This story is the sequel to the narrative of my wife Jill's trip to Paris with my sister Kim.
Sultry August moved to a close and we successfully moved my stepdaughter Mia into her Morningside Heights apartment for her first year of grad school. During the early weeks of September we didn't see a lot of my sister Kim, though I know that she and my wife Jill were spending time together. I knew Jill was shuttling between our bedroom and the one at the other end of the long upstairs hall where Kim stayed when visiting (it was fast becoming her room). It wasn't clear if Mia was in on this little morsel about her mother, but given that she was in on the deeper family secret this one seemed rather pedestrian by comparison.
On the infrequent occasions when Jill had other lovers (male or female), the liaisons usually took place on neutral ground, so this arrangement took some getting used to on my part. She made a pretense of coming back to our bed before morning, not that either of us had any illusions about where she had been during the night. And I wasn't about to admit that their trysts stirred my prurient interest.
As autumn arrived, Kim started spending more weekends at our house. She and Jill would often play tennis at our club and the three of us would enjoy a nice Saturday dinner together. Kim was able to show off her considerable culinary talents in what she called her way of working off the rent.
Unknown to me at the time was Kim's outlook was changing. With Jill's help, she was coming out of her shell and beginning to enjoy life with considerable zest. She seemed more relaxed, more with it, and more open. The hangups she'd developed during so many years of marriage to a repressed twerp were melting away.
One late Saturday night I stirred to find myself alone in bed. I knew Jill must be at the other end of the house where Kim's room was situated. I shouldn't have, but couldn't contain my lecherous curiosity. I mean who among us can resist the temptation of seeing two sexy women making love? Well, maybe a lot of people, but I'm not one of them.
I rose and stole silently down the long hallway, past the big staircase and the small table next to the railing which used to hold a telephone back when there were such things at various places in the house. I passed what used to be the kids' rooms on either side of the corridor, moving slowly for fear of bumping into a wall and revealing my presence. There was just enough ambient light to avoid trouble.
When I arrived at the end of the hall I noticed that Kim's door was cracked slightly. Had Jill left it ajar on purpose, or had she been careless in her haste to get into Kim's bed? Either way, it was easier for me. The dresser positioned just next to the doorway mostly blocked me but I could spy the bed on the far side of the room by the east window.
Jackpot!
Sprawled on the bed was my naked wife and my naked sister. Jill lay on her back, her long firm legs spread wide while Kim, lay on her belly, her face buried in Jill's pussy. Kim's arms were wrapped around Jill's thighs, holding her firmly in place while her talented tongue made Jill squirm in delight. Soft moans escaped Jill's lips as they made love; her head jerking one way and then the other in a way I knew well. I knew Jill's orgasm had arrived because her entire body vibrates and twitches and her right leg jerks uncontrollably.
Kim's body looked magnificent as her lower legs pointed toward the ceiling, almost casually crossed at the ankles as though she were reading a book on a deck chair by the pool. If I didn't retreat that instant the painful erection in my pajama pants was going to explode and I wasn't at all sure I could maintain absolute silence when it happened.
As quietly as I could, I retreated whence I came and was soon back in my own bed, unable to restrain myself any longer. The sight of those two sexy women making sublime love on the bed was more than I could take and with visions of a taboo threesome dancing in my head, I quickly relieved my tension.
Incredibly, I awoke the next morning with an impressive erection. I reached over to the other side of the bed to find Jill gone again, though I had a shadowy recollection she had returned at some point during the night. I heard the shower going in our bathroom so she must be close by. The door was half open so I went in to brush my teeth and let Jill know I was awake. I admired her shadowy form through the frosted glass of the shower doors.
Over the sound of the water and the overhead exhaust fan, Jill called to me in her smoky, come-hither voice, "Do you want to wash my back?" It was our code for come on in and see what naughty fun we can have in the shower.
I dropped my shorts on the floor and climbed in. Jill handed me her sudsy luffa and I got behind her, washing first her back and then her wonderful ass. Then I paid particular attention to the front of her, reaching around to massage the soap into her breasts. With the other hand I pushed her button and she began to tremble, grabbing hold of towel rack on the side wall.
At that moment I remembered the story Jill heard from Kim, about my sister watching me in the shower with a girlfriend those many years ago and I began to fantasize that Kim was now just outside the bathroom, wearing nothing but a t-shirt, watching Jill and me make love. The delicious thought caused an amazing resurrection of my cock.
Jill reached back to stroke me and moaned, "Give it to me."
I positioned myself directly behind her and she instinctively arched her back, raising her buttocks to give me easier access to that most special place between her legs. As much as I enjoyed my summertime romps with Lena, nothing could compare to being inside my sexy wife. Despite the fact that I had just gotten off a scant few hours before, I was still raring to go for Jill. It was almost as if she had discovered a secret fountain of youth that gave me powers I haven't had in fifteen years.
While I began to pump in and out of Jill, I stole a glance over my shoulder to see if I could spy Kim spying on us. It was a ridiculous notion, I know, but it heightened my arousal considerably. Through the distortions of the glass, I convinced myself that there was someone there, mostly obscured by the door jamb, but nevertheless sneaking peaks.
Jill dropped her head, resting it against the tiled wall as she came. That was all it took as I let out a long, lewd groan and emptied myself into her. As I did so my only conscious thought was, if only Kim could see us now!
We were drying off and otherwise preparing to get on with our day when Jill asked, "Did you enjoy the show last night?"
I'm sure my face flushed, certain as I was that my nocturnal reconnaissance mission had been undetected by the subjects. "How did you know?"
"I didn't," she replied saucily. "I just knew you would try at some point and I took a chance. Don't worry, I don't mind." I smiled in embarrassed relief. Jill sure is a good sport about my predilections. "You probably wished you could have joined in."
"Who wouldn't?" I asked.
"True," she replied. "Do you ever fantasize about being with Kim?"
Never one to keep secrets from my highly-sexed wife, I said, "Sometimes."
"That would be interesting," she said with a cryptic smile. "You should think about doing it."
"Oh, I'm definitely thinking about it!"
In October, with the fall colors appearing on the big oaks in our yard, Jill planned to go to New York for a week while Mia was on fall break. Though I miss my wife when she's gone, it would be a chance to get some work done and do some chores around the house. Jill always appreciates how tidy the place is when she gets back.
I dropped Jill at the train station and was home with most of the morning still in front of me. It seemed like a good day to straighten my study and then do some work in the yard when it warmed up after lunch. My evening plans included some Chinese take-out and a movie.
