At any other time, Laura thought, this would have been enough. But this time she had given Karen the license to do her worst, and unbelievably, even after she had freed Laura from the gag and handcuffs, she rolled Laura onto her stomach and began fucking her in the ass with the huge dildo. Laura was so destroyed already by the several violent orgasms she had had that she could barely resist.

"Ungh! Ungh!" Karen grunted, driving the huge dildo deep into Laura's ass, making Laura wince and groan with each sharp thrust.

"Ohhnn! Ohhnggg! God . . . ungghh! Oh . . . Karen, unggh oh please! Please stop!"

"Honey, you're going to come again, you're going to come again!" Karen panted.

Suddenly Laura also felt the marbles sliding back into her pussy. Karen was pushing them into her, underneath the huge stalk of the dildo. Then she flicked on the switch, and Laura went into convulsions, coming again with renewed violence, almost an unbelievable violence, her body ripped apart by the most excruciating spasms of pleasure so intense it differed little from pain.

Bruised, limp, exhausted, Laura felt Karen rolling her onto her back again and, after ripping out the marbles across Laura's clit, giving her another quick, jolting orgasm, she shoved the huge dildo back into Laura's pussy. Then Karen removed the nipple clamps so that she could suck and bite Laura's nipples while she raped her.

Laura had never taken such abuse, even from Eric and Rob, who had both stuck their huge pricks into her pussy at the same time. Karen was relentless, fucking her savagely, swallowing her aching nipples, then sinking her teeth into them just as Laura approached another climax. Laura came wrenchingly one last time, her body giving up its last excruciating spasm of pleasure before collapsing into a near-stupor of fatigue and pain.

It took her an hour even to emerge from the shock of it, even with Karen's contrite ministrations and tender caresses. Her body was bruised and wounded, both her ass and pussy reamed and burning, her nipples dark and hurting terribly. There were big splotchy bruises on her breasts and her thighs.

"I'll never forgive you for that," she whispered hoarsely to Karen, finally. "You really hurt me bad."

"Mmmmm, I don't expect you to forgive me, darling," Karen murmured back, eyes glistening in excitement. "I expect you to get even. You had about eight super orgasms, by my count. I want you to get even with me."

And Laura did get even.

Only in the beginning was she gentle. She pulled Karen down on her back, kissing her mouth, her neck, her beautiful smooth black shoulders, then her marvelous large firm breasts. She held them in both hands, kissing every inch of the smooth dark hard melons, then tonguing and sucking Karen's large black nipples until Karen was panting and moving her head back and forth.

"Oh god . . . Laura, it feels so good!" she moaned, watching Laura's mouth on her breasts, watching Laura tease her erect, wet nipples with her teeth. "Yes . . . yes!"

But Laura did not wait long to pay her back. Without even tying or handcuffing Karen, she began to assault the girl's beautiful breasts. She sat on Karen's stomach, bunching Karen's breasts up in her fists, squeezing them mercilessly, and then sank her teeth into one bulging black nipple.

"Aoownngggg! Owwwnncchh! Oh shit!" Karen cried out, tears coming to her eyes.

Laura bit the other delicious, protruding nipple and got the same response.

"Oh god . . . oh god!" Karen wept. "Oh shit . . . it hurts!"

"'You done axed me to hurt you, Miss Karen'," Laura teased her maliciously. "If you think that hurts, you better beg me to let you go right now."

Karen shook her head vigorously. "No . . ." She looked down at her wet, pointing nipples. "Do it again."

"You're kidding."

Karen glared at her. "Do it again."

Laura found the two pairs of handcuffs on the floor. "You're going to wish you'd never brought these," she said.

Laura used them to handcuff Karen's ankles to the bedposts, placing her head at the foot of the bed, then splaying her thighs and fastening each ankle to the opposite bedpost. Her beautiful, juicy black pussy was exposed, vulnerable, her wet cuntlips parted, revealing the glistening pink insides.

"God . . . I want you to eat my pussy, Laura," Karen panted. "I want you to eat my pussy before you rape me, please. I'm so close. I could come, if you just tickle my clit with your tongue. Please."

"Oh, is she begging now?" Laura smiled.

Karen's hands were still free, and she ran them all over her naked body, cupping her breasts, twisting her big glossy nipples, then pulling apart her cuntlips for Laura, exposing the juicy inner channel of her pussy, trying to tempt Laura.

"Suck me . . . eat me," she begged.

And she was wildly desireable. This was the tempting body that had got Laura into all this in the first place, into girl-girl sex, into endless complications of the heart and seemingly unquenchable lust for black beauties. Laura had wanted her then, and she wanted her now. Even exhausted and in pain from having been raped herself, she wanted to obliterate herself in a wild orgy of fucking with this beautiful girl.

But the fact that Karen wanted it so badly was enough to excite Laura's own streak of cruelty. She was determined that Karen would not come until her need was ten times as great as this, and would be sweetly, and even not so sweetly, tortured ingeniously along the way.

Patiently, she tied Karen's wrists to the frame of the bed, then squatted over the girl's heaving belly again, pinching her fat, glosssy, bulbous nipples, sucking them, biting them, bring gasps, sobs, then hysterical whimperings from deep in Karen's chest as she watched Laura's mouth on her ravished breasts and felt Laura's teeth on her sensitive nipples.

"Oh god, Laura, you're hurting me!" she moaned, gnawing on her lower lip, wincing, grimacing as Laura squeezed the beautiful naked globes.

"Time for the clamps, eh, my pet?" Laura said menacingly, reaching down on the floor for them.

In no time she had both Karen's nipples clamped in the tight pincers. Water sprang to Karen's eyes. Laura tugged the chain between the clamps, watching the anguished look on Karen's face.

"Ouchh! Oh . . . Jesus!"

Now Laura drew the bristly jute rope from the bag, which Karen had for some reason forgotten when torturing Laura earlier. Quickly she tied it in a girdle around Karen's waist, then pulled a strand between her thighs and up into her pussy, pulling on it hard and watching it bite into Karen's open, wet cunt, hearing Karen moan and watching her twist.

Intent on doing something Karen had once done to her, she fed the rope under the chain between the nipple clamps, then fastened it tightly, so that every time Karen moved, the rope bit into her tender pussy and at the same time yanked the nipple clamps. Karen knew what was happened, and tears poured down her cheeks as she watched Laura's hand on the rope.

"You bitch," she swore tremulously, then stronger. "You white bitch! You're killing me!"

Laura pulled the rope hard, twice.

"Anngghh! Onngghhh! Owwnncchh!" Karen cried out.

"Are you going to come?" Laura smiled.

"Oh god . . . yes! Do it harder! Please!"

But Laura let the rope fall limp from her hand. "You're not going to come yet, you naughty girl. Because I'm going to whip your pussy to make you come. I'm going to whip it hard."

The words excited Karen wildly. Her entrapped body began to shiver involuntarily.

"Gag me, I'll scream," she whimpered to Laura.

Neither of them liked to gag the other until the last moment. They each enjoyed the tormented whimperings and moanings of the other in the grip of sublime sexual torture, and they prolonged the use of the gag as long as possible.

"I love to hear you scream," Laura whispered. "And beg."

Now she drew out the whip, and for the next five minutes Karen underwent the most excruciating torture as Laura teased her clamped nipples and her roped pussy and every other exposed part of her luscious naked body with the tip-end of the whip. And yet never did she administer a stinging snap or blow, but instead tickled and threatened Karen's body until Karen was mewling and quivering in a hot frenzy of sexual arousal.

But Laura knew that the hard blows were now unavoidable. She quickly moved to fasten the gag in place, and Karen's eyes glittered with terror. Laura bent down and removed one nipple clamp from one huge, twisted, sore nipple. She licked and tongued Karen's wounded nipple, then sucked it, harder, and harder, bringing first mewls of pleasure followed by sharp gasps of pain from Karen's throat.

Then, abruptly, Laura released Karen's breast from her mouth. She brought the whip up about a foot above Karen's wet nipple, then snapped it very sharply with the tip. Karen grimaced and howled into the gag. Laura snapped it again. Then a third time.

By now Karen's face and the gag harness were both wet with tears. Her luscious body writhed in pain as Laura roughly replaced the clamp, showing no tenderness, letting the pincers dig cruelly into Karen's sensitive nipple. Now she unclamped Karen's other nipple and did the same to it, bringing muffled shrieks of pain from Karen. This time after whipping Karen's nipple, Laura lowered her mouth to it again and sank her teeth into it, torturing Karen's breast further and bringing a fresh shriek of pain from her throat.

Next Laura grasped the rope, yanking it hard, pulling the bristly cord across Karen's distended clit once, twice, three times. She yanked it so hard that Karen's pelvis came up off the mattress. Hysterical mewls of pain came from the girl. The delicious round, engorged, pink nub of her clit, which Laura had sucked so many times, was crushed and mangled by the coarse rope, and her hips were quivering uncontrollably.

Laura released the rope, letting Karen's pelvis fall back to the bed. She knew it couldn't be strung out any longer. Karen had almost come just now, from the feeling of the rope squashing her clit.

Laura again grabbed the rope with her left hand, pulling down on it this time so that Karen's clit was fully exposed and the upper part of the rope pulled sharply on the nipple clamps. Then, giving Karen, who was already crying and moaning from the pain in her breasts, only a second or so to anticipate the climax she craved, Laura brought the tip of the whip forcefully down on Karen's clit. She smacked it hard, three, four, five times.

By the fifth blow Karen was coming, her body thrashing and writhing, wracked by convulsions, sensations so intense, Laura knew, that the difference between excruciating pleasure and pain was no longer clear.

"Mmnngghiieegghhphhh! Ongghh! Annghmmffggnneiiee!" the poor girl screamed into the gag, wrenched by a ferocious climax.

Laura dropped the whip and squatted between Karen's splayed thighs, now sucking and tonguging her inflamed clit, unable to resist the opportunity. She loved eating Karen's sweet black pussy and couldn't let this episode go by without doing it. But she licked and sucked her hard, bringing Karen up short in the middle of her dying fall from her previous violent orgasm, giving her a fresh one that seemed to grip her whole body and shake it sharply.

And now in the lull after it, she pushed pillows under Karen's ass, uptilting it, making Karen's asshole available. Then she greased the vibrating marbles again with K-Y jelly and, after opening Karen with one long forefinger in a way that made Karen moan and quiver, she slid the balls into Karen's ass. Karen knew what was coming, and the anticipation made her mewl and shake.

Fascinated, feeling a fresh spurt of wild horniness herself as she did this, Laura flicked on the switch and slowly drew the marbles out of Karen's ass and up across her clit. Karen nearly went insane. Her hips churned so violently that Laura almost couldn't keep things under control. Karen came sharply, twice, her body buckling and surging as the spasms wrenched her.

And now Laura was ready to fuck her hard. She found the four- pronged, bowed dildo under her bed and crawled between Karen's thighs again to position it properly. First she inserted the forward prongs into Karen's asshole and pussy, yanking the chain between the nipple clamps too, bringing moans and fresh tears to Karen's eyes as the tight clips pinched her nipples mercilessly.

But now, before inserting the other prongs into her own body, Laura unfastened the nipple clamps and tossed the apparatus aside. She wasn't going to deny herself a full feast. Now she carefully slid the prongs into her own pussy and ass, biting her lower lip and groaning softly as they penetrated her.

"Unnhhhh! Oh god!" she gasped. "Oh god, honey, I'm going to fuck you hard, very hard!"

Karen's eyes widened. She nodded her head vigorously, beginning to churn her hips in a frantic fucking-motion. Laura began fucking her back, and in seconds the bed was rocking like a ship as they pushed their groins together wildly, gagging as the huge dildos penetrated their bodies.

Now Laura scooped up Karen's luscious, tortured breasts in her hands and began to torture them again, this time with her mouth and fingers. She squeezed them fiercely, and sucked and pinched Karen's big, bulbous nipples as she fucked the girl.

After about a minute of this wild, uncontrollable, frantic fucking they were both about to come again. Laura now began to bite Karen's nipples, feeling herself sink into a nearly-insane frenzy of sexual mania, something she had only felt a few times before. She lunged her pelvis into Karen's, sinking the dildoes deep into both of them, and tore at Karen's wet, erect nipples with her teeth.

Karen began to come first, a massive orgasm that made her briefly lose consciousness. Laura was close behind, scorched by fierce spasms of coming that erupted inside her body and flowed outward into her quivering flesh. They were glued together, their bodies shuddering unbelievably as the intense rapture shook them.

When it was over, Laura disentangled their sweaty, exhausted bodies, but she did not free Karen from her bonds. She removed the gag so that the girl could breathe, but left her wrists and ankles secured to the bedframe.

"You can let me go now," Karen finally croaked softly, looking blasted by the sexual attack she had experienced.

Laura simply shook her head, without speaking.

"Please . . . Laura. Let me go. My body hurts."

"All those orgasms," Laura smiled. "And it hurts?"

"You hurt me bad, you bitch," Karen murmured, her eyes veiled with sex, as if it were impossible to say so without recalling the unbelievably intense orgasms such torture produced in her.

"I'm going to hurt you some more," Laura murmured back. "I'm not finished."

"Oh no . . . Laura, please," Karen said pathetically. "I really hurt bad. You just about chewed off my nipples. My clit is throbbing, you whipped it so hard. It burns."

Laura was tired too, but during the next half hour she found three or four more ingenious things to do to Karen's enchanting naked body, and Karen came about six more times.

Laura whipped her sore nipples again, bit them again, whipped her cunt, her clit, raped her savagely with the huge double-dildo in the ass and pussy at the same time, then fucked herself with it while fucking Karen in the ass and pulling the vibrating marbles slowly out of Karen's cunt. Karen suffered agonies and had several apparently life-threatening sexual climaxes in which she nearly passed out repeatedly.

By the time it was over, and Laura did free her, she was in bad shape. Now Laura felt a little guilty and began tenderly caressing Karen's wounded body.

"I know I was hard on you," she whispered. "You asked me to be."

"I know," Karen whispered back. "Don't feel bad. You've never made me come as good as this."

"Do you think . . . you can manage one slow, gentle one like we usually do now?"

Karen smiled wanly. "I don't know. I hurt bad."

Laura held one of Karen's beautiful, bruised breasts in her hand, looking at the large, gleaming nipple, so sore after what she had done to it but still so beautiful and inviting to her lips. She licked it tenderly. Karen winced at first, but then moaned softly in throaty pleasure.

"Ohhhh Laura . . . god, you're going to make me come again!" she panted.

"But this time no pain," Laura whispered. "For either of us. I love to fuck you, Karen."

But, surprisingly, after what she had been through, Karen was already holding on for dear life, keening and panting and writhing as Laura's hand rubbed her clit and Laura's mouth sucked her throbbing nipples. In half a minute she had another excruciating orgasm, painful because of the soreness of her body but sublime in its devastating consequences.

After repaying the favor to Laura, she cooed into Laura's ear. "Last time was the worst. And this time was worse than that. How long can we keep seeing each other without serious trouble happening?"

Laura had wondered the same thing. "Next time why don't we meet somewhere neutral, not here, not your place, no toys, no . . . handcuffs. And just make love. Without all the rest. And see what happens. What do you think?"

Karen kissed her smiling. "I think it'll be a hell of a lot less fun," she said. "But I'm willing to try it."

"Me too," Laura said.
