The more Ann thought about it, the more excited she got. She couldn't wait to do it. That very evening, when they had waited their customary hour for Kathi to fall asleep in the other room before they began to fuck, she brought it up to Brian.
He had been like a regular stallion lately, unable to keep his hands off her. He was already peeling her nightgown off her shoulders and squeezing her breasts, his searching mouth doing incredible things to her nipples, when she softly mentioned it to him.
"I'm worried about Kathi," she murmured.
"Why?" he asked, not stopping, sucking her greedily.
"She's been so nervous and wrought-up lately. I think she needs to get laid. It's been such a long time for her."
"It's been a long time for me, too," Brian said, dipping his hand between her thighs.
"Last night?" Ann giggled. "That's not a long time. It's been weeks for her."
"It's a long time for me," Brian said, ignoring her.
"You're so piggy," Ann panted, becoming aroused. "Wanting it all for yourself. What about her?"
"She can take care of herself."
"Oh yeah? I caught her masturbating the other night when I got up to use the bathroom."
That caught his attention. For a moment, he stopped caressing her.
"Really?"
"She was coming. Trying not to make any noise, so we wouldn't hear. I think overhearing us fuck aroused her. I felt so sorry for her."
"I don't know why," Brian said. "If she was coming, then she probably enjoyed it."
"It's not the same. You know that."
"I don't know," Brian said. "I read in a book once that women get their best orgasms from jacking off."
Ann grinned. "Well, they can be good, I'll admit. But there's nothing like feeling a stiff cock in you."
Or a woman's lips on your clit, she thought guiltily. One who really knows how to suck you, the way she likes to be sucked. For a second her mind spun wildly through her afternoon with Kathi. But now Brian was becoming quizzical. He leaned up on one elbow.
"What are you suggesting? That I go in the living room and fuck her instead of you?" he grinned.
Now's my chance! Ann thought. She looked at him hotly and licked her lips, parting them in a sensual, wicked grin.
"No," she murmured. "I was thinking maybe we could… do it together. Both of us."
Brian gulped. He liked what he heard, but he could hardly believe his cars.
"Both of us… fuck her?" he asked incredulously.
Ann nodded. She stared hotly into his eyes, trying not to lose her nerve. Would he grab the chance, or would he back down? It didn't seem to take him long to make up his mind. He suddenly grabbed her wrist and pulled her off the bed, toward the door.
"Let's go," he murmured.
Both of them were naked as they went down the dark hallway. They could hear Kathi's even breathing as she slept on the sofa.
"Brian, we have to be careful," Ann whispered. "You know, she might be embarrassed if we just woke her up and asked her to fuck with us. But if we're already all over her when she wakes up, then…"
"I know, I know," Brian hushed her.
Ann felt a pang of jealousy as she looked down at his huge erect cock. The idea of fucking Kathi really had him aroused.
"You really want to fuck her, don't you?" she whispered hesitantly.
"It was your idea, honey."
"I know, I know. It's just that I…"
"Look, baby," Brian said in a reassuring voice. "It'll be just like fucking two of you, won't it? I mean, she's your twin. Anyway, I got the idea back in the bedroom that you wanted to fuck her too. You said both of us, remember?"
"Yes."
Ann was ashamed of herself for feeling jealous. Everything he said was true. And the sight of Kathi sleeping peacefully was somehow very erotic to her. Her completely unsuspecting sister would within moments be writhing with passion.
Very carefully, Brian pulled back the blanket that covered Kathi. Her filmy nightgown clung to the curves of her body. Her full breasts rose and fell with her even breathing, her plump round nipples jutting through the fabric.
"I don't know how we can get her gown off without waking her up," Brian whispered.
"We'll have to cut it off," Ann said.
"What?"
"Wait just a minute."
She crept away and within seconds returned with a pair of scissors. She knelt down beside the sofa and tried to keep her hands from shaking as she slowly and carefully cut the nightie away from Kathi's sleeping body. The sight of Kathi's warm flesh slowly coming into view made both of them pant with lust. Finally she was naked. Ann slid the scissors under the sofa and looked expectantly at Brian, her eyes glowing with sex.
Then together they both began to kiss and stroke Kathi's naked body. Ann took her sister's full springy breasts in her hands and began softly licking Kathi's ripe nipples. Brian pried her thighs apart and immediately pressed his lips against her cunt.
Kathi squirmed instinctively and sighed in her sleep. She arched her back and moaned aloud.
"Ooohhhnnnnnn!"
Brian's busy mouth made her pussy begin to flow with juice. Her nipples sprang alive in Ann's lips. Her body undulated with pleasure. She suddenly came awake with a start as Brian's tongue penetrated her juice-pit.
"Unh! Oh!" she gasped. "What… what's going on! Who… who are you?"
"It's only us. Only us, baby," Ann cooed, kissing her mouth, squeezing her boobs tenderly.
"What… what are you doing to me?" Kathi gasped.
"Does it feel good?"
"God, yesssss!"
"We want to fuck you. Brian and me. Do you want us to fuck you?"
Instead of answering, Kathi let the pliant trembling of her body tell them how she felt. She had never felt two people caressing her at the same time before. The sensations aroused her incredibly. She pushed Ann's mouth down to her throbbing breasts again and clamped her thighs around Brian's head.
"Ohhhh Jesus, it's good!" she gasped. "Fuck me, yes, both of you fuck me. Unhhhh!"
Their three bodies began writhing together more vigorously as their passion increased. Brian tongue-fucked Kathi's wet pussy hungrily, and she began whimpering constantly. The sofa was too small for the three of them to maneuver.
"Quick, let's go in on the bed!" Ann panted.
"Yes, yes, please!" Kathi whimpered.
They hurried down the hall to the bedroom.
Ann got to the bed first. She lay down on her back and Kathi got on top of her sixty-nine fashion. The two sisters began lovingly sucking each other's cunts and squirming hotly together. Brian squatted behind Kathi's uptilted ass. Dangling his balls above Ann's face, he quickly slid his prick into Kathi's squinchy slit, making her gag with pleasure.
"Unngghh!" she groaned.
She stabbed her tongue into Ann's streaming quim as Brian fucked her own cunt slowly from behind. She could feel Ann's lips on her clit even as Brian's thick cock rode in and out of her. Ann wriggled her hands between her heaving belly and Kathi's swollen breasts. She squeezed them sharply, pinching the nipples.
"Oh! Oh!" Kathi gasped.
Her body seethed with lust. She closed her lips around Ann's greasy clit and sucked sharply, feeling her sister shudder, hearing her moan. Brian leaned over onto her back, mashing their squirming bodies together. He ripped his cock into her savagely.
"Unh! Unh!" she grunted.
They fucked wildly, like crazed animals. Their hot bodies writhed and surged together, yearning and pulsing with need. Just as she was nearing the point of no return, Kathi felt Brian slip his cock out of her. He dipped it into Ann's waiting mouth and began fucking down to her throat. Ann clasped her wet lips around the straining stalk of his prick and tried to swallow it, gagging deliriously. She slipped two fingers into Kathi's gaping cunt and began screwing her fiercely, still squeezing one of her breasts with the other hand.
