Filled Full of My Baby Batter ❤
Her insides were overflowing with my baby batter ❤ She wanted me to leave my traces all over her.
Where the hell did a saintess pick up such filthy talk? At this point, I'd straight-up believe it if someone told me her mentor was a succubus.
I really did want to pump her full because of it…
"Um… sis."
"Yeah?"
"I love it, but… I don't really know how to leave marks…"
Elysia sis giggled at my words, then lifted her head slightly and whispered in a soft voice.
"Alright, my sweet Kyle. Sis'll show you, so remember it well… ❤"
With that, Elysia sis pressed her lips to my neck.
She rubbed them slowly against the spot where she'd just planted a quick kiss, then bit down gently.
"Ngh…"
The first sensation was definitely a twinge of pain.
But… when sis sucked on the spot she'd wounded, a massive wave of pleasure crashed over me.
"…!!"
"Hehe… ❤ That's how you leave a mark. Got it?"
"Yeah…"

Elysia sis smiled with her eyes as she pressed her finger against the spot on my neck and said,
"Now that I've marked you, you're all mine ❤"
My heart nearly exploded right then.
Just moments ago, she'd had that slutty look on her face, and now she was saying something so heart-fluttering.
Heat rushed straight to my face.
"…Saying it like that feels kinda weird."
"Why~? It's basically like stamping my seal on you."
Elysia sis giggled mischievously.
Sis knew exactly how to drive a guy crazy.
And yet… she was so damn lovable like that.
If this was a dream, I'd never want to wake up.
"…Then can I leave one on you too?"
"Yeah ❤ I showed you how for a reason, didn't I?"
"In that case…"
The second she gave permission, I lowered my head and buried my face in the nape of Elysia sis's neck.
Her sweet peach scent wafted from that creamy white skin. Just like she'd done to me, I bit down gently—careful not to hurt her.
"Nnh…!! ❤"
A slutty moan escaped as I nipped her neck.
Then I stuck out my tongue and lapped at the mark.
"Hoot, ah… ❤ Nngh ❤ Hnnngh… ❤"
Elysia sis trembled and let out a string of moans.
"…Looks like it marked nicely?"
"Yeah. Feels like it came out perfect. I should walk around with my neck all exposed so everyone knows I'm Kyle's."
"N-No, you can't do that."
"Nnh, why not?"
Why not? Even if she was acting all lewd right now, Elysia sis was still the Saintess of Purity.
Parading around with a hickey on her neck? If the Church or the Academy found out, the whole school would flip.
"…You're a saintess, sis. If anyone saw you like that…"
"But they need to know you're my man so no other guys hit on me."
"I get that, but…"
Who wouldn't want to brag that Elysia sis was his girl?
All the dudes constantly buzzing around her were a pain in the ass already. If I could, I'd tell her to flaunt it.
"…Still, hold off for now. You've got your position to think about."
"Nnh… Fine, I get it. But in return…"
Elysia sis pulled me into a tight hug.
"…You'll let me mark you whenever I want, right? ❤"
"If it's just us… sure…"
"Pffft. Promise?"
Mwah.
She planted a kiss on my cheek and flashed a bright smile.
In the end, that perfect mix of slutty and sweet got me so worked up… my cock swelled even harder inside her.
"Oh my. Getting even bigger in there, nnh… ❤?"
"…It's 'cause you're too gorgeous, sis. Way too much."
"Hehe."
She stared right at me, then suddenly clenched her pussy walls even tighter.
Squeeze—
"Guh…!"
"So cum inside me then. Until you're satisfied, Kyle."
So slutty.
Utterly depraved.
A saintess sis begging me to fill her up while massaging my cock so tenderly with her pussy? I couldn't hold back anymore. I mounted her fully and—recalling some porn book I'd read—lifted my hips and slammed down.
"Nngohhh!! ❤"
The second I thrust in deep, Elysia sis let out a vulgar wail.
"Haaah, Kyle's cock is the absolute best… ❤"
"You like it that much?"
"Nnh… ❤ It just pounds my baby chamber so good, I love it ❤"
"…You're such a slut."
Elysia sis's face was already melted in ecstasy, but that only made her cuter.
"…That's why I'm gonna keep cumming until I'm satisfied."
"Ufufu, yes ❤ Flood my womb with your thick baby batter, Kyle ❤"
This slutty saintess sis.
Her words kept chipping away at my sanity until I heard the last thread snap in my head. And with it—
Splatshhh!!
"Eekiiih?! ❤"
I rammed my cock deep into her core.
"…Keep your head on straight. I'm holding back from blowing my load right now, so just take it."
"Nnh ❤ I'll keep it together like you said, Kyle."
I gripped her waist tight and started pounding away.
Slap slap slap slap slap—!!
"Ngit, nngh!! ❤ Ahhhn ❤ Hoot, oooh! Ohngh ❤"
The wet smack of flesh on flesh, nonstop. Elysia sis's vulgar moans.
The room echoed with the filthy symphony.
"Hff, haaah…"
"Ahng ❤ Ah, Kyle ❤ So, good ❤ Love it ❤"
That alone was plenty stimulating… but her clinging to me, moaning how good it felt? Overkill.
Her pussy wouldn't let go, squeezing relentlessly, and I could feel the cum rising from my balls.
"You're a real lewd saintess… sis…"
"Eh, heheek… ❤ That's why you love it, right! ❤ Don't you…?"
Elysia sis panted, forcing a smile through the gasps.
"It's a side no one else gets to see… ❤"
She was right.
Thinking back on our five years together, sis never showed this private side to any other guy but me.
She was only like this…
Because it was me.
That made it even better.
It felt like she really, truly loved me.
"Yeah. I'm so happy."
"Heehee… ❤ So from now on, ahn! ❤ You only show this side to me, okay Kyle? ❤"
As if I'd show it to anyone else. The girl I loved was right here, looking this adorable.
"…Obviously. Only for you, sis."
I hugged her tight, and she lifted her head for a kiss, then locked her legs around my waist.
Like she never wanted me to pull away.
Her pussy walls clung to my cock without a millimeter of space.
"Kgh, sis…! If you squeeze like that all sudden…"
"I want your cum, Kyle… ❤"
Elysia sis whispered.
"Cum inside me ❤"
How many guys could hold back with their dick buried deep and words like that? Not me, that's for sure. The urge to cum overwhelmed me, and I unloaded straight into her depths.
Spurt spurt spuuurt!! Splurt, spluuuurt!!

"Nnhik, heeeek… ❤ Oohng ❤ Ooohng…!! ❤"
As I flooded her womb with my cum, Elysia sis arched her back and squirted all over my lower belly.
Was this what they called a woman's climax in those books? Utterly depraved.
"Heeek, heeee… ❤ I can feel Kyle's cock juice filling me up… ❤"
Elysia sis plastered herself to me, twitching nonstop.
"Gonna… take it all… ❤"
"Hff…!"
Her pussy clenched hard, like it wanted every last drop. Only after I'd squeezed out even the remnants stuck in my urethra did it finally relax.
"Hehe… ❤ Now my insides are stuffed full of Kyle's baby batter ❤"
"…Where do you even learn to say stuff like that?"
"From reading all those naughty books."
"What kinda books are you even reading…"
Elysia sis giggled and booped my nose with her finger.
"So, you hate it? Your slutty saintess sis."
"…I never said I hated it."
"Ohhh… ❤"
She shifted her hips a little, pressing our crotches flush together, and whispered,
"Wanna go all night? ❤"
…Damn, she really knew how to make a guy lose it.
"…I'm ready if you are."
"Pffft. Good. So, wanna dump another load of your thick cock juice into sis's baby chamber?"
"If that's what you want. But… you started this, so you take responsibility."
"Of course ❤"
Honestly, what guy could just let that slide? In the end, I forgot all about becoming a Holy Knight soon and ravaged her warm pussy all night long.

"Kyle, I love youuu ❤ Nnght, love yooouuung ❤"
…Looks like sleep was off the table for a while.
