Natural Selection -Part Four - by - The StoryMaster The pain of his initial penetration into her nether region was excruciating at first, but quickly tapered off to a less intense ache coupled with the sensation of absolute fullness. Then the big man began to get up a rhythm. Trinity had never been taken anally before, so everything would be new for her this morning. Her lover was quite large, and although he'd been considerate enough to lubricate himself prior to his intrusion into Trinity's anatomy, his presence none the less felt as if he were doing some rearranging of her abdominal organs. The fullness of his presence was of course augmented considerably by the fact that Trinity stood helplessly impaled on the vile vaginal mount apparatus or "Presentation Stand", as her Hosts called it. The mechanism consisted of a ten inch long, hard rubber phallus mounted atop a telescoping strut. The vertical strut was in turn attached to a heavy circular base. Near the perimeter of the base on opposite sides were two leather and velcro ankle restraint cuffs. Trinity's dainty feet and ankles were currently bound securely into these restraints, effectively spreading her legs quite widely. Her Hosts had then extended the telescoping vertical strut until the rubber penis entered her vagina. Then final adjustments were performed which caused the head of the hard phallus to become lodged deeply inside of Trinity. Thus immobilized, she was put out on display for the first time since her abduction. Being a very attractive young woman, Trinity had been quicky picked out by the large ogre who was presently enjoying the charms of her rear end. So it was that not only was Trinity being treated to her first anal encounter, but she was also experiencing the profusion of stimuli and the deep down satisfaction of having both of her passages filled simultaneously. At the moment, however, Trinity was anything but satisfied. For her, the entire morning had been an ordeal and a horror. First she was put on public display along with a couple of dozen other unfortunate young ladies. She and the other girls were then picked over like so much chopped liver by a group of the most unattractive buffoons that Trinity could ever have imagined. Most of the girls were quickly stripped of their plain blue "uniform" dresses then lead away to the many "Guest Rooms" which lined the perimeter of the main hall. Trinity's new friend, on the other hand, had decided that he wanted to have her publically. Never in her wildest dreams or darkest nightmares had Trinity ever imagined a scenario like the one she currently found herself in. She groaned miserably as the big oaf's cock plunged steadily in and out of her rectum, gradually increasing in both speed and force of delivery. Trinity sincerely believed that her humiliation and utter debasement could get no worse as she looked around the room. It was very difficult for her to maintain a rational train of thought for more than a few seconds, so consuming were her "friend's" attentions. But Trinity was able to recognize a half dozen other unfortunate young women still standing astride their mounts in the Great Hall. Some were alone for the moment, others were occupied. "Ohhhh!!!" Trinity gasped when her lover delivered to her a particularly forceful thrust, causing her to fall forward onto the balls of her feet. Most of her weight, however, bore down on top of the artificial penis, the head of which lay pressed against her cervix. Trinity winced in pain, shutting her eyes tightly. "Ugghhh.." she grunted in a most unladylike fashion when her new "friend's" hairy thighs slapped noisily against her firm buttocks. The head of his big penis pushed against the artificial member through the delicate internal tissues which divided Trinity's abdominal passageways, causing the beautiful young woman to shudder and moan. When Trinity next was cognizant of her surroundings she noticed right away that one young girl, a lovely brunette of perhaps fifteen years of age, was watching Trinity and her lover quite closely. Trinity felt her color rise in embarrassment. That is to say, fresh color in addition to that which already highlighted Trinity's neck, shoulders and chest, indicative of her unconsciously blossoming state of arousal. "Stop looking at me," Trinity plead silently with the young girl nearby. Her lover's penis pistoned relentlessly in and out, his big thighs now slapping regularly against her bottom. "Ohhhhh..." Trinity moaned, helplessly. The man had definitely gotten down to business. His tempo was now driving and regular. Suddenly, he released her bound wrists, wrapped one big bear-like arm around her chest, crushing her tender breasts beneath his forearm and pulled Trinity to a more upright position. His cadence increased. To Trinity he felt like an upside down pile driver as he rammed himself repeatedly into her quivering interior. The force of his delivery now caused Trinity to rise up onto her tiptoes with each stroke of his hips. When she came back down, of course, she was treated to an additional jab from her mount. His other forearm snaked around Trinity's body. "That's my darlin," the big troll murmured breathlessly from just behind Trinity's right ear. "I'm gonna cum in ya now, baby. Yeah." The frequency of his thrusts redoubled. Trinity thought that she was going to pass out from the hammering pressure in her belly. It was nothing like anything she'd ever experienced before. "I'm gonna cum way up inside of that pretty ass of yours, sweetheart." "Rrrrruuuhhh.. Uhh.. Uhh. Uhh. Uhh," Trinity groaned rhythmically. "Gonna leave you a little DNA sample in there, darlin'. So's you can always remember me. How's that sound? Yeah, baby." Two or three minutes that seemed like weeks passed while the big man pummeled Trinity internally. Then abruptly, he stopped. He'd been on the egress, thus Trinity's blue eyes widened in time to his final slow penetration deep into her interior. She could feel him begin to tremble, inside and out. "Here it comes, darlin. Gonna make you all warm inside," he croaked. Trinity couldn't remember the last time a man had actually ejaculated inside of her. She almost never failed to anticipate them and kick them off of her, before they managed to deposit their vile fluids into her body. Trinity took birth control measures, so she wasn't worried about becoming impregnated by the beast. It was the simple fact that he was about to inject a quantity of his disgusting maleness into her person, and into a part of her that she'd never be able to forget. Suddenly he clutched her so hard that Trinity couldn't draw a breath. She felt him tremble violently for a second, and then become still. At first she thought maybe it was a false alarm, but then Trinity heard the big man utter a gurgling moan. His first salvo caught her by surprise. Trinity wasn't certain what to expect, but what she did feel was something similar to a hot finger, pushing even deeper into her. It made her blink. If only Trinity could have seen the stupid expression on her face. Then the realization hit at the same time as her lover's second offering. The man groaned like a sea sick walrus as he hugged Trinity's small body to his, lifting her up on her mount and stretching her legs almost painfully in the process. With her lover's second wave of ejaculate came a growing internal pressure and a strange but not altogether unpleasant warmth. So deeply was the man's penis embedded inside of Trinity that the young girl would later recall thinking she felt him grate against her lumbar vertebrae. Her strong, previously unassaulted anal sphincter muscles reflexively clamped tightly around her lover's fleshy log, effectively plugging Trinity up and removing any path by which the pressure resulting from of her insemination might be expelled. Hence, while the young blond stood helplessly in the embrace of her new friend, the warmth spread upward and inward. Trinity in many ways received what amounted to a deep semen enema that morning. Traces of the horrible man would inhabit the darkest reaches of Trinity's colon and even her large intestine for long afterward. Powerless to prevent him from doing so, the dreadfully unappealing man became as much a part of Trinity as any man ever had and perhaps ever would, more so in fact. Standing by while her lover gradually softened inside of her, Trinity again noticed the young brunette watching her. Trinity rightly assumed that the girl had observed the entire affair from the comforts of her own display mount only a few feet distant. The fact that her rape in its entirety had been witnessed by another was deeply disturbing to Trinity. Being sampled sexually against her will and in public was something so soulfully debasing to Trinity that she would likely never fully recover from the incident. A significant "chink" in the head strong woman's "armor" fell away that morning as her lover's flaccid penis slipped from her rear end. Continued in Part Five... SM
