I got my mouth into it, and she was wet as surf. Her own cum and David's were thick and delicious, and my tongue shot inside her again and again, licking and slurping and vacuuming her dry. David's hand was on my ass, petting me, tickling my anus with a clever finger, slipping in toward my cunt from the rear, and I passed on the frisky sensation to Dierdre. I only stopped when my jaws and tongue were numb with the exertion and my body yearned for a little rest. You can carry even a good thing too far, I guess. Another lesson I'd learned today. But I only craved a little rest, to be sure. I'd be ready to go again, and soon. I knew it as I settled beside the Banks siblings and soaked up the warmth of the sun and their glowing bodies.
The sun had gone noticeably lower to the west. Dierdre was sitting on one of the patio chairs, a leg slinked long and sexily across the tiles, the other leg wrapped around David's neck as he feasted in her pussy. I was in there too, playing with his dick, trying to coax it hard again. There was a definite response, but it was slow and sluggish. Of course, I was pretty slow and sluggish, too, what with the myriad of climaxes I'd gone through this afternoon.
Not to mention the happy vibrations I got from David and Dierdre. I'd known them such a short time, but it was like I'd known them always. A brother and a sister, they were in some ways, and so much, much more. I leaned my cheek against his shoulder, tickled Dierdre's leg with my hair, and kept on fondling his tool.
"Hey!" I said suddenly, letting him go. I sat up. "Did you hear that?"
"Mmmmm?" Dierdre murmured. She cupped her breasts, squeezed them till the nipples pointed out all stiff and luscious.
"It was a car," I said. "Stopping out front, it sounded like." David kept licking her snatch. "Well, for Chrissakes," I went on, grabbing my jumper. Where in the hell was my blouse? My underwear? "It could be your mom and daddy, you dumb assholes!"
There was a sound at the house the sound of a door sliding open. I clutched the jumper to my breast and turned, breath catching in my throat. A man and a woman were standing in the doorway, watching the three of us. "Oh, my God," I said, turning as pale as a lily.
I felt about two feet tall, and I tried to shrink behind the jumper I was using to cover my nakedness. This was the most horrible thing I could imagine being caught at, and I must have turned green when the man said, "What's going on out here, may I ask?"
I didn't look at them as they came out of the house and marched toward us. Oh, God, I felt sick! My eyes fluttered and I stared shiftily from side to side. Jesus, hadn't David heard me? He was just putting his tongue up his sister's cunt again, making her give out little cooing dovey cries.
She sighed and looked back over her shoulder. "Oh, hi," she said. "Alan, Connie, this is my friend Barbara from school. Don't call her Barbie, though. She doesn't like that. Barbara, say hi to our mom and dad."
So casual it made my heart skip two or three beats running! I looked up finally, at the man and the woman, and things began to click slowly, but finally clicking. "Hello," the woman said, offering me her hand. I pulled the jumper tighter against me and gingerly shook hands with her, then with the man.
"So nice to meet you," the woman, Connie, said. "Have David and Dierdre kept you entertained?"
The family resemblance was obvious. Both parents were dark-haired, healthy-looking, as beautiful as their children. The man was tall and very well-built, his wife tall and slender with small, firm breasts obvious under her clinging silk shirt. And they didn't seem at all astonished by the scene they'd walked into. Not at all!
"Hello, David," the man said. "Or aren't you going to speak?"
The boy raised his face from Dierdre's twat. He licked his lips, then said: "You always told me it wasn't polite to talk with my mouth full."
"Who says the younger generation has forgotten its manners?" the woman smiled. She looked down at the patio floor, then bent over and picked up the bra Dierdre had taken off. "Yours?" I shook my head. So did she. "What would Frederick's of Hollywood do without my daughter's business?" she wondered aloud, running her fingers through the cutouts in the flimsy nylon garment.
"Come say hi, Daddy," Dierdre called, pushing her brother out of the way. She turned around, slinked her leg over the side of the chair and shot him a wide open beaver. To emphasize the point, her hand dropped into her lap and a lazy finger began to stroke the salmon-pink vulva on display.
"Excuse me, Barbara," Alan Banks said courteously, and he stepped between his wife and me. In a moment he was on his knees beside Dierdre, licking the pussy she had offered him so frankly. My eyes were doing a lot of bulging today.
David shrugged and, naked as he was, went to his mother. He was a few inches taller titan, and she leaned her head back to accept his kiss of greeting. Jesus! When did boys kiss their mothers like that? He held her by the cheeks and he smeared his mouth all over hers while she strained fiercely against him. Her hand dropped down and she started to pet the limp dangle of his rod. And suddenly it wasn't so limp any more and just as suddenly I found everything making final sense in my head.
The Banks kids didn't have to worry about getting caught by their parents in the sex act, because their parents already knew about it! Even more, their parents were definitely involved in the goings-on. Alan eating his daughter. Connie hardening her son's cock. Oh, wow, this was no ordinary family!
My first reaction was shock. I'd accepted the brother and sister sex that I had been allowed to share in, but seeing the parents involvement so plainly was a little more than I was ready to take. Man's head bobbed up and down in Dierdre's lap, and she was turning on, fast. She had both legs wrapped around his head, pulling him into her, and he had his hands on her tits. The nipples were little brown spears of erection between his pinching fingers and her face betrayed her delight.
I looked back at Connie and David. He'd just unbuttoned his mother's blouse, flinging it open, and his hands found her small, round tits, cupped in see-through pink nylon. In a moment, he'd pushed the elastic bra up, out of the way, and he was handling her bare boobs the way a boy isn't supposed to touch his mother. Or so I'd always assumed.
"You don't get enough, do you?" she murmured, pumping his pecker. It was up big and hard now, red in her pale fist.
"I'm a growing boy," he said lightly. "I never get enough of anything." He slipped the blouse off her shoulders and she let go of his penis long enough to allow the shirt to fall clear.
"We're not very polite," Connie said then. "Aren't we forgetting our guest?"
That was when I realized that I was still hiding behind the jumper. Somehow, it seemed on the hypocritical side, so I let it drop and crawled nervously to my feet. There were four other people out here poolside now, and I didn't feel any more naked.
"Oh, she's lovely!" Mrs. Banks cried. She came toward me, nipples erect and bare, and she took my land. "Alan, don't you think she's just adorable?"
Alan Banks turned around. He looked strange, but somehow not too strange, looking at me with Dierdre's ankles overlapped in front of his Adam's apple. "Very," ho said, lifting his eyebrows. His eyes were green – the whole family seemed to be green-eyed – and they sparkled. I was being appraised, and I knew it, and it didn't feel bad at all.
David took my other hand. "Barbara's all right," he drawled. "And that's an expert opinion."
I giggled involuntarily, but I could feel the ice breaking and the distances contracting rapidly. Connie Banks regarded me with her straightforward eyes, and I returned the stare in spades. She was a beautiful woman – about thirty-nine or forty, I guessed, though she could have been older or younger. Her body was trim and youthful, no matter what her age might be, and her face was attractive. The wide set eyes, the small, determined nose, the frank mouth, the plumb of her chin she interested me. In some ways she gave indications of how Dierdre would look at this age, and I felt a growing certainty that if I'd hit it off with the daughter, I stood to hit it off with the mother, too.
