Tyrannosaurus Sex
It was early afternoon and a female tyrannosaur had found shade to avoid the heat of the sun, her eyes closed as a gentle breeze wafted over her bulk. She had been having difficulty settling over the past few days, having recently come into her receptive cycle. While in her late forties she was by no means near the end of her life though her successful reproductive years were long over and males of her species tended to be interested in younger, more fecund partners. She had been feeling decidedly alone until suddenly her head snapped to attention and she rose to her feet, growling as she sniffed at the air. One of her kind was approaching, a fact soon verified as a relatively young male stumbled through the forest clutter. He too was tasting the air with his nostrils and her pheromones had undoubtedly caught his attention. The young buck had only just reached maturity and judging by the recently healed wounds on the side of his head and neck, he had been driven this far into the forest by the larger territorial bulls. The two dinosaurs approached each other and the male was careful to keep his snout lowered in a nonaggressive gesture. Small males were occasionally maimed or killed by the physically larger and more powerful females so his apprehension was well justified. The stocky female casually stared at the cautious young intruder before turning away and walking to a nearby grassy clearing. Standing still, she faced him and lifted her head to expose her vulnerable throat, trilling softly to signal her placid mood. Satisfied that there was no danger the male approached, sniffing at the air as her pheromones began to excite him.
The two dinosaurs slowly circled each other in a typical greeting ceremony and the female gazed longingly at the alluring bulge of his cloaca before both partners maneuvered so that they stood face to face. Tyrannosaur courtship behaviour tended to be rather brief and, eager to have the young bull inside her, she was in no mood to draw out the affair any longer than necessary. Their muzzles touched and the two animals gently rubbed their snouts together, the rasping sound of their scutes scraping together serving to stimulate them further. The carnivores then proceeded to nuzzle down and along each other's necks and flanks until their heads were oriented towards the other's tailbase. Growling quietly, the female lifted her tail slightly to allow the young buck to investigate her genital area. He tentatively nosed under her tail, nostrils flaring in response to her mating pheromones as his ridged muzzle gently brushed over the external folds of her cloaca. She closed her eyes for a few moments, relishing a sensation she had not enjoyed for too long a time, hissing with pleasure as the male eagerly explored her vent. After a few moments the female turned her attention to the bulge situated at the base of her partner's tail, attentively nuzzling the sensitive area around his cloaca to which he growled contentedly.
Both tyrannosaurs chirruped and hissed softly as they investigated each other's genital area though after about a minute of the intense mutual stimulation the male's penile retractor muscles instinctively responded to his heightened state of sexual arousal. Grunting excitedly, the female's eyes widened as she watched the slit under his tail expand and spread apart as his intromittent organ slid out into the light of day, her young partner gasping with surprise at his first erection. It had been a long time since she had last seen a male tyrannosaur's exposed genitalia and the sight excited her considerably as anticipation of what was to come raced through her mind. Fully everted the penis measured almost a meter in length with a distinctive upwards curve and a thick base that gradually tapered off to a slender, rounded tip. Her massive head darted forward and she tenderly bumped her snout against the hard fleshy appendage, playfully nuzzling the shaft. The young male hissed and trilled contentedly at the sensation, his interest in the underside of her tail now moot. The old female spent a few moments intently examining the erect penis much to the male's delight until, her curiousity satisfied and her body fully primed for sex, she decided to initiate copulation. Turning her back to him she placed one leg slightly in front of the other to brace herself against his imminent weight. She leaned forward to elevate her hindquarters then enticeingly moved her thick tail off to one side, exposing her cloaca. It was the novice buck's first mating and he looked over the imposing bulk of his intended partner, a little intimidated though his instincts soon came into play.
Briefly draping his chin over her for leverage, he mounted from behind and to the other side of her swept tail, supporting himself with his two tiny forelimbs on her hips and she obligingly crouched down so the smaller male could more easily cover her. He grunted as he carefully stretched his right leg over her tailbase so that the limb hung off the ground before pushing his tail underneath hers to yield closer conjunction of their reproductive organs. Maintaining his precarious balance he began to carefully maneuvere his hips, guiding his long intromittent organ underneath her tail so that the curved shaft skidded across his partner's smooth ventral scales. The sensation of his penis touching her body excited the female greatly, though she took care to remain motionless as he continued in his search for her cloaca, not wanting to distract the already nervous young buck. His initial attempts at insertion were awkward and for half a minute he randomly probed her afterbelly, unable to reach his objective as the inexperienced bull had mounted with their genitals slightly out of alignment. He snorted in frustration and his older partner, more familiar with the mechanics of copulation, discreetly shifted her hindquarters so that his extremity was in closer proximity to her eagerly waiting vent.
The female's increasingly excited vocalisations told the young bull he was nearing his target and he was soon hissing with anticipation as he felt the end of his penis prod and rub against her genital area. She growled at the sensation, one she had not enjoyed in a long time and as his member gently nudged her cloaca she responded by relaxing the muscles that would allow entry to her body. The aroused female desperately wanted the penis inside her and suddenly, for one glorious, perfect moment, she sensed the tip briefly poke into the concave folds of her genital slit though unfortunately it slipped out as the overly roused bull almost lost his place. Undeterred, he continued to search until the end of his curved shaft once again pressed against the shallow groove under her tailbase. The bull then carefully pushed and his partner hissed with satisfaction as she felt the tip slowly work its way past her external genital folds. Finally the first few centimeters of his phallus slipped inside her, gradually spreading apart the outer lips of her cloaca as he entered the opening. For the young bull the insertion yielded unprecedented sensations and he groaned happily as he sensed her warmth engulf his member. With a loud grunt and a sudden forward movement of his hips, the male pushed about a third of his shaft into her upon which she lifted her head and with a thunderous roar announced her approval.
The female shivered as the penis slid up into her cloaca, its tapered girth spreading apart the fleshy, muscular passage and causing her lower reproductive tract to reflexively tighten then relax a few times. The young bull grunted excitedly and cried out as he felt her cloaca grip his sex organ though he soon calmed down and positioned himself comfortably behind his partner whereupon his instincts came to the fore. He began to move back as if he were going to withdraw, though before his penis slipped out he pushed it back inside to more or less its original location. He growled with surprise and proceeded to repeat the behaviour, carefully moving his pelvis as he straddled her larger frame, the slow rhythmic motion causing his genitalia to slide back and forth inside her. For the youngster, his first coupling was yielding unprecendented pleasures and the sensation of her tight, moist flesh gently stroking up and down his shaft was unlike any other he had known. The initial insertion of his penis had been a slow and gentle affair and his ensuing pelvic thrusts were no different; indeed, a casual observer would have been amazed at how remarkably tender the gigantic predators were during sex. The young bull carefully moved his hips as he explored the tight passageway that surrounded and massaged his member, though each time he pulled back from a thrust the cool ambient air that wafted over his shaft was in stark contrast to the inviting warmth of his partner's genitals.
The female groaned happily as his penis slowly pulsed inside her and she savoured the sensation of her cloacal cavity stretching out each time he pushed inside to be followed by a strangely vacant feeling when he pulled back. She was careful to keep her genital tract relaxed during this initial stage of their union, her way of allowing the youngster to become accustomed to the rhythmic motions of mating. The young male grew more confident and after about a minute of improvised thrusting he moved slowly so that between one quarter and one third of the length of his penis slid back and forth inside her, holding still for a brief moment at the peak of each thrust. The shallow depression of the female's concave genital opening would spread out as the tapered shaft went in, only to contract and bulge out a little during each backthrust. While his first sexual encounter was yielding unimagined elation his older partner, having been rarely mounted over her past few heat cycles, was being suddenly reacquainted with a very intimate pleasure. The female tyrannosaur began to cry out as she felt his smooth shaft repeatedly stroke the engorged clitoral ridge situated not far from her entrance, the alternating pressure and friction making her shiver slightly. Eyes half closed and softly hissing, she savored every moment that the firm appendage was attentively pumped into her, acutely aware of every minute movement of the male's hips.
The young male had been mating with his older partner for a little over a minute when his steady thrusts began to stimulate the muscles that ringed her reproductive tract. He felt her genitals tighten each time he pushed his phallus into her then relax as he pulled back, the contractions matching the rhythmic movements of his pelvis. The pulsing sensation excited both dinosaurs considerably and as the male eagerly worked his hips, enjoying the sudden tight resistance, their roars echoed throughout the forest. The female grunted contentedly and though their union was proving immensely satisfying, after a minute or so she wanted him to penetrate further into her cloaca which was both ready and capable of receiving a great deal more of his member. She encouraged him to do so by abruptly pushing her hips back at the exact moment he thrusted, the motion acting to work a little more of his tapered flesh into her. The male quickly realised what she wanted him to do and responded by ceasing his thrusts just long enough to clasp her hips with his tiny yet powerful forelimbs and reposition himself behind her. The female could feel his weight bearing down on her as the bull pulled himself a bit further up her back, bringing their bodies closer together while pushing his penis deeper into her vent. After several such joint motions he stood still for a few moments and hissed, a little over three quarters of his member firmly inside her. Pleased with the depth of his penetration, she stood still and allowed her partner to reassume the active role.
The male continued his slow, gentle thrusting, growling with satisfaction as her tightly stretched passageway stroked his penis. He pumped deep, moving his hips so that only a few centimeters of his long shaft could actually be seen sliding in and out. For his partner, the passion of their union was unlike anything she had experienced before and she hissed with pleasure at the pressure and friction the thick shaft was applying to both her genitals and clitoral ridge. He had only been inside her for a little over a minute since repositioning but never before could she recall a mating so attentive, thrusts so purposeful or a penis so firm. She swung around her massive head to look up at him and as their eyes met no spoken language was necessary to convey the mutual pleasure of their intercourse. Even though the old female was beyond her fecund years, theirs was no cold mechanical act to simply fertilise eggs. The sole objective of their union was sharing in the simple joy of sex and the two tyrannosaurs were making love in every sense of the phrase. They trilled and chirrupped happily for the few moments spent gazing at each other and all the while the male continued to enjoy his partner's cloaca, discovering and noting a few sensitive points that seemed to give her particular pleasure. Soon she returned to looking straight ahead, snout dipped slightly and eyes closed, her mind focused on the steady pulsing inside her.
The two dinosaurs coupled in this manner for a couple of minutes, the young male staring blankly at the back of her massive head as again and again he pushed his penis as far inside her body as he could, each thrust coming slightly faster than the last. Their resulting hisses and grunts came increasingly in unison as their genitals worked together to create an intoxicating sexual bliss. The female relished every second of the deep, repetitive pumping but knew from experience that her young partner wasn't going to last much longer and she was determined to have him breed her for as long as possible. The pace of his pelvic thrusts continued to build and after a few moments he no longer took the time to briefly pause at the height of each push. Sensing he was close to climaxing, she waited until he pulled back then abruptly tightened the muscular cavity that enveloped his penis. The sudden resistance made him stop and the male stood still, a little confused and unsure how to respond to the unexpected situation. Trilling reassuringly, the female waited a few moments before gradually relaxing her tight passageway just long enough to move her pelvis towards him then away, in one movement very slowly sliding a few centimeters of her cloaca up then down his shaft before standing motionless. Her head swung around just long enough to glance up at her somewhat bewildered mate and emit a low grunt as she repeated the movement and once more her warm, moist genital flesh stroked along his shaft in one gentle motion.
The male seemed to understand that she meant to prolong their mating and stood motionless for a brief time, his urge to climax subsiding as he focused on staring at a certain point at the back of her head. After about a minute the young bull resumed his pelvic thrusting, though he withdrew his penis to its original depth of penetration so that between one half and two thirds of the shaft slid in and out, as before pausing momentarily at the height of each thrust. He could feel his partner's genital tract tighten and relax in rhythm and he growled contentedly in response to the slow, methodical pulsing. The female's vent collapsed inwards as he pushed, the shaft pulling the outer lips of her cloaca down into her body and when he pulled back the folds resurfaced, stretching out from her slit wrapped around his member. She hissed and shivered as his tapered phallus massaged her clitoral ridge, her cloacal cavity expanding and contracting to the change in girth as he moved in and out. Tyrannosaur mating rarely lasted more than two minutes, though the female's initiative was yielding intromission of a duration she had never before experienced. She lifted her snout submissively as she relished every second of their union, savored every movement of his hips, treasured every centimeter of the penis inside her.
The two dinosaurs tenderly made love; the male attentively nuzzling the female's neck as his foreclaws gently flexed in rhythm with his thrusts whilst the female chirruped contentedly, hissing and growling each time her young lover found a particularly sensitive spot. After a little over fifteen minutes of passionate sex, the bull bellowed excitedly and began to drive further into her genitals with every thrust, soon pumping with such force that her body gently rocked back and forth. The older female knew what was about to happen and, despite having mated numerous times in the past with more experienced bulls, she howled in response to the young male's unexpected prowess. Now seconds away from climax their heads bobbed in unison, matching his thrusts until the male pushed his penis inside her for the last time, penetrating as far as was physically possible at which point he ejaculated heavily and both dinosaurs raised their snouts, simultaneously releasing an ear splitting roar during which the male pushed against her a few more times, each reflexive movement releasing another stream of fluid though less than the one before. Chemicals in his semen triggered waves of contractions that rippled down the length of her reproductive tract, milking every last drop of the bull's sperm which quickly filled her oviducts. Once their orgasm subsided she turned to look at him whereupon they both stood still for a few moments, savouring the afterglow of their lovemaking. Once satisfied that the mating was complete she lowered her hindquarters and the male climbed off her back, excess seminal fluid dribbling from her genital folds as his spent penis slid out and retracted into his cloaca.
Normally a female would drive a male away after mating but instead she lay quietly on her belly and stared at the adolescent bull who was clearly exhausted from the physical demands of their union. He sat back on his haunches not far from her and she could hear his laboured breathing, each breath coming more slowly than the last. After about half an hour the female became restless as her sex drive returned to the fore and she decided to initiate another mating. The old female grunted as she rose from her prone position and approached the male, rubbing her head against his flanks before proceeding to his tailbase. He quickly scrambled to his feet, hissing with excitement as he felt her snout touch his cloaca to which the young bull reciprocated by nosing around her genital opening, the outer folds of which were still swollen and moist with fluids from their previous union. The female watched her aroused partner's cloaca slowly spread apart to release his long, curved penis, its thick base in stark contrast to the narrow, rounded tip. She playfully nuzzled the hard, tapered shaft whilst the bull growled contentedly, the end of his own snout wet from eagerly exploring her vent. Once satisfied that the young male was ready for sex she walked in front of him to assume her pre-copulatory stance by crouching down and leaning forward with her tail arched to one side.
Eagerly accepting the invitation, the male mounted and clasped her hips with his tiny yet strong forearms. His penis soon located the outer folds of her cloaca upon which the bull pushed, roaring at the familiar sensation of warm flesh engulfing his member. The female hissed excitedly as she felt him enter then proceed to work his phallus up into her reproductive tract until about half the length was inserted, the tapered shaft tight against her engorged clitoris. Her slick passage had yielded an effortless penetration and the dinosaurs adjusted their posture until the penis was comfortably positioned inside the female. She lifted her snout to indicate her readiness to continue and as before the male began to move his hips, pulling back then pushing up into her, thrusting again and again as his older partner grunted encouragement. The gentle pumping stimulated her powerful cloacal muscles to tighten then relax, the rhythmic pulsing perfectly matching her partner's pelvic thrusts. The male nuzzled and nipped at his partner's neck whilst he attentively worked his hips, slowly sliding his penis in and out, his thick shaft stroking her clitoris while she would occasionally turn to gaze into his eyes. After about twenty minutes of such intimate lovemaking the female suddenly growled and began to push back, encouraging him to penetrate further. The bull pumped hard and deep, faster and faster, until both dinosaurs screamed as they climaxed together. The tableau would repeat over the following few days that she remained receptive and they would remain together, mating frequently.
