Impossible for me to think of a "best", but for a while, a few years actually -we got into a groove that seems like one long happy orgy to me now that I looking back on it. My favorite time.
We use to roller blade along alki beach, (we lived only a couple of blocks off that beach) run, fly big kites, play v-ball etc, so on the weekends anywhere from two to eight couples we played with all the time would congregate at the house, and basically share all that with us. Sometimes new friends would wander in too, usually there was quite a bit going on.
It was a very organic, relaxed thing, and especially in the summer time when we had weekend long 'partys' (nothing planned , all very informal) everyone having sex with everyone else in between all the fun on the beach.
We would go out to this funky yummy little place for breakfast all together, go back home for a mid morning romp or to complete facinations unrealized from the night before. Then we might go blading or something fun like that, then go to lunch or all help make it naked, then more sex, maybe a nap -and between having sex -having fun out and about and blading or other fun was like long never ending foreplay with each other. Sensuous, hedonistic, horny and hot times. Relaxed, sultry sexy times.
The only rules were have fun, play nice and share. Toward evening we might have a BBQ in the back yard or a tiki party with goofy Don Ho music playing. Once in a while we would all rent a limo (or two- cost no more than a cab) in the evening just to go a few miles to have dinner at a cool little seafood place, then maybe limo off to the sleepy little local tavern to have a couple of beers, dance to the jukebox and shoot a little pool.
Then back to the house all horny again and ready to suck and fuck the night away in what amounted to a big slithering naked pile. People might drift in and out during the day and evening as the weekend progressed, and who knows who's arms you would end up falling asleep in -exhausted, bare and happy. The house was two story, but smallish (cozy!!!..lol!) and after any morning waking ya ya's, we would shower four or more at a time (only one bathroom per floor). Then the cycle of the day would begin again, and eventually we would all head out to breakfast and another perfect day.
I think how natural and easy and how things just flowed is what makes that such a fond memory for me. Also, it is such fun to do everything in a group like that, and to feel life be that integrated.
