"YES," she gasped, "yes, ball me, fuck meee!"
He didn't have to be urged. He began fucking her like a wild animal, slamming his thick meat furiously in and out of her. He pressed her hard against the wall, so that the rough brick tore at her clothing, but Stacy loved it. She almost fainted with pleasure as his thick hard dick seared swiftly in and out of her famished little cunt.
"Yeah, do it to me," she wailed, digging her nails into his shoulders. "Stick it to me, hard, HARD, motherfucker… Yeah, that's GOOD!"
She must have been hard up, because she felt herself coming almost instantly. After a week without sex it wasn't difficult for her to climax again and again. She wrapped her legs around his waist and let him ball her ferociously, slamming his hard cock-head against her tender womb.
"Deeper," she whined. "Harder, you bastard, harder!"
She must have come half a dozen times, the poor guy panting and dripping with sweat, trying to please her – but it was impossible for one man, one cock, to satisfy Stacy's endless lust. At last he moaned hoarsely and shot his sizzling load into her.
Stacy sighed wistfully. Sometimes she wondered if she'd ever get enough.
The guy withdrew, staggering back against the opposite wall, and Stacy lowered her skirt, picked up her panties and put them in her pocket. She hoped he wouldn't give her any trouble about leaving. Once she'd had a guy at the movies, she didn't want to see him again.
Just then a prowl car cruised by, and Stacy took advantage of the coincidence.
"There's my dad," she said.
The guy split down the alley. Grinning, Stacy hurried home, anxious now to see Mark and compare adventures.
She found her brother lolling on his bed, smoking a forbidden cigarette, looking impatient.
"Where the hell you been?" he said. "I got back an hour ago."
Stacy sat down on the bed and grinned. "It was a long movie," she said. "Did you score?"
Mark grinned, too. "I sure did. It was a really great night. How about you?"
"Me, too," said his sister. "Not half bad. You know, Mark, maybe it won't be so bad after all, moving in with Bill and Karen."
"Yeah, except they keep watching us like hawks," said Mark. "It's not like with Mom – she was too busy to patrol us. With them we have to sneak around all the time."
"Well, there's a solution to that," Stacy said, grinning wickedly. "All we have to do is get it on with them."
"Oh, wow," said Mark, "I could go for that. Think we could bring it off?"
"We can try," said Stacy.
"Right," Mark chuckled. "We can try." Brother and sister shook hands on it.
CHAPTER FOUR
The next morning Mark and Stacy slept in late, exhausted from their late-night adventures. Karen and Bill were surprised, then annoyed, when the kids weren't out of bed by noon.
"You know, honey," Bill said, "this just won't do. We can't let them sleep in like this every day. They ought to be up and helping with the work around the house."
"I agree," said Karen. "I don't want a couple of lazy, useless kids. We'll talk to them about it when they get up."
Around one o'clock Mark and Stacy finally showed up for breakfast, and Bill laid down the law. He told the brother and sister that they'd have to be up by eight every morning and that they must help Karen with the housework. Mark and Stacy were secretly annoyed, but they didn't let it show. They wanted to stay on good terms with their adoptive parents.
"Stacy, you can start by washing the dishes," said Karen, "and then I want you to dust and vacuum the house."
"Yes, Aunt Karen," Stacy said obediently.
"And Mark," Karen went on, "I want you to clean the basement. Come with me, and I'll show you what to do."
"Okay, Aunt Karen," said Mark.
As they left the room, Mark and Stacy winked at each other.
Karen led the way into the basement, and Mark avidly eyed her tall leggy figure as they went down the stairs. She was wearing a short cotton dress that didn't hide her ripe mature curves and her long shapely legs. She had the most exciting body Mark had ever seen.
"This is going to be a pretty big job," she told him. "It might take you more than one day. All this junk has to be moved, the floor has to be swept…"
Mark nodded, but he wasn't really listening. He hadn't come down here to clean any fucking basement. He'd come because it gave him a chance to be alone with his beautiful aunt. He'd told Stacy he intended to seduce Karen, and he meant it. This looked like a great opportunity.
"Why, look at this old thing," said Karen, bending over to fish some object from the pile of junk. "I haven't seen this in years."
She was tugging at a large framed picture, but it was wedged in with other things. Leaning over like that in her short dress, she unwittingly showed just the very edge of her panties. Mark's interest quickened. He moved closer to her.
"Let me help," he said.
"Oh, thank you, Mark," said Karen. "I can't seem to budge it. You'll be interested, though. It's a picture of your mother and me when we were little."
Big deal, thought Mark. He wasn't interested in baby pictures. He wanted the mature, grown-up Karen. He moved in alongside of her, smelling her purfume and her naturally fragrant flesh. He saw her large pointed tits heaving as she struggled to extract the photo. He leaned down and seized the photo, his body brushing against hers, their thighs rubbing.
"It's really wedged in there," he said, grunting. He pretended to make the job harder than it was. He tugged at the big framed picture, and as he felt it coming loose, he pretended to stumble.
"Oops!" he yelped, falling backwards. He grabbed Karen around the waist, as if for support, and they fell together.
They landed on a discarded mattress, Mark managing to fall on top of his aunt. He allowed his hand to slide "accidentally" between her warm silky thighs, coming to rest on the faintly moist crotch of her panties. He pressed her firmly there, feeling the radiating heat of her pussy.
Karen felt a flash of lust so strong and dizzying that for a moment she could do nothing. She'd been lusting for this boy, fantasizing about him, ever since she brought him home. When she led him down into the basement, her heart was pounding. Now he was on top of her, his hard young body pressed against her, his hand resting firmly on her snatch.
She knew it was just a silly accident, but for a moment she imagined he was making love to her. Her whole pussy boiled with excitement, and she felt herself starting to cream. Oh, no – she mustn't let him feel that.
She jerked her hips away from him, dislodging his hand, and began pushing at his shoulders. "Mark," she gasped, "get off me. I can't breathe."
He didn't move. He grinned down at her, his freckled face only inches from hers. He had reason to grin. Just before she jerked away, he'd felt the sudden rush of moisture at the crotch of her panties. It came as a delicious surprise to him. His cool aloof aunt had gotten aroused when he touched her between the legs…
"Mark, please," she said, pushing at his broad young shoulders. "Let me up. You're too heavy."
So she wanted to play games? She wanted to pretend that she hadn't creamed right through her panties when he rubbed her pussy? All right, they'd play games. He was ready with a countermove. Swiftly he lowered his face and kissed her, driving his thick wet tongue deep into her mouth.
"UMPF," Karen protested.
My God, what was happening? Her teenage nephew was kissing her hungrily, lustily, working his tongue in her mouth. It wasn't right… And yet her whole body was responding with a rush of heat and excitement. Again her starved cunt creamed heavily.
Mark prolonged the kiss, not letting her move, and she felt his hand creeping downward, getting under her short skirt, sneaking up toward her crotch. Her whole pussy flamed with eagerness, but her conscience told her that this incestuous scene must stop.
