In Kaito's contract, it was a requirement that he work out to retain a lean yet muscular build. Crypton wanted him to be beach-ready if they needed him to be, ready to show off the goods at any time. His producer put in perspective of male anime character types. Gakupo Kamui was the beautiful and sensitive biseinen. Len Kagamine was the cute and innocent shota. Kaito's personality was the sexy and suave bishonen. In order to complete the trilogy, he had appeal to a fanbase desiring masculinity. That meant muscle.
So, today he was waiting for his fellow idol Luka Megurine to arrive at his penthouse apartment. She had offered to be a personal trainer for him because his regular one was unable to make it, and this is the first time she was going to come over. He was sitting on the couch in a t-shirt and athletic shorts, waiting for her to arrive.
Knock-knock!
Kaito got up and opened the door. Luka Kamui (neé Megurine) was standing there with a cocked hip, clad in a skimpy white tank-top that revealed a decent amount of her midriff and a pair of black and white dolphin shorts with red Converse sneakers and white calf-length socks. Her pink hair was tied up into an attractively tomboyish ponytail. On her hand was a wedding ring.
"Hey, Luka! How are you doing?"
"I'm fine," she greeted him politely before stepping inside. She smiled at him before opening the door to the weight room in his apartment. Kaito followed her inside, just to see her lay down the exercise equipment on a bench.
As usual, Kaito removed his shirt to start doing his training. His trainer was okay with it, so it wasn't really a problem with him; why should it be a problem with her? The young man couldn't help but notice the fact that Luka looked away from him with her face being red as a tomato.
"Alright...your personal trainer has instructed me on your routine. So let's get started on some stretches…"
Kaito was familiar with these exercises, so he went along with them. For a few hours, Luka and Kaito lifted, stretched, and trained his body to it's limits. However, one thing became noticeable after a while. The pink-haired woman needed to relieve herself quite a bit and her nipples were straining through her sheer shirt.. He continued to train his body while she spent a large time in the bathroom.
The blue-haired young man was getting increasingly annoyed with her constantly leaving him to do absolutely nothing. When he was doing pull-ups, he decided that he would try to investigate what the hell she could be doing in there.
"I'm sorry, I have to go to the bathroom…" she declared. It was his opportunity.
"But you just went…"
Once she exited the room, Kaito let himself down from the pull-up bar and followed suit. Then, he followed her to the bathroom. The door was closed, but the woman hadn't locked the door; he inferred that she had rushed through and had forgotten. Clearing his throat, he knocked once.
"You in there?
When Kaito opened the door, his face went bright red. Luka sat on the toilet with her panties down to her ankles, legs spread apart to reveal her sopping pussy. Her right hand lay in front of it, while her other hand gripped one of her large breasts through the sheer cotton fabric of her tank top. Her face was bright red and sweating heavily as she dug her fingers inside her cunt.
"Mmmph...hah...Kaito-sama...I need you to fuck me because I'm so horny...stop teasing me and drive your cock through me…"
Luka slipped a bit of the tank top off to reveal her right breast. The massive udder swung forth from the opening and dangled off her chest. Fondling the surface, she then pinched her erect nipple and softly moaned. The young man in the doorway went red with embarrassment and turned to walk away.
"I'm sorr-WHOAH!"
Before he could say anything, Luka got up from the toilet and grabbed his wrist. He felt himself being dragged through the penthouse until they ended up in his bedroom, where the pink-haired woman threw herself onto his bed and slipped off her shirt to reveal the massive breasts on her voluptuous figure. Her E-cup breasts jiggled slightly as the shirt left her body.
"Luka…"
"I need to fuck...you make me so horny~!"
Kaito gulped as Luka, sweating and breathing heavily, got down on all fours and blatantly present herself for him. Her nice and tight ass was bulging through the tiny pair of tights shorts, a dark elliptical stain around her crotch. She wiggled it slightly as she enticed him forward.
"I'm so horny it's like I'm an animal in heat…Please, you have to satisfy me…" she moaned. Kaito sighed before removing his athletic shorts to reveal the fact that he was already hard as a rock. Moving towards Luka on the bed, he felt up her butt before giving it a decent smack. The woman with pink hair yelped in pain that turned into pleasure.
"More, please…" Luka begged. Kaito smirked before he gripped her shorts and panties. He pulled them down with great force to reveal her nice and tight bubble butt as well as her sopping wet pussy. Gripping her cheeks, the young-man with blue hair and blue eyes pushed his cock inside her asshole.
"Haah...it's so big! Bigger than my husbands!" Luka gasped as his cock settled itself inside of her. Gakupo was never the one for anal sex. When Kaito began to thrust into her, her moaning increased in volume and mixed with the squelching sounds from having his massive cock thrust into her ass.
Rapidly pushing his hips forward and backward, he drove into her ass. Luka's whimpers and moans were turning Kaito on more and more. Looking at the pale and spotless butt in front of him, an internal smirk formed on his face. He felt the smooth skin of her cheeks and gave them a couple squeezes, and Luka responded with loud and slutty moans, For Luka, his touch was amazingly stimulating. It sent waves and waves of pleasure throughout her body and quickly found herself becoming a pleasure-addicted slut. She couldn't think about anything other than the cock inside her ass and how every single problem in her life disappeared with it inside of her.
While continuing to thrust forward into her anus, Kaito wrapped his left arm around Luka's tiny waist in order to lift her face up to his level. She, in turn, hooked her slender right arm around his neck. They entered a deep and messy kiss, their tongues visible in the gap.
Mmmm...aahn...chuu...
The saliva they exchanged began to drip down the other's cheeks, then pulled away from each other. The two removed themselves from each other's arms, and Luka let herself down to press her breasts against the floor. The satisfaction and ecstasy he was giving her as she lay down on all fours like a dog was mind-numbingly glorious. She couldn't hold herself back any longer; she had to do what she had to do when she was in the presence of such a handsome and strong young man.
"My ass feels so good...keep going…haah! It's being reshaped to fit Master Kaito's cooock!"
Hearing her call him "Master" caused a bit of shock in Kaito Kaito was merciless when he was fucking her, enjoying the feeling of domination that caused her to beg and cry in a completely whorish manner. He wasn't normally into this sort of maledom play, but as long as she was happy with it he was perfectly willing to go along. It didn't feel to bad for him, either; her ass fit tightly around his cock. Her ponytail fell away from her head, letting her soft and silky smooth hair tumble down her back.
"Master...I'm cumming!"
"Me too!"
Kaito felt her asshole clamp down on his increasingly pressure filled cock before he let loose a large amount of spunk from his dick. Cum flowed inside her anus, painting the inside of her ass white. Her eyes rolled back and her tongue lolled out in the most slutty and shameless way that Kaito had ever seen. Luka's world of reason and logic seemed to fall away, replaced with an instinctual drive to breed with an alpha-male. She couldn't stop anymore, but the bliss and ecstasy of her orgasm was broken for a few moments. Looking back, she saw that his cock had exited her asshole and was standing upright. As Luka gazed upon the thick and veiny pole and the massive testes that were filled with sperm, she felt herself drooling.
Kaito thrusted into her at high speed and with ferocious intensity. The feeling of her pussy was amazing; it was soft and warm and wet, and it felt so good on his cock. With each thrust into her pussy, her ass and breasts jiggled up and down. Loud squishing noises echoed throughout the room as he pounded her over and over again. Luka's mind was going blank with pleasure, and all she could think about was the feeling that he was giving. She could live like this forever: just drowning herself in pleasure day after day, night after night. If she went back to Gakupo, he couldn't even make her moan let alone cum.
"Oh,yeah...fuck me more...fuuuuck...I'm such an unfaithful goddamn slut…" Luka panted.
"Indeed you are," Kaito growled with a wry smile on his face. The blue-eyed man gritted his teeth and gripped Luka's ass as he hammered her insides, his fingers indenting into the deep skin of her butt. Her moans increased in volume until he felt her walls close down upon his cock at a high speed. A shiver ran down her spine as she orgasmed. Her back arched, causing her breasts to wobble.
"UAAGH!" the pink-haired woman cried out as she squirted out of her pussy. It was better than anything that Gakupo could have given her; the guy couldn't even come close to matching the sex machine pumping his massive pole inside and out of her slutty cunt. Sweat poured off their bodies as the two fucked like animals, abandoning everything to their breeding instincts.
Continuing to pump into her pussy, Kaito spanked her once more. She whimpered while she let masochistic pleasure. Suddenly and without warning, he lifted her up and slammed her against the window of the bedroom. Luka's breasts pressed up against the window looking out over the city streets. Her face was bright red and she was breathing raggedly while her tongue hung out of her mouth.
"Master's massive cock is shaping my insides so that I can only cum with his dick…"
Kaito pulled the pink-haired woman into another deep kiss, allowing her to feel his torso muscles. They were hard and thick, making her somehow even more aroused than she was. Luka didn't feel ashamed any longer for sleeping with another man. She was deeply in love with the man who was fucking her right now, and she never wanted to leave his side. The blue-haired man had a touch that made her feel like she was floating up to heaven, an ecstasy that she had never felt before. He made her cum over and over and over again like she had never cum before. He was worthy of being called "Master", and thus making herself available for him to satisfy his sexual drive whenever he felt like it would be perfectly fine.
The moaning and groaning of the two animalistic lovers was loud, punctuated with the screams of every orgasm that Luka felt. The fact that they were in a luxury penthouse apartment was the saving grace of the people below them, who otherwise would have heard every single sound of flesh slapping against flesh and all the moans and whimpers from the two. Luka's erect nipples slid up and down the window.
A tingle traveled up Kaito's spine while he thrusted into his new harem member. He let out a sigh while Luka's pussy tightened on his cock. As his massive member slid in and out of her hole, he felt the pressure of all of his cum build up. Kaito tried his hardest to hold it back, letting his lover cum many times. However, he unconsciously sped up the rate of his hips to the fastest he had ever been.
"Huh...hah...ugh...I'm gonna cum inside of you, Luka!"
"Go ahead! I want it all inside of me! Cum loads inside of me~!"
Kaito felt the pressure relax on his dick and a rush of pleasure run through his body. He let loose a laminar stream of white fluid that rapidly filled up Luka's uterus, watching her eyes roll into the back of her head. as she felt the warmth emanate from inside her stomach.
Kaito slid his cock out from Luka's pussy, catching her as she fell to the floor before carrying her to the bed. She slumped down onto the ruffled bedsheets and looked up at him with a weak smile, lidded eyes, and an open mouth. Her breasts lifted up and down with her ragged breathing. Cum was still dripping out of her ass and pussy. When the blue-haired singer lay down next to her, she cuddled up to him and began to caress his torso.
"Master…You're amazing," Luka panted, "I've never been so happy, so I'm going to be your devoted sex slave. Miku was right. I would love to be a member of your harem."
"She told you about what happened? That's why you're here?"
"Yup. She said that you deserve a harem of slutty women."
The ego-stroking words caused him to blush with embarrassment. For the next few hours, Kaito and Luka continued making love fiercely and passionately. The blue-haired man came inside the pink-haired woman over and over again.
