Chapter 79

("Oh, fuck...") thought Rumi, biting her lip as she sat hunched over in Izuku's lap, her entire body quivering as he massaged and pulled on her nipples. At the same time, his cock practically 'swirled' inside her vagina, spinning and undulating as her uterus endeavored to swallow his entire dick.

Releasing his hold on Rumi's breasts, Izuku caressed the outside of her thighs, moving his hands to the backs of her knees before pulling her legs up and forcing her to sit flush against him. Then, with her knees touching her shoulders, he resumed teasing her nipples as he whispered, "Rumi..." into the tuft of her ear.

Clenching her pussy involuntarily, Rumi writhed in Izuku's embrace as she exclaimed, ("Fuck...!") in her mind. She had wanted, maybe even 'needed' him to conquer her, but she didn't think it would happen so quickly. It had barely been three hours since they began, but she felt like trillions of ants were crawling across her brain due to the intense pleasure.

"You're so beautiful..." whispered Izuku, his voice low and filled with heat as he added, "My Rumi..." as her body tensed and trembled in the wake of her 318th orgasm. She had more or less been cumming non-stop since he blew his load directly into her womb, but some of her orgasms were a lot more intense than others. None more so than when he held her close and whispered her name...

"Kuh...don't...get carried away..." said Rumi, even as tears streamed down her face due to how glazed her eyes were. Her complexion was also a lot redder than normal as her tail twitched involuntarily against Izuku's lower abdomen.

Planting a kiss on Rumi's shoulder, Izuku whispered, "I'll prove it to you..." before abruptly lowering her legs and lying back on his bed, hands behind his head, eyes closed, and smiling as he hoped his gamble paid off.

Staring back at Izuku with half-lidded eyes and a discernably wistful look on her face, Rumi briefly considered ending things out of spite. However, that was only a passing fancy of her brain. Her body craved even greater pleasure, so, despite feeling a powerful compulsion to punch Izuku in his face, Rumi placed her hands on his knees and began to shake her hips as she grumbled, "Cheeky bastard..."

Grinning from ear to ear, Izuku said, "That's my girl..." before bucking his hips, sending a shiver through Rumi's body as he said, "I know you can go faster than that..."

("This fucking brat...") thought Rumi, even as she sped up her movements. Izuku's 'arrogant' behavior made her feel indescribably frustrated, but her body reacted differently. In the past, she primarily focused on getting off without showing much consideration for her partner. With Izuku, she felt a strong desire to make him cum. He had already discharged his seed in her deepest parts, but her body craved–no, it demanded more.

Closing her eyes and intensifying her movements, Rumi's frustration reached a critical level as she asked herself, ("How can I hate and love something so damn much!? Fuck! Fuck! Fuck...!)

Timing her internal exclamations with the swelling of Izuku's cock, Rumi trembled from head to toe as she felt the warmth of his semen filling her womb. Then, for the briefest moments, her vision and mind went white, her body collapsing like a marionette with its strings cut. Fortunately, the moment she fell forward, the tendrils from Izuku's Blackwhip ensnared her, functioning as replacement strings to hold her upright until he sat up to embrace her.

Showing no mercy to the buxom bunny girl, Izuku resumed massaging Rumi's breasts as he asked, "Did my cumming inside you cause you to pass out? That's fucking adorable..."

Regaining her senses, Rumi instinctually bumped Izuku's nose with the back of her head, her expression an aggressive pout as she replied, "Fuck you..." between panting breaths.

Ignoring the blood trickling from his left nostril, Izuku replied, "I prefer fucking you..." before pulling Rumi to lay sideways with him on the bed, whispering, "Now you won't have to worry about falling..." as he reached down to caress her clit.

("God dammit...!") groaned Rumi, who, for the first time in her life, was thinking about taking a break to 'cool down' during sex. Her body was on fire, hungry for even greater pleasure, but she felt like she was losing her mind as Izuku handled her like they had been having sex their entire lives. In reality, while Izuku was fairly experienced, the thing affording him the edge against Rumi was his Vitality and Dexterity, temporarily exceeding 4000 and 2000 thanks to the power of One-for-All and a re-roll. He was temporarily as dumb as a brick, but that actually worked in his favor since all he could think about was fucking the beautiful rabbit woman senseless and getting her to submit...

Observing Rumi grinding his cock with a red, uncharacteristically subdued look on her face, her body garbed in a literal bunny girl outfit with fishnet stockings, Izuku mused, "To think I get to see such an incredible sight the rest of my life..."

"Kuh..."

Though she wanted to refute Izuku's words, Rumi ultimately just closed her eyes and focused on moving her hips, whimpering moans emanating from her throat as the former pressed his thumb to her clit, a thin tendril of Blackwhip coiling around it before he gave it a gentle pull.

"Things would be easier if you submitted..." asserted Izuku, his voice lowering as he added, "Though if I"m being honest, I wouldn't mind if things remained this way forever...your ferocity and stubbornness are two of the things I love most about you...Rumi..."

Furrowing her brows deeply, Rumi almost appeared to be in pain as she opened her eyes a crack, staring up at the ceiling as if she would find the solution to her conflicting emotions written upon it. More than twenty-four hours had passed since she and Izuku started having sex. As a result, her body was in a truly 'agonizing' amount of pleasure, but she couldn't stop. At this point, the only person who could bring things to an end was Izuku, but he kept 'tormenting' her without end, whispering loving words that caused her brain to tingle while he came inside of her over and over and over again...

Providing Rumi the smallest glimmer of hope, a knock suddenly came from Izuku's door, followed by the sound of his mother's voice coming over the intercom he had installed, asking, "Izuku-chan, are you in there, sweetie? Since you're going to be busy tomorrow, I invited Toshinori-kun to celebrate your birthday a little early."

("Oh, thank God...") thought Rumi, falling backward and sprawling out atop Izuku's legs with his cock still inside her. Her body protested, but now that they had a reason to stop, the spell preventing her from doing so was broken.

Rising to a seated position, Izuku rubbed Rumi's belly with his palm, his expression, and tone gentle as he said, "Looks like we'll have to continue our fuck fest another time. Go ahead and head over to the shower. I'll be there in a moment."

Staring down at Izuku from her lying position, Rumi remarked, "You need to take your cock out of my womb first..."

Since her cervix had effectively formed a vacuum seal around the upper third of Izuku's cock, Rumi had no way of disconnecting from him without risking serious injury. They were like two dogs locked in coitus, so unless Izuku released her, she was adhered to his dick like a cocksleeve.

"Right..." replied Izuku, breaking the 'seal' of Rumi's cervix and allowing a startling amount of semen to burst out of her extraordinarily tight pussy, blanketing his crotch and lower abdomen. The thing he had been patting was the conspicuous bulge his semen had created in her belly but seeing his semen shoot out of her left Izuku at a loss for words as he internally asked himself, ("Did all of that seriously come from my balls? 4000 Vit is no joke...")

Climaxing from the abrupt release of pressure, propelling Izuku's cock out of her body, Rumi was seriously tempted to close her eyes and fall asleep. Before she could, Izuku gave her outer thigh a light smack, saying, 'Sleep after we've washed up and changed my bedding. I don't mind lending you my bed."

"Ugh..."

Rolling off of Izuku's legs and onto her stomach, Rumi briefly considered rolling onto the floor before turning her body and sitting upright. Her body felt unbelievably lethargic, like she had an intense fever, but she managed to get to her feet, her perfect ass swaying like the ring of a hypnotist as she meandered her way to the bathroom, semen dripping down her thighs and leaving a trail from Izuku's bed...

("I'm going to fuck that woman so hard...") thought Izuku, tearing his eyes from Rumi's ass at the last moment to hurriedly make his way to the door, pressing the intercom button to answer, "I'll be out in a few minutes, Kaa-chan."

Though she had already turned to leave, Inko came back to ask Izuku if everything was okay and if she should prepare another plate downstairs. Izuku hesitated to answer, but Rumi, having heard Inko's query from the bathroom, called out, "I already told you I don't give a shit if people learn of our relationship. I'll have to meet your mother sooner or later, so I may as well join you for breakfast, lunch, or whatever..."

As he also wasn't ashamed of his relationship with Rumi, even if they were just mates, Izuku pressed the intercom's speech button and responded in the affirmative. What followed was an incredibly awkward scenario where his mother practically stared daggers at Rumi, not expecting the girl Izuku was keeping in his room to be so 'old,' but with Toshinori helping to lighten the mood, things weren't too bad...

"Do you really have to go...?" asked Izuku, seeing Rumi off at one of the school's more isolated gates.

Furrowing her brows, Rumi replied, "Don't be overly sentimental. It's not like this is the last we'll be seeing each other. Just let me know when your Summer Training Camp ends. You can come to my place, and I'll train you a bit before the second term..."

Reminded by Rumi's words, Izuku revealed, "The girls will be spending the final few weeks of Summer Break at one of the Yaoyorozu Estates. I won't force you, but I'd like you to meet them..."

Rolling her eyes, Rumi replied, "Yeah, whatever. Just don't expect me to play nice. I've never been good at sharing, so if those brats try to get in my way, I'll have to teach them who's at the top of the pecking order..."

Adopting a smile, Izuku mused, "Just don't go too overboard..." before giving Rumi a light smack on her bottom, grabbing a handful of her ass cheek in the process.

"..."

Regaining a hint of the 'timidness' she had shown near the end of their twenty-seven-hour fuck fest, Rumi's expression became incomparably alluring as she asked, "Are you trying to get me to pounce on you right here...?"

"It wouldn't be the first time I fucked outdoors..." admitted Izuku. "But I know there are villains waiting to have their asses kicked and people who are depending on you to save them, so I won't monopolize you too much. Just prepare yourself for the next time. I'm still not convinced your heart and body belong to me completely, so I intend to keep fucking you like a beast until you submit fully..."

Punctuating his words, Izuku gave Rumi's rabbit-like tail a light pinch. It was an especially sensitive part of her body, so an electric-like shock ran up her spine as he did so. Unfortunately, not that he had any complaints, his actions were the proverbial straw that broke the camel's back. Rumi was already at her limit, so she abruptly threw him over her shoulder and carried him deeper into the surrounding forest, away from any footpaths or prying eyes, before throwing him down and attacking him in the middle of a clearing...
