Mother-in-Law? No, Call Me Big Sister!
By stopping the laboratory raid, I finished my two-day service to Seryu Military Company and headed straight for Akita City. Of course, even though I called it a service, it wasn’t free labor. Sawayanagi Azuma had promised to combine the point rewards and give me a cut, after all. It wasn’t a huge sum to me anymore, but investing it elsewhere could easily multiply the returns several times over, so the more money the better.
The reason I was going to Akita City was so I could spend the night there and fly straight out of Akita Airport to Korea the next morning. Staying in Yurihonjo City and then rushing to the airport might make me late, so sleeping near the terminal seemed wiser.
Of course, there were no direct flights from Akita to Korea. The route went through Haneda Airport in Tokyo before continuing to Incheon. Akita Airport mostly handled domestic flights, so there was no helping it.
The trip from Yurihonjo City to Akita City was comfortable. Mimata Chieri had sent a driver, so I simply sat in the back seat and scrolled through my phone. Since it was an ordinary civilian vehicle rather than a PMC one, we didn’t run into any Kurotsukidoo ambushes.
“Hubae-nim, you worked hard these past two days and one night.”
“It wasn’t that difficult.”
When I arrived at the lodging, Mimata Chieri greeted me warmly. The accommodation was a luxury hotel in downtown Akita. She must have seen real combat herself; beneath her usual refreshing body scent lingered the faint, metallic smell of gunpowder. She shrugged and told me the man with the sunglasses had given her a bit of trouble, but it was nothing serious.
“It’s late. Let’s head to the room first.”
“Alright.”
Between the laboratory battle, the cleanup, and the travel time to Akita City, it was already close to bedtime. I entered the room Mimata Chieri had reserved. She followed me inside as if it were the most natural thing in the world.
“Ah, by the way, I heard the group of attackers you captured managed to escape.”
“They what?”
I had left them completely incapacitated and even used prototype restraints designed to seal ability users’ powers during transport. How could they have escaped?
“Could you explain in more detail?”
“It looks like they had outside help. The entire escort unit was wiped out, and all the prisoners vanished. The black box footage showed they were attacked. However…”
“However?”
Why did she have to stop right there and leave me hanging?
“The strange part is that very few people knew Nagumo Shian had sent reinforcements to the laboratory. And even fewer knew the prisoners were being transported to Daisen.”
“So the information leaked from inside.”
“Yes.”
That meant one of two things. Either there was a traitor among Taira Food’s upper ranks, or the laboratory had been under constant surveillance. Since ambushing the transport to steal the prisoners would be far riskier than simply joining the fight at the lab itself, I found myself leaning toward the first possibility.
“You and East Weapon should operate with extra caution. There’s a chance information is leaking from Taira Food’s side as well.”
“Of course. Hehe. Our mission is simply to hold the line, so it’s actually quite easy.”
The current war situation had Akita City in the west and Senboku City in the east forming the defensive line. North of that was Kurotsukidoo’s sphere of influence, while south of it—except for Yurihonjo City—fell under Taira Food’s control.
Looking at the board, if Seryu Military Company fully recaptured Yurihonjo City, we would earn considerable merit. Naturally, if East Weapon successfully defended Akita City, they would earn their share of the credit as well.
“Enough shop talk. Shall we wash up?”
“Yes. Shall we bathe together?”
I wrapped an arm around the waist of the eagerly suggestive Mimata Chieri and headed for the bathroom. Thoughtfully, the tub was already filled with warm water. Being a high-end suite, the bathtub was luxuriously spacious.
We took a quick shower first, then slipped into the tub. Although it was wide, I sat down first and let Mimata Chieri settle on top of me.
Despite her slender frame, she was slightly heavier than she looked—probably the result of her biological modifications. Her muscle density was far higher than appearances suggested, which made her weigh more than expected. Still, with my own enhanced strength, she felt light as a feather.
“Hehe, I drew the warm water ahead of time. Did I do well?”
“Yes, it feels wonderful.”
I stroked her damp hair as I spoke. Mimata Chieri remained perfectly still, like a cat being scratched under the chin, simply enjoying the sensation of my hand. After a while, my fingers drifted from her hair down to her smooth shoulders.
Her skin was silky. After caressing her shoulders a few times, I cupped her perfectly sized breasts, which floated half-submerged in the water.
“Hngh…! I must be extra sensitive today because I killed people.”
She probably meant her senses were heightened from the intense focus of battle. I gave her nipple a light pinch. After all, I always ended up having sex on days I fought too—the adrenaline demanded it—so her words weren’t wrong.
“Haaang! Yes, I like that, Hubae-nim!”
I had pinched hard enough to hurt, yet she clearly enjoyed it. As expected, Mimata Chieri’s masochistic side was very much present. I played with her breasts freely beneath the water, then slid one hand along her narrow, toned waist until I reached her now-familiar pussy.
“Hyaaah! Hngh♥”
Chup, chup!
I pressed my lips to the nape of her neck and sucked, leaving a clear kiss mark. Since it was hidden beneath her hair, no one would notice unless she deliberately showed it.
“Haan~! If you leave a mark like that, everyone will know I belong to you♥”
“Does that bother you?”
“Hngh! I like it… I love it…!”
She couldn’t think straight under the triple assault on her breasts, pussy, and neck. Eventually she twisted around, captured my mouth, and kissed me fiercely.
Chup♥ Chuuup! Chuuup♥
Feeling her hot breath against my face, I lost myself in the kiss. It was deep, sticky, and passionate. We must have kissed for nearly ten minutes. The bathroom echoed with the wet sounds of our lips devouring each other.
“Stand up for a moment.”
Without questioning why, Mimata Chieri rose. Water cascaded off her body with a splash, placing her firm backside slightly above my eye level.
“Spread your legs and push your hips toward me.”
Obeying at once, she parted her thighs, leaned forward slightly, and presented her ass. Her dainty little pussy hovered right in front of my face. I extended my tongue and licked her slowly, savoring every inch.
“Hngh!! Hubae-nim’s licking feels so good♥”
I thrust my tongue into her entrance, licking and teasing her thoroughly. Less than three minutes later she cried out, “Haaang!” and collapsed into the water with a splash. Her legs had given out from the orgasm.
“Haa… haa… haa… This time, let me please you.”
Still trembling from her climax, she turned, knelt before me, and took my rigid cock into her mouth. She inhaled deeply through her nose, then sank down until I was buried deep in her throat.
Which meant her face was now submerged in the bathwater. I suppose this could be called underwater fellatio.
“Ugh…!”
The sensation was incredible. Earlier, while sitting on me, she had been grinding her soft ass against my cock even as I caressed her, so the urge to cum arrived quickly.
I didn’t bother holding back. I began releasing straight down her throat. The pleasure was exquisite, but I was also worried she might suffocate if she stayed underwater too long, so I came as fast as I could.
Splash!
Mimata Chieri lifted her head from the water, face dripping, and opened her mouth.
“Aah~!”
I had pumped so much that even after swallowing what she could, a large amount remained in her mouth. She showed it to me deliberately, rolling the semen around on her tongue before closing her lips and swallowing with an audible gulp.
The lewd display kept me rock hard, my cock standing straight up like a pillar rising from the water.
“Stand up again.”
“Yes.”
She rose, staring at my erection with lust-filled eyes, then looked at me like an obedient puppy awaiting the next order.
“Aim carefully and sit down.”
“♥”
She kept her gaze locked on mine as she slowly bent her knees. True to her assassin background, her aim was perfect. On the first try, her entrance kissed the head of my cock. I watched with rapt attention as she sank down, my length gradually disappearing inside her.
“Hngh…! It’s so full, Hubae-nim♥”
“It feels amazing how tightly you grip me, Sunbae-nim.”
“Hngh… Please kiss me.”
In this face-to-face sitting position, we embraced and kissed deeply while she began rolling her hips. The water splashed rhythmically around us.
Splash, splash!
At first her movements were slow and teasing, but soon she was slamming herself down hard enough to make waves spill over the edge of the tub. I matched her pace, thrusting upward to meet every descent.
“Hngh, haat!! Ha-eup! Yes, it’s so big! Right there—ahh, I love when you scrape that spot!”
She worked her hips in every direction—up and down, front to back, side to side—showing off an almost hypnotic range of motion.
Mimata Chieri showed no sign of tiring. For nearly thirty minutes she kept riding me, climaxing repeatedly while never slowing her frantic pace. I had already cum once, so the second orgasm took longer to build, but the constant intense stimulation finally pushed me to the edge.
“Ugh! I’m about to cum, Sunbae-nim.”
“Inside, fill me up inside. Please give me your hot baby juice, Hubae-nim♥”
Baby juice? The ridiculous phrasing only made it hotter. Hearing her talk so shamelessly doubled my arousal.
“Kgh, I’m cumming!”
“Haaang!! I’m cumming too! Hngh! Hubae-niiim!!”
Spurt, spurt!!
As I erupted, she slammed down to the hilt and clung to me tightly. Thick semen overflowed from her stuffed pussy and womb, turning the bathwater milky white. Staying in a semen bath any longer felt excessive, so it was time to get out.
“Hngggg…!”
Mimata Chieri was still making strange, breathless noises with her eyes rolled back from the overwhelming orgasm. I lifted her out, rinsed both of us with lukewarm water, dried off roughly, then carried her to the bed in a princess hold.
The night was still young. Of course, I had to fly to Korea tomorrow and she had battles ahead, so I had no intention of overdoing it. One or two more rounds would be enough.
