Kathy Harris - Fun with daughter

Margo kept her word. She told Mark that their sister was ready to have her cherry popped. The first day everyone else had something to do away from the house, leaving it entirely to Nikki and Mark, the brother and sister went for a swim in the family swimming pool.

They dove into the water and swam vigorously, more or less ignoring each other at first. Both of the teenagers were trying to work off their excess sexual energy.

Finally they stood in the shallow end of the pool, their heads and shoulders above the water, facing each other. Mark felt an ache in his balls, and the blood pumping into the head and shaft of his cock.

Nikki had taken note of the large bulge in the crotch of her brother's bikini briefs. She had never seen a real cock before, and she could hardly wait to get her first glimpse of Mark's, although she still was not at all sure that she was ready to be fucked.

Mark reached out and placed his hands on the sides of the girl's slender waist. His hands were large and as he held his sister around her middle, the tips of his middle fingers almost touched at the small of her back.

"Margo told me what you want, baby," Mark said huskily, thinking how sexy his sister looked in her skimpy bikini.

"I-I don't know, Mark," the girl said.

"Shhhh, just leave it all to me," Mark said soothingly as he pulled her up tightly against him.

Her hands instinctively moved up to the back of his strong neck and she laced her fingers together. She found herself rising up on her toes and pressed her tits against his manly chest.

Mark bent down a bit and their mouths touched. The teen's cock grew thicker and harder as the teenagers kissed for a moment and then stuck out their tongues, tongue-kissing each other over and over again. Nikki's nipples were making visible bumps in the top of her bikini, and Mark groaned as he felt the rock-hard nips crossing against his muscular chest. Mark and Nikki rolled their tongues together erotically, holding each other tight. Nikki could feel her aroused blood pumping downward in her body toward her crotch, and she knew that her pussy was swelling.

"Mmmm," she moaned into her brother's mouth.

The virgin felt her nips throbbing and burning against her brother's chest, demanding to be caressed by the teen's fingers and mouth.

The girl's pussy was flowing with fuck juice now. She knew that her bikini panties were soaking wet, not only with pool water but with cunt sauce.

Nikki felt her clit growing to three times its normal size, and it was pushing out from its fleshy sheath. The teenaged girl thought, with a pang of hope, that perhaps her sister was right after all. Maybe, just maybe, the fact that Mark was her own brother would be such a turn-on for Nikki that she could match his passion and lay to rest once and for all her fears of being gay.

Mark had a raging hard-on crammed inside his tight briefs. It felt to the teen as if his cock were going to tear right through the material at any second.

The brother and sister continued to tongue kiss each other for long moments, turning on more and more. Then they climbed out of the pool and sprawled together on a broad chaise lounge near the pool.

Watching each other hornily, they quickly tore their suits off and Nikki gasped with sheer sexual excitement as she saw her first cock… her brother's cock.

A full nine inches of throbbing cockmeat was standing at attend on, jutting straight out from the teen's bushy loins. His prick was thick, too.

Nikki broke out in a sweat as she wondered just how far her virgin cunt was going to have to stretch to take that mighty prick. She swallowed hard and stared at her brother's balls, which dangled low beneath the base of his prick. Her mouth began to water as she saw that the entire length of Mark's prick was bobbing up and down with sexual anticipation.

"Ohhh, Mark," she said throatily, feeling her pussyjuice rolling thickly and hotly down the insides of her naked thighs. And she groaned as she felt her clit twitching violently at the top of her pussy-slash.

"Unh, oh, baby, you're really something! I've never seen you naked before, but believe me, I've wanted to!" the teen cried.

The girl's inner cuntlips were so swollen with lust that Mark could see them dangling out of her pussy. He couldn't believe how almost bald his sister's cunt was. He had never fucked such a pussy and, for some reason, the idea of fucking one now made the ache in his balls increase. Suddenly, Mark's cockhead snapped upward, slapping him in the belly.

"Oh, God!" Nikki groaned, rising to her knees.

She licked his balls, and then sucked them while her brother lay back in the chaise lounge, groaning with excitement. Nikki thought about sucking him off, but she wasn't ready for that. She didn't know if she would ever be ready for that. The thought of sucking a guy's cock and swallowing his cum still made her feel sick to her stomach. She lay back in the grass now, her cuntjuice dribbling out from between her puffy cuntlips, and running into the crack of her ass.

Mark stared down at his virginal sister, feeling his prick throbbing harder and harder. His cum-slit pulsed relentlessly, and his heart raced.

He watched as his sister spread her legs wider and then he fell to his knees between her splayed thighs. He sprawled on top of her and they both moaned with incestuous pleasure as they pressed their naked bodies together.

Mark could feel the girl's huge tits pressing against his chest and he felt her nipples, rockhard now, throbbing against his flesh.

Nikki moaned, feeling the entire length of Mark's prick pressed up against her lower belly. She shuddered, thinking just how deep her brother's cock was going to have to go to completely penetrate her cherry cunt, and she knew instinctively that deep penetration was exactly what they both needed.

For now, the horny girl was no longer trying to fight against her natural desires, no longer trying to tell herself that she may not want to fuck with her brother. She did want to very much so. But there was a bit of nagging doubt at the back of her mind, and she had to wonder just how much she would enjoy it.

The idea that this virgin fuck was a sort of test for her, that it would answer for her the tormenting question of whether or not she was a lesbian, filled Nikki with tension.

The base of Mark's cock was pressing against his sister's golden pussy patch, just above her pulsating clit. She groaned again, realizing that in just seconds the tip of her brother's prick would be lodged deep inside her cunt. She just hoped that she wasn't taking on more than she could handle.

Maybe I should have chosen a guy with a much smaller cock, she told herself. Almost before she finished that thought, she had to admit to herself that a smaller cock would not have turned her on nearly as much as the massive one pressed against her, now.

She tried valiantly to push her fears into the back of her mind, trying to think of nothing but the pleasure she was sure to experience when her brother popped her cherry for her. Brother and sister kissed each other hungrily, both of them panting like wild animals in heat.

"Mark? You know that I'm a virgin, don't you?" she asked nervously.

"Sure, baby, Margo told me. She said that you and she have made it a lot of times but that you veneer been fucked by a cock before, Mark said, his mouth and throat going dry with the exciting thought that soon he would be popping this sexy girl's cherry."

"Right."

"I feel privileged to be the first, baby," he said thickly.

"Oh, Mark, I'm so scared! And I'm afraid that if we wait any longer, I may change my mind! Please fuck me now, Mark!" the girl cried tearfully.

Mark grinned down at her, only too happy to give her what she was begging him for. He put his hands flat on the ground on either side of his sister's head and pushed down, straightening his arms as he did. He arched his back and lifted the upper part of his muscular body.
