Chapter 5

The next day was a busy one. There were maps to decipher, equipment to set up. And Dr. Brewster had found the flat area between two hills where he suspected there might be the remains of an old pueblo. There was an expectant excitement in the air as the corner of a ruined building was exposed. Mona and Les helped mark down the exact spot every piece of broken pottery was found and Susan catalogued the fragments making them for later study.

But though the mood was strictly scientific, Susan's mind kept straying to sex. Whenever she saw Betty Brewster, she could only think of Nate's big cock sliding into her hole. And her thoughts of Mona were pretty vivid too.

When Susan returned her to her tent the night before, Mona had still been gone. Since she knew it didn't take a girl that long to pee, Susan could only assume that her tentmate had found Les sleeping in the trees and climbed into his bag for a little moonlight humping. Once again it-was Susan who felt like the maladjusted one. She was a virgin and with virtually no experience of sexual matters. Everybody else in camp seemed to be going at it like beavers!

What made it worse was that before she could bring pleasure to herself, Mona had returned to the tent, a satisfied look on her face. Susan had been too shy to attempt masturbation in the warm muskiness of her sleeping bag. Because she knew how wildly she always squirmed when she was reaching a climax. And she didn't want Mona to know that she did such carnal things.

It was just after the noon meal when Dr. Brewster shouted that he'd found the main kiva. A kiva, Susan had learned, was- an underground chamber used by the Indians for religious purposes among other things. The one Nate had discovered seemed to be in surprisingly good condition, the roof beams intact and the inner walls as yet uncrumbled. But the opening was narrow and since he didn't want to risk damage to the structure he called for Susan to join him where he was peering down into the ancient room.

"I don't know how sturdy these beams are," he told her. "Maybe the dryness has preserved them. Why don't I lower you down on a rope and you can check out the interior before we risk more weight on the ladder.

The ladder was pretty rotten. Two rungs gave under Susan's weight as she descended but Nate held up on the rope and kept her from falling. Since the rope was wrapped between her legs though it gave her a hot thrill every time her weight made it saw upwards between her cuntlips. Even through her jeans she could feel the pressure and the rubbing until she was breathing hard. Then her feet were on the floor of the kiva and she turned on her flashlight.

While Nate went to get a camera, Susan studied the strange paintings on the walls of the circular room. The rubbing of the rope had gotten her to shaking. Even though she was in the middle of an exciting discovery, her excitement drifted to things more akin to sex. She sneaked a hand down in her jeans. Who would know? The darkness wrapped around her like a comfortable blanket. She was digging under her panties now, finding the warm, damp slit between her furred lips.

"Ohhh," she sighed, touching her clit gingerly. As the nub throbbed with fresh blood and lifted from its slickened hood, Susan realized how badly she needed the release of a climax. Instead of draining off her sex energies, Les' mouth had only fired her up for more. And watching Dr. Brewster play with his wife hadn't helped any.

"Now, it's my turn, darn it."

Dr. Brewster lowered a camera through the opening and announced that he was going back to camp for more equipment. That was just fine with Susan. It was at least a thirty minute trip to and from their camp. That would give her time to really give herself a going over. When Nate's shadow had moved away from the hole, Susan stripped her jeans down and then her panties. She sat in the sand in the middle of the gloomy enclosure and peered down at her overheated lips.

Her cunt was a swollen, throbbing flower of fevered flesh. It glistened as she teased the bead of her cut up and out from its hood and then pinched it gently between thumb and finger. The sand was spotted with her juices as she flicked and gouged at her tender crevice.

"Uhhhhnnnn, I needed this so bad!"

But it wasn't as much fun with her jeans tangled around her knees. And who would know if she took them- all the way off? She had plenty of time after all. Susan took off her boots, socks and then her jeans and panties. She hesitated about taking off her shirt but shrugged and threw it down too.

The nakedness of her body in that dark, mysterious room was keenly pleasurable. For the first time she noticed the rock near the center of the kiva. It was a rectangular block about as long as she was tall. Its polished surface seemed almost made for her to lie down on. So Susan did lie down, drawing her heels back against her bottom and throwing her knees wide. Now her finger felt that much better as she caressed herself.

"Mmhhuuuhh," she groaned, pumping her narrow hips slowly. She still had almost half an hour so she didn't want to hurry. She wanted to really enjoy this, to drain the sexual energy from her body and be at peace at last.

The slurping of her finger moving between the plump, firm lips of her vulva excited her as much as the friction. She worked her ass around on the smooth, cool stone.

The soles of her feet burned and it was hard for Susan to resist hurrying her body towards a breathless climax. But she meant to enjoy this for as long as she could. A shadow passed across the opening in the kiva's roof and she saw Les trying to peer into the gloom.

"Damn," she cursed, trying to find her panties. She managed to get the skimpy things on and was feeling for her jeans when Les began to descend. It did her no good to cower behind the big block of stone she'd been lying on. Les brought his flashlight around and the beam shined across her naked shoulders.

"So, having some fun and games while the good doctor was getting equipment, huh?" He seemed amused. And excited.

"Les, if you'd be so kind to turn off that damned light and let me put my clothes on."

"Maybe I don't want to let you put your clothes on." He came at her then, pulling her up by the wrists. As he stared at her naked belly and the damp crotch of her panties, Susan could see the lust in his eyes. He touched one of her small breasts and shook his head slowly.

"They're as pretty as your cunt."

"Les!"

But he moved so quickly that Susan didn't know what was happening. She was suddenly bent forward over the stone dais as Les' flashlight dropped into the sand. He jerked her panties down just far enough to expose the cheeks of her ass.

"Oh, God, nooo!" she shrieked. She heard him squeezing the sun-tan lotion. The greasy stuff went down her crack and Les used his thumb to smear it over her rectum. Though she was shocked by his crude behavior, Susan felt an unexpected thrill too. Just touching her ass, Les had made her nipples swell and her clit throb.

"I've imagined what it would be like to stick my cock in this sweet little ass of yours," he panted, biting her back hungrily. "And to see you squirming turns me on even more!"

"Les, you can't! You just can't!"

"Who'll ever know. You sure aren't going to run to Dr. Brewster and tell him what I'm about to do, or will you?"

"Ohhh, God!"

"Feel •this?" Les growled. Susan did feel something. It was too big for a finger. And it was too hot for anything but.

"Don't!" she cried again.

"Christ, you're hot right there ...

"Oh, Les, this is awful!" Susan blushed from shame and disgust. The thing Les was trying to do was so taboo that no one even talked about it much. But the smoothly rounded tip of his cock felt so strange. He rubbed against the greasy knot of her rectum. Susan squeezed down harder, determined to keep him from having what he seemed to want so badly.

"Come on, relax." Les kissed the nape of her neck. "It'll hurt if you don't loosen up."

"Ohhhh, stop it! Stop this awful behavior right now!"

Les bit the back of her neck. He didn't hurt her but the sensation of his sharp teeth squeezing her like that made Susan whimper and for an instant, her sphincter relaxed. Les was ready. She felt the thickness of his tip sliding into her muscled opening. She tried to squeeze back tight again but though his barb hadn't penetrated her completely she couldn't force it back out either. A hot thrill went up through her belly and she groaned and bit her lip.

"Oh, damn you! This is awful! It's horrible!"

"And you love it," Les hissed. "You're the kind that always likes a little abuse. You like to be degraded."

"I hate you!" Susan cried. But with all her squirming around she felt more of Les' thick cocktip opening her. The cheeks of her ass seemed to squeeze his shaft and more tremors of excitement went up the insides of her thighs.

When Les lunged suddenly, stabbing his glans just inside her taut rectum, Susan flopped like a fish on a harpoon. It felt wrong and wicked and ugly and to have a man's cock going up her ass! But other emotions swept through her at the same time. Her breasts rubbed against the smooth stone, her belly heaved against it too. Les clutched at her willowy body in a savage way that heightened her awareness of the dark kiva surrounding them. Susan couldn't smother the pleasure inside her. It was a weird primal pleasure. The pleasure of being forced, taken against her will. Of her panties dangling around her knees, then slipping down to her ankles.

But more than anything it was the hot rub of that cock inside her rectum. Her young ass squeezed and pulled at the thing and as Les forced deeper into her guts, she groaned in a low, rhythmic way.

"Uhh, uhhhh, uhhhhh, God ... Ohhh, Les, please don't do it anymore!"

"Feel too good?" he laughed. "Afraid you're gonna come with my cock up your ass?"

Even Les' crudeness excited Susan rather than turned her off. Maybe she was afraid of coming like this. Maybe she was all fucked up. But words made no sense. When she tried to get hold of them they skittered away leaving that thick hot penis in between the white cheeks of her ass. It felt so ... so sexy!

"No! I don't want to feel this!"

"Oh, Susy baby, your ass is beautiful! It's the hottest, tightest little thing I've ever dipped my cock into."

Susan realized that her imagination was working overtime. She was really wondering if getting fucked in the cunt was anything like getting it in the ass. The feeling of something hard and long being forced inside her body was so intense, so incredibly different than anything she'd experienced before. Les held her squirming hips with both hands and lunged again. The squishy sound of the sun-tan lotion made Susan think of how it had sounded when Dr. Brewster fucked his wife. But he hadn't fucked her in the ass. It seemed that Les was out to degrade and shame her.

"Don't you feel that going in?" he growled, trembling as her hot bottom squeezed down around the base of his penis.

"Yes ... and it feels awful." It was a lie. As ashamed and embarrassed as she was, Susan felt the tingling thrills that burned along her dripping cunt. The in-and-out tension was pulling the flesh around her clit. Every time Les entered her deeper, her clitoris was stretched out of its hood.

And now he was getting very excited, pumping faster, grabbing her hipbones so hard it hurt.

"Ohhh, ohhhhh, Les, please, stop now. I feel ... feel so funny."

"I couldn't stop if this damned kiva was on fire," Les gasped. His cock felt bigger than it had before. When he pulled back and just the head stuck inside her body, Susan pinched down her ass muscles as hard as she possibly could. There was a choking sound behind her as Les writhed and trembled. His prick was stuck inside her ass. He realized just how strong her rectum was now and in panic was trying to extricate himself from the feverish trap. But even the slickness of the lotion wasn't enough. He jerked harder and the jerks only succeeded in exciting Susan's cunt.

"Uhhhhhh," she gasped, unable to relax her ass now that she was pinching down around that rod of blood-hardened flesh that Les had stabbed into her. She bucked her hips up and down and heard him groan. The tingles around her clit built stronger.

"Jesus Christ," Les moaned, clutching wildly at her plump ass cheeks as if he was searching for a way to open her spasming muscles. Then, with an agonizing lunge, he shoved his penis into her ass to the hilt. The slide of that thick, throbbing meat made Susan's back arch sharply, bringing her small tits off the big stone. Sliding a hand against the soft swells, Les held her up like that while he hunched wildly into her slim ass. She was squirming uncontrollably while he penetrated her again and again. Then Susan knew why she was squirming like that. She was coming!

"Uhhh, uhhhhhhh, God!" she whimpered, drool leaking down her chin.

"Baby ... ohhh, baby," Les babbled, each lunge sending a shock wave of pleasure through her ass and cunt and tummy. The glow spread in surging waves of ecstasy. Her nipples were thick, darkened stalks under Les' hot palms. He cupped and squeezed the tender flesh as he rode her like a cowboy on a wild mare. His penis felt so hot! So sharp!

Susan flopped helplessly, her toes pointed in the sand at the base of the big stone. Cum was leaking down the inside of one leg. She could feel the slimy mess between the feverish cheeks of her ass. In and out, in and out, it never seemed to stop! Her clit felt like a white hot bead of steel. She let out a breath and writhed more violently in the clutch of Les' hungry hands.

And though she felt sullied by the way he'd taken her, Susan also felt a burning thrill. Just knowing that her clasping hot ass was causing his cum to spurt had a strange effect on her emotions. It made her feel the feminine strength that'd been latent during her adolescent years. She realized that a female was necessary for the kind of pleasure Les was experiencing right now. And that a male had that incredibly stiff thing that was rubbing her guts and making her cut pulse with maddening thrills.

Les sagged finally, his cock still throbbing but slower, weaker. Without being able to control her body's convulsions, Susan still twisted around on the smooth stone while her throes died away. Then, with the hot joy of the moment gone, she was painfully aware of her position, of her cummy, greasy bottom. She was shamefully aware too of the fact that she'd been sodomized against her will.

"Ohhh, pull it out! Please, take it out of me!"

Les' cock came out with a popping sound as her muscles seemed to grab onto his flared tip until the last moment. Susan couldn't bear to look at him. She grabbed her clothes and made it up the rotting ladder somehow. She felt dirty and awful. She ran in the direction of the river Betty Brewster had scouted upon their arrival at the camp. She knew it was to the south somewhere so she ran heedlessly through the scrub trees and bushes, tears running down her cheeks.

"Damn him," she mumbled, hurrying towards the sound of running water now. When she got to the shore she plunged right in clothes and all. The water came quickly to her waist and she let the chill take her breath. It was punishment for what had happened. Punishment for the enjoyment she'd gotten from having her ass fucked.

The mountain stream quickly washed away the signs that she had been abused. Only the sting of her feet made her realize that she'd run through the woods barefooted. When she dragged herself onto a rock near the middle of the stream she found her soles bleeding. Her shirt was plastered to her breasts and belly and her jeans were heavy with the water they'd soaked up.

Susan had just peeled her pants when she sensed someone coming through the trees. It was Dr. Brewster and she felt her face flush hot and red.

"Susan, are you alright?"

"I cut my feet."

"What were you doing running through the forest barefooted?" Nate was taking off his boots now. She tried to turn so he wouldn't see her soaked panties and the way they clung to her pubes. The sheer nylon was almost transparent now that it was wet. Her brown thatch of cunt hair was clearly visible. And each breast was outlined under her shirt, the nipples dark and tumid from the chilled water. Dr. Brewster waded into the river and splashed towards the rock where she'd found refuge.

"Les said that you got spooked in the kiva and suddenly ran out."

"Yes. I guess I did." Susan blushed again. She couldn't ever tell her favorite professor what had really happened. He was close now, climbing up onto the rock. Susan shivered. There was no way she could hide her near-nakedness. Nate Brewster looked at her but quickly turned his attention to her feet.

"I'll have to carry you back," he said. "It's going to be tender walking for awhile with the cuts you got."

"My clothes are soaked," Susan whined, stating the obvious. She didn't want to go anywhere. She just wanted to stay on that big rock and be left alone. But suddenly she was crying, surrounded by her professor's strong arms. He was so fatherly, so good. She sobbed uncontrollably, her cheek against his chest as he smoothed her back. His hands felt so good! She was safe now. Safe forever.

Dr. Brewster tossed her jeans over his arm and slipped into the rushing water. Susan let herself slide into his arms, clasping her hands behind his neck as he held her under her ass and started across towards the shore.

Now she felt the slide of her near-naked pubes against his body and the mash of her soft breasts on his chest. She shivered, the old lusts Les had started coming back again. She scolded herself, knowing it was a perverseness to feel anything like that for Dr. Brewster. He was trying to help her, trying to protect her in a fatherly way. But by the time they struggled up onto the shore, her cunt was becoming slick and she tingled all over. It wasn't just because of the chilly water.

With a shock she noticed that Nate's clinging pants revealed that his cock was not in its normal state either. It was erect! It was pushing his khaki pants out in a big lump in front.

The moment was electric. Susan knew that Dr. Brewster had seen her staring at his crotch. But instead of lowering her eyes and blushing she felt his own eyes pulling her. She looked up. He was smiling down in a way that frightened her. It wasn't an evil smile but there was more to it than just fatherly affection.

"I think it's time now for me to tell you a few things," Nate said.

"Beg pardon?" Susan said, swallowing nervously. Dr. Brewster helped her stand. Her feet hurt when she put weight on them. Suddenly she saw the leather thongs in his hand. "What's happening?" she cried, backing away. Dr. Brewster came after her. Susan started to run but the pain of her wounded soles against the rocks along the shore made her cry out. She was limping helplessly when Nate's strong arm went around her waist. He turned her gently and pulled her arms behind her.

"I don't understand, Dr. Brewster. What are you ... "

"I'm tying your wrists behind you, Susan. If it's too tight, I'll loosen them."

Susan's mind swirled. She felt dizzy and weak. Like she'd stepped onto a strange planet in another galaxy. But the strangeness had a way of exciting her too. A way she didn't come close to understanding. To have her arms bound behind her made her feel so helpless. And that's what Nate Brewster wanted her to feel, she thought.

He picked her up and carried her into a thicket of trees. They went on until he'd come to a small opening in the bushes and gently put her down. His strong hands caressed her shoulders and her neck. She was shaking like a leaf. Standing there before him she realized how big he was and how thin and soft she was. He seemed like some god looming over her.

"I've waited for years for this moment," he said, voice husky. "For this moment and what will soon follow." Her eyes fluttered as she tried to understand what he meant. She tugged at the thongs that held her wrists tightly together. Chills of excitement went through her body and her cheeks reddened. Nate saw the flush of pink.

"Yes, that's the way I want you to feel."

"I don't know how I'm supposed to feel," she whimpered.

"Like a virgin princess," he whispered. Then he unbuttoned her wet shirt and peeled it back off her shoulders. Susan knew she must be having a crazy dream. She would awaken soon and find herself in her own tent. But she didn't wake up. She wasn't dreaming. Nate Brewster's fingers trembled slightly as he caressed her small, firm tits. She was breathing like a scared rabbit. But she panted even harder when she saw Dr. Brewster undo his belt and open his pants. He was undressing! Right there in front of her!

"Dr. Brewster!" she gasped, eyes wide with fear. Another wave of tingles swept over her skin as she saw his cock swing up, the blue tip glistening from its foreskin sheath. One knee trembled and gave, then the other. Whimpering pitifully, Susan sank to her knees in the sand.
