[This is kind of a continuation of the other stories in the group. If you are keeping track of the time line, it happened after the two "senior year" stories, but way before the cruise. It doesn't matter, though, the story is not exactly complicated.
Any relationship to actual people or events is wishful thinking.]
*
We didn't really have an open marriage, but we weren't exactly angels either. I never brought girls home. Susan said it was OK if I had a fling when I was on the road, but I never brought anyone into the house.
For my part of the bargain, I never let her bring home guys either, but I knew that she was bisexual, and that she always had her eye on girls. The deal was always relatively simple: If she brought home a girl, it had to be a short term thing. Anything longer than a few days, and there was a risk of emotions, and the emotions might be trouble. Although she sometimes brought girls into the house, it was usually only if the girl had consented to let me watch (or join in). Otherwise, Susan would always just stay away for the weekend, or book a room at the local hotel.
Susan, mostly, kept her end of the bargain. When she met girls, it was usually complete strangers. There was no chance that the girl would know where I worked, and rarely even knew where Susan worked. She would always let me know before she had a "date", and I would usually make it a point to be away for the night. Some times I would catch a cheap flight down to Florida, and try to get lucky in Miami or Ft. Lauderdale, but airfare costs money, and I rarely hooked up with anyone as good looking as my wife..
The casual affairs was a pretty good relationship when we were younger. The sex was always fantastic, and we both gradually got over our fear that jealousy would break us up. We would always end up telling each other how our weekend went, and the stories always led to great sex.
When our son was born, though, we realized that everything would change. For one thing, we were both too tired to have flings, but mostly we stopped seeing other people because it just seemed like that phase of our live was ready to be finished. We still talked about our sexual experiences from time to time, and we even talked about what had changed. Neither of us ever prohibited the other person from sexual experimentation, it just gradually became a smaller part of our lives.
So it was a nice surprise when I came home from work one day and found Susan and our next door neighbor Rene sunbathing completely naked in the back yard. John Junior was a little over a year old, and he was happily splashing in the blow-up kiddie pool, also without a stitch of clothing on.
Rene was a lawyer who worked for a big insurance company, but had the looks of a supermodel. She was 25, the same age as Susan and I, but looked a bit younger because of her tight body and good complexion. Susan and I had gone out to dinner from time to time with Rene and her boyfriend Mark, (and each time, I had spent slightly too much time staring at her tits or her ass, and wondering what they looked like without the tight dresses.)
Although Mark was a pretty handsome guy, she was out of his league in almost every way. She was smarter and funnier than him, and I think she made more money too.
I no longer had to wonder. She was slightly taller than Susan, and slightly thinner too. Susan had a very light complexion, and kept her hair dyed dark, while Rene had a naturally darker complexion, and long brown hair with a touch of red. I spent a few minutes staring at her body through the window, and decided it was time to go get a better view. Our backyard had a privacy fence, but if the neighbors had decided to peek over the fence, nothing would have really stopped them.
I walked out still wearing my suit from work, and Johnny was the first to notice me. "Daddy!" he piped up, but me made no real move to leave his spot in the pool surrounded by his toys, only some of which were technically waterproof.
Susan and Rene both looked up at me, but both acted as if nude sunbathing was completely normal. "Hey honey." Susan was a little shorter than Rene, and a few pounds heavier. (Not that Susan was fat, but Rene was thin and lean, with the look of someone who does a lot of yoga or aerobics or something.) Susan and Rene both had nice firm C-cups, but the shape was very different. Susan's boobs were wide, and were more full on the bottom than the top, while Rene's were full on the top. I had always liked the way that Susan had relatively high nipples, but Rene's were even higher, to the point where they looked like there might have been a bit of surgery. Susan had a tiny trimmed patch of hair just above the pussy, while Rene was completely shaved.
Susan was curvy and soft, with a body that would do any new mom proud, but Rene was purely a fantasy girl. Her face made her look much younger, and her body put out a sexuality that was so strong I wanted to pull my pants off right there.
Rene's tan lines showed where her bikini usually sat, and she was so thin that I could tell her hip bones normally made a "bridge" out of her bikini. The light skin around her mound and breasts only emphasized how unusual it was for her to sunbathe nude. Her breasts sat up high, even though she was laying on her back, and when she turned to acknowledge me, she played one leg on top of the other as if to pose for me.
Susan had always been attractive to me, but I was having a hard time taking my eyes off Rene. "Hey Susan, Hey Rene. Not that I want to see him naked, but where's Mark?"
Rene laughed, in a way that made her even more adorable. "I broke up with him weeks ago. I thought you knew."
"Nope. We have been keeping to ourselves and just hanging out with John Junior. We wouldn't have noticed if you burned your house down."
Susan decided to chime in. "Rene just let me know that today in national nude day. We have only been celebrating for about an hour, but I am pretty sure you need to join us."
"Fair enough," I replied. "It looks like you guys need a refill, so I will join you in a few minutes."
I went inside and quickly changed into nothing at all. I wasn't sure what to do about my erection, so I decided to just let it fly. I wrapped myself in a towel while I got white wine for the girls and beer for me. By the time I got outside, my erection had relaxed to the point where it was pointing more-or-less downward, but still had a fairly good percentage of maximum size.
I decided this would be the best time to show it off, so when I went out, I gave the girls their drinks, and then walked to the last lounge chair, and took my towel off as casually as I could with both girls watching. When I spread the towel out, Susan said, "See, I told you," and both girls broke out in giggles.
Rene finally explained. "I told your wife that Mark was about seven inches, but that the biggest guy I have ever fucked was about eight. She told me that after seeing two naked girls, you would be about nine."
It was an exaggeration of course. Back in college I had actually measured my dick, and no matter where you placed the ruler, it always worked out to about eight inches. But it was nice of Susan to do marketing for me.
"Maybe she meant nine millimeters," I offered.
For the next hour or so, we sat and told crude jokes and put away a few more drinks. By the time the sun got a little lower, it looked like John Junior was ready for bed. I volunteered to do all the work tonight, hoping that "national nude day" would last into the evening.
I put some shorts on while I got Johnny bathed, fed, and ready for bed. He had only recently stopped breastfeeding, and he was already getting pretty good at sleeping through the night. I read him a couple of short bedtime stories, and he was completely asleep by 8 pm.
When I got downstairs, Susan and Rene were sitting on the couch, sharing a blanket, and both completely naked, waiting for the pizza in the oven to finish. First I delivered pizza to the girls on paper plates, and then brought yet another round of drinks.
When I made it to the couch with the drinks, Susan stopped me for a second, and pulled my shorts down to the ground before letting me sit. My dick was already at full attention, and Susan motioned for me to sit on her end of the couch, so that she was between me and Rene.
When I sat down, Susan placed her pizza and drink on the end table, and promptly leaned over and took my dick in her mouth. It felt amazing, and it was sexy as hell to have Rene watch as my wife lowered her head down onto my dick over and over. From where I sat, I couldn't reach the blinds, and I realized that if the neighbors decided to look in, they would have and excellent view of the three of us on the couch, but I decided not to say anything, and just let Susan put on a show.
I was horny already from the nude sunbathing, and I knew Susan was as well. She must have primed Rene at some point, because Rene didn't seem bothered at all by Susan suddenly giving me a blowjob.
