fucking amazing and so much fun. Then he began pissing into my mouth with his limp cock growing and getting a little stiffer with him now hard and excited again,
I sucked his cock as he chatted, and she flicked more hot ash on my balls. She said you know Charlie is available any time you are in the mood to use him.
Just knock on the door anytime, but I will have to watch, she said. Now let's go back inside, it's a little cold. Charlie put every thing back tidy on the balcony and say thank you to our neighbor for feeding you his lovely cum which I did.

So that was how she introduced me to her neighbor .who after that evening liked to visit me at least a couple of times during the month when he was in the need. She always enjoyed watching me kneel there naked, even in winter in the rain and the snow on the cold concrete balcony servicing her neighbor's cock and swallowing his load And to be truthful, we all knew that I loved it.
