Stella Maris started to spend most nights at me. For convenience, as I lived in a dorm in old town, and for some super sex together at a regular basis...Stella Maris I met at her first day at Amsterdam University. As a senior student I often led groups of freshmen during their first week in town, in a light programme of getting to know the University and cultural events in the city. An ideal deal for me: usually broke after a Summer holiday, I got food for free for five days, lots of. But as my cock begins subtly twitching and my hips began a slow undulation, I feel her grip shift. First, one hand wraps around my cock, then both. With that, she begins pumping up and down in an unmistakable milking motion. In my brief sexual career, I've been on the receiving end of my share of hand jobs. But nothing prepared me for this. There is something about kneeling in what is, in effect, a "missionary" position that amplifies every sensation. That coupled with Su-Yun's sublime control. "You wanna get naked too, Dad?" Mark said. I knew that Mark and his dad sometimes soaked nude together, and the thought of him being naked in the tub with us made my cock stand up. "Oh, I don't know if that would be appropriate," he said, looking over at me. "I don't mind," I said. I was feeling horny, and bold. "Come on, Mr. Jones, if we can do it, you can, too!"He shifted a little and said, "Oh, I don't know..."I stood up in the tub and shifted over to his side and made eye contact with him. At that time the US Air Force had a station known as Wheelus Air Base just outside of Tripoli. As a young airman I was sent there on a two year tour of duty with the 633d AC&W (Aircraft Control and Warning) squadron. We jokingly called it “the sex thirsty third”. On a weekend shortly after I arrived there in 1956 the Suez Canal Crisis erupted over a weekend when most of our personnel were off duty. I was a cryptographer, and our squadron message center began receiving high priority encrypted.
