Don Scott: Sisters hot for fun

Marcy did not resist when Tony turned her over so that she was on her stomach on the floor of the van. Her tits pressed against the carpeting, hot tingles coming from her moist nipples which scraped against the coarse fabric.

"I think you are so beautiful," Tony whispered, his hands roaming over Marcy's succulent, tight asscheeks. "SO damn beautiful!"

The words of praise delighted Marcy. She felt her denim jeans being pulled down and raised her hips up to assist her brother. Soon, once again, her pants were crumpled up at the tops of her knees, just like they had been when she got fucked doggie-style by Luke.

Marcy shivered and moaned when her brother continued finger-fucking her seething pussy. He stabbed his finger deep into her cunt as she lay on her stomach, then took the lubricated finger and rubbed the pussyjuice against her asshole.

"You make me so horny," Tony whispered. A high-pitched gasp of surprise escaped Marcy when her brother slowly but forcefully shoved his finger into her asshole. He fingered her ass with one hand as he used the other hand to open his pants and bring his hard-on out.

It had been a shock to feel Tony shove his finger into her ass, but the shock she felt then was nothing compared to the horror that ripped through her when he flattened himself over her and the huge head of his prick was sliding between her quivering asscheeks.

"Tony! Tony, what are you doing?"

Marcy didn't get a verbal response. She felt the cockhead miss its mark, sliding up between her asscheeks, unable – at least on the first attempt – to penetrate her asshole. She shook her magnificently curvy ass, squirming beneath her brother, wondering if she should really try to get away from him or if she should take his prick into her asshole, like he wanted her to.

His lips were at her neck, gently but insistently nipping at her tingling flesh. Judging from what she could feel of his cock as it was pressed between their bodies, throbbing in the crevice of her asscheeks, Tony's cock was just as long and thick as Luke's.

"I've got to fuck you in the ass," Tony hissed, his breath hot against the side of Marcy's face. "I've just got to! I can't help, myself."

Though the thought of taking nine long, thick inches of cockmeat into her ass sent shivers of primal fear through Marcy; she couldn't help but wonder what it would be like to have such a big prick, especially a prick belonging to her own brother, into her ass! She had gotten her ass fucked before, though it wasn't a common occurrence, though she had never taken on a cock the size of Tony's before.

"I've got to fuck your ass, Marcy! I've dreamed about it for so long! Dreamed about shoving my cock into you just like this, just like we are now!"

Marcy tried to get her knees beneath her, but Tony's weight was too great for her. She writhed, her tits scraping painfully against the carpeting as Tony bit hard on her shoulder, reaching down to guide his fiery prick to the entrance of her asshole.

His knees were outside her own, preventing the big-titted teenager from moving very much. As she squirmed and twisted her body, every action she made turned Tony on more and more.

In her mind's eye Marcy could see herself and the vision that played like a movie projector in her mind fascinated her. She saw her leather knee-high boots twitching on the floor of the van, toes down. She saw her jeans crumpled at her knees. She saw her big tits swelling out beneath her arms as she was crushed to the floor of the van. Tony's mouth opened wide as he bit her shoulder, and Marcy saw it as well as felt it. And, horrifyingly, she saw the bullet-shaped head of his cock, pushing her asscheeks apart and driving into her butt.

"Unnnnn!" Tony grunted, forcing his hips down.

For a second Tony thought his cock would bend, that his sister's asshole was just too tight for his big prick. But then his cockhead slipped into her asshole and he felt her stretching around the shaft of his prick. After that he could push more of his red-hot cock in her ass, and with a few pumps he was able to bury all nine quivering inches of his cock into his prone, trembling sister's asshole.

"Tight! Your ass is so tight!" he hissed, shoving the full length of his cock into the teenager's ass, then resting there.

Her asscheeks were a smooth cushion for him each time he tossed his hips down, sinking his cock in Marcy's butt. Tony had always loved fucking women in the ass, but no woman he had ever fucked in this fashion before had turned him on as much as he was now.

Marcy could feel her asscheeks being spread wide apart by the heavily veined shaft of her brother's cock as it lanced into her, sinking into her ass until his cum churning balls slapped heavily against her cuntlips. Each time he bore relentlessly into her, her hipbones scraped against the carpet as her brother lanced down into her, driving his cock full-length into her ass.

"Uh!" Marcy gasped, feeling the breath being knocked from her lungs as Tony's muscular body slammed down against her own.

Her mind was spinning as she kit the long, thick cock sliding to and fro in her ass. The first sharp pangs of agony that had ripped through Marcy were gone now, though the throbbing in her asshole was a steady reminder of the pain she had initially felt. Now, each time the throbbing prick lanced into her asshole, Marcy was overpowered by a delicious combination of pain and pleasure, of being forced to have her asscheeks spread wider apart than was comfortable and of being filled completely with a hot, hard cock that was lusty because of her own incredible physical charms.

"So tight! So tight! So tight!" Tony chanted in Marcy's ear as he heaved above her, driving his cock in and out of her butt, throwing his torso at ha until he collided with her straining, wide-spread asscheeks.

Each time her brother pushed the entire length of his cock into her ass, Marcy felt his body quivering with short jerks. She could tell that he was on the verge of literally going out of his mind with lust for her.

Her cheek was pressed against the floor of the van as Tony ass-fucked her. His tongue slithered in her ear and Marcy shivered, enjoying the slick caress of his tongue, which was in sharp contrast to the harsh, brutal sensations she received from his fiery prick.

As she shivered on the floor of the van, Marcy felt her brother's hands roaming over her body. He rubbed her arms and shoulders. His right hand slipped under her arm to feel the swell of her big tit, which was being mashed and flattened out against the carpeting. Though he wasn't able to reach her itching, tingling nipple, his fingertips still brought lusty sensations from the horny blonde teenager.

Before long Marcy found herself raising her hips just a little to meet her brother's pounding thrusts of cock into her ass. Each time she did this, his weight slammed her down against the floor of the van, and though her hipbones protested with pain, there was something primal and erotic about it that made the heat in Marcy's cunt grow hotter.

"Fuck… fuck my ass," she heard herself say softly. "Ass-fuck me, Tony! Pound me with your cock!"

Tony put his hands on Marcy's shoulders, pushing his body up, forcing her hips to mash even harder against the carpeting.

"You turn me on," said through clenched teeth, studying his sister as his prick throbbed hotly, deep inside her ass.

Tony sat up so that his knees were surrounding Marcy's hips. He put his hands on her asscheeks, squeezing the tight, succulent mounds of flesh, watching his prick flexing inside her butt.

He started rocking back and forth, moving his hips just an inch or so, sliding his cock between the teenager's asscheeks, sitting on his own feet.

"Ass-fuck me," Marcy said, finding it easier to breathe now that her brother wasn't stretched out over her.
