When they went back inside and closed the door, Karen looked at Laura, her dark eyes smoldering.

"I recall we were doing something when she interrupted us," she smiled sexily.

Laura carefully drew shut the deadbolt lock, looking at Karen significantly. Then she drew closer, her fingers grasping the lapels of Karen's fluffy pink bathrobe.

"I believe we were," she whispered.

Slowly, she pulled the lapels open, exposing Karen's marvelous, large, jutting breasts. She cupped one in each palm, lowering her mouth to them and kissing and sucking each of Karen's large black nipples until Karen was sighing and moaning.

"Mmmmm," Laura said, "now that's she's gone, maybe we can get down to some serious business."

"Yesss!" Karen said excitedly, looking down at Laura's lips as they teased her erect, wet nipples.

"But I didn't see your bag."

"I left it down in the car."

Laura gave her a mock pout. "I have a long rope . . . and a gag, but I don't have the evil things you have."

"I can go get it," Karen panted.

"I might not let you go. I might tie you up."

"You bitch. I get so horny when you talk to me that way."

"How long will it take you?"

"Five minutes, if you let my boobs go long enough for me to get dressed."

Reluctantly, Laura released them. Karen was dressed in about twenty seconds. While she was gone, Laura found herself wondering how both of them could be so deliriously horny after what they had just gone through with Chanitra. They had literally fucked her silly for a whole hour, both of them coming at least twice in the process. But as soon as they were alone together, the conflagration started.

Karen returned in less than three minutes with her small black bag, and Laura locked the door behind her again. They went together into the bedroom. Laura shut that door too, as usual.

"How long has it been since we did this?" she asked casually.

"Too long," Karen said, stripping off her clothes.

"You're in such a hurry for me to hurt you?"

"Yes."

"How did you stand it this long?"

"I didn't. I've been using the nipple clamps and the whip by myself, at home. It's so sick."

"Isn't it sick when I do it to you?"

"No. You love my body. You love to torture it so I can come so hard. God, I need it, Laura. I need you. I need you to do it. It's not the same when I do it myself."

"Oh honey . . ." Laura began, caressing Karen's cheek, upset as she always was by the words, and by the thought of what they did together.

But she also couldn't deny that it made her blood race and grow hot, and her pussy quickly got wet all over again, as if Chanitra had never been there.

"You want to," Karen whispered, sliding one hand inside Laura's robe. "You and I spent so much time on that delicious chocolate candy that we've barely touched."

They kissed, long, lovingly, movingly.

"You're my first, I'm your first," Laura murmured against her lips. "At least I think I was your first."

"You were," Karen said, dreamily.

"What we have is special."

Karen nodded, slipping off Laura's robe, running her hot hands all over Laura's naked body. "Forget about her, about Chanitra, about whatever other little chocolate bonbon you're romancing, trying to screw. For the next two hours . . . you and I," she murmured. "You and I . . . you and I. No one can do what we do."

"I know," Laura said, barely able to speak through the hammering hot pulse in her throat.

She stooped quickly and pulled the rope out from under her bed. But Karen shook her head. She opened her black bag and took out the bristly jute rope, the one she they had used last time, which Laura had forgotten. The coarse, brutal, painful rope.

"Use this one," Karen said, eyes veiled.

"Not on me," Laura said. "It's so . . ."

"Cruel?"

"Yes."

"Use it on me. Tie up my breasts with it." She reached back into the bag and fished out the nipple clamps, linked by a foot-long brass chain. "Then these."

Each time they tied one another up, they did it differently, exploring new methods. This time Karen remained standing while Laura took one end of the bristly rope and looped it three times around one of Karen's large, gorgeous breasts. She tied it, then ran the rope behind Karen's neck and down around her other breast, so that both entrapped breasts pulled slightly apart and up.

Then Laura took more rope and looped it once more around both breasts, pulling them back together again, so that the tension of the rope pulling them apart and pulling them together was balanced, and Karen's breasts were truly strangled and throttled in the tight coils, being pulled both ways. They bulged and gleamed. Her thick black nipples protruded, flaring, looking like they would burst.

"Oh . . . shit!" Karen said under her breath, looking down at her magnificent breasts, completely strangled by the rope.

Laura realized that Karen's knees were weakening. They had never done this standing up before. But somehow standing was exciting, as if they had more maneuverability.

"Do the clips," Karen panted.

"Don't you want to sit down?"

"Yes."

"Here, on the edge of the bed."

"Yes."

Laura took the nipple clamps in her hands. She opened one and again was astonished at how hard it was to open, how strongly it pinched. Just the sight of them reminded her of their last time together, a few months ago, utterly perverted and very painful, and yet probably their most explosively orgasmic in a long series of perverted orgies.

She had felt these clamps on her own nipples, and would again today, the the thought made her almost sick to her stomach. God, they hurt!

"These things really hurt," she said. "Are you sure you want them?"

Karen's dark eyes burned. "What do you think?"

Laura opened one silver clamp and put it around Karen's large, bulbous left nipple. Slowly, she let it close.

"Ahhh!" Karen gasped.

Her eyes watered.

"You had to get the strongest ones, didn't you," Laura said. "The ones that hurt the most."

Karen's nipples were so thick and puffy, the areolas so wide and protuberant, that the clamps squeezed the whole large bud and not only the middle stem.

"Put the other one on," Karen said hoarsely, biting her full lower lip.

Laura did, and again Karen gasped. "Shit," she said under her breath.

"Does it hurt?"

Tears in her eyes, Karen looked up at Laura. "If you blew on my pussy right now, I'd come," she whispered.

"Maybe I should."

"No. Make it last."

"What do you want me to do next?"

Heavy-lidded, Karen's eyes throbbed. "I want you to fuck me. Hard. I want you to be mean to me."

"You want to wait for the gag until you can't control it any more?"

"You like to hear me cry, don't you."

Instead of answering, Laura took the chain between the clamps in one hand. She tugged it sharply.

"Awwonngg!" Karen moaned, her face contorted with pain.

Laura pushed Karen onto her back on the mattress. There was plenty of rope left, and in about a minute she had Karen's wrists and ankles secured to the bedframe. Now she paused to tease Karen's beautiful runny, pink, black-lipped pussy, tickling the slick labia with her tongue until Karen was whimpering pitifully, her hips churning and gyrating as she tried to bring herself off.

Laura had to be very careful because Karen was very close to coming, which neither of them wanted her to do prematurely. But Laura teased her, even carefully tickling her swollen clit with the tip of her tongue, then reaching up with her hand and yanking the chain that linked the nipple clamps.

"Unhh! Oh! Ouuchhnnnchh!" Karen cried out, coming perilously close to a climax. "Ohhhnnn . . . ohhh shit!" she whimpered.

Now Laura kissed her way lovingly back up the girl's beautiful dark body to Karen's throttled, bulging breasts. She licked the big, delectable black nipples, cruelly pinched by the clamps, and Karen quivered and moaned in response.

"Bite me," she whispered to Laura, her eyes imploring her. "Bite me and whip me. Ohhhnnn god . . . I'm so close!"

"If I bite you, you'll come," Laura murmured.

"Yes! Oh . . . yes!" Karen whimpered, quivering in desperate sexual tension.

Laura found the black bag on the floor and got out the whip. She held it up in front of Karen's eyes, running one finger along the thin, flexible shaft, watching Karen's body flex and shudder in anticipation. Still holding the whip, Laura leaned forward and removed one of the nipple clamps.

"Do you want me to loosen the ropes?" she asked. "Are these luscious beauties getting numb?"

She squeezed Karen's swollen breasts in both hands, watching Karen bite her lower lip.

Karen glowered at her, shaking her head. "Bite them. Please, Laura! I'm so close!"

"I want to lick them first," Laura teased, extended her wet tongue again and running it all over Karen's large, swollen black nipple.

Karen's body clenched, and she whimpered softly. "Ohhnnn!"

Laura took the delicious, popping nipple into her mouth and sucked it gently, not too hard, not risking too much, but bathing it in warm spittle and making Karen tremble and ache in desperate need. When Laura released it, Karen's nipple was stiffer than before, and wet and shiny.

Now Laura leaned back and brought the small leather pad on the end of the whip up to Karen's strangled breast, touching the wet nipple with it, watching Karen's eyes widen, hearing her breath accelerate. Laura tapped Karen's nipple three times lightly with the whip, just to threaten her.

"Oh god!" Karen gasped.

"You want it?" Laura whispered.

"Yes!"

"Only a little bit . . . to tantalize you," Laura smiled.

She raised the whip about three inches from Karen's breast, then snapped the excited, protruding nipple sharply with the whip's tip.

"Awwoonngg!" Karen moaned, wincing.

Laura snapped it again.

"Ohhgg! Oh shit!" Karen gasped, her eyes watering.

"You want the gag, honey?" Laura asked, concerned that they both would lose control, and that Karen would come any second in a wild, convulsive, shrieking paroxysm of ecstacy.

"Yes," Karen nodded rapidly. "Yes . . . now! Quick!"

Laura had done it so many time times that she could fasten it in place in under thirty seconds. Karen's eyes were streaked with terror and lust. Laura snapped the latch into place, then dropped her mouth again to Karen's beautiful big nipple, teasing it again with her tongue. She knew that the explosion was about to happen. There was no way Karen would survive more than a few strokes of the whip without coming.

While sucking and licking the bulbous, shiny nipple, Laura let the tip of the whip descend to Karen's blossoming wet pussylips, drawing the shaft up between the glistening vulva and letting the leather tip ride across Karen's swollen, excited clitoris. Karen stiffened, and her beautiful silky black flesh went into minor convulsions. She whimpered desperately.

"You know what's coming, you know what's coming, don't you," Laura chanted softly to her, still teasing her delectable wet nipple, sucking it, clamping it teasingly with her teeth.

She drew the whip, now wet with Karen's copious pussy juice, back up to the exposed nipple. Without warning, she snapped Karen's nipple hard with it, yanking the chain and sharply pulling the clamp on Karen's other nipple at the same instant.

"Awwnmngngg!" Karen groaned, tears wetting her cheeks as she body again stiffened in pain.

Distracted by the pain in her nipples, Karen did not notice the whip descending again, and Laura knew the moment was at hand. She had gained a split second of surprise, and she lifted the whip, bending her mouth to Karens' breast at the same moment, sucking the girl's big bulbous nipple in deep. Then she let the tip of the whip descend in three sharp blows onto Karen's exposed clit, sinking her teeth into Karen's nipple just as the first blow landed.

The third blow was actually superfluous since Karen was already coming in great torrents by the second one, her body convulsed in shattering spasms of ecstacy, clenching, coming, straining, arching, coming again. It was a moment that always drove Laura a little insane with lust herself.

She quickly dropped the whip, released Karen's tortured nipple, and slid down to push her mouth forcibly into Karen's streaming, throbbing pussy, eating and sucking her into a final, fierce climax, jabbing one finger up into Karen's ass to bring her to a killing finish. It was one of the most violent and prolonged orgasms Karen had ever had under Laura's hand, and both of them were shocked into silence by its force.

Laura untied and ungagged Karen, kissing and caressing her as if in pantomime, trying to heal the pain she had inflicted. Karen's eyes were still damp. Several minutes passed before she softly croaked, "Girl, you do know how to fuck."

"No. I know how to hurt you and make you come."

"Same thing. My body explodes when you touch it. Nobody else can do that to me."

"Mmmmm, I only do it to get paid back," Laura said, dangerously, nuzzling her neck, cupping Karen's breast and pinching her sorest nipple, the one she had bitten.

Karen winced. She quickly pushed Laura down on her back, kissing her savagely, squeezing one of Laura's breasts crunchingly in one hand at the same time, until Laura whimpered with pain.

"Don't hurt me too bad," she begged.

"Hurt is hurt," Karen whispered, menacingly.

She bunched up both of Laura's breasts in her hands and began sucking Laura's nipples hard, her lips tearing at them, her mouth trying to suck them off. Laura squirmed and moaned desperately under her. Each time they were together like this, the intensity hinged on each other's mood, and how rough and kinky they got depended on it. Karen was clearly in a dangerous mood. The way her mouth devoured Laura's nipples made Laura both frightened and excited.

It was like being sucked up into a hot whirlwind. Karen was as quick and skilled as Laura, and she had Laura tied to the bed in under a minute. Then she returned to Laura's aching breasts and tortured them some more, smiling when Laura cried out as she attached the nipple clamps.

"Owwncchh!" Laura winced, sucking in her breath, shutting her eyes in pain.

They pinched her tender nipples almost unendurably. She didn't know how she had been able to stand them before.

"Oh god . . . take them off, please!" she plead with Karen. "God, it hurts!"

Karen smiled. "I'll take one off," she teased.

She unclamped one of Laura's nipples. Then she again teased it with her tongue and lips, sucking it hard before releasing it, all shiny with spittle, erect and pointing. Laura's pussy was running with warm juice. But she shrank as she saw Karen raise the whip.

"Oh god . . . no," she gasped. "Please . . . no."

Karen was in a rough mood. The flying tip of the whip lashed into Laura's exposed nipple before she could even hold her breath.

"Auuwwonngg!" she howled as fiery pain shot through her breast.

Karen leaned forward and kissed her, even though Laura was gasping and moaning with pain, her cheeks wet with tears.

"I'm going to have to gag you now," Karen whispered. "You're already out of control."

"No," Laura shook her head. "I don't want to. Let me go. Please!"

But before she could put up even a futile struggle, the ball popped into her mouth, and Karen was fastening the small belt at the side of her cheek. And now Karen replaced the nipple clamp she had removed, further torturing the nipple she had just slashed with the whip, and began wrapping coils of rope around Laura's breasts, strangling them, making them swell and turn red. Laura's nipples, even with the clamps pinching them, swelled too.

When Laura's breasts were completely, tightly trussed, Karen ran the bristly rope back through Laura's asscrack, then up through her wet pussy, tying it to the chain between the nipple clamps. Laura could feel the rough bristles of the rope biting into the wet flesh of her pussy. And more, each time she moved, or even breathed, the rope moved in her pussy and yanked the chain, pulling at the clamps on her nipples.

She had never been in such a fix, and the pain and fear nearly made her pass out. Yet at the same time, her whole body throbbed, craving release, craving hot, mean, perverted sex that would make her come spectacularly. She knew it would happen, any minute.

She was totally helpless and vulnerable, and Karen descended on her body like a hot black tornado. Holding the rope and the chain, pulling them to torment Laura, she began to whip Laura's pussy lightly with the whip. Then she whipped it harder, harder, and pulled the rope-and-chain so sharply that howls of pain came from Laura's throat, muffled only by the gag. The whip bit into her pussy, crashed twice into her clit, then again, a sharp blow, another one, and she began to come and nearly faint at the same time.

Karen knew she had started to come and dropped the whip, pulling the fiendish rope instead, again and again, so that the bristly cord rubbed against Laura's clit, lacing her orgasm with pain, and pushing her into another one. And now Karen was there, as Laura had been, pulling rope out of Laura's tortured trench and replacing it with her mouth, sucking and tonguing Laura's pussy until Laura was coming a third time, her body clenching and shuddering through the ultimate climax.

But somehow behind the scorching orgasms she knew Karen wasn't going to stop there. She felt Karen's finger slipping up into her asshole, felt the rope strand slice up into her pussy again, and saw, through her slitted, tear-filled eyes, Karen swarm over her throttled breasts again, yanking the clamps, then removing them and mouth-fucking Laura's already-tortured nipples in a wild frenzy.

Laura came again in a sharp, painful convulsion, raped by Karen's finger and the harsh strand of rope that bit into her throbbing pussy. Dazed with shock, she hardly knew what was happening, though she dimly realized that Karen had turned wilder with lust than Laura had ever seen. She realized that her ankles and wrists were being untied; she was being turned over onto her stomach.

Her breasts, still tightly trussed and now reclamped with the ferocious nipple clamps, throbbed with pain. Karen quickly tied Laura's wrists behind her and shoved a pillow under her groin to elevate her pussy. Then she fished under Laura's bed for the four- pronged double dildo that Laura carelessly left there, in case she needed it.

And now it was a brutal rape pure and simple. Only a few times, by Gerald, and by Rob and his brother Eric, had Laura ever been sexually assaulted in such a thorough and brutal way. Karen slid the fat prongs of the dildo into both of them, and then reared up over Laura's upraised buns and fucked her like a cowboy riding a bronco.

The prongs speared Laura's asshole and pussy savagely, ripping into her in sharp, frenzied thrusts, while Karen went insane on top of her back, lunging forward, burying the rubber cocks deep in both of their bodies, grunting and moaning wildly. She reached under Laura's body and grabbed her already-tortured breasts, squeezing them mercilessly, pinching Laura's already-pinched nipples, and biting Laura's neck and shoulders as she fucked her crazily.

The torment was excruciating. She had never realized how strong Karen was. Even Brandi had never fucked her like this. And yet, through the punishment, she could feel a fresh torrent of coming envelop her. She and Karen both came, squealing and whinnying helplessly, their bodies vibrating and shuddering together in a perverse explosion of violent ecstacy.

Afterward, as Karen slowly disengaged herself, and untied Laura, both were stunned by the force of what had happened, Laura still shocked and dazed, her poor, tortured body still in pain, and Karen deeply ashamed of what she had done. Neither could speak. They had been welded together by pain and perversion before, but this was more than either had ever bargained for.

Finally, just being naked together in the same bed had its influence. They embraced gingerly, and Karen began silently to kiss Laura's wounded body, trying to make up for the damage she had inflicted. Long familiarity and deep affection slowly healed the trauma, but it was nearly half an hour before either one could trust herself to words.

"You really hurt me," Laura whispered haltingly.

"I . . . know. I got out of control. Fucking you made me crazy. I've never felt that way."

"My pussy is on fire."

"Let me lick it. I can make it better."

"No."

Karen looked away. "Okay."

Laura looked down at her breasts. Her nipples were red and raw, and big dark bruises had appeared on each creamy globe where Karen's fingers had bitten into her flesh. No man had ever used her as viciously as Karen just had. She didn't know what to feel. And yet, she had experienced a shockingly long and deep string of orgasms. She couldn't exactly pretend they hadn't happened.

Maybe this was what drove Karen to further and further limits of pain: the knowledge that she would come like that. Laura had felt hints of it, but never this deeply.

But she couldn't hold it against Karen. Finally, they kissed. Karen tried for their culminating, healing fuck, the one they always had before parting, but Laura could not manage it.

"I hurt too bad," she murmured, and Karen nodded.

"I'm sorry for what I did to you."

Laura smiled. "But I came hard. I came like you usually do."

"I did too," Karen nodded. "In fact, you could do me again, if you want to. I don't mind. You can get back at me."

"I don't have the strength. I want to take a bath. My nipples hurt."

Karen hung her head. But Laura kissed her and reassured her, and sent her on her way.
