She began to stroke her clit gently but insistently, and her starved cunt responded with a steady trickled of juice. She sighed and spread her legs a little. It felt so nice… A cock would have been better, of course, but none was available. She had to do the best she could with her own hand.
Beginning to breathe harder, Karen slipped her stiff wet finger farther down between her thighs and rimmed the wet mouth of her famished cunt. Fantasies began to come to her, fantasies of Mark climbing over her, sticking his superb, stiff young cock into her… She creamed hard, soaking her finger.
"Ummm, yesssss," she whined.
She began easing her finger into her flaming wet box, pretending that her handsome young nephew was penetrating her, slowly and teasingly slipping his rigid fat young prick into her. She moaned softly.
"Yes, darling, yes," she sighed.
Mark had been sitting on the old mattress in the basement, smoking a cigarette, when he heard the floor creaking above him. Quickly he snuffed out the cigarette, leaped to his feet, and began carrying junk to the carton Karen had provided. He certainly didn't intend to break his ass on this job, but he had to keep up appearances.
Out of the corner of his eye he saw Karen peeking at him from the top of the stairs. She looked for just a moment, then crept away without saying a word.
That puzzled and irritated him. If she was going to keep checking on him, dammit, she could at least say hello. Mark's temper was in bad shape today anyhow. He was horny, and he ached to get it on with his beautiful adoptive mother, but he hadn't figured out a good approach yet.
Well, to hell with approaches. He was just going to go right upstairs and have her, rape her if he had to. Stacy and Bill were at the beach and would be gone for hours – he could trust his sister on that score. There'd be plenty of time for his conquest of Karen.
Mark started up the stairs, flushed and determined, but something told him to proceed quietly, not give her any warning. Karen had spied on him, obviously not wanting him to see her. Maybe she was doing something she didn't want him to know about.
He reached the top of the stairs and opened the door without a sound. He stood there listening, and from the living room he heard peculiar noises – sighing, soft moaning, little whimpers. What the hell…?
Mark crept toward the open archway of the living room, hardly daring to breathe. He knew something funny was going on, and he wanted to find out without Karen noticing him. Maybe she had a guilty secret, something he could use against her.
When Mark peered around the corner of the archway, he discovered his hunch was right. She had a guilty secret, all right, and it was a beauty. His aunt lay on her back on the couch, her hand thrust down the front of her pants and moving swiftly, rhythmically. She was panting and whimpering.
Mark grinned wickedly. His cool aloof aunt was frigging herself.
He waited a moment, planning just what he would do. He had her now, of course. He could use her secret to make her do whatever he wanted. But he wanted to get maximum pleasure out of it, and that required some thinking.
Meanwhile Karen was really getting into it. Impatient with the restriction of her tight pants, she tugged then down to her knees. She then pushed her panties down, too, exposing her pretty fluff of golden muff fur. That was better. With a sigh she again slipped her hand into her crotch.
Mark watched, grinning broadly. He saw his lovely but aloof aunt slip a finger into her wet hair-fringed cunt mouth. She pushed the finger into herself all the way to the last knuckle, and her lovely face contorted into a lusty snarl.
"Oooo, yesss," she whined, "yessss…"
As Mark watched raptly, she began to pump her finger in her juicy little cunt, working it in an out swiftly like a cock. Her white teeth flashed in a lusty grin, and her moans grew husky and prolonged. The poor chick was really starved for sex.
Well, she wouldn't have to wait much longer. Mark intended to give her the real thing.
He crept silently into the living room. Karen's eyes were tightly shut now as she abandoned herself to her own erotic fantasies, whatever they were. Her finger, soaked and gleaming with her plentiful cream, moved faster and faster in her aroused cunt.
"Oh, my God, yes, darling," she whimpered. "Fuck me, Mark…"
Mark almost howled in triumph. She was pretending it was him. Too fucking much! The bitch had turned him down, refused to ball him, but in secret she wanted him desperately. He couldn't pass up an opening like that.
"You called me?" he said distinctly.
Karen froze. She prayed her ears had deceived her, but as she opened her eyes she saw her nephew standing right beside the couch, leering at her. He'd seen everything, heard her calling his name. He'd caught her in that shameful act, her pants down around her knees, her finger stuck in her cunt. Oh, God, it was too awful!
"Oh, NO," Karen gasped, bursting into tears.
She slipped her cream-soaked finger from her cunt and started to pull up her panties, but Mark seized her hands and held them. He sat down on the edge of the couch and looked at her, his blue eyes hot and lusty and amused.
"Hey," he said, "no need to cry. You want me, Auntie, you can have me. You can have the real thing. Shit, you should've told me before. I would've been glad to take care of you."
Karen moaned and shook her head. "You don't understand," she sobbed. "I'm so ashamed. That you should see me doing a thing like that…"
"Oh, hell, that's nothing," said Mark. "Everybody does it. But you don't have to any more, see? I'll fuck you anytime you want it."
Karen shuddered. She knew he wasn't kidding. He'd fuck her, all right, make love to his own aunt under Bill's nose. It was a sickening situation. The boy had the morals of an alley cat.
"That's out of the question, Mark," she said coldly. "I won't cheat on my husband, and I wouldn't dream of doing it with my adopted son. Please, forget it."
Mark sighed deeply. "Wow, you are really something else," he said with exasperation. "You'll frig yourself and pretend it's me. You'll suck my cock and eat my come. But you won't ball me. That's crazy, Karen. It's buflshit. You're being ridiculous. We want each other, so why shouldn't we do it?"
He was right – she was being a terrible hypocrite. But her conscience still told her it would be wrong to fuck this boy, her blood nephew.
"Mark," she said shakily, "I know I'm not being logical, but I just can't bring myself to do it. Now, please, let go of me. That answer is no, and that's final."
He gripped her wrists even harder. "Oh, no, Auntie," he said harshly, "the answer is yes and I won't quit till I get into you. Make it easy on yourself and just spread those legs. I'm gonna get to you sooner or later."
"No," Karen sobbed, "never…"
Mark was tired or arguing. He leaped up and straddled her, his tight muscular ass resting on her big heaving tits, his crotch almost in her face. Holding her flailing hands aside with one fist, he quickly unzipped his fly and took out his pale limp prick. He let the doughy warm rod fall on her trembling lips.
"Okay," he said. "You don't wanta fuck me, you can blow me. Come on, open up. Suck me off like you did yesterday."
Karen quickly obeyed. This would buy her some time, and she wouldn't have to fuck him today. She opened her lips and let the soft warm meat drop into her mouth. She sucked him in strongly taking his limp cock all the way to his balls.
"Yeah, that's good," Mark sighed. "Suck my dick, Auntie…"
He was lying, of course. He didn't intend to let her off so easily. This time he meant to ball her, no matter how she fought or how much she protested. He was tired of her bullshit. He was so horny he could have screamed. He'd let her suck him, get him hard, and then she was in for a surprise.
Karen's hot juicy mouth felt really good around his sensitive prick. She sucked fast and greedily, obviously hoping to bring him off fast and be done with it. Mark abandoned himself to the keen pleasure of having his meat sucked, and it wasn't long before he began to grow hard.
