About a month ago, I received a call from Tom and Tammy, a 40-something couple I met last summer at a nudist resort near my home. We'd hit it off, and after spending an entire day together, we'd exchanged phone numbers. After three months, I frankly never expected to hear from them, but one October afternoon, I found myself talking to Tom and toward the end of our conversation he invited me to come to his home in posh Fox Point, hang out nude with him and his wife, and maybe have a little naughty fun. I told him I was in, and a date was set for our tryst; Saturday, October 13th. I arrived on the appointed Saturday at precisely 1pm, and Tom met me at the door wearing only a spa robe. He ushered me in and introduced me to his wife, Tammy, who was seated on the couch similarly attired. As Tom fetched me a Diet Coke form the kitchen I noticed that a porn movie was playing on their big screen TV., and as I nursed my drink, talk turned to sex. Tom admitted that both of them had often fantasized about being watched (or photographed) by a third guy during love-making. He added there was no guarantee I'd be invited to join in, but added that they were open to the possibility -- if the mood was exactly right. Before I'd even finished my drink, Tom suggested we all get naked and reconvene upstairs. Clad only in robes, my hosts were standing nude before me in about two seconds. As I wriggled out of my jeans and underwear, I noticed that Tom was already sporting a nice semi, which Tammy was playfully squeezing and tugging. They both complemented me on my shaved body and emphasized that they had no previous experience with threesome play. "So let's go upstairs and get some experience," said Tom. I followed obediently as they bounded up the stairs and down the hallway to their master-bedroom. My hosts peeled back the covers and climbed into their huge king-sized , and as they situated themselves amonng the half dozen or more frilly pillows at the head of the bed, they directed me to make myself comfortable in a read leather wing chair positioned only a few feet away. I was told that I was free to pleasure myself as I watched them so long as I didn't get anything on the chair. A small pink Olympus digital camera lay on the nightstand, but no mention was made of taking photos. My hosts went right to work, engaging without shame or inhibition in full-out foreplay, which quicly progressed to oral sex; first him on her, then she on him. As they wriggled and moaned,not three feet from my vantage point, my cock went rigid, and I began working my hand up and down its length. I couldn't help noticing that my hosts would occasionally glance over to see what I was doing. Soon Tom was preparing to mount his missus in the missionary position. "Can you take a pic of this?" he asked. "Just press the power button and shoot." The camera sprang to life in my hands, and as Tom penetrated Tammy in three of four thrusts, I squeezed off a burst of several photos. Before long, Tammy was on top, kneading her pert breasts and pinching her erect nipples while gleefully impaling herself on Tom's glistening organ. Again, Tom gasped, "Get pictures of this! Get really close this time!" I did as he requested, firing off another burst os everal explicit close-ups from point blank range. Finally, I found myself snapping more pics as Tom positioned his lady on her knees and entered her from behind. As he sawed in and out of her, I could tell from the increased tempo of his thrusts and his deep, raspy moans, that Tom was close to cumming. Frankly so was I! "Here I come," he gasped. "I'm cumming. I'm cumming." I snapped a few more pictures as they collapsed, still coupled, into a dishheveled heap. "I really enjoyed that, " he said. "Now let me show you something else I enjoy," he said to his freshely-fucked wife. With that, Tom got up, and as Tammy watched, he knelt before me, and began stroking my cock, as only another guy knows how to do. "You'd better stop," I said shyly, "or I'm going to cum too." Although my eyes were closed, a familiar feeling of warm wetness told me that Tom had taken my cock into his mouth, and was playing his tongue skillfully on its sensitive underside. I slid forward a bit to accommodate him and in less than a minute I felt my own orgasm washing over me. Tom pulled away, but continued to stroke me as six or seven more jets of semen splashed onto my belly. "How'd you like that?" Tom said proudly. "Bet you didn't think I had it in me, huh?" His wife looked on with a shocked expression. I could tell Tammy wasn't expecting her hubby to bring me off orally, or in any other way, and that she wasn't thrilled with Tom's spontaneous act. "That wasn't what we planned,” she protested. "If you want to do that bi stuff, you can count me out." Tom produced a warm washcloth for me to clean up with, then suggested I'd better go so he could straighten things out with his disapproving missus. Still naked, Tom led me down to the family room, where I dressed hurriedly. "It'll be cool," he assured me. “It was fun. I just took her by surprise, that’s all.” "We'll be in touch," he promised as I headed out the door, but I haven't heard from either of them since.
