Tom Allison: Mom in the middle

"What do you want?" Debby whispered meekly.

Dave licked his lips and smiled menacingly. He squirmed closer to her on the bed and rested his hand casually on her knee. For the first time Debby realized that his prick was swelling in his shorts, making an obscene tent as it stiffened to a full hard-on.

He did have a big dick, she thought wonderingly. A really big one.

Dave slipped his hand under the sheet. He ran it up his sister's naked thigh and pressed his finger into the still-moistened slit of her pussy.

"Well for starts you could take off this sheet!" he suggested huskily. "Always did want to see you naked."

"Dave!" Debby said sharply, staring at him in horror. "How… how dare you! You can't!"

"I can do anything I want to," Dave interrupted. "Unless you want me to have a little talk with Dad."

Debby bit her lip and stared at him helplessly. Without waiting for permission, Dave pushed the sheet away, leaving her naked.

He seemed in awe of her body. His eyes widened as he saw the size of her, enormous firm breasts, the color contrast between their whiteness and the red circles of her nipples. Gradually his gaze moved downwards, taking in her slender waist, lithe hips, long legs, the fleecy brown triangle of her cunt.

Dave grinned and slipped his finger into the clinging lips of her pussy. Expertly he pumped it in and out of her hairy snatch, jacking her off.

"Unnnhhhh," Debby moaned. Within seconds her cunt became extremely hot and wet. Her nipples stiffened with desire; her pussy walls sucked around her brother's probing finger.

Debby didn't want to fuck Dave, or be blackmailed, but she couldn't help it. She'd been so close to cumming when he'd entered the room. His big dick was rock-hard now, and looking at it bulging in his shorts turned her on. Deep down inside she already wanted him to fuck her.

"Stop it, Dave," she whispered. But her words were meaningless, and both of them knew it. "Unhhh no… don't do this, not to your sister… ahhhhh, Dave…"

Dave withdrew his finger from her sopping pussy and stood up next to the bed. His expression was quite serious now. Silently he pulled down his jockey shorts. His heavy cock bobbed out, standing straight out before him like a battering ram, jerking stiffly with its engorgement of blood. The head was fat and crimson, and the cum drooled freely from its tip.

"I want you to suck my cock now," he said tersely. "Unless you want me to yell for Dad."

Debby said nothing. Her nipples ached with horniness; her pussy was a steaming, wet mess. She was all too eager to take her brother's prick deep into her mouth.

She sat on the edge of the mattress before him, her face directly before the jutting, blue-veined shaft. Debby wrapped her hand around the base of his click and squeezed it hard. She opened her mouth and gurgled as she took the mushroom-shaped head between her lips.

"Suck it," Dave murmured anxiously. "I mean it, Sis, I got you where I want you. Suck my dick hard!"

Debby sucked. Her hand clenched his pulsing prick and stroked it rhythmically, drawing the loose flesh up and down. Again and again she curled her tongue around his spongy prick head, kissing and licking it, darting it like an eel into his cum slit.

Dave moaned and grabbed her shoulders. Helplessly he rocked his hips, fucking his long cock down her throat.

"Ummffff," Debby moaned. More gurgling sounds came from her throat as she sucked his prick. Her mouth filled with a mixture of saliva and his dripping jism. "Oh Dave… ummfff, unnnmmgg."

"Play with my balls," Dave demanded. "Goddamn, they're full of cum. They really hurt!"

Debby dropped her free hand between her brother's thighs. Tenderly she fondled the hairy sac of his gorged nuts, rolling the balls between her fingers, as if loosening the tremendous load of cream they carried.

She was getting very horny now, as turned on as she'd been since her first night with Robbie. Dave's sexual experience was amazing. He couldn't have much of it, but he seemed to know exactly what he was doing. And there was something about sucking off her own brother that turned Debby on.

Wildly she began pumping her head up and down over its jutting, throbbing meat. Her lips pursed wetly around the pink stem of his hard-on, so tightly that her cheeks puckered and ached with the effort of sucking him.

I want to taste his cum now, she thought shamefully. Oh God, he's got me so horny… I really do want to drink it… want to feel it spurting down my throat.

Dave seemed tote reading his sister's mind. His cock twitched to absolute hardness inside her sucking mouth, bursting with seed. The teen gasped and held her head over his dick with his hands. A second later he came.

Debby had never swallowed so much jism. Furiously his white cream spouted from the tip of his huge prick, gushing into her mouth. She started swallowing it eagerly, working, her throat muscles to get it all down into her stomach.

Dave kept cumming. The squirts out of his throbbing knob were endless, as if his nuts were emptying themselves of a lifetime supply of juice. The boy cried out as he came in his sister's mouth, rocking his hips, wincing as the last white droplets burned oat of his cum slit.

Finally his cum was over. Debby licked a trace of cum from her lips and looked up at him shyly. She was sure he wouldn't get another hard-on, and she was already starting to feel terribly ashamed of herself. How could she have ever let her brother make her suck his dick, blackmail or no blackmail?

"You know something?" Dave said, smiling.

"What?"

"You have really got a huge pair of tits!"

Dave dropped his hand to his sister's milk white, cherry-capped breasts. He squeezed the spongy globes hungrily, kneading them like bread dough, rubbing his palms hard across her goose bumped nipples.

"Oh, Dave, for God's sake…" Debby sighed. Her nipples stiffened instantly to his touch, but she ignored it. It seemed a little silly to her that Dave would want to play with her tits after he'd just shot such a big wad in her mouth. "What're you…"

"They're really huge," Dave said wonderingly. He squeezed them harder, staring at her tits intensely. "They're so firm too. Shit, I'll bet you, got the best set of knockers in the world."

Debby was about to push Dave's hands away and have a serious talk with him about the incestuous act they'd just committed. Then she happened to glance at his prick.

It was getting hard again! So soon after cumming, less than a minute after spurting so much cream. It was swelling straight out before him, stiffly and proudly, the mushroom-shaped crown again filling with cum and blood.

"Oh Jesus, Dave!" she whispered in awe. "I can't believe it. You're getting another boner!"

"I know that," Dave murmured. "I told you. Your body really turns me on, Sis."

Debby completely forgot now that Dave was her brother. All she could think of was that he was the first man she'd ever heard of who could get two hard-ons in a row.

Her pussy was getting wet again, aching and warming between her shapely thighs. Unconsciously Debby lifted her hands to Dave's stiff cock and stroked it up and down.

"I get to fuck you now," Dave whispered. "Get on your hands and knees. I'll do it to you just like the dogs do, just like Robbie fucked you the other night."

Debby didn't even think of scolding Dave for his crude words. She turned on the bed and squatted on her hands and knees as quickly as she could. Her cunt was burning now, waiting for the invasion of her brother's gigantic superman cock.

Robbie knelt on the bed behind her. For several seconds he stared at the inviting spectacle of her nakedness. Debby's round, peach shaped ass wiggled with eagerness, the cheeks jiggling with the slightest movement of her body. Her legs were spread wide apart, and between them he could see the hairy mouth of her cunt, the tight, pink slit he would be sinking his aching dick into any moment.
