After our last round of playtime, we were all pretty much fucked out. So we had a swim in the pool, followed by a second lunch, which we ate at the poolside. We talked about the concert that Jack, Bob, and Rosie had gone to, and what they were taking in school, and so on. I had a good chance to look at the junk on the twins, and noticed how their balls hung lower than the ones on me and my Dad, and how their dicks didn't get any shorter when they were soft, like mine and Dad's did. Somehow, the subject of sex didn't come up again, but the women disappeared into the kitchen for a while before reappearing. Rosie came back out first.
"What were you talking about in there?" I asked her.
She smiled and said, "You'll find out!"
Then Mom and Lori came back out. Mom got our attention and started to speak.
"Once in a while, when we have enough people, it's a family custom to have an orgy. That's right, everybody fucking everybody! Well, we have eight people here. I think that's enough."
Lori explained the rules. "First, this particular game we'll be playing is all about cocks, cunts, and cum. That's the focus, and not the closeness you get with your partner when you screw. The rest of our family fucking is about that. But here, the whole idea is that when you're getting a succession of cocks in a row, or cunts in a row, it's the variation that excites you. Linda, you have something to add?"
"Yes, I do," Mom replied. "This comment is for the young ones here. I know Jeremy has seen Gary and Dee fuck. And Gary and Diane and I have shared a bed last night. And maybe Lori has had her kids in bed, right? But those were all for extended sessions of lovemaking. That's not what we're going to be doing here."
She paused to take a sip of water, and then resumed. "You've got to understand that this is different from the family lovemaking we do. This is strictly an exercise in pleasuring cocks and cunts. Maybe tomorrow, or sometime later, we'll do another kind of orgy, a more free-form one where we take turns pleasuring each other without a timer around. But this is more of a game ... a relay race, not a school dance. Understand?"
I nodded, and the girls and the twins did, too.
Mom finished off her drink and spoke again. "We've all had at least a couple of fucks by now, so none of the guys should be on a hair trigger, and all of the gals should be most of the way to a good buzz. Let's all go to my bedroom, and we'll start. First, though, we've got to get all the guys hard again!"
Rosie grinned at me. The boys looked at each other, and then at her, and then at Diane. It was obvious that they were as clueless about what was going to happen as I was. Dad brought out a box of about a dozen cock rings, all in different sizes. He slipped one onto each of our dicks before they were fully hard. "Better a little too tight than a little too loose," he instructed as he slipped one onto his own cock. "And those are yours to keep! A souvenir of the boys' first orgy! Now girls, get us guys hard, so we can test the fit!"
"What do us girls get?" Rosie asked.
"Nipple jewelry!" Mom said, as she held up a box of her own. She passed them out, and each woman got a pair of nipple rings, designed so that they could be adjusted to any diameter the girls wanted. There was a lot of giggling as the ladies slipped them on their long nipples and clamped them down. "Not too tight at first," Lori instructed. "The more you get turned on, the tighter they can get, but be careful not to constrict the blood circulation." Diane and Rosie looked at each other's bejeweled breasts and giggled.
In the bedroom, Mom explained the ground rules. "First, it's going to be the ladies' turn. Lori's going to get on the edge of the bed and have each of you guys fuck her in turn. You each have five minutes, or until you feel you have to cum. That's when you're going to turn it over to the next guy. If you cum, you're obviously out of the game. We're going in order of age... first Gary, then... I forget. Which of you two boys is older?"
"Bob is," said Jack. "By about ten minutes!"
"You go ahead, bro," said Bob. "It's time you get to pull rank on me!"
Lori spoke up. "And, Linda, you go ahead of me. You're the hostess!"
"If you want," Mom replied. "So the four guys will fuck me first, then they'll fuck Lori, then Diane, and then Rosie."
We all nodded.
"Let's get started, then." Mom resumed. "First Gary, then Jack, and then Bob, and then Jeremy. OK, let's start!" And she lay down on the bed so that her crotch was positioned right at the edge and spread her legs as she started the timer.
