Mark Me Thoroughly with Your Seed...♥
I grabbed Haru and pulled him onto the bed, then stripped off my outer clothes and climbed on top of him. Without the outer layer, the only thing covering my body was the skin-tight black bodysuit. Even that left my breasts and pussy completely exposed, making me look far more vulgar than if I were naked.
“D-Detective?”
“My assistant doesn’t mind either, right? So hurry up and lend me your cock♥”
“W-wait a second… What are you saying right now…?”
“Haru’s cock♥”
I straddled Haru’s stomach, rubbing my pussy against his clothes while begging for his cock in a sultry voice. Right now, I was nothing more than a vulgar bitch in heat at the sight of any man. Right after being rescued by Haru, I’d still had some of my rational detective self left, but the moment I caught the scent of his cock, my body had started burning hotter and hotter… until I finally lost all reason and became a shameless bitch craving my assistant’s cock—the very one I’d secretly adored.
“D-Detective, please come to your senses…”
“Hnn♥ Is this Haru’s cock…? It’s huge♥”
No man could stay unaffected when the detective he served was acting like a bitch. Sure enough, Haru began to react—his crotch swelling noticeably beneath me. I shifted my hips, pressing my pussy against the bulge his cock made, and slowly started grinding against it.
“Hnn… Hnnng♥ Feels good…♥”
“P-please calm down, Detective! You’re not usually like this.”
“Hehe♥ You know what, Assistant? Before they trained me, those guys made me take some kind of drug.”
“A drug…? What kind of drug?”
“They said it turns you into that person’s personal bitch the moment they mark you with their semen♥”
“What? There’s no such thing…”
“There is, though~”
Smiling, I began slowly pulling down Haru’s pants. The “bitch-making drug” was something I’d just made up on the spot, but since Haru hadn’t left any detailed setting about the drug either, I figured it was fine to interpret it this way. It was a bit of an abrupt leap, but I trusted Haru to be generous about it. After all, he was the one who’d turned me into this in the first place—so he had no right to complain if I pounced on him in return. The Haru who was a trainer for a criminal organization and the Haru who was a detective’s assistant were different, but such minor details didn’t matter to me at all.
“And you know what? The only person who’s ever marked me with semen is you, my dear assistant.”
“Huh? Then the fact that I violated you earlier…”
“That’s right♥ So you’ll have to take responsibility for turning me into your personal bitch, won’t you?”
Once I’d stripped off even his underwear, his massive cock sprang out like a coiled spring. The sight of it standing stiff and twitching made my heart race. What was this? I was only roleplaying as a fallen detective bitch to reach the ending I wanted… but the moment I saw Haru’s cock, my whole body grew hot and my lower belly started throbbing. It really felt like I’d become a bitch marked by Haru’s cock…♥
“Our Haru’s cock got bigger too…♥”
“D-Detective…”
“Then I’m going to taste it now♥”
I carefully stroked Haru’s cock while hesitating. With my mouth? Or with my pussy…? In the end, I decided to take it with the pussy that hadn’t even properly received it yet. I lifted my hips, aligned my entrance with his cock, and slowly lowered myself until just the head slipped inside.
“Kuh… Detective.”
“How does it feel to be fucked by my pussy? Haru♥”
“Th-there’s no way it feels good. You’re not doing this because you want to either…”
“I am doing it because I want to, though…♥”
“What?”
I’d expected Haru to lose control and pin me down by now, but he was holding out far longer than I thought. I’d assumed he’d pretend to care for me before suddenly flipping the script, yet he wasn’t taking the bait at all. Fine, then. I smiled at him with as much affection as I could muster and spoke.
“Anyway, since those guys injected that drug into me, I’m definitely broken now, Haru…”
“D-Detective…”
“If you hadn’t come to save me, I’d probably be spreading my legs in front of them right now, begging for cock.”
I pretended my rationality had partially returned, gazing at Haru with slightly teary eyes.
“I’m so happy I can become the bitch of the person I love…♥”
“Detective…”
It was a confession with quite a few screws loose, but I thought it wasn’t a bad line for this situation. It even had a touch of pure love to it. Haru seemed to like the line too—he gave me a faint, almost imperceptible smile.
“Then I’ll help you as much as I can, Detective…!”
He grabbed my waist and yanked me down.
“Hnnng…♥ S-suddenly like that…!”
“Is my cock okay? Does it feel good?”
“Hnn♥ G-good… Haru’s cock♥”
Haru’s massive cock suddenly thrust deep, scraping hard against my inner walls, and my pussy began to tremble as if convulsing. Being penetrated so abruptly while in cowgirl position sent an indescribable wave of pleasure crashing through my head. It felt like I’d been teasing Haru at my own pace, only to be forcibly impaled. Every time he bucked his hips and slammed his cock all the way to the root, vulgar moans spilled from my mouth on their own.
“Hnn♥ Haang♥ It’s stabbing so deep into my pussy… Hek♥ My mind’s going blank♥”
“Are you alright, Detective…?”
“Uheung…♥ I-I’m fine, so… Hnn♥ Do whatever you want, Haru…♥”
“B-but still…”
Haru hesitated with a flustered expression, yet he never stopped bucking his hips. I could tell exactly what he wanted. If I wanted stronger pleasure, I had to beg more desperately. Now that I understood his intention, there was no reason for me—a vulgar bitch—to hesitate.
“I’m Haru’s… Hnn♥ bitch, after all… Haang♥ From now on, don’t treat me like a detective… Heut♥ Treat me like a female…♥”
“Detective…”
“If you… Hnn♥ treat me like a real bitch… Heung♥ I’ll be able to relax quickly too…♥”
“Understood, Detective…”
After I desperately begged to be treated like a bitch, Haru finally nodded. So that had been the right answer. Just how would my dear assistant treat a vulgar bitch? If it was the usual Haru who couldn’t resist puppies, he’d surely treat me gently, right? I’d hoped that now that things had come to this, the soft-hearted assistant who couldn’t even scold me properly would carefully mount me—but instead…
“How about we change positions first? You bitch.”
“Hnn…?”
Our assistant was surprisingly good at acting. Haru’s hands forced me onto all fours on the bed, and he came up behind me before roughly shoving his cock into my pussy.
“Hkk…♥ W-wait a second, Assistant…?”
“Why is a bitch so arrogantly climbing on top of her master and shaking her hips?”
“Th-that’s… Hiit♥”
—Smack
Haru’s hand struck my right buttock hard. Startled by the intense mix of pain and pleasure, I instinctively tried to escape his grip. He held my waist firmly so I couldn’t get away, then spanked me again.
—Smack
“Hkkk…♥”
“If you’re a bitch, shouldn’t you stay still on all fours and wag your tail?”
“S-sorry… I was bwad, Haru…”
“Again.”
—Smack
When Haru’s hand struck my butt once more, I immediately realized what I’d done wrong.
“Haaang♥ I-I was wrong… Please forgive me… Master♥”
“Good. I’ll forgive you.”
“Th-thank you, Master♥”
“As proof of forgiveness, I’m going to cum inside you once. That’s fine, right?”
“Yesh, Master♥ Please mark this vulgar bitch’s pussy thoroughly with your semen♥”
“Alright, then…”
Haru grabbed my waist tightly with the same hand that had been spanking me.
“I’ll mark Jisu’s pussy with my semen.”
He drove his massive cock deep into my pussy.
“Hkkk…♥ Your huge cock all at once…♥”
“How is it, Jisu? Feels good getting pounded by cock all at once, doesn’t it?”
“G-good♥ Getting stabbed so deep by your cock…♥ Hegut♥”
“Moaning like that while getting mounted by someone who was your assistant until recently.”
“Hnn♥ Heu…”
“So Jisu was a natural-born bitch.”
Haru’s cock kept pounding against my cervix, his gentle voice melted my ears, and his sharp scolding completely dissolved both my body and mind. This wasn’t supposed to happen… A proud detective like me, reduced to a bitch who surrendered to her assistant’s cock. Something like that could never…
“Hiit♥ Th-that’s right…! I’m a vulgar bitch who doesn’t deserve to be a detective…♥”
Of course it could. My body had already learned the joy of being female through training. And now that I’d been marked by my assistant’s semen on top of that, there was no way I could ever return to being a detective instead of a bitch.
“Vulgar bitch. To think I once served someone like you as my detective.”
“Hek♥ I-I’m sowwy… Hkk♥ I’m sorry for making you serve a vulgar detective♥”
“Since you’re a vulgar bitch now, you’ll have to serve me as your master instead.”
“Hnn♥ O-of course…! Ang♥ Thank you… for becoming the master of this vulgar bitch… Hnn♥”
“Good. Then as your master, I should mark your bitch pussy with my semen.”
“Yesh…♥ Hnn…! Please mark me with your semen quickly♥”
“I’m going to cum inside your pussy, so take it properly.”
“Yesh…!”
Even as I was halfway to losing consciousness from Haru’s relentless thrusting, I understood his declaration and nodded frantically. It was an instinctive movement—the bitch’s duty to receive every drop of her master’s semen. Seeming satisfied, Haru let out a pleased laugh, gripped both of my buttocks tightly, and—
—Brrrrrt
“Haaang♥”
—pumped his semen deep inside me. When Haru released my hips and pulled his cock out, I collapsed onto the bed, panting heavily.
‘Haru’s semen is flowing along my walls and into my womb…♥’
While I was drifting in a strange pleasure that made me feel like I might get pregnant with Haru’s child, his voice reached me from far away, buzzing faintly.
“D-Detective… Are you alright? I went too far, didn’t I… Detective?”
“Ha… Haru…”
“You must be having trouble moving… Should I help you wash up completely?”
Wash up completely. That was the promise Haru and I had made. A suggestion to end the roleplay and return to our usual selves.
“…Yeah. Please.”
After barely managing to nod and answer, I let go of the thread of consciousness that was slipping away and sank into darkness.
***
“So, what happened after that~?”
“When I came to, Haru had already washed me clean and tucked me into bed. So we just fell asleep together like that.”
“Oh my, you must’ve gone crazy~. You actually passed out after going at it that hard~?”
“Yeah… I-I couldn’t help it! Haru was so intense…”
A week later, I met up with Jihye and told her about the event Haru had prepared. Haru had said it was fine to tell Jihye everything, but I felt like recounting the entire play would be too embarrassing, so I toned it down a bit.
“I’m jealous~. I wonder if Hyun will ever show me that kind of forceful side~?”
“What, you two still haven’t done it?”
“Nope~. Hyun’s still too shy, and I’m planning to wait until he’s ready.”
“What do you mean, wait! In times like this, the girl has to take the lead and push hard.”
“I’ve been giving him subtle hints that it’s okay~. But I don’t know if he still doesn’t have feelings for me or what~.”
“Guys are all dense, so they won’t know until you tell them directly, you know? Our Haru was the same.”
“Really~? From what I’ve heard, it sounded like our Jisu was always the one being pushed down~.”
“Th-that’s… because I raised our Haru so well…”
“Hmm~. I should tell Haru later~.”
“D-don’t tell him!”
When I frantically waved my hands, Jihye laughed as if she found it amusing. Using “telling Haru” as blackmail…! Since Jihye and Haru had been close since high school, I was genuinely scared she might actually do it. If she really told Haru everything I’d said, he’d come find me and say…
“Who raised who? I’ll have to properly show you who’s on top today.”
Then he’d definitely pin me down and go wild. …That wouldn’t be so bad, actually? I should’ve just told him to say it.
“A-anyway, you two hurry up and do it so you can bring me some stories! It’s boring when I’m the only one talking.”
“Got it~. But at this rate, we’ll probably have to wait until our winter trip to find an opportunity~.”
“You think so…? Then we really need to prepare properly for this trip!”
“Right~. Haa… If it weren’t for final exam prep, I could’ve just gone on a trip with our Hyun~.”
“Final exam prep? Why are you already studying for exams?”
I was surprised to hear her talk about exam prep already—we weren’t high school students anymore. Wasn’t the exam still a long way off? As far as I remembered, it was a month away…
“Huh? You guys take your exams late? They’re usually in early December~.”
“R-really?”
“Yeah~. My first exam is on the second Monday of December~.”
“Wh-when was mine again?”
I hurriedly turned on my phone and checked the exam dates. The first Wednesday of December. The final exam for the liberal arts class that taught how to write reports and papers was my first test. I’d complained about why they were giving an exam so early for a liberal arts subject, but I’d completely forgotten while I was distracted by the event Haru was preparing. It was now the fourth week of November—roughly one week left.
“…Th-this is bad!”
“Why~?”
“My exam is in a week.”
“What??”
