"Owwwwwwww!" Ben sobbed. "Oh, God! God!"
Her finger was in! Nancy wiggled her hand against the boy's ass, her tongue stabbing against the hole in the head of his cock. The boy's belly tensed, and she felt a trickle of piss move out of the head of his cock and onto her tongue.
"Ohhhhhh, God! Please, aunt Nancy…"
Recognizing what Ben was trying to do, Nancy clamped her teeth down against the base of his cock and stabbed against his resisting asshole. Her finger moved in to the first joist. She wiggled around, her fingernail tearing across the sensitive lining, and the trickle of piss into her mouth was cut off.
"Ohhhhhhhh, Jesus!"
The boy sobbed against the pain in his cock, and Nancy relented. Her teeth stopped grinding. But her finger continued to stab, working around the lining of his asshole, joint locked within the ring of muscle. Ben tightened down against her, dragging her finger up and in.
"Jesus! Jesus! Ohhhhh, God!"
Billy and Bobby looked at the older boy, Billy's cock bobbing up and down as he stroked it gently with his fingertips, Bobby's cock buried in his sister's face. They saw Ben's look of pain transformed into pleasure, his hands grabbing Nancy's head as he slammed his cock up into her mouth, then slammed his ass back against the wonderful penetration of her finger.
"Oh, Yessssss! Yes! Yesssss! Doit! do… it!" Ben yelled.
Bobby long enough to stare at Ben as the came pumped wildly against the woman's face.
Bonnie heard her brother's screams. His head was rocking back and forth, his hair tossing, his lip bitten between his teeth as he fucked her with all of his strength, gasping against the sensation throbbing through his asshole.
"god! god! gawwwwwwwd!"
"Jesus!" said the girl, unable to see the finger in her brother's ass. "What's she doing to him?"
Billy laughed. "The same thing she did to me!"
"Owwwww! Eaggghhhh! Yesssss! Ohhhh, God!" Ben cried.
The oldest boy pounded his cock deep into his aunt's throat, rocking back and forth against her, almost knocking Nancy off balance. Her finger almost fell from his rectum, was barely stabbed back, and then popped free as he slammed an even harder blow against her face.
Nancy's ass hit the floor. But she couldn't escape Ben's cock, the boy riding back with her, falling over her face, fucking down into her throat. The delightful sensation was gone from his ass, but his balls were boiling, exploding…
"shit! Shit! I'm… coming! Cominnngggg!"
CHAPTER EIGHT
Ben came with a long sighing explosion of the air in his lungs, his cock doing its best to break the back of Nancy's head open. She gasped, her nose crushed beneath his groin, and tried to push him away, the boy a dead weight. At last he slid forward, his saliva-slick cock tailing over her now and eyes and forehead, to fall against the floor.
Bonnie came off Bobby's smaller cock, and the youngster cried out.
"No, Bonnie – don't stop! I'm almost cumming!"
The girl looked at her aunt, and then back at Bobby's crotch, and slammed the teen cock into her mouth again, sucking with all of her strength. He gasped against her, thrust as far as his slender rod would reach into her hot mouth, and collapsed against her with a sigh as his strong yet sweet own exploded against her taste buds.
"Oh, geez! Jeepers!" Bobby exclaimed.
Bonnie sucked Bobby's cum into her throat, swallowing it down.
"All right!" Nancy sat up gingerly, feeling for broken bones in her back, then she climbed to her feet. "Everybody! Up! Showers!"
Bobby sagged away from Bonnie, would have fallen like Ben if the sofa wasn't handy to catch him. He rested against the arm, wiping his mouth with the back of his hand as Ben rolled over and struggled to his feet, prodded by Nancy's toes.
"Come on, lover – up you go!"
"Jesus, Aunt Nancy! Ain't you never heard of pity?"
But the boy struggled erect, sighing, his cock still throbbing, still hard. His aunt caught his arm, directed him toward the stairs.
"Let's see – your parents room has the biggest bath."
"But our shower is bigger," said Ben. "I don't know if there's room for five of us, though…"
"We'll soon find out," said Nancy.
The boys' shower was a large square, the floor rough surfaced, easily big enough to take all three of them at the same time. Adding the females made very little extra crowding, although bodies slid against each other as they were soaped and wrestled to be under the spray. For a few minutes nothing happened but passing of the cake of soap they luxuriated under the stinging hot spray. Then Billy moved to his mother with the soap, rubbed it down across her pussy.
"Oh, yes! Baby! Wash me out good!"
Billy's face pushed against her wet tit as he obliged, reaching beneath his mother to work the soap all the way into her cunt. Nancy sighed, and thrust with her muscles, pushing the soap back into her hand. The boy then took a wash cloth and scrubbed out her pussy passage, while Bobby did the same for Bonnie.
"Oh, yes!" Nancy sighed, and caught Billy, bringing his face to her tit. "Suck me, baby! Suck Mama!"
For the first time Bobby realized the change in relationship between Billy and the woman. He looked at Ben, who shrugged, and then at Bonnie. She explained what had happened.
"You mean Billy ain't our brother?" said the amazed youngster.
"Dope! I told you that when I found the birth certificates!" Bonnie said.
"Yeah, but I didn't really believe it. Geez."
"You haven't lost a brother," said Ben punching him affectionately. "You've gained an aunt to fuck!"
"Yeah!" said the boy happily. "Geez!"
Nancy heard Bobby's words and reached out to pull the boy against her rubbing her wet hair as she pressed his face to her other tit. The two teen boys sucked down at the same time, and she sighed.
"Oh, yes, suck! Suck my titties!"
The boys ignored the water pounding against their backs as they sucked against the great globes in their faces. The two hard cocks butted against her thighs, Nancy rubbing her hands across their backs, pulling them closer, pushing them down until her tits yielded to the pressure.
"Suck! Bite them! Yeahhhhhh, bite!"
Billy obeyed instantly, Bobby not until he looked sideways and saw Billy's teeth sawing against the yielding female mountains. Nancy yelped, and sighed again as the pleasurable pain stabbed through her.
"Yes! Yes! Harder! As hard as you can!"
Billy continued to work at the flesh of the mound, dragging as much between his jaws as he could. The teen licked his tongue over the nipple only, biting down gently. He worked his face sideways until the nipple poked through the corner of his mouth, and he ground it between his molars.
"Owwwwwww! Jesusssss! Owwwwwww!"
Nancy screamed at the sudden explosion of pure pain, slamming her fist down against Bobby's shoulder.
The boy slipped, fell on his ass, stunned. He gasped as water slammed into his face, his aunt sagging against the wall to moan, her fingers sliding across her damaged nipple. Bobby felt teats stinging the corner of his eyes.
"I'm sorry!" he cried. "Aunt Nancy, I'm sorry I hurt you!"
"Oh… oh Jesus!" It was the woman's turn to sob, gasping in air. She lifted her tit, saw the marks of the boy's teeth in the spongy flesh. "Jesus! It's not your fault, baby!"
She let her tit drop, and reached down to pull Bobby to his feet, burying his face between her tits. She patted him gently, then began to stroke his back as his throbbing erection worked against the side of her leg.
"I shouldn't have hit you, baby!" She managed a small laugh through her tears. "Jesus! Next time somebody asks you to bite them, you'll know they really don't want to have you bite it off – even if they ask for it!"
