Karen took her time, as she nearly always did. Determined to make Laura's orgasm the most powerful ever, she used her skill in reducing Laura to a quivering, begging slave, who would do anything to come.

She knew how to eat Laura's pussy slowly, cleverly, licking and teasing, tickling and stroking, sucking and tonguing, pulling away, then renewing her attack. After five or six minutes of it, Laura was a shuddering mass of need. She held Karen's head in her shaking hands, pulling Karen's mouth into her throbbing cunt, whimpering and moaning deliriously.

"Ohhnnn . . . god, fuck me!" she begged. "Do it now! Ohnnnn, please please! Oh! Ungghh! Oh . . . please, Karen! Fuck me! Do it, please! Don't wait!"

"But baby, you want it to be good, don't you?" Karen teased her softly. "You want to come hard, don't you? Like I did? Don't you want me to rape you? You said you did. Like you raped me."

Laura's body tensed as she felt Karen's fingers exploring the crack of her ass, brushing her asshole, pushing, probing. She knew it was coming but was shocked when she felt one finger, then two, slip into her ass.

"Ungghh!" she grunted, tears coming to her eyes.

"You want me to fuck you here?" Karen asked softly, moving her long fingers in and out.

"Unh! Yes!" Laura gulped. "Do it!"

"Oh baby . . . oh baby, you're so beautiful," Karen murmured, tongue-fucking her pussy and fingerfucking her ass slowly.

Now Karen turned Laura onto her stomach and began kissing, sucking and biting Laura's asscheeks at the same time as she fucked Laura's asshole with her long fingers. Laura had never felt anything like this in her life. Karen made love to her naked bottom and fucked it at the same time, bringing Laura to a feverish mania of need.

"Ohhhnnnn god . . . ohh god!" she moaned, pushing her face into the sheet and clenching her teeth as Karen's mouth and hand grew rougher. "Ungghh! Oh! Unhhh! Oh yes!"

"Oh baby, you're going to come so good," Karen murmured to her, now shifting their bodies once again so that she could get her mouth and free hand on Laura's aching breasts.

Now she had Laura in the same position Laura had had her in. Laura was locked in Karen's arms and legs, her whole groin splayed and vulerable, with Karen's fingers up her ass and Karen's thumb in her wet pussy. Karen's knuckle rubbed hard against her tender clit. "Oh god . . . I'm so close!" she whimpered to her tormenter, kissing Karen's mouth passionately when Karen's face came close. "I'm going to . . ."

"I know, baby, I know. Any second now."

"Unnhhh! Unnhhh!"

Finally, Karen began to mouth-maul Laura's sensitive nipples. She began by sucking them, but soon she was bunching up Laura's throbbing breasts in her free hand, squeezing them hard, and tearing at Laura's nipples with her mouth. Laura's squirming body stiffened as she felt Karen's teeth sink into one of her nipples.

"Owwnnggg!" she howled, writhing and grimacing with pain. Even though it hurt, a sharp jolt of sexual electricity shot through her body, making the pain disappear, replacing it with a fierce cloud of pleasure. Laura writhed and churned, coming closer and closer to a killing climax.

"Oh god, yes! Ohnngg god . . . yessss!" she cried out, flipping and straining, her body arching and bowing, quivering uncontrollably as Karen really turned up the heat.

Karen jabbed her fingers deep into Laura's ass, mauled Laura's erect clit with her thumb knuckle, and sucked and bit Laura's tender nipples so hard that Laura nearly screamed with pain. But the scream was caught in her throat as her body stiffened, shuddered, then seemed to burst into a thousand pieces as a shattering orgasm exploded inside of her.

"Nnngggeeee . . . nnggggeeee!" she keened hysterically as spasm after excruciating spasm wrenched her quivering body.

And Karen, instead of holding her while she came, kept fucking and raping her savagely, plunging her fingers up into Laura's ass, biting Laura's nipples, goading her into two, three more orgasms. By then, Laura couldn't come any more and sank back to the mattress, panting and moaning, her face slick with tears.

"Ohhhnnn . . . shit," she moaned softly, hardly able to believe what she had gone through.

And yet she knew it was the same thing she had put Karen through a few minutes earlier. She winced as Karen removed her fingers. She winced again as Karen's soft tongue licked the tender nipples she had been biting wildly only seconds earlier.

"God," Laura gasped, "I'll bet a gangbang isn't any rougher than that."

"Did I hurt you too bad?" Karen purred.

"I've never come like that. Not even with you. Although I don't know whether I'd want to do it very often. You really raped me."

"I know."

They kissed and squirmed their naked bodies together. Somehow a slow, simmering, healing fuck, after the way they had sexually punished one another, seemed to be in order.

"I still want you, though," Laura murmured.

"Feeling's mutual," Karen whispered.

The moved rhythmically together, this time feeling no urgency, just deep love and phenomenal physical need. Their bodies melted harmoniously together, and they knew each other's needs, and how to satisfy them, where to touch, where to kiss, tease, suck, probe. They took about twenty minutes to arouse one another to the aching, trembling, panting, begging stage, and when they finally shared a soft, blossoming, all-engulfing orgasm, it was a culminating experience, rounding off the hot craving and violence of their earlier couplings.

After this they slept, awakening once during the night to share a slow, languourous, scintillating fuck, then sleeping once more until morning. But in the morning, refreshed, they each had two more orgasms before leaving bed, then one more before dressing for work. By the time they left the apartment, they weren't sure how many climaxes each had had, but they knew it was at least the same number as the time before.

"I don't think we should see each other very often," Laura said. "We might kill each other."

"Two girls found dead in lesbian embrace, right?" Karen joked.

But neither one laughed very much. They were both still concerned about their apparently perverted sexual need for each other.

And yet they couldn't stand being apart. After work, Karen was waiting at Laura's car in the parking lot.

"I left my car at your place, remember?" she said. "Could you give me a lift?"

Laura smiled. "Will you come in for a drink before going home?"

Karen threw her head back, her dark eyes sparkling with sexual allure. "Not unless you promise to tie me to the bed and rape me until I beg you to stop," she murmured in a soft, throaty voice.

"That's what I like to hear," Laura teased her back. "I want to hear you beg."

They got into Laura's car and drove to her apartment. And when they got inside, Laura discovered that Karen had only been half- kidding. In the bedroom, Karen held up a plastic shopping bag.

"I got a surprise for us today," she said, mischievously.

"Really? What."

"I went to a hardware store during lunch."

She upended the bag over the bed and out fell a eight-foot coil of white rope. Laura, who had never had a kinky sexual idea in her life prior to this relationship, immediately began to feel her pulse hammer and gush through her body. Oh god! she thought. For us?

"And . . . what is that supposed to be for?" she swallowed drily.

"That is supposed to be for one of us to tie the other one up," Karen said darkly.

"Oh."

"I volunteer to be first."

"Really? I mean, for what?"

"To be tied, silly. You can tie me up and do anything you want to me. Isn't it exciting?"

Laura could hardly believe how exciting it was. God! It's so sick and twisted! she thought. Her pussy flooded with fuck-juice. Her whole body seemed to pulse with hot, frantic sexual excitement, unlike anything she had ever felt. She pulled Karen to her and kissed the black girl passionately, digging her hands into Karen's flesh through her clothes.

"God, baby, I never knew anything could be so exciting," she murmured in a husky, throbbing voice into the girl's marvelous dark brown ear.

"Tie me up and fuck me," Karen whispered, her eyes wide and glassy with sexual arousal.

Together, hands shaking, they undressed. Karen uncoiled the rope and handed it to Laura. Then she sat down on the edge of the bed.

"I don't even know where to start," Laura said nervously.

"Why don't you tie up my breasts first," Karen suggested, looking down at the beautiful, upswept mounds.

The hot blood hammered in Laura's temples as she looped the white rope around Karen's luscious, perfect breasts. She made three loops around each one, not tight enough to hurt but just enough to make the dark globes swell, and to make Karen's big, plump nipples flare and shine.

She knotted the rope between Karen's bulging, imprisoned breasts, then drew it up around the back of her neck, then down between her asscheeks and up one side of her crotch. By now both of them were panting softly, and quivering.

"Oh god . . . yes!" Karen whimpered as Laura wrapped the rope tightly around her midriff.

Then she looped it up over Karen's shoulder again, and down her back and up the other side of her crotch. Now Karen's pussylips were wedged between the two strands of rope in her crotch, swelling and splayed slightly, so that the glistening, fiery inner lips were visible.

Laura became more inventive as she worked. Now she helped Karen lie down on her side, then pulled apart her thighs by looping rope underneath her knees, knotting it, then running the rope up under the girl's shoulders. Now she pushed Karen's trussed body over onto her back. Karen's thighs were spread, her puckered, swollen pussy totally vulerable, her throttled breasts engorged and glossy, her thick black nipples bursting like overripe plums.

Her hands were still free, but Laura quickly coiled the rest of the rope around Karen's wrists, then yoked them to the girl's ankles. Now Karen was totally bound and helpless. A look of fear for the first time mingled with the raw sexual wildness in her eyes.

"I wouldn't do this with anyone but you," she whispered hoarsely to Laura. "I've wanted to. But I never trusted anyone else."

"Baby, you know I wouldn't hurt you," Laura said, kissing her, fondling the tight, hard balls of her strangled breasts.

"Ohhhnnnn . . . oh shit, I'm almost coming," Karen panted. "You tied me up. Now fuck me. Fuck me, do it hard!"

Laura began to kiss and stroke the girl's incredible, trussed up body. Somehow the tight ropes made Karen's luscious body even more desirable. Laura's tongue on the bursting bulbs of Karen's swollen nipples brought maniacal whimpers of need from deep in the black girl's chest. And when she sucked one of them, she felt Karen shudder and strain, hovering on the brink of an orgasm.

"Ohhnnnn god . . . unngghhh . . . oh shit!" Karen gasped. "Put something in my mouth. Please! I'm going to scream!"

"Oh baby!"

"Please! Then fuck me hard! Quick! Oh honey . . . I'm so close!"

Desperately, Laura searched around her bedroom for something to use as a gag. Finally, she took a fresh pair of silk panties out of a drawer, wadded them up into a ball, and stuffed it into Karen's mouth.

"Can you breathe?" she asked.

Karen nodded, eyes wide and glassy with lust, eager, hot. "Unnhhh!" she said.

Next Laura took some old pantyhose and tied the gag in place, knotting them behind Karen's head. Now Karen's voice was muffled. She could scream all she wanted. Laura returned to the bulging globes of Karen's breasts and began to suck and torment them, slowly increasing the heat, until she was softly biting the girl's huge, distended nipples, making Karen keen and wail with frantic need.

Laura was just about to make her come when the doorbell rang.
