My name is Mark, and I'm a 42-year-old IT Manager. I'm also husband to Jill, my gorgeous 36-year-old wife, and step father to her 18-year-old daughter, Samantha, or Sam. We met while I was in grad school and Jill was finishing undergrad. She'd married her first husband young and had adopted his daughter from a previous relationship when they wed. Sam's birth Mom signed Sam over to her Dad and disappeared, and when he died in a tragic work accident Jill started to raise her alone. With a generous settlement from the company she was able to go back to school and start a new life, which is where I met her and fell in love immediately.
She never wore makeup, never needed it with her beautiful complexion, and kept her auburn hair just below shoulder-length. At 5'4 and 115 pounds, with perfect 34D breasts, beautiful green eyes, and a stunning smile she was my dream girl. While they weren't genetically related, Sam looked so much like her stepmother no one knew they weren't blood relatives, though most mistook them for sisters by the way they acted and their age difference. Sam was a good kid and grew into a good young adult, so not much was needed in the way of parenting now. She was a little taller, with the same auburn hair color, and while I wasn't "checking her out" per se, I had noticed that she was a very shapely young woman, just as busty as her stepmother, and just as beautiful.
Jill took up running in her 30s to stay trim and fit while I focused on getting to the gym several days a week to keep in shape. Our sex life, in my opinion, was above average, and while she often needed me to use my fingers or her vibrator to get her off she seemed satisfied with my 7 inch cock. She never seemed interested in giving or receiving oral, but we had sex 2-3 nights per week on average. And while I'd have liked her to be more adventuresome I felt lucky to be with her. She wasn't a prude, and one drunken evening early in our marriage we'd discussed fantasies. She was shocked and seemed a little turned on by my admission that I thought it would be hot to see her with another man, while she shocked me (and turned me on) when she revealed her threesome fantasy. But we as soon as we sobered up those fantasies weren't discussed again.
Jill had met another couple in her running group, Matteo and Alexis. I had met them a few time when they stopped by to pickup and drop off Jill for a few weekend runs. Both were attractive fit runners, Matteo being a little shorter and thinner than my 6'1 and 195 and Alexis being slightly taller and thinner than Jill. They were both in their late 20's had yet to start a family. One weekend Sam went to stay with my parents nearby, as my mother loved to shop and go to shows with her, and that's when things changed for us forever.
Matteo and Alexis had a house in the country on some acreage for weekend getaways, including a small vineyard, pool, and hot tub. They invited Jill and I out during the Sam's sleepover and Jill jumped at the opportunity. I'd been under a lot of stress at work on a project that I'd finally finished and was looking forward to a relaxing weekend, and while it sounded like a great opportunity the stress of social interaction was daunting. But she won me over with her beautiful smile and a bit of flirting.
"C'mon hon, it'll be great,",she said. "A pool and jacuzzi, and I've heard Matteo can really cook. I'll wear the little bikini I got for the cruise last year."
"The dark green one that's barely there?" I asked. "Sounds awesome but risky."
"Don't worry, I'll get waxed and make it worth your while," she said.
And that was all it took.
It was summer, so we packed our swimsuits, a few changes of warm weather clothes, some running clothes and toiletries, then left work a little early on Friday to get a start in the weekend. After dropping Sam with my folks we made the 45 minute drive to their place. It was a short drive but big change, as we climbed a few thousand feet on winding roads on the way.
The house was amazing, like a small Italian villa tucked away in the mountains. They greeted us warmly with champagne, showed us to our room for the weekend, and ushered to the dining room where a rustic but fantastic meal was waiting.
The conversation and wine flowed easily at dinner. We chatted about work, vacations, and fitness. It was relaxing and I was glad we came. I helped Alexis clean up after the meal while Jill and Matteo chatted on the sofa. Afterward Matteo offered a toast and a suggestion.
"To new friends and new adventures. And, to the hot tub," he said as he raised his glass.
We all agreed and headed off to change. While the night air was a little crisp the water was warm. Both Jill and Alexis looked stunning in their suits, and I stole a quick glance at their hardened nipples and flat abs as they headed across the pool deck. I hadn't noticed before but Alexis had quite the bust for someone so thin, but chalked it up to usually seeing her in a running bra. I was relaxed, feeling no pain and enjoying the view.
The stress of the week and the alcohol, combined with the warm water, took its toll on me and I soon found myself yearning for bed. I excused myself to retire, to my wife's dismay, and promised to be a more energetic guest the next day. Matteo and Alexis were quite understanding and wished me a good night, as did Jill as she decided to stay a little longer.
I heard Jill come in a little after midnight and turn in with a frustrated sigh, muttering something about my being a party pooper. I was a little annoyed at her lack of empathy and feigned sleep, hoping that it would blow over by morning.
Around 1:00 that night I got up to pee and noticed that our bathroom window looked out into the hot tub area. Peeking through the curtains I saw Matteo and Alexis passionately making love. It was a huge turn on, and I soon found myself masturbating at the sight. It didn't take me long to finish, as I'd been preoccupied with work and had been too stressed for sex for over a week. Unfortunately for me my wife needed to pee too, and turned the light on as she entered. When I spun in surprise she saw me cleaning my cock head with the tissue I'd caught my load in. She winced in disgust, shut the light off, and went back to bed. I finished cleaning up and flushed, heading back to bed. She brushed past me angrily on her way back in.
"I can't believe you jacked off instead of waking me up," she spat.
I stopped her and said, "Look, Matteo and Alexis are still in the pool area and fucking, so leave the light off."
I thought that'd be helpful, but I was wrong
"Oh my god, I can't believe you were jerking off while watching my friends!" she said.
She went to the bathroom and left the light off, staying so long that I fell asleep again. I didn't see her again until the morning.
While I wasn't sure if Matteo and Alexis saw me, Jill's attitude toward me at breakfast made it clear to all that something had happened. Then Matteo started hinting that they saw me.
"What's up you two?" Matteo asked with a smile,"Did you guys see a ghost last night or something?"
"Yes, we stayed up a little late last night and felt like we were being watched from the darkness," Alexis chimed in. "Did you all feel the same?"
My wife blushed, then responded.
"Look, I'm sorry but we both saw you through the bathroom window last night. It was wrong to watch, but I couldn't help it. And to be fair," she said looking at me,"Mark noticed first. We're really sorry. We can pack after breakfast and head home."
I was stunned at her admission. Had she masturbated to them as well?
"Nonsense," Matteo said smiling,"it's as much our fault as yours. Besides, we enjoy being watched. It's one of our kinks. We didn't mean for it to happen, and we apologize. But I hope you enjoyed the show."
"Mark certainly did," my wife smirked.
"Well you stayed in the bathroom so long I fell asleep," I responded.
