Date: Mon, 14 Feb 2005 20:43:29 -0000 From: Beverly Taff Subject: Dog Day Afternoon Chapter 17 Two by Two Chapter 5 The operation proved to be a fairly easy procedure. The only difficult part being the prior enlargement of Zac's scrotum to accommodate Steve's testicle. For about a month before the operation, Vicky inserted a special expander inside Zac's scrotum to enlarge the capacity. Zac had to be kept indoors for the whole month so they spread the word that he had picked up a bug and wasn't feeling well. This was partially true. Zac certainly wasn't feeling well. The expander caused some considerable pain for every day Vicky had to gently turn the screw to expand the frame. Zac had to wear a muzzle, vetinary collar and even a vetinary 'tutu', to prevent him worrying the torture instrument in his groin. Eventually, his month of torture ended and the transplant went ahead. Surgery can sometimes produce some unexpected complications. To Vicky's surprise, Steve had a dizzy turn during the operation and became groggy even though he had only received a local anaesthetic. He was confused and rambling towards the end of the procedure and Vicky was left to complete the transplant on her own. She took advantage of this hiccup and deftly transplanted both Steve's testicles into Zac's scrotum. Then she returned both Zac's testicles into Steve's scrotum without him knowing. She also performed a small modification about one third of the way up from the base of Steve's penis. Carefully, she inserted a canine 'knot gland' then grafted it subcutaneously after introducing it carefully along the penis from the scrotal sack. This left no visible scarring and therefore, no evidence of anything untoward. With all the other surgery and modification, Steve never noticed any difference because his whole genitalia was swollen and sore. The main pain was in his balls and that took his attention from all other irritations in his penile area. Both of Vicky's male companions were bed-ridden for a week but eventually; they started to move about the apartment. Because they shared the same pain, they were supportive and sympathetic to each other as they hobbled painfully around the apartment with their legs parted to avoid the swellings. All this surgery was performed during the summer vacation so few people noticed their absence and those that did, put it down to their being away on holiday. To reinforce this perception, the three of them slipped away for a fortnight to recuperate at leisure. When they finally returned, both of them were fully recovered. The only obvious sign of the surgery was Zac's slightly enlarged scrotum. Fortunately, Vicky had carefully transferred a largish flap of furry skin to the back of the expanded scrotum so Zac's genitalia were partially hidden. From the rear, Zac's scrotum appeared no different. It was only when you got a good look underneath that the enlarged scrotal sac was noticeable. Steve of course was not affected aesthetically at all. Zac's testicles were slightly smaller but they still filled Steve's scrotum and he deemed the new size and shape to be a perfectly normal consequence of the surgery. Steve had no idea that he now had both Zac's testicles nor had he any idea of what Vicky had done to his penis. When aroused, he got normal erections and ejaculated perfectly with a spectacular orgasm. One side effect was that his libido became more vigorous. When he started getting frequent erections, he became suspicious and finally challenged Vicky about it. "So what did you do to me?" He demanded. "I transplanted one of Zac's testicles into your scrotum." Replied Vicky only telling half the truth. "So his testosterone is coursing through my body." "Uuhm, - yes," confessed Vicky still only revealing half the truth. "So that's why I get horny all the time and have to relieve myself all the time by masturbating?" "Probably. I didn't think it would cause you to be that horny. D'you want me to remove it?" "I. - I'm not sure," replied Steve as he considered the pleasure he got from having such a vigorous libido, "I'll have to think about it." Vicky stared at him thoughtfully. "What d'you mean, 'think about it'?" "I'm not sure yet. I've noticed that Zac seems much more curious and affectionate towards me. Perhaps his nose is telling him something." As if to reinforce Steve's remark, right on cue, Zac buried his nose in Steve's crotch and sniffed inquisitively as he whined. "There. See!" Observed Steve. "Look. He's at it again. Fortunately, he doesn't do it outside. It's obviously a den thing." "He's only reinforcing the pack scent." Suggested Vicky. "Dogs are always sniffing each other." "Well I'm not a dog." "I'm not sure that Zac would agree with you there. If he thinks you smell like a dog, then you'd better be careful around any other dogs, particularly the bitches." She giggled. "If that happens, I will definitely demand that you remove it." Fortunately, there were no other dogs around the campus so Steve was not molested or bothered whilst at work. Most of the time Steve was either in his lab, on his bicycle, at home with Vicky or out in his car. The only really tricky situations occurred whilst he was out shopping for the family groceries every Wednesday. In the supermarket he found himself being constantly 'approached' by other dogs. At first, Steve couldn't understand until Vicky explained that dogs would readily respond to any pheromones that he was inadvertently emitting. The realisation embarrassed Steve tremendously but eventually they resolved the problem. After some intense research, they compounded a 'dog deterrent' to spray on Steve's crotch if he was going out in public. Steve sighed with relief when it proved to work. The pheromone-based scent was an extract from Zac's pheromones and undetectable to a human nose. However, the scent was overpowering to other dogs and left them in no doubt that Steve 'belonged to another pack'! The spray however, did not affect Zac. The base oils consisted of his own pheromones that were now produced in Steve's scrotum and this reinforced their friendship. To Zac, Steve smelt exactly like a brother, another close member of the family pack. The spray solution however, still did not address Steve's frequent and powerful urges. For the first time he found himself looking at Vicky and wishing he could get his leg over. Vicky also sensed the threat and they soon concluded that they would have to resolve the issue. Once again, it was Steve who arrived at a solution. The college was running a new batch of DNA experiments and for this purpose Steve and Vicky had needed more purebred dogs. Having been given the choice, they naturally chose more Alsatians and once again, the labs needed some more human DNA donors. Steve persuaded Vicky to donate some of her DNA for inoculation into one of the embryos and a few months later the DNA compatible litter was born. Vicky was infatuated with the beautiful little bitch that had received her DNA and when the experiments were completed she adopted the young lady dog as a pet for herself and a wife for Zac. They called her Zeta. Steve fell for Zeta hook line and sinker, as did Zac who was soon showing considerable interest in the delectable young addition to their pack. Especially as the genetically modified young bitch gave off a clear scent that resembled Vicky's. At first the dogs slept at the foot of the bed but it wasn't long before the four of them found themselves sleeping together. Steve and Vicky's 'scents' proved irresistible to the dogs. Then one night the inevitable happened. Steve was disturbed in his sleep by Zac's eager attentions to Vicky. He woke sleepily to feel Zac's loins busily pleasing Vicky. The bed was shaking and Vicky was whimpering with delight as Zac panted urgently. Steve was aroused by the action and rapidly became horny. His hand wandered to his crotch only to find another wet little nose that had beaten him to it and was probing his genitalia inquisitively. Zeta's sensitive nose had immediately detected Steve's aroused condition. She started squirming eagerly as she twisted around to press herself against Steve's crotch. For long seconds Steve felt guilty about his thoughts but as Zeta wriggled and 'presented' herself, he realised the two of them would only be repeating what Zac and Vicky were doing. 'What's good for the goose, is good for the gander,' he concluded. After finally convincing himself that he and Zeta were harming nobody else, he gently introduced his rock hard organ to the threshold of Zeta's sex. The eager bitch let out a whimper of frustration and Steve felt her vulva growing damp. 'The little lady was begging for it', he concluded. He tried to gently introduce his organ but there was too much resistance so he turned over and whispered in Vicky's ear. "Do you have any lubricants?" Vicky giggled as she realised what was happening. She was lying on her back with her legs parted whilst Zac was servicing her 'missionary' style'. He was in the sitting position with his haunches raised slightly and his forepaws placed either side of Vicky's chest. As he thrust eagerly away, his warm furry coat brushed luxuriously against her sensitive breasts. For Vicky it was an excellent situation. There was no weight upon her chest and her hands were free to attend to any need. Without breaking her rhythm, Vicky reached to her side of the bed and groped for the familiar tube of ointment. She slipped a tube of K.Y. Jelly under Zac's belly and held it out for Steve to take. "Here use this. Zac and I use it now and it make's things much easier. Now you be gentle and mind you don't you hurt her!" She scolded. "Would I ever hurt anyone," Steve riposted as he took the tube and gently fingered Zeta's eager sex. Then he rubbed his own organ and re-introduced it to Zeta. The eager young bitch squirmed again and Steve felt his organ slipping ever so slowly into her tight slippery tube. He groaned with delight as Zeta whined and squirmed until he felt her bushy posterior pressed hard against his pubis. With a fricassee of delight, Steve realised he was all the way in. Sensing her fulfilment, Zeta started humping Steve's cock with an eagerness that Steve just couldn't comprehend. He had thought that Zeta would have been tense and nervous because of the mismatched sizes of their respective sex organs. Instead, he was delighted to find that she could accommodate him fully and indulge her own needs. Zeta was really enjoying herself. Steve's eyes screwed up tight as the ecstatic sensations started to bring him to climax. As his tension grew, Zeta seemed to sense his impending climax and started grinding herself hard against his pubis. Steve was then surprised to feel a stiff little nubbin harden as it pressed against the base of his cock. He suddenly realised that Zeta had some sort of clitoris and she was frotting herself as eagerly against his cock as he was pounding her sex. Suddenly his orgasm started to boil and he gave a series of tremendous thrusts as he exploded with lust and Zeta let out a long low whine. He continued pumping eagerly until he finally he collapsed with satiated delight and twitched as the waves of pleasure slowly ebbed away. It was only then that he realised that Zeta had also fallen quiet. He concluded they might just have orgasmed together. He hadn't realised that bitches had orgasms. Strangely, he found that his cock remained hard and he wondered if the canine testosterone might have caused this. Then he realised the truth. Zeta also had some sort of sphincter ring inside her vagina and it had tightened around his swollen cock. Her tightening sphincter had prevented the blood from properly returning from his cock. The increased pressure had caused some sort of bulge to grow in the middle of his cock. This made it quite impossible to withdraw his cock past Zeta's vaginal sphincter. The bulge wasn't painful; indeed the sensation was positively delightful, but try as he may, he could not withdraw his cock. He was well and truly tied to Zeta. He had always known that dogs became tied because the male had a knot in his cock but this was a surprise for him. 'How on earth had Zeta's compressive sphincter managed to cause his cock to form a knot?' Deciding that there was nothing he could do about it just then he decided to let things take their course. He had little choice. Zeta's sphincter ring was clamped tightly around his swollen penis and he found himself securely 'tied' into Zeta's scabbard. No matter how he tried, it was impossible for him to withdraw. Fortunately, the ring was not too tight as to completely block of the blood to his erection but it was enough to prevent him becoming flaccid. He was securely tied to Zeta and his cock now felt extremely sensitive. At first he was a bit apprehensive but as he realised there was no pain he calmed down and started to relish this newfound situation. He settled quietly on his side and gently drew Zeta into his arms. She curled up against him and he finished by wrapping his arms around his newfound mate. In this tied embrace, they fell into a deep slumber. Beside them in the bed, Vicky lay silently contemplating this new development while she stroked her own partner Zac. What Steve didn't know was that when Zeta had been undergoing the transplant experiments, Vicky had secretly grafted the vaginal sphincter from another species. This sphincter modification plus an enlargement of her vaginal scabbard had turned Zeta into a very special type of bitch. She had become a partner that could easily accommodate Steve's cock and enjoy it. Zeta was programmed to enjoy sex because the extra little nubbin that Vicky had also created now functioned as a clitoris for Zeta. The nubbin was a miracle of micro surgical engineering and was every bit as sensitive and erotic as a human clitoris. Once Zeta had actually orgasmed from the pleasure of sex with Steve, she was to become utterly besotted with him. Furthermore, she had no human hang-ups about wanting sex any time, anywhere. Vicky smiled inwardly. Her mutated female pet would always be able serve Steve's newfound needs perfectly. Steve and Zeta were now a perfect match. Satisfied that she had provided properly for Steve's elevated libido Vicky lay back luxuriously and savoured her own pleasures from Zac. She felt Zac's knot growing larger than it had ever done before and discovered she could not escape. Her vaginal scabbard was tied absolutely 'lock-solid' to his penis. Vicky was not surprised. She realised that Zac still considered Vicky to be the 'Alpha bitch'. By staying tied to Vicky; Zac was simply protecting his investment. Nothing but surgery could have removed Zac's swollen cock for his knot had grown like a ball inside Vicky's cunt. Vicky grunted with the pleasure and humped herself hard against her doggy partner to convince him that there was no risk of him losing his Alpha bitch. Zac's knot stopped expanding and Vicky sighed with relief. Thus comforted and satiated, Vicky fell asleep with Zac tied tight inside her. Eventually, the four of them huddled into a large mass of limbs and fur that slept until the morning. At dawn Vicky and Steve discovered that they were still tied to their respective partners. They tried to get up but found that without the co-operation of the dogs, neither of them were going anywhere. Gently Steve manipulated Zeta onto the floor then slid off the bed himself to find himself securely tied inside her and only able to walk with her leading the way. His penis was still extremely sensitive and the slightest tug or twitch from Zeta sent pulses of uncontrollable lust through Steve's loins. Unless he followed Zeta exactly, he was going to be reduced to an orgasmic wreck. There was nothing he could do but follow Zeta and 'obey' her every move. Thus conjoined, Steve had to walk with bended knees as he followed Zeta to the kitchen. She turned to look expectantly at her new partner then whined for food. To reach the dog food, Steve had to stand upright to reach the cupboard. When he stood straight, Zeta's rear legs were lifted off the floor. Instead of whining or growling though, Zeta simply clamped her vagina tighter and squirmed affectionately. As he stretched up to the cupboard, Steve felt a lightening flash of pleasure crash though his loins and he gasped as he opened the dog food packet. As he struggled to concentrate on filling Zeta's bowl she continued to clench her sphincter around his cock. Steve started to gasp as another orgasm built up pressure in his loins. "Ah! Stoppit! You naughty girl," he squeaked weakly. Zeta ignored his commands and simply clenched her sphincter tighter then growled, as she demanded her breakfast. Steve just managed to bend over and place the bowl under Zeta's nose before he collapsed back into the large kitchen chair. There he squirmed and pumped uncontrollably as his orgasm overwhelmed him. For a few moments, his world went dark and he saw stars as the orgasm sent him into oblivion. Then finally, as his body was drained of all control or resistance, he slumped in the low wooden spoke-backed chair. When he finally recovered, Zeta was still chewing her food. She twitched her sphincter again and Steve felt the seeds of a second orgasm starting to build. It was obvious that by simply twitching and clenching her sphincter, Zeta could control Steve completely. Thus brought into obedience by Zeta's dominant vagina, Steve sagged back into a chair and sat still while Zeta finished her food. With her servant thus subdued, Zeta seemed to ignore her bondservant cum sex-slave and simply ate her food whilst still holding Steve firmly clamped in her vagina. Thus secured by his sensitive cock, all Steve could do was reach carefully across the kitchen worktop to switch on the coffee percolator. The sound of sex and Zeta munching the dog food alerted Zac. He padded into the kitchen towing a gasping Vicky behind him. Steve looked up from the chair to find Zac towing a red faced Vicky who was tied helplessly to his cock. Zac's cock was hinged backwards and still knotted tight inside her. Fortunately, because of Zac's size and height, Vicky could walk normally. Zac's penis exactly matched Vicky's groin height. Vicky however could not resist Zac's superior strength, so wherever Zac went, she was forced to follow. "D'you need a chair?" Gulped Steve self-consciously. "Uhhm. No." Replied Vicky. "I can't sit down in that wheel back chair because it's too low. I'll have to sit on one of the breakfast bar stools. I can't get away from him. I'm stuck to him." "So am I." Replied the red-faced Steve. "She wont let me go. Vicky and Steve shared embarrassed grins as they were forced to wait obediently behind their pets whilst the dogs devoured their breakfast. "It's strange," whispered Steve, "normally I need a pee in the mornings but today my bladder is still empty." "Same here," replied Vicky. "I wonder how long we're going to be stuck like this?" "What! You mean you don't know!" Gasped Steve. "I'm a vet, not a clairvoyant," riposted Vicky. Steve swallowed nervously. "Shit! I've got to meet a colleague this morning." "You'd better cancel." Thus they remained for fully thirty minutes patiently sipping coffee with their partners still attached to them. There was little else they could do until they were 'released'. After finishing their food, the two dogs turned to lick each other affectionately. Vicky wondered if the dogs were somehow establishing the status quo in the 'pack' by forcing her and Steve to submit to their will. They were becoming embarrassed by their predicament until they each felt the dogs slackening their grips. The sphincter in Zeta's cunt expanded and allowed the blood pressure to subside in Steve's cock. His cock shrank quickly and he slipped out of Zeta's sex with ease. Once separated, Zeta turned eagerly to sniff and lick the delicious organ that had so pleasured her all night. Steve gasped with lust as Zeta's tongue stimulated his cock and it responded with an immediate erection. "Bloody hell. I wouldn't have thought it possible," croaked Steve, as he crushed his thighs together and minced awkwardly back to the bathroom. After Zeta and Steve were separated, Zac now deemed there to be no threat to his coupling with Vicky. Vicky determined that his responses were determined more by smell and pheromones than by sight. He deflated his knot and Vicky finally eased herself off the delightful organ. She joined Steve in the shower while Zac and Zeta indulged themselves in conventional doggy sex. There was no chance of Zac getting Zeta pregnant because he now owned both of Steve's testicles. He only ejaculated Steve's human sperm. As Zac and Zeta screwed, Vicky chatted with Steve in the shower. "Are you sore?" She asked. "No." Replied Steve. '"But I'm horny as hell. Look, he's ready and willing to come again." Vicky gasped at the speed with which Steve seemed able to recover. She ran her fingers over Steve's strong shoulders and squeezed against him affectionately. Steve sensed her nervousness and simply stood savouring the hot shower as the water poured in rivulets down their embraced bodies. "D'you think you'll ever be well enough to accept me?" He whispered softly. "Maybe. Just let's go one step at a time. I've managed to embrace you while we're naked and horny. That's a big step." Whispered Vicky Tearfully. What Vicky had not realised was now that Steve couldn't get her pregnant, she sublimalally considered him to be no threat. The lack of threat or risk made Steve appear more acceptable. Her swapping of both Steve's testicles into Zac had unwittingly released her fears. Steve was no risk therefore Steve was becoming acceptable. Steve for his part savoured Vicky's embrace and manfully struggled to prevent another orgasm from exploding from his loins. 'Hell! He felt so horny again! What was wrong with him?' He wondered. Eventually he lost control and grunted apologetically as he turned away from Vicky and exploded against the shower tiles. "There's no need to feel ashamed." She whispered. "But, I can't stop it." He groaned tearfully. "I get so turned on!" Vicky sucked her lip nervously. Gently she extended a nervous hand and cautiously touched the rigid organ. She felt a quiver of fear mixed with a fricassee of lust as his organ twitched responsively to her touch. "Don't do that," begged Steve. "I can't answer for my responses." Reluctantly, Vicky withdrew her hand. 'She had been 'Oh so brave!' just to touch him.' Finally, they emerged from the shower to find Zac and Zeta tied butt to butt. Zac looked up woefully at the humans and they grinned as they realised Zac's predicament. "He's tied to her until she releases him." Grinned Vicky. "Yeas. I meant to ask you about that." Remarked Steve. "Bitches don't normally have a sphincter in their vaginas do they?" Vicky grinned as her face reddened guiltily. "It's a little modification I made when she was in my lab." "Go on. Though I'm not sure I want to hear this." Frowned Steve nervously. "Oh it's nothing serious." Assured Vicky. "Some other mammals have a sphincter in their vaginas to ensure that they remain coupled until the female has actually conceived. I simply bred the animal to make it genetically compatible with Zeta and then grafted a sphincter into Zeta's cunt. I also enlarged Zeta's cunt scabbard to accept your cock. You'll have noticed how relaxed she was when you penetrated her." "Yes, and I noticed that she had a clitty, or something remarkably similar. She couldn't stop frotting herself against the underside of my cock." Vicky grinned secretively again. "That's another little wonder I have developed. It took some special microsurgery but I succeeded in grafting a clitty into Zeta's sexual response nervous system. I genetically engineered an organ growth from some donor tissue taken from my own clitty. I then transplanted my cloned human clitty into Zeta's cunt and now she orgasms like a girl. That's an exact version of my clitty you felt when Zeta frotted herself against you. It's grafted into her cunt at the threshold by the sphincter so that every time a cock enters her vagina, Zeta orgasms. The sphincter then spasms and clamps tight onto the invading cock. She's become a right little nymphomaniac, look." As Vicky spoke, Zeta was once again humping eagerly against Zac's reversed cock and whimpering. Steve bit his lip as he watched the dogs indulging again. "Is Zeta's sphincter trapping Zac's knot now?" "Probably." Replied Vicky. "So Zac can't escape until Zeta allows him." "Call it bitches' lib." You only get to shag Zeta on Zeta's terms," giggled Vicky. Steve then fell silent as he remembered how he had been tied. "Have you put a dog-knot inside my cock?" Vicky gulped silently then lowered her head guiltily. "You did it when I fainted during the transfer surgery I suppose," accused Steve. Vicky remained nodding silently as she stared at the floor. Steve wasn't sure what to say. He wanted to feel angry but the sex with Zeta had been fantastic. He sat to the kitchen breakfast table and poured himself another coffee. Vicky aimlessly fiddled with her cup under the tap as each of them tried to gather their thoughts. Zac seemed to sense the tension and whined as he dragged Zeta backwards and pushed his nose under Steve's elbow. Steve looked down into the big brown eyes and his heart melted. Vicky sat down opposite Steve and remained silent. She couldn't look him in the eyes. Zeta sidled under the table then pushed her nose into Vicky's crotch and licked gently at the delightful scent. Vicky twitched then gasped. Her reaction brought Steve out of his introspection and he stared at her. "So every time I have sex, I'll grow a knot in my cock." "No. Only if Zeta's sphincter compresses the base of your cock to retard the return of blood." "So with a normal woman or bitch I'd be OK?" "Yes. If there's no sphincter, your knot can't grow." Steve fell silent as he weighed up the pros and cons. "So what your saying is that Zeta and I are made for each other." "You are now." Confessed Vicky reluctantly. "So what animal provided the sphincter?" Vicky named the animal and Steve remembered Vicky caring for and feeding several of them in her labs. "Will the sphincter prevent her having pups?" "Of course not. When she's not aroused, the sphincter is undetectable. It expands as large as the rest of her cervix and birth canal when her labour pains kick in." Steve relaxed a little. 'At least Zeta could enjoy a normal life even if she did need serving several times daily.' Then he felt a fricassee of pleasure twitch through his loins as he anticipated who would have to do most of that serving. 'Vicky had certainly addressed the needs of his accelerated libido in a particularly apt manner. He always loved both the dogs but now there was this extra sexual dimension.' Thus partially mollified, Steve finished his coffee and dressed to meet his appointment. 'Life was certainly going to be interesting in the Morgan household,' he chuckled.
