Don't Worry, I'm Signing You to a Lifetime Contract♡
Squish. Squish.
"Eek, oh-ah♡ Mmm-ghh♡ Hah, ghh♡ Oh!!♡"
Every time the boss’s fingers churned inside my anal, a pleasant, invasive sensation hammered straight into my brain. It was definitely strange to feel fingers sliding in and out of my rear, yet my body was betraying me, crying out that it felt good, spilling out pre-cum along with the semen already shot deep inside me.
"You’re so lewd, Jian. Even though it’s your first time, you’re feeling it this much?♡"
"H-heugh, mmm-ghhh!!♡ Hah♡ Boss, it’s…♡"
Things like this shouldn't feel good. I shouldn't be some pervert who gets off on a hole made for excretion. But my body was so incredibly lascivious that even this feeling of intrusion had been twisted into pure pleasure.
"Ghh-nnngh♡ Hah♡ Mmm-ghhh, ghh-ohhh!!♡"
Pshhhhhhh—!!
In the end, not long after being probed by her fingers, my body arched back, vomiting out a flood of fluids.
"Hah, hah……♡"
To think I’d spill this much just from a few fingers. I couldn't even fathom how much more depraved my body could become. At this rate, I might really turn into a hopeless female who feels pleasure in every single hole… yet, for some reason, I didn't hate it at all.
"Fufu…. If you’re like this now, I wonder how much you’ll feel when I actually slide my cock in, Jian.♡"
"I, I don’t kno-ow…♡"
"If you don’t know, I guess I’ll just have to teach you myself.♡"
Squelch.
The boss pressed her glans against my anal opening, which had been rendered slick and loose by her fingers, and began to grind.
"Hgh♡ Ah!!♡ H-heugh, mmm!!♡"
It was hard to believe this was my first time; every time her glans rubbed against my entrance, lewd, shameless moans poured from my lips. This wasn't right—it shouldn't feel this good. If I kept this up, I’d inevitably fall from a part-timer to the boss’s personal biological onahole.
I didn't know anymore. My brain wasn't functioning. The only thought in my head right now was… the desperate desire to take the boss’s cock into my anal cavity and feel that pleasure. No other thoughts could find purchase.
"Boss, Bo-oss♡"
"Hm? What is it, my dear Jian?"
"Stop, stop teasing me♡ Cock, please put your cock in♡ Please, put your cock in my anal hole…♡"
My mind was so hazy that I just blurted out whatever came to mind.
"Fu-hun……♡"
The boss gave a satisfied smile at my words, grabbed my legs firmly, and thrust her cock straight into my anal cavity.
Squelch-thwuck—!!

"Ghh-eeeeek!?♡♡"
> Your Female Potency has increased significantly.
> Pain from penetration is now converted into Pleasure.
With the message came a wave of distant, overwhelming pleasure, and my waist arched like a bow on its own. It was a completely different kind of pleasure compared to my vagina, yet it was more than enough to drive me to climax.
"Hah, hah♡ Ghh♡ Oh-oh…♡"
"Ah……♡ Jian, your anal hole is a passing grade, too.♡"
The boss shuddered with pleasure. At the same time, her cock twitched inside me, pumping out pre-cum in thick, rhythmic bursts. She seemed truly, deeply satisfied with my anal cavity.
"Boss, it’s…♡ Are you, gh-h… satisfied?♡"
"Of course. I’m so glad I managed to hire a part-timer like you, Jian.♡"
"Ehe, hehehe♡"
I couldn't help but smile at her words. Being favored by such a beautiful boss made me feel so good.
"I’m, so glad♡"
"Does it hurt at all?"
"No…♡ It doesn’t, mmm!♡ Hurt at all, Boss♡"
Was the system message really true? Everything I’d read online said that anal sex was just as painful as a first-time vaginal experience… yet even with her massive cock buried inside me, I felt no pain, only pure, unadulterated pleasure.
"Fufu…♡ That’s a relief. Usually, people hurt too much and make me pull out."
"I’m fine, hgh!?♡ I’m fine, Boss♡"
"Is that so? Then… I’ll have to fill your anal hole up plenty, just like your vagina, and make you love my cock.♡"
Squelch—
"Ghh-ohhhhh!?♡"
As she finished speaking, the boss slowly began to withdraw her cock. The pleasure of that thick shaft scraping against my internal walls made my waist thrash. My mind went completely blank, white as a sheet, unable to hold a single thought.
Could any female endure this? I could swear that none could. If any female felt this sensation of her cock sliding out of her anal cavity… she would inevitably be unable to resist, climaxing at every single moment just like me. That was how distant and overwhelming this pleasure was.
"Heugh, oh-oh♡ Bo-oss♡ Ghh♡ I can’t, endure this♡ Mmm-ohhh!!!♡"
Even though my tongue was limp from the pleasure and I couldn't form proper words, I begged her desperately. But despite my earnest pleas, the boss didn't seem to care at all as she continued to pull out.
"Mmm-ghh-eeeek!!♡ Ghh, gh-ohh♡ Oh-go-oh!!♡"
"It’s okay, it’s okay♡ You’re a wonderful female, Jian, so you can endure this too.♡"
Because her cock was so long, the pleasure simply wouldn't stop. *'W-when does this end, hah♡'* I felt like I was going to lose my mind. Just as my consciousness, which had been flickering, was about to snap entirely, the sensation of her cock withdrawing finally stopped. She had pulled it out to the very root.
"Fuuu……♡ Your anal hole is so good, Jian, I almost came just from pulling out.♡"
The boss exhaled a ragged breath and looked into my eyes.
"Oh, oh-ohhh♡ Oh!!♡"
"But I can’t end it after just one round with an anal hole like this.♡"
After catching her breath for a moment, the boss tensed her waist. If she thrust in now, I was certain I’d break. Before I could even stop her, she put her full weight into it and drove her cock straight down into my anal cavity.
Squelch-thwuck-thwuck-thwuck!!
"———᧗ʃᖍ❤?!!!!!"
A moan that couldn't even be called a scream tore from my throat. My body trembled uncontrollably, as if electrocuted. A pleasure that felt like it was melting my brain, not just breaking it, washed over me every single second. How could my body possibly hold up?
"Ghh-eeeek♡ Oh, oh-oh♡ Hoh-ohhh!!♡"
Psh! Pshhhhhhh!!
Perhaps I’d run out of lubrication, but a stream of pale yellow urine poured from my vagina, soaking the boss’s lower abdomen. Even so, the boss didn't seem to mind. She repeated the motion, slowly withdrawing and then thrusting in with a single, powerful movement.
Squelch— Thwuck!! Squelch—! Thwuck!!
"Ugh-gh-eeeek♡ Ghh-ohhhhh!! Oh-oh-oh♡ Mmm-ghhh!!♡"
"Mmm-ghh♡ I love how your anal hole tightens so well every time I thrust, Jian.♡"
The boss pulled me into a tight embrace, as if to tell me not to even think about running away. Thanks to that, there was nothing I could do. All I could do was let out obscene moans in her arms and climax, over and over again.
"Boss, oh-oh!!♡ Bo-oss, your anal…♡ Ghh♡ It feels so good, I think I’m going to die♡"
"Fufu, don’t worry♡ I’m signing you to a lifetime contract, so we’ll be together until we die.♡"
"Hah-eeeek!!♡"
It seemed the boss would never let me go. Did this mean I had to live as the boss’s exclusive vagina from now on?
> Your Female Potency is continuously increasing.
"I-it’s, good, hah♡"
It was good. To live as the cock-case for such a beautiful boss… I couldn't possibly hate a job where I could earn money and feel this good.
"It’s good, Boss♡ Oh-oh♡ I, I want to become your full-time employee, Boss♡"
"Good, good♡ Since Jian has agreed, I’ll have to have you stamp the contract with your cum-seal.♡"
Thwuck-thwuck-thwuck!!
Along with her increasingly rough thrusts, the boss’s cock began to twitch. I realized this was the signal that she was about to ejaculate, so I tightened my muscles and squeezed her cock with everything I had.
"Ugh?♡ Jian♡ Are you acting this cute just because you became a full-time employee?"
"Yes♡ Hgh!♡ I’ll keep making your cock feel good, Boss♡"
"Oh my♡ If you keep acting so cute, I won’t be able to… hold back.♡ Oh-oh♡"
Unable to hold back the urge to ejaculate, the boss shoved her cock to the very root inside my anal cavity.
"Jian, I’m cumming♡ I have to stamp the lifetime contract, hgh♡"
And the moment her words ended.

Splurt-splurt-splurt!! Splub-bub-bub-bub-splut!! Splurt, splurt-ghhh!! Splurt!!
The boss’s semen began to pour into my bowels, filling them to the brim.
"Hah-eeeek!♡ Mmm-ghh, ugh-gh, oh-oh-oh——᧗ʃᖍ❤!!"
The sensation of that sticky, lava-hot semen filling my anal cavity… my body couldn't possibly endure such pleasure. My body reacted automatically, reflexively pouring out a fresh flood of fluids from my vagina.
"Ugh-hit, ugh-oh♡ Oh-oh-oh♡"
Splurt, splub-bub-bub! Splurt!!
"Fuu-hah, hah-ah♡ Your anal hole tightens so much, Jian, so much cum is coming out……♡"
My stomach had returned to normal after the previous sex as the semen drained out, but thanks to the boss’s massive volume, my belly was restored to the size of a pregnant woman’s once more. It was a volume that rivaled my mother’s. I naturally wondered if my mother would have ejaculated this much if she hadn't been trying to be considerate of me.

"Hah, hah……♡"
Only after a long time did the boss’s ejaculation finally come to an end.
Pop!
As soon as she finished, the boss’s cock pulled out with a sound like a bottle cork being popped. She brought the cock, still dripping with the semen she’d just shot, to my lips and said:
"There now, Jian♡ The contract is signed, so now it’s time for your signature♡ By giving my cock a kiss.♡"
