Saiyan Sexperiments

When Vageta came to, he instinctively kept his eyes closed and feigned sleep as he assessed of the state of his body. He was quite surprised by what he found, or rather what he didn\'t find. He was not sore, nauseous, or disoriented as one would expect to feel after waking up from extensive surgery. Attributing it to his wife\'s amazing skill, he supposed he should be grateful to the amount of effort Bulma had obviously put into designing and perfecting whatever medical techniques she had just performed, but the ease with which she could apparently manipulate and adjust his body was more than a little unsettling.



Vageta\'s train of thought was broken by a firm smack to his naked hindquarters, and his eyes opened to look at his wife standing next to where he lay, still bound to the table he had fallen asleep on.



"I hope you slept well Love, it\'s going to be quite a while before I give you the chance to sleep again. We\'ve got a lot to do."



Seeing the apprehension on her husband\'s face, Bulma decided to indulge him and explain some of the changes she had made to his body. Using modified saiyan medical equipment she had been able to recover from Vageta\'s original travel pod, Bulma had spent the night carefully altering the structure and substance of his bones and muscles to obtain the elasticity necessary to accept a penis of Shenron\'s size, while being careful not to compromise his body\'s normal functions and combat abilities. It had taken some very subtle manipulation to pull it off, but Bulma was quite pleased with the end result. In theory, Vageta\'s body was now capable of stretching to truly prodigious dimensions. There was however, a small catch. While his body now had the potential to be infinitely flexible, it would still need to be trained by degrees to achieve it, and if left unattended it would return to its original state after a period of time. Vageta would thus be spending the next seven days undergoing constant anal exercises, until he was sufficiently warmed up for his big day. While she waited for him to wake up, Bulma had already made the necessary preparations for the brutal regimen she had planned, but before all that she wanted a go at him herself.



With that sentiment, Bulma strolled out of Vageta\'s sight for a moment before reappearing moments later, now holding in her arms the instrument with which he would receive the first of many stretching sessions over the next few days. The device she gleefully showed off could scarcely be called a strap-on - it was far too impressive a piece of machinery. At nearly two feet in length and growing from six inches to a girth equal to one of Vageta\'s thighs, it was significantly larger than any toy she had previously forced into him. The harnessing mechanism alone was necessarily complex, making use of both conventional padded leather hip straps and two apple-sized bulbs that fitted into Bulma\'s own pussy and ass to help act as a counterweight to the intimidating dong. This was not their only purpose, however, as the entire penis was studded with sensors beneath its surface, which would relay the tactile information they received back to the large nodes in her orifices and recreate the sensations it picked up. It was the closest Bulma could get to having a dick without growing a real one, which she actually have the technology to accomplish, though she hadn\'t yet performed the procedure on herself. Forcefully stopping herself from fantasizing about how much fun it would be to pump her own hot semen into her husband, she brought her attention back to the present. Stepping into the harness, she tightened the straps and pushed the the two sizable plugs inside her, the anticipation of getting to test out her husband\'s new body getting her wet enough that she didn\'t require any lube. Pausing for a moment to enjoy the feeling of bulbs slipping past her entrances and the pleasant fullness she felt with them inside her, she proceeded to walk over to between Vageta\'s legs and position herself so the strap-on\'s mammoth head rested lightly against the her husband\'s tight anus.



When Vageta saw that his wife was apparently planning to enter him without any kind of warm up, and more importantly, without any lubrication, he began to panic and buck against his restraints, but was far too well tied to move more than an inch in any direction. Seeing her husbands reluctance and accurately guessing the reason for it, Bulma chuckled lightly and told him not to worry.



"Don\'t be such a whiner Dear, you\'ll be fine. I forgot to mention that while I was fiddling with your body, I made a few extra changes. One of them was to make the lining of your colon and intestines naturally produce and secrete a clear fluid when stimulated, just like a girl\'s pussy would." She didn\'t bother telling him about the tampering she had done to his nervous system to make him far more sensitive than before, he would realize it himself soon enough. Really, he should quite pleased with that change; if her estimations were correct it would have the extra benefit of further increasing his already stellar reflexes.



Having somewhat calmed her frightened lover, Bulma began to lean her weight forward onto the strap-on, causing the broad sloped head of her artificial cock to press inwards against Vageta\'s currently closed hole. Meeting an unexpected amount of resistance considering the thorough workout she had given his ass only a few hours ago, she gave an irritated sigh and grabbed her husband\'s pendulous ball sack, one of the only areas or his body she was strong enough to actually hurt, and gave it a firm squeeze. "Damn it Slut, stop being such a fucking wimp and relax your ass this second or I\'m calling over the entire Z Squad to watch the show." Seeing Vageta\'s muscles noticeably slacken, Bulma returned to her task, and with a whimper and a cry of ecstasy respectively, the dong\'s tip popped past his sphincter ring. Bulma paused to savor the sensation of Vageta\'s moist warm hole wrapped tightly around the head of her cock, then pulled out so she could do it again. She penetrated him several times with only the head, pushing in with less effort each attempt. When she felt he was wet enough, Bulma began working the rest of the cock into her slave, slowly forcing in the first of several bulges along the shaft\'s length, each one a half inch wider than the previous.



For the following half hour, Bulma continued the same pattern; as Vageta proceeded to take bump after bump up his hole, his ass lips regained the puffy redness Bulma loved to see as they were stretched beyond their previous limits by her monstrous mechanical phallus. Part way through their fucking Bulma had noticed that Vageta was near the point of ejaculation, and not intending to allow him to finish before her, she had grabbed a cock ring off the table beside her and without ceasing her rhythmic invasion of his ass had slipped it onto his penis, the large volume of pre-cum being forcefully milked from his prostate making the shaft slick enough to slide it on easily. Having orgasmed numerous times in the last thirty minutes from the combined sensation of having her ass and pussy stuffed and her cock wedged up into the bowels of her bitch husband, Bulma wanted to end the session on a high note. With only the final final nine inch wide bump yet to packed into Vageta\'s ass, she threw her entire weight forward, and watched in delight as her slave\'s ass blanched and strained to admit the final globular invader. Finally the widest part of the dildo slid in, the entire length of the toy creating an easily visible bulge in Vageta\'s body that stretched nearly to his rib cage. Not yet finished, Bulma withdrew the entire length of the dildo and proceeded to shove it right back in again, and after twenty to thirty repetitions all traces of resistance by Vageta\'s sphincter had disappeared. With a final shove, she drove the cock home for the last time while pulling off the ring that was holding back her husband\'s seed. As the couple shared a blinding orgasm, Bulma took Vageta\'s cock in her hand and angled it towards her face as she stroked it, allowing him to splatter his load over his face and chest as she enjoyed his salty taste.



Slowly coming down from her high, Bulma undid the straps and pulled the bulbs out of herself, experiencing small aftershocks of pleasure as she did so, while leaving the entire length of the dildo still embedded in her husband. Without a word, she left Vageta strapped to the table, the toy lodged securely in his ass, where it would remain until she had completed the final preparations for the next aspect of his training.
