Police Uniform Ravishment and Lactation Upgrade
I started pounding mercilessly into Lee Yoo-jin at home, her I-cup office worker body looking so obscenely slutty. She welcomed my cock by shaking her hips wildly, and after repeating those rough thrusts a few times, she buried her face in the bed and gasped out to me as the waves of pleasure crashed over her.
"Hahk! Master, you're too rough!"
"Shut up."
Slap!
No matter what she said, I kept slamming into her fiercely, slapping my palm down on her plump, jiggling ass to tease her more. Unable to hold back the surging ecstasy, she climaxed right then and there.
"Ahhh! I'm cumming... Master, I... Aaaah!"
Squiiiirt!
Maybe fantasizing about being violated by a criminal while dressed as a cop, Yoo-jin squirted harder than ever, her bound fingers twitching in the handcuffs as she came. I kept my pace steady, slapping the other cheek instead of the already red one.
Smack!
"Haah! M-Master... p-please, just a little break..."
Even after cumming, the nonstop pleasure made her tongue go limp, and she begged me with a deflating whimper. The special thrill of her being tied up pushed my arousal to the brink, so with the intent to really knock her up, I aimed my tip precisely at her womb and unleashed.
Spurt, spurt, spurt!
"Get pregnant!"
"Heek! Haaahng..."
I kept moving through my orgasm, pressing my tip tight against her womb like I meant it. Unlike before, Yoo-jin took the ferocious barrage of semen head-on, burying her face in the pillow as her bent knees straightened out, her body trembling like a newborn fawn trying to stand. She came again.
That was the most intense pleasure I'd ever felt during sex. Once I'd emptied everything, I pulled my cock out of her pussy. Her lower body, which had been propped up only by it, collapsed onto the bed with a thud, and she panted raggedly.
"Hee... Hweee..."
Feeling sorry for Yoo-jin heaving face-down on the bed, I unlocked the handcuffs from her arms, freeing her. I flipped her over—she was still lost in the afterglow—and decided to do what I'd been wanting to try next time I saw her.
Activate Mutant Semen.
Mutant Semen skill activated.
Current modifiable opposite sex: Yoo-jin (LV.2)
A notification popped up with the skill activation, followed by a huge list. Next to it showed the amount of semen I'd ejaculated into Yoo-jin.
I came a ton.
Even though I hadn't cum that many times, the sheer volume—leagues beyond any normal guy's—made me feel superior as I picked what to modify.
Semen required for lactation modification: 500ml.
Proceed?
Yes.
Applied successfully.
If unsatisfied with the modification, use 100ml of semen to revert.
Damn...
I'd thought my choice was perfect, but it could even revert? I scanned the list for more options applicable to Yoo-jin: stamina boost, fatigue recovery, wound healing, scar removal, fat reduction, body reshaping, and tons more. To keep fucking nonstop all weekend without her tiring out, I selected stamina boost and fatigue recovery.
Fatigue Recovery - 100ml
Stamina Boost - 300ml
Proceed?
Less than lactation but still impossible for a normal guy. Grateful for my Evolved Body, I confirmed.
Applied successfully.
No numerical stats showed how much they'd improved, so I was curious. Yoo-jin's breathing had finally steadied, so I asked her.
"How's your body feeling?"
"My body? Uh...?"
Hearing me, Yoo-jin blinked in surprise. After two weeks of endless overtime, her heavy fatigue vanished into a refreshing lightness, and her aching shoulders—from lugging those massive tits—felt at ease. She stared at me wide-eyed.
"It feels super light!"
The skills apply instantly, huh.
"Did you do this for me, Master?"
Anyone else might've just thought they'd slept it off, but with fatigue piled up from nonstop overtime suddenly gone, she immediately suspected me. I couldn't exactly say I used my skills, so after pondering, I claimed I'd massaged her while she was out.
"You looked exhausted, so I gave you a massage while you were lying there."
"Thank you so much, Master! I feel like I could fly."
She sat up on the bed, flexing her arms to savor her lighter shoulders, then stood and pushed me down onto the bed.
"Let me service you now, Master, for massaging me."
With that, Yoo-jin untied the knot on her police uniform, spread her cleavage with both hands, and engulfed my raging erection between her tits.
"Wow... Master's cock is really huge."
No guy she'd titfucked before had ever poked out, but even buried in her massive breasts, my tip protruded. She gasped in awe.
"If it doesn't stick out in tits this big, you're no real man."
"You're right... Hngh."
Unlike the weaklings she'd known, this true alpha male made her womb heat up. She drooled saliva into her cleavage, squeezed her tits tight with her arms, and started sliding them up and down gently.
"Ngh..."
I'd seen paizuri in porn plenty, but figured it'd never beat pussy. I was wrong—time to reflect.
Tits this big give a whole different pleasure from pussy!
No tight grips or wrinkles massaging every inch like a pussy, but with lube from her juices and spit making it slick, her soft yet elastic tits enveloped me completely. The hydraulic pressure—like they could hug anything—felt incredible.
Yoo-jin skillfully varied the pace, sliding her tits up and down. When my thighs started trembling sooner than expected, her confidence surged, and she stuck out her tongue to lick the exposed tip.
"Guh!"
Already lost in the plush, firm tit bliss, the sudden slick, rough tongue on my glans sent a surprise jolt through me. My hips bucked up.
"Hm?"
With her mouth open and tongue out, she slurped the incoming tip, swirling her tongue wildly. Feeling it twitch in her cleavage, she licked harder and pumped faster—until the explosive cumshot overwhelmed her. She pulled back, and ropes shot toward the ceiling.
"Cumming!"
"Kyaa!"
As she detached, semen splattered her face every which way. To avoid a cum facial, she lifted her tits to trap it all against them.
Spurt! Spuuurt!
"Haa..."
The overwhelming pleasure made me shoot more than usual. My hips went weak, thighs quivering faintly. Yoo-jin, who'd hugged my cock tight with her tits, pulled back, grabbed her nipples, and spread her breasts apart.
"Wah... it's like a semen shower."
Looking down at the webby strands stretching between her cum-coated tits, her face smeared with globs, she murmured.
"Mmm, Master's semen really is on another level."
She scooped the facial globs into her mouth, chewed and swallowed, then slathered the rest over her entire chest like lotion—right in front of me.
"Nngh... Huh?"
Squirt!
As she moaned and smeared, a hot flush hit her tits, and milky white liquid leaked from her nipples. She stared in confusion.
"Why is this...?"
Panicking at this first-time phenomenon, she gawked at her leaking nipples. They were cum-smeared and hot as hell, so I reached down, pinched one between thumb and forefinger, and tugged—like a faucet, milk squirted out in a stream.
"Ahng..."
"Tits like these gotta lactate like a cow."
Still disbelieving as she stared at me questioningly, Yoo-jin said,
"I've never done this in my life."
"With udders that huge, it's about time."
"I've never even been pregnant."
I couldn't reveal my semen-modification skill, so I teased,
"Go see an OB-GYN next time."
"I'll take a sick day Monday and check it out."
With that, she headed to the bathroom to wash off her cum-drenched tits. Watching her go, I activated Lustful Eye.
Does lactation have no limit?
Curious how much milk she could produce, I asked the system. It answered politely.
Body modified, so milk generates infinitely without limit.
So no buildup or anything?
Correct. Milk generates only during pleasure.
Relieved it wouldn't interfere with daily life, I pondered how to conquer Park So-jin before she returned.
