By then I was on flexitime and could have long lunchbreaks and they worked from home so could meet for a long midday session. I got a call one day and...they asked if I would like to pop over and see them - little did I know what was in store for me!I arrived and as usual had a quick shower and douche as soon as I arrived and walked naked into their bedroom where they were waiting naked. They were already hard (they used viagra) and said they wanted me tied up. Soon I was laid face down on the.

She screamed lightly “Aaahhh”.I turned her over and twisted her nipples ignoring her begging to stop. I pinched the nipples and pulled them as far as I can. I rubbed her again and got her close to orgasm but. “Hmm. . .Uh-huh. . .There you go,” she said, winking as I slid my arms into it. “Now let’s get these strings tied.”The nurse stepped around to face my back and her warm soft hand brushed mine.
