"Wow!" she exclaimed when she'd recovered her breath. "I'm really going to have to do some more practicing, and even so, I don't think I'll ever be able to do it that well!"
Stacy's father had pulled his mouth from her tingling tit. "Why don't you start practicing now?" he asked, chuckling.
"Oh, Jim, this is terribly wrong!" Marge said.
"It seems terribly right to me," Stacy said, meeting her mother's passion-filmed eyes. "The three of us are going to have a wonderful life together. I won't interfere with the swapping. Maybe I could even start going to the parties with you. I'll bet Betty's with her parents just like I am with mine by now. Unless the three of them are still sexing it up at the party. We can get the girls and guys I told you about to join us, too. And you'll have to try the big horse cocks, Mom. You'd go for that, I'll bet. You wouldn't mind, would you, Dad? Is it all right if I call you Marge and dim?"
Stacy didn't get a verbal answer, but she felt her sexy parents' actions were answer enough. Her mother had stretched out beside her and was sucking a spiked breast, and her father had resumed sucking her other throbbing tit. She began fondling her mother's lovely titties, and pushed a hand down and began stroking her father's lovely cock. She wanted to watch her father fuck her mother at close range, and she wanted to be fucked by him again and again, but first she wanted to taste her mother's twat.
There weren't any protests when Stacy pushed the greedy mouths from her taut-tipped breasts and rolled over on her side, facing Marge. Stacy pushed Marge over on her back and began feasting upon her big boobies. She suckled one, then the other, and kissed Marge's wet mouth before trailing lower. Marge returned the tongue-lashing kiss, and Stacy saw Jim watching excitedly when she did start the thrilling trip down to Marge's crotch.
The delectable fragrance emanating from Marge's cunt was so exquisite Stacy only stared at the moist slit for a few seconds, breathing in the aroma in long, slow breaths. Marge lifted slightly, and Stacy pushed the soft lips apart with her fingertips, then lowered and extended her tongue.
Stacy licked the hot lips, first one, then the other, still keeping them spread wide with her fingers. She delved her tongue into the hot, juicy pussy, thrilling to the taste, then began drawing the folds of flesh into her mouth. She sucked as she'd so recently been sucked, trying to do as good a job, feeling she'd had some success when little moans began drifting down from the lips above.
Feeling fingers on her head, digging into her scalp, Stacy moved her mouth to the top of the twitching cunt and found the clitoris stiffly erect. The passion button had to be over an inch long, she thought, fluttering her tongue against the slippery organ. She twirled her tongue, then lapped, bringing soft little cries of joy from above.
Slipping her lips around the stiffened clit, she added sucking to her lapping, and pushed her hands around and under Marge's squirming buttocks. She grasped the firm, smooth asscheeks, and began bobbing her head. Marge began hunching and wriggling, then soon began jerking and jolting wildly.
Stacy kept sucking and swallowing the tasty secretions until Marge went limp and the clutching fingers and had been removed from her head. She lifted her face and licked her wet lips.
"Fuck her, Dad! I want to watch you fuck Mom until she climaxes again!"
While speaking the loud words, Stacy had been moving out of the way, confident Jim would go along with her wishes. She watched closely as Jim did get between Marge's legs and bury his cock balls deep in her surging cunt.
When Jim started his thrusts, Stacy got around behind him and got her mouth and tongue in on the action. He moved slowly, leaving his ass high in the air long enough for her to lick his wet, slippery, pistoning prick, and she even got in a lick at the clinging cunt lips now and then. It wasn't long before Stacy had to get out of the way, though, because he began pounding Marge through a spasmodic climax.
As soon as Marge sagged, she cried, "Fuck Stacy, Jim! You know what I want to do!"
Stacy quickly got on her back, into position to be fucked by her father, and she was sure she also knew what her mother wanted to do. She decided that before the night was over, she'd try eating Jim's sperm out of Marge's cunt. She also wanted to be corn-holed by his big cock before they called it quits.
Jim pronged Stacy's clasping cunt for all of five minutes – while Marge tongued their genitals before he spurted his hot sperm into Stacy's snapping snatch. She spawned simultaneously, giving out with loud words about how wonderful it felt.
As soon as Jim withdrew his rapidly softening cock, Marge sucked it clean of jism and cuntal fluids, then mashed her mouth against Stacy's sopping cunt. Stacy spasmed again, and again loudly proclaimed how wonderful it felt.
The three of them stretched out side by side again while resting, with Stacy in the middle, and Marge finally broke a long silence.
"Stacy, I know this is wicked, and Jim and I have failed as parents, but right now I'm as happy as I've ever been in my life."
"The same goes for me," Jim said.
"That makes three happy people," Stacy said. "And what's wrong with happiness? Nothing! I think I have the best mother and father in the whole wide world, and I want us to have the same kind of happiness again and again and again!"
They did. On and on into the night.
