I approached, curious to know who was there with my sweet wife…I sneaked from the door, hidden by the hallway darkness and I saw Ana on her knees. S...e was sucking a giant black monster cock of a perfect stranger black man…After some minutes I could not resist anymore and cleared my voice, telling:“Hi, honey…are you enjoying yourself??”Then Ana looked up and said the black man was Alfred. They had met in the pub and he shared her taxi to our home…It seemed that he was sharing a lot more than the. I knew the other two men had left her unsatisfied, just like her husband usually did. I’d given her the wildest night of her life, but she had warned me upfront that she was afraid of getting attached. More importantly, her husband was afraid she would get attached. It was a condition of their arrangement that she wasn’t to see the same guy more than a couple of times. I had every intention of making her change that arrangement. I couldn’t help but wonder if she had sensed my intention and. Anyway, one Tuesday this last summer, I’d just finished a run of night shifts and got home and decided to lie down by our pool to get a tan. It was a gorgeous day, the sun was shining bright and it was exceptionally warm. My backyard is well secluded and my neighbours were not home but at work. I was alone. I stripped off and put on a bikini, applied my tanning lotion and laid down in a deck chair by the pool and closed my eyes.I must have drifted asleep. The next thing I remembered was. Jen spent most of the day getting the house ready, preparing food and just doing the average hostess stuff. I noticed, however, that as the time got closer she prepared more like she was going on a date than having friends over for drinks.She wore a new shelf bra that I had not seen before. It was that kind that lifts and holds the breasts from underneath. The white lace fringe dancing below her nipples and areoles, allowing them to be easily seen, and accessed if necessary.Boy, did it work.
