He had a marvelous collection and I think he'd selected them real carefully for that night. I mean, he started out with some soft, dreamy ones that put all of us in a sentimental mood. And when the two couples of us were all snug and hanging onto each other at opposite ends of the couch the music gradually began to have a strong, urgent beat under the melody. It was still soft and sentimental, but there was an undercurrent of eagerness that did things to me.
I felt all warm and cuddly and awfully sensitive to Eric's touch. I kept pushing tighter against him and squirming and making little noises in my throat. And once in awhile I heard Nancy making the same kind of noises to Mark.
"Hey, those kids are getting carried away!" Eric whispered into my ear.
When I stopped shivering from the thrill his warm breath in my ear sent over me, I nodded and gulped. "Don't worry about them. They've been experimenting. Getting pretty good for kids."
He chuckled. "Sonofabitch. How do you think they'd react to a night of grown-up games?"
I couldn't help laughing aloud. "They'd love it, I'll bet!"
He grinned and got up. "You guys!" He barked at Mark and Nancy. "Either one of you ever see the rest of my apartment?"
They both shook their heads.
"Not since you moved in," murmured Nancy. "Ma said she'd skin me if she caught me going through it."
"Well, how about a guided, chaperoned tour?" He turned up the volume on the stereo.
The music was still gradually changing character. The melodies were wilder and more urgent now and the beat had become a fierce throb. We followed him into his bedroom. Even I hadn't been in there with him! God, what a bed! It was a king-size water bed! And I know my eyes were as wide as either of the kids'.
We had to try it out. I'd never been on a water bed, and the way the surface yielded and surged under me was sexy, itself. When Nancy joined me and started jerking around, it was weird! I kept gasping and shivering with unexpected sensations. And Mark dropped down between us and made it even worse.
Eric laughed. "You think that's good, you ought to feel what it does to you when you're naked!"
Just like that! And just like that, we started stripping off our clothes! It wasn't two minutes before the four of us were mother-naked in a pile on the bed. And Eric suggested a game.
"Look. This thing gives wherever you push it. Try crawling on your hands and knees."
It was hard to keep our balance, let alone keep moving. We crawled over each other and fell under each other and grabbed at things to steady ourselves. We could hardly hear the music over the squeals and shouts of laughter. And we weren't playing a simple game of crawling around very long, either. It didn't take very many times of having one of my boobies grabbed or someone clutching at my pussy to channel my attention to getting laid.
I got hold of a cock and had it halfway into my mouth before I realized it was too small for Eric's. I decided it didn't matter too much; there was a whole night ahead of me. So I gulped it in, the foreskin slipping back easily this time, and sucked tenderly while Mark was fumbling at Nancy with his hands.
It was kind of kooky that way. Eric was pawing at me and had my legs all spread apart and his face buried in my pussy. Mark was watching the beautiful man out of the corner of his eye and imitating every move, doing the same thing to Nancy that Eric did to me. And she kept her hips jerking while my little brother mouthed the wet, eager, soft membranes of her pussy. She struggled valiantly with Eric's huge cock, too, gulping at it and finally managing to get the gorgeous, shiny-velvet head into her mouth.
The two men were on their backs while Nancy and I crouched over them crosswise. I think it would have made a strange scene if there had been anyone to stand back and take it in. I mean, Eric was such a big, muscular, beautiful mountain of a man and Mark was still so slender and young and angular. And I'd filled out to become a curvaceous, full-fleshed woman, while Nancy was still the lean child with only the beginnings of roundness.
But there wasn't a whole lot of difference in our eagerness. She worked just as hard and made just as many wet, slurping noises over Eric's cock as I did over Mark's. And her hips were churning so I'm not at all sure I was putting out as much energy as she was.
I know she reached the limit of her endurance a lot faster than I did.
"Oh, my!" She cried out, releasing the great, slobbery cockhead. "Oh, my goodness! Somebody fuck me! Quick! I can't wait!"
Mark grabbed her waist and twisted her around so she straddled his hips. "How about riding mine?" he asked.
She looked dubious, but there was a gleam of excitement in her eyes. "We… we haven't fucked with me on top before," she reminded him doubtfully. "Is it all right?"
Eric's laugh boomed. "You scared of squashing him?"
"N-no, but…"
"Go ahead, honey," I told her softly. "Never mind Eric. You'll get a kind of sensation you've never had before."
"Oooh, you make it sound exciting!"
"It is."
She shifted her knees, fitting them into the hollows at the sides of Mark's waist, and reached under herself to position his cock so it rested against the wet, pulsing rim of her cunt-mouth. She settled back, slowly engulfing the young, bulbous cockhead.
"Mmmm… Ahhhhh… Ooohhh! Oooh, Lee! It feels sooooo good!"
Her hips jerked, stroking her on the thick, stiff shaft and bumping her glossy black pubic hair onto Mark's. Eric straddled Mark's legs and bent over the girl, his hands caressing her waist and buttocks until she quivered wildly.
"Omigosh!" she exclaimed. "Oh, golly, it feels funny to have two of you feeling around when one of you is fucking me!"
Eric inched closer to her and pushed his cock down with one hand so the enormous, bulging head nudged the crack of her ass.
"Eric…! Oh, Eric…! Omigod, could you…? Marky, darling…!Would you be mad if Eric…"
"A sandwich!" Mark yelled enthusiastically. Then he added in a tone of resignation, "He'd never be able to get that giant of his into you back there."
"He can try! Try, Eric! Oooh, try!"
Eric winked at me and gestured. I went to his side on my knees and fighting the damn bed's unpredictability – and he kissed me tenderly. Then I leaned against his shoulder while he lubricated the girl's ass with saliva and spread her eager young buttocks. Even my memory of the way his cock had buried itself in that tiny asshole couldn't rid me of the conviction she was too small for him. But as he pushed and her soft flesh heaped up around the wedging, monstrous knob at the end of that rigid, massive shaft, I realized the puckered little anus was expanding and gulping.
Little by little, the huge, blunt-tipped cockhead disappeared into her.
Her eyes bulged and she panted hoarsely. "Marky…! Oh, God, Marky…! Hold me!Hold me tight!"
Mark clutched her to him, his lips tenderly brushing her face while she strained and gasped. His concern was obvious and he winced every time she did. Eric's cock slid swiftly inward, burying itself in her ass, and she was pinned between the two men. An expression of elation made her face glow.
"Omigosh, Marky! I'm so full I'll pop!" she exclaimed in a whisper. She extended her legs outside his and lay flat on him.
Eric supported his weight on elbows and knees and surged forward and backward, stroking his enormous pecker in the girl's ass. The movements shoved her back and forth on Mark and a strange, trance-like look came into my little brother's eyes.
"Jeez! I can feel his cock, too, Nancy! Just as if he had it right in the same place as me!"
