In no time at all Jon's pants and underwear were on the floor. Karyn gave his cock an erotic squeeze, then lifted his shirt over his head. As she did this, Jon could feel his erect cock slide against her thigh, and her pert nipples slide across his chest.
"You don't seem very interested today. What's the matter? Do you have a headache or something?" Karyn asked once Jon, like her, was completely naked. Then, perhaps to raise Jon's interest, she resumed gently squeezing his cock.
"No, I just thought I'd, uh, follow your lead, uh, today," Jon replied. He kept wondering, though, why Karyn was there at all. His wish had been for incest to be normal, and that explained why he might have sex with his mother, his sister, or even his brother or dad. But that didn't explain the group sex arrangement, nor Karyn being so promiscuous with his whole family.
"Well, come on before I explode," Karyn urged him, and then she fell back on the huge circular bed, pulling Jon with her. Then she pulled the covers over both of them and they began rubbing, touching, and kissing each other in every spot they could reach.
Then, out of nowhere, Jon felt more hands on his body. At first he thought it was Zoe, but then he heard a moan in his mother's voice, and he felt her pulling one of his hands onto her butt. Jon recoiled and wanted to pull away, but that would have meant pulling away from Karyn as well. Then someone else kissed him on the back of his neck, and he felt more hands on his hips, thighs, and butt.
Jon groped around the tangle of bodies, hoping to touch something that might be Karyn's. That was the important part, he decided: to stay primarily in contact with Karyn. After a while, though, he could only stay in touch with Karyn's hips, thighs, butt, and pussy. Her other end was doing something with Jon couldn't tell."
Someone -- probably his mother, Jon decided -- started crawling head first along Jon's body and down the sheets. She stopped when her lips were inches away from Jon's cock, then urged him, "Touch me, Jon. Touch me like you do so well."
Thinking diligently about his partial hold on Karyn, Jon dutifully reached over and touched his mother between the legs. "Oh yes! Deeper, Jon; deeper and then higher," his mother moaned. "Lube me up the way you always do!"
Someone else, meanwhile, started to climb over Jon's head and rest his head against his mother's neck. It was Mikey! "Oh mom, I'm so close," Mikey whispered, then he whispered it again.
"Jon, help your brother, would you? Don't stop on me, though," his mother gasped between moans. Jon couldn't believe this was happening but, keeping in touch with Karyn, he took Mikey's cock into his mouth. Mikey relaxed against Jon's face, then their mom relaxed against his cock, then Karyn shifted position. Jon wasn't sure whether Karyn was servicing Zoe or his dad, nor did he wish to know.
For what seemed like hours, the rolling, kissing, touching, sucking, penetrating, bumping, and grinding continued. Jon came with his mother, then with Karyn, then with Zoe or Mikey (he wasn't sure which). Karyn sucked off Jon, Mikey, and Jon's dad, and she also played around with Zoe and Jon's mother. Jon lost track of all the other combinations and eventually fell back exhausted, coated and reeking with cum, pussy juice, and sweat.
"Mmmm, that was good," Jon's dad remarked when he and everyone else had finished.
"Yes, you're good children, all three of you," Jon's mom told her children. "And Karyn, I'm so glad you're a close friend of the family, now."
"Me too," Karyn replied. "I'm so looking forward to all of you visiting at our house Friday night.
"Well, I'm going to shower and clean up," Jon's dad announced, then he, Jon's mom, Karyn, and Mikey all jumped up and ran giggling to the showers.
"It looks like we got crowded out again," remarked Zoe. "C'mon, let's go downstairs and wash each other in the hall bathroom." Then she took Jon's hand and the two of them scampered naked and cum-soaked down the stairway.
"Oh, I didn't hear you come in!" Zoe exclaimed when she got halfway down the stairs.
