"Mind if I come in?" she teased.
"Sure," he said. He hurriedly unfastened the chain, acting very nervous.
"That is, if I'm not interrupting anything," Kirstie said sassily as she walked into the apartment.
"Not any more," Rick grinned sheepishly.
"We always seem to be just missing each other, don't we?" she taunted him.
"Kirstie, I can…"
But she put her finger to her lips and stopped him. "No need to explain," she said.
"I really came here looking for you," Rick said. "But she…"
"I said you don't have to explain," Kirstie interrupted him again. "I know how beautiful Marsha can be."
She gave him a suggestive expression as she said it, lingering on the word "beautiful". It had the desired effect. Rick looked only briefly puzzled before it dawned on him that she had fucked Marsha too.
"You mean you two."
Kirstie only grinned. She went over to him and brushed the fresh scabs on his back where Marsha had raked him. She bent her ups to them.
"Rut she never tore me up like this," she murmured. "You must've given him something I couldn't."
She couldn't help glancing down to watch his long enormous cock swelling, rising. Even after all the fucking she had just been through, the sight of her brother's huge prick excited her tremendously. The fact that it had just been plunging in and out of Marsha's sweet pussy became irrelevant.
"But evidently she didn't satisfy you," she whispered.
She got on her knees and fed the huge thickening tube of flesh into her warm wet mouth. She clamped her lips on the swelling head of his prick and sucked gently, lovingly. She felt it grow into a stiff throbbing monster in her mouth.
Rick did nothing to stop her. He caressed her hair and held her head gently, sliding his cock slowly in and out of her clasping lips. Both of them seemed lost in a primal moment, as if remembering the first time – long ago.
All Kirstie old feeling for her brother seemed to flood back into her as she held his warm twitching cock in her mouth, running her wet velvety tongue all over it. Oh Rickie, she thought, why can't we just fuck each other and forget about everyone else! Why does everybody else have to get in the way? I know it's wrong, but I love it! God, how I love it! I want you to take me in your arms and fuck me until the sun comes up! I wish Marsha wasn't here!
But Marsha was there. In fact, she was standing at that very moment in the bedroom doorway, stark naked, watching them. Only this time the expression on her face wasn't one of shock. Instead, she was fascinated. Her recently quenched lust was immediately reawakened by the sight of Kirstie kneeling on the floor and gulping down her brother's huge stiff prick.
Roth Rick and Kirstie soon felt her presence. Without stopping what she was doing, Kirstie glanced over at her roommate. Marsha's eyes were glazed, her sensual mouth slack. With one hand she unconsciously rubbed her breasts, with the other her pussy.
Kirstie took Rick's thundering cock out of her mouth for a brief second. "Hi," she said, her voice deep and husky.
"Hi," Marsha half-gasped.
"Do you want to… join me?"
Marsha nodded as if hypnotized. She couldn't take her eyes off Rick's massive pulsing organ. God, Kirstie thought, you'd think she'd had enough of it from the way she was screaming in there a few minutes ago. She turned back to it and licked the thick throbbing stalk once more. But I guess nobody ever gets enough of this one, do they.
She looked up at her brother's face. "You mind if we both suck it?"
He smiled and shook his head. "I'd like to see how you go about it," he said.
Kirstie winked at Marsha. "Oh, I'm sure we'll think of a way. Why don't we go in on the bed?"
Rick nodded. The three of them went into Marsha's bedroom. Kirstie removed her clothes on the way. She was surprised to find her insatiable pussy wet and itchy again. Again she had the same ambiguous feelings about Marsha being there. She wanted to curl up on the bed with Rickie and let him fuck her until she begged him to stop. Which would be never!
But when her brother lay down on his back on the bed, his huge swollen cock twitching in readiness, she and Marsha seemed to join each other naturally in making love to him. They sank down on each side of him, holding his throbbing prick with their fingers and kissing it all over with their wet sensual lips.
Rick watched them with fascination wincing with pleasure. Their pink tongues coiled around the flaring head of his cock. Kirstie had his balls in one hand, gently wiggling them. His cock was so long that each girl could squeeze the thick shaft with one hand. And they took turns sucking the head of it between their skillful lips.
But once Kirstie got her brother's cock in her mouth, she didn't want to give it up to Marsha. She knew she had been the one who had invited Marsha into this. But Christ! she thought. What else was I supposed to do? Shit, I wish she'd just go away. I want him all to myself.
She sucked Rick with all her skill, trying to show him how much better she was at it than Marsha. Actually she wanted to make him come in her mouth, so that Marsha wouldn't get any part of it. Oh honey, come in my mouth! Don't let her have it! Let me drink it, Rickie! Come, come, shoot it in my mouth!
But Marsha wasn't going to be shut out so easily. She rubbed Kirstie's dangling breasts with one hand, tweaking and softly pinching the soft swollen nipples. It felt great to Kirstie. But suddenly Marsha twisted one of her nipples so viciously that sharp pain shot through her breast. She gasped, opening her mouth, and Rick's jumping cock slipped out.
Instantly Marsha closed her lips over it and began sucking passionately. Kirstie was so angry she could hardly see straight. She knew how hard it was fighting over her brother's cock. And yet she couldn't control her anger.
"You bitch!" she hissed through her teeth.
She reached out both hands and pinched Marsha's nipples in return. She twisted the thick buds so sharply that Marsha cried out in pain.
"Aiiee!" she screamed.
Kirstie dove on Rick's wet twitching cock again, before Marsha could fight back. This time she crouched over his groin completely, keeping Marsha out. She pumped the shaft of his prick vigorously with one hand and milked his balls with the other, sucking him wildly. Oh come, honey, come, come! she moaned to herself. Come, spurt it into me, don't let her have any!
Rick was quite amused at the way they were fighting over his prick. Unfortunately, their crazy antics were making it impossible for him to keep control. Already the hot cum was boiling in his balls. And the way his sister was devouring his tool made him groan and bite his lip.
Marsha saw that there was no way she could oust Kirstie now. She also saw the incredibly intense pleasure on Rick's face. She crawled up and kissed him wildly, then dangled her firm perfect breasts in his face.
"Suck me, baby!" she whimpered. "Suck me and come! Suck my titties hard, suck me hard!"
Rick did even more than she asked. He could feel his orgasm only seconds away. He couldn't remember ever having had such pleasure in his life, and he was determined to make it the best.
He grabbed Marsha's whole naked body, grasping her squirming ass with one hand and thrusting the other into her juicy pussy lips. Then he sucked one of her big nipples into his mouth and nearly down his throat, at the same time plunging his cock up into Kirstie's working mouth. The three of them thrashed around wildly on the bed, surging and gasping, sucking and moaning.
"Ohhhnnnnn! Oh!" Marsha moaned.
Kirstie pumped her brother's stiff cock with her hand, nearly swallowing the huge shaft with her mouth. "Mmmmm!" she hummed deliriously.
When he came it was like a geyser shooting off in her mouth. Rick groaned. His body shook with fierce spasms. The whole bed rocked as if struck by an earthquake. Marsha squealed as an orgasm ripped through her. And Rick's cock erupted in Kirstie's mouth, gushing jets of hot cum down her throat.
