Making Memories in Yuna's Room!
Squish... Squish...
Bounce... Bounce...
The deliciously soft texture that I could knead all day without ever growing tired of it.
Groping her secretly right beside Yuna's father gave it an extra thrill of danger.
Her dad stood on Yuna's left side.

Since I kept fondling her right ass cheek, he probably couldn't see it clearly. Even so, Yuna and I were facing each other at such close range that her father began to sense something was off.
I continued silently massaging her plump rear until he finally gave up and headed to the living room to watch TV.
We stayed standing there for a long while, indulging in the intimate skinship.
Smack!
"Eut♡!"
The moment I slapped her ass, Yuna's father glanced our way. We casually walked off as if nothing had happened, and he must have decided the sound hadn't come from here because he turned back to the TV.
I stroked near her pussy before grabbing a handful of her breast.
"Why aren't you wearing the headband like I told you?"
"If I wore that... my family might get suspicious, Master♡..."
Yuna quickly moved her feet, practically dragging me into her room.
She closed the door haphazardly and I pulled out my cock.
"Hiiik!... Hic!... "
The moment it sprang free from my pants, the tip poked firmly into Yuna's belly. Every time she saw my growing erection, she reacted with genuine shock.
Long time no see. You saw it last time too, didn't you?
My cock twitched as if greeting her face directly.
Enough foreplay. I grabbed the ass I'd been kneading earlier, spun her around to face the desk, peeled off the bandage covering her pussy, and shoved my dick straight inside.
Shllluuurp!
"Ughuut♡... We can't... do it here, Master♡..."
Even as she drooled and protested, I gripped her hips and adjusted her into the perfect position for fucking.
I made her press her head against the desk and thrust her ass out.
Pah♡! Pah♡! Pah♡! Pah♡! Pah♡!
"Ahuk♡! Uk! Uup♡! Uup! Uup♡!"
The sudden piston thrusts drew out her moans, but she quickly clamped both hands over her mouth in fear her father would hear.
Slap!
"Uuuup♡! Uup! Uup! Uup♡!"
Regardless, the crisp sound of my palm striking her ass was absolutely exquisite.
"...Is everything okay in there?"
"Ah~ We're just playing some games before doing homework!"
I answered in Yuna's place while she kept her mouth sealed shut.
"Hmm... I-I see... Have fun then..."
Her father, who had rushed to the door after sensing something strange, eased his suspicion at the mention of games and walked away.
It really was a fun game. A game of fucking the daughter while the whole family was home!
Despite Yuna claiming we couldn't do this at her house, her pussy clung to me like it was kissing my cock, squeezing with desperate greed. Every time I pulled back, her inner folds stretched out lewdly, yanking her head backward.
Her pussy had loosened up quite a bit by now. Its shape had molded perfectly to my cock. Any smaller man would probably feel like he was stirring empty air.
She twisted and writhed in pain even though I hadn't put it all the way in yet. As I gradually pushed deeper, her face slowly filled with terror.
"Yuna, it looks like you've become a proper ruined pussy now, huh?"
Tears began to well up in Yuna's eyes. She must have realized how loose her cunt had become after taking my cock so many times.
"Squeeze me properly!"
Slap!
"Uup♡!"
Honestly there was no problem at all with her gripping my massive cock, but the moment I spanked her, her pussy tightened another level.
"Kgh... I'm cumming! Take it all this time without spilling any!"
"...Uup♡! Uuup! Uuup♡!"
Spurt! Spurtt! Spluuuurrrt! Spluuuurk! Splurt! Spurt!
Her already-full womb and pussy swelled up as they accepted my load.
When I pulled my cock out, a wet plop sounded as her pussy lips clung stubbornly to me. Thick semen dripped from Yuna's cunt onto the floor, forming sticky strings. It also coated her thighs like spiderwebs.
I stuck the bandage back on, sat at the desk, and ordered Yuna to clean me.
She crawled under the desk, took my cock into her mouth, and began moving.
"Yuna, you didn't follow what I told you to do... You need to be punished, don't you?"
With my cock still in her mouth, Yuna nodded quietly.
"Then keep cleaning for now."
Yuna began earnestly servicing me, forcing my cock to the root again and again while lavishing it with her tongue.
"Ughk♡... Uk... Huuk♡!... Uuk... Huuk♡!... Ubuup... Huuk♡!"
She still loved smelling my cock. I spotted some paper nearby, picked up a pen, and began jotting down a few things.
I was planning to use the Physical Contract Seal I'd obtained last time. There was also knowledge that had naturally entered my head when I gained the trait.
Hmm... Should I set it so Yuna cannot wear anything except the clothes I designate for her?
She could perform actions that broke the rules, but she could not refuse to perform actions that were required. For that, penalties needed to be defined. I'd add penalties related to her everyday clothing!
This way I could punish her directly however I wanted. It was surprisingly fun once I started thinking about it.
For starters, ban panties. Skirt length 20cm or less. Tops must be crop tops that show the underside of her breasts. She must not hide her tail. The headband looks pretty whether she's wearing it or not, so I'll leave that alone.
She cannot erase the scribbles I make on her by herself. She cannot change the clothing I designate without permission. When I visit the house, she must open the door anytime and cannot refuse me no matter where or what I want to do. If she changes her password or moves house, she must inform me. That should be enough for now!
Yuna was sucking so eagerly that I felt another load coming. I clamped my thighs around her head, pressing her face tightly against my crotch with my legs.
Spurt! Spurt! Spurt! Spurt!
My thick semen poured straight down Yuna's throat.
"Gulp...♡! Gulp....♡! Gulp...♡! Gulp...♡!"
She swallowed my cum with far more difficulty than before. When I pulled out, the viscous semen clung to her throat and refused to go down.
I looked at Yuna, who kept her mouth wide open, and spat.
"Mmm... Ptoo!"
My spit landed accurately on the semen, but it still hadn't all gone down.
"Ptoo!... Ptoo!... Ptoo!"
After several more spits, the semen clogging her throat slid cleanly into her stomach.
Wait... If I do this, my cum will come back up from her mouth...
Let's write the contract first!
"Yuna, come up here and read this!"
"...? Yes, Master♡!"
Yuna read the contract several times before asking with a terrified expression.
"This♡... Why do I have to write this...♡?"
She looked so good like this.
"Are you rebelling against me right now?"
"Ah... No... That's not it..."
"This is your punishment for not wearing the headband."
".......Ah... I understand, Master♡."
She had become so obedient lately that she accepted the unfair contract I suddenly thrust at her.
Fortunately, the Physical Contract Seal only required the other party's consent. The actual method of completing the contract, however, was quite unique.
Physical Contract Seal
Mana Cost: 666/700
I activated the trait. The moment 666 mana drained out of my 700 total, dizziness washed over me. I steadied myself, completely lifted the skirt hiding her ass, then activated Body Temperature Regulation to heat my cock to a scorching temperature.
I pressed my cock—now covered in the bumpy, brand-like pattern of the activated seal—firmly against Yuna's ass.
"Kwaaaaaaaaagh! Uwaaaaaagh! It's hooooooot!"
Yuna foamed at the mouth and rolled her eyes back. She thrashed wildly, screaming in agony.
"Get a hold of yourself! Be quiet!"
The seal was still being engraved on her ass. If her father heard those screams, he would come running!
Clatter!
Her father burst through the door after hearing her scream.
"What happened?! Are you okay?"
"Uuuuugh♡! It's! The game character! Diiiiied♡!"
Luckily I was behind Yuna, pressing my cock against her to finish engraving the seal.

He probably couldn't tell that my cock was out or that it was directly touching her ass. Yuna seemed to have made an appropriate excuse.
While I kept my hips glued to her ass, her father's eyes looked filled with rage, but he appeared somewhat relieved after hearing she wasn't hurt.
Her father spoke in a trembling voice.
"Yuna... Aren't you... a bit too close to that boy? Your boyfriend might get worried..."
"It's fiiiiine♡! Don't mind usssss! Get ouuuut♡! I said get out!"
"What...? Y-Yuna... Why are you speaking like..."
"Get ouuuut! I don't want to hear it so get ouuuut!"
"..........."
Her father looked devastated by her words and left with a complicated expression. He must have been shocked to see his daughter like this.
A wailing daughter, a man gripping her ass and thrusting his pelvis against it, and the daughter telling him to leave and stop worrying about her. He was probably confused whether he was misunderstanding or if she was simply being too sensitive.
I had applied Confusion with my pheromones, but the sound of flesh slapping, her moans, the scream just now, and her completely changed attitude must have been overwhelming. Yuna had truly become a terrible daughter.
I pulled my cock away from her ass to check the seal. The word Fuckhole was clearly engraved in vivid red exactly as I intended.
Click!
I took a satisfied photo of the beautifully branded mark.
"...Uut♡... It hurts..."
I shoved my still-burning cock back into Yuna's pussy.
"Kyaaaah♡!..."
I didn't move like before. The pain from the brand seemed severe.
As expected, nothing beats a pussy injection for pain relief.
I injected the yellow anesthetic liquid.
Shhhhhhhhhhh....
"H-Hot♡... You're crazy... This can't be♡!"
My urine poured into Yuna's pussy. The stream gradually thickened, changing the sound it made. It sounded like a showerhead or a hose!
Yuna was overwhelmed with unbelievable humiliation and shame at being treated like a toy, her pussy used as a toilet.
"Huuuugh..♡! I'm not a toilet..♡! Mom and Dad didn't give birth to me to become a toilet..♡!"
Tears of shame flowed from Yuna's eyes. Her pussy swelled more and more until her belly looked like that of a pregnant woman.
I stopped the flow, sealed her pussy with the bandage again, then grabbed the pitiful Yuna by the waist and laid her on the bed.
Before filling her mouth with fresh semen, I sat on her face.
I rubbed my cock and balls all over her face again, just like last time, marking her once more with my scent.
"Kuuup♡! Haa♡! Kuuuuup♡! Huaaaa♡!"
Yuna desperately inhaled the filthy smell of my cock.
My pubic hair now clung sparsely to her face.
"You're not a toilet... You're my personal bidet! So lick here too."
The realization that she was still being treated like bathroom furniture made the tears in Yuna's eyes refuse to stop.
I positioned my asshole over her mouth.
Yuna grimaced but lightly touched it with the tip of her tongue.
Lick♡... Lick♡....
She seemed to find the hole itself difficult at first and licked around it, but once she got used to it, she extended her tongue further and began pushing the tip inside little by little.
I continued grinding my cock and balls against her face.
The tongue that had been cautiously licking my ass juices gradually went deeper.
"Ebup♡... Ebup♡... Ep.... Ebuuup♡... Ebuuup♡....!"
Spurt! Psst! Pssshhhhhh!
Yuna's legs thrashed wildly as female juices gushed from her pussy, soaking the bed.
After warming my cock on her face, I stood up from her lying form, aimed at her open mouth, and began to piss.
Shhhhhhhhhhh!
Most of it went into her mouth, but some splashed off due to the height and landed on her pillow. My urine soaked Yuna's face, clothes, and hair. The smell of my piss especially permeated her bed.
Gulp♡! Gulp♡! Gulp♡!
Yuna, who desperately didn't want to dirty her own room, swallowed the urine as fast as she could. Her stomach swelled even more as it filled with piss and semen, making her look like she was at full term.
I shook out the last drops, put my cock away, then put a mask on Yuna and ordered her not to remove it since it was now part of her designated outfit. Because the contract stated she could not change her clothing without permission, she could no longer take it off.
I pulled the blanket over her head, then stepped on her swollen belly.
"Uk?! Uup♡! Ubuup♡!"
Pssshhh! Pssshhh! Psst!
Urine and semen leaked from both her pussy and mouth. Although both holes were somewhat sealed, the pressure on her belly forced it out anyway.
It wasn't exactly fucking, but the insane sense of depravity from this perverted act filled me with pleasure.
When I lifted the blanket, I saw the sticky, foul-smelling blanket, the soiled mask, and Yuna's cheeks puffed up again from the urine and semen rising from her stomach.
Whew... Yuna's room was now filled with the smell of my piss and cum...
Time to leave.
"I'm heading out now! Say goodbye to your dad for me!"
This was goodbye with Yuna for a while!
"........♡"
Yuna stared blankly into space with unfocused eyes. It was a short visit, but I had created plenty of pleasurable memories for her.
It was fun! See you when I come back!
