Dan began rethinking his ideas about the girl as Heidi's hand reached past his hip and cupped his bulging crotch. He let her squeeze and roll the hardening flesh for a moment, then stepped inside. Heidi followed him and shut the door.
"Sorry to break this up, kids," he said, "but your fun's over, and ours is about to begin."
Heidi giggled as the kids' bodies tensed with shock and fear. Karen lost her balance and fell backwards, sprawling with her dress high and her sopping, inflamed pussy appealingly exposed. Ron stood as if rooted to the floor, his stiff, saliva coated cock slowly deflating until its rosy head hung as if in shame.
Karen quickly pushed her dress down and turned wide eyes and a pale, frightened face toward the intruders. "Wh-who are you?" she stammered, her heart pounding as much from the shock of being caught sucking on her brother's cock as from the sight of the big gun in the man's fist and the huge lump in the front of his pants. The woman with him was smiling in quite a friendly manner as her eyes darted from Karen's body to Ron's limp prick.
"I'm gonna be your new dad for awhile," Dan joked, "and this is your new, uh…" He looked at Heidi. "What would you like to be, Auntie?"
Heidi unbuttoned the front of her blouse. "How about their new teacher?" she said, her face flushing with excitement.
"Yeah. Kids," he said loudly, "this is your new teacher. You may call her Miss Quim." Heidi smiled.
"Just call me paddy," he continued. "And you can bet your sweet little ass that I'll be more understanding about you suckin' the kid here than your real daddy."
"You… you're not gonna tell, are you?" Ron pleaded in a high, squeaky voice. "Please don't tell! Mom will kill me!" He looked ready to cry.
Heidi walked over to him. "What's your name?" she asked comfortingly, tending so that her huge tits swung out against her opened dress, allowing him a good view of their pale inner slopes.
"Ron," he answered, lifting his eyes up to take in the gorgeous view.
"And your sister's?"
"Karen."
"Well, Karen," she said, turning to the girl. "Would you like to make a deal?"
"Wh-what kind of deal?" she asked, looking at the woman's companion. Her mouth had gone dry at the mention of her mother being told about her newest perversion, but she remembered the warnings she'd had about strange men.
"You keep quiet when your Mom gets home. Let your new daddy surprise her, and maybe we'll fix it so she won't mind you sucking on Ron's cock."
"How you gonna do that?" Ron whispered, still feeling a little sick to his stomach with fear.
"That's my department," Dan said. "I think I can persuade your Mom to take Karen's place sucking your dick. Would you like that?"
Ron was so shocked he couldn't answer, but involuntary visions of his mother's pretty red lips wrapped around his pecker suddenly swirled through his mind.
Heidi turned to the flabbergasted girl. "And how would you like to taste your new daddy's cock, hmmmmm?"
Their real father's thick, flaccid cock had been seen by Karen only once, accidentally, a few years ago, and she wondered how anything that looked so much like one of their garden cucumbers could ever fit inside her mother's cunny. Now the girl thought about holding one that big – or bigger – and putting her mouth on it. She couldn't help feeling excited about making this big man as helpless as she'd made Ron.
"I see the idea appeals to you," Heidi said.
"Good. I can tell you he's got a very nice cock, a mouthwatering cock, in fact. You'll love how it tastes, especially since you've been munching on your brother's cock. If you liked that, you'll go crazy over your new daddy's pussy-splitter!"
"And," Dan added, "it's a great way to pass the time while we wait for your mother."
Karen watched with mingled fear and anticipation as he unzipped his pants and walked over to her. She could see the sizeable bulge in his white shorts pushing through the opening.
"Go on," Heidi urged, getting a kick out of the girl's timidity. "Take it out."
"Yeah," Dan urged, "Don't worry – I won't shoot off. I just want you to prime the pump a bit."
Karen's little fingers touched the man's shorts, and she gasped at the pulsing heat and strength they contained. Awkwardly, she managed to fish his hard, dripping cock through the opening. It bobbed up and down before Karen's saucer-like eyes.
"Take out my balls, too," Dan urged, and then groaned with pleasure as the girl's soft fingers fumbled around his sweaty, hairy nuts. Soon they were hanging over his pants, swaying as he took a step toward Karen's slightly parted lips.
The girl was fascinated by the long, fat cock. It was at least half again as big as her father's! She was so entranced she never noticed how Heidi and her brother were following her every move. She grabbed the shaft with both hands, holding it still.
"See that," Heidi whispered to Ron. "Would you like me to do that for you?" The teen nodded eagerly, switching his eyes from his sister's hands to the woman's half-exposed jugs. What a pair of whoppers, he thought, and felt his cock stiffening again.
"Now," Heidi warned, "you can't shoot off, you know. We've got to save all that nice white cream for your mother. Right?"
Ron's heart missed a beat as he was reminded that these strangers actually intended for him to stick his cock in his own mother's mouth! Then his groans mingled with Dan's as the two females started sucking.
About three-quarters of an hour later Dan heard the front door open. Heidi was in the bedroom with the kids, both of whom had promised to be quiet, and he knew they were both intrigued enough, if not frightened enough, to keep that promise.
He heard Laura's steps. Shit, he could hardly wait to get a piece of her fine ass. He felt the same way now that he had when he was fifteen and spying on his aunt. And Karen's hot little mouth had really worked him up. He'd almost come three times under her eagerly nibbling lips and ball-jiggling fingers.
He allowed Laura to get as far as the living room, then stepped from the hall and pointed the gun at her. She gasped and dropped her purse, and backed against the sofa.
"Hi, Laura," he said, hungrily eyeing the mother's full, heavy tits as they bounced with her surprised agitation. "Now, don't get excited or someone's liable to get hurt. Just do as I say, and your kids'll be all right, understand?"
"Ohmigod! Where are Karen and Ron?" she cried, starting forward. "Where are my children?"
"They're OK," Dan said. "I told 'em to stay in their room for now, so just settle down."
"W-what do you want from us?" she demanded, striving to remain calm.
"Don't worry about it," Dan said soothingly. "No one'll be hurt if you cooperate. Now, get some rope and bring it to me. I'll give you half a minute."
Laura surprised herself by regaining her composure. She wasted no time in hurrying to the kitchen and finding some old clothesline. She briefly considered grabbing a knife from one of the drawers, but realized it wasn't worth the risk. She'd never get a chance to use it, and there were her children to consider. Any sacrifice was worth making to keep them safe.
She hurried back to him with some pieces of rope in her hand. He took them and gently pushed her toward the middle of the room.
"Now bend over the back of that chair," he said. "Come on, move your ass."
Fearing what he might do to her children if she resisted, Laura gripped the chair's arms and leaned forward over the back, her ass facing Dan. He tied her wrists to the arms of the chair, then walked behind her and with one quick movement lifted up the back of her dress, exposing her lovely long legs and her plump, panty-clad asscheeks. They trembled enticingly as she squirmed in protest.
"Now I'll get the kids," he said, leaving her with her thoughts.
