While You Were Away, My Pussy Has Changed (4)

"No, it's not about contraception—it's our actions that are the problem..."

"Could it be my little brother harbors strange feelings for his big sister?"

At her question, I waved both hands frantically, denying it vehemently.

"Absolutely not. How could I ever dare to think that way?"

"Then show me the bold spirit of a real man. I just can't believe your words—I want to test if they're true."

Olivia let out a deep sigh, her tone laced with disappointment.

"I started this guild because you told me to. But lately, you don't seem interested in it at all. You treat me like some guy, ignore my orders, talk back every time... Where did my cute little brother go?"

"Ah, well, that's..."

I scratched my head awkwardly.

"To be honest, sis, I'm scared that if we do it, I'll start seeing you as a woman from then on. My heart isn't as strong as yours. Is it okay if I look at you that way?"

"I've long since tossed aside any concerns for my dignity as your sister. You know that, right? From way back during sword training."

Years ago, right after Pivar passed away, the two of us traveled together. During that time, Olivia threw herself into sword practice like a madwoman. After sessions, I'd often give her recovery massages. Naturally, she ended up naked for many of them. And one day, during practice, she insisted that this particular technique required venting internal heat immediately, so she stripped down. I stood by with a bucket, splashing cold river water on her swinging sword and naked body to cool her off.

"You followed without complaint back then, but now that you're all grown up, you act like men and women should keep their distance."

Olivia grumbled on.

"And you're scared of seeing me as a woman? We were always so close—would getting even closer really be a problem?"

"You're thinking about marriage, aren't you?"

"At my age, it's hard to find a pure-hearted partner, so I gave up long ago. The guild and you are all I need."

"Instead of someone your age, maybe try dating some innocent girl ten years younger..."

"Are you trying to piss me off right here?"

She shot me a sharp glare. I swallowed my words immediately.

"Fine. Today, for the first time, I'll be rude to you, sis. Don't blame me later."

"You're the only one in this world who truly cares for me. How could I blame you?"

I could feel the deep trust and intimacy built from our past solo travels still burning strong in her heart.

"Look at this. It's weird. I swallowed your semen, but no energy's coming."

"Maybe semen loses effect in the air? Turn around and brace against the wall for now."

Olivia stood and walked to the window behind the desk. She placed both hands on it and stuck her hips out slightly.

"Staff might come to report anytime, so you need to cum quick."

"I'm premature—I'll blow in a minute."

"Oh dear. I should brew you some good stamina potion. Who knew you had that issue..."

"Don't take it seriously. Just kidding."

I moved behind her, rolling up her long skirt that reached her ankles all the way to expose her ass. A sexy rear clad in black garter belt stockings and luxurious panties came into view.

Damn, stockings with purple panties. So hot...

Made of expensive fabric, it looked soft and plush even at a glance. Undressing the garters would take time, so I just pulled the panties aside. Thick pussy lips revealed themselves.

Sis's looks like this... Looks delicious...

I licked my lips and swallowed hard. Seeing the pussy of someone I respected and admired up close. It felt more precious than any other woman's, igniting lust that spread through my body. My limp dick hardened.

"Did the water come out?"

To check if her insides were slick, I slid a finger along it. Olivia reacted with a soft moan.

"Hng..."

I rubbed the wetness on my finger to confirm.

She must've gotten turned on while I was jerking off. Nice and wet.

Time to go in. Full throttle.

Since I was fucking sis anyway, I activated every technique I had to show off my skills. I wanted to hear how awesome my little brother was. I craved applause for my amazing dick.

"Here it goes."

As I gripped my rock-hard dick pointing straight up and aimed to insert, I spotted my comrades waiting below the window. They clustered under the tree shade, chatting idly. Sorry, guys. I'll cum quick and join you.

"Hup. Ungh..."

Olivia winced slightly, exhaling hot breath. The tip entered her pussy. Just the intimate touch of flesh sent electric jolts through my mind. Felt too good.

"Hoo, sis... Going in."

Slowly, savoring every inch. Her slick walls welcomed me warmly.

Aah, sis's flesh is so cozy and soft.

I wanted to devote myself to her. No—love her. Her pussy gripped my dick insanely well. I'd obey her every word from now on. Don't stop me.

"Uht... Impressive. Didn't expect you to be packing something this good. Ah... You're filling me up... Move, please. Haa..."

"Sis."

"Yes?"

"Haven't even put half in yet. I'll go all in and move."

Her eyes snapped open from her immersed bliss.

"Only half, and it feels this good?"

"Yeah. Really just half."

"My god. Must've lost my touch since it's been so long. Didn't know dicks could be this size."

"No, it's me. My dick's just big."

"Hng...!"

Thrusting to the hilt, her breathing grew ragged.

"Haa, so hot and hard."

"Not hurting since it's been a while?"

"No pain. But... haa. I underestimated sex. Hng..."

Not only buried deep, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠but with God Touch ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠active, my hands gently caressed her nape. She wouldn't last long. Maybe I'd see the dignified guild master—my cool big sis—break today. Even if she pissed herself in front of me, I'd forgive her.

"C-Contraception Isle working okay?"

"Yes, it's on. Moving now."

I grabbed her hips and started thrusting. Squish, squish.

"Eup... Ut...! Ungh..."

"How's it? My dick usable, right?"

"D-Don't know. Don't ask your sister that. Kgh, ugh, ungh...!"

Olivia's face flushed, her body writhing seductively. Her long-sealed pussy fully opened, a floral scent bloomed from her, her skin gaining startling elasticity and vitality.

She looks prettier than usual.

Guess women need regular sex too. It made her femininity overflow. I'd pound her hard for her sake. Years without a partner—she needed thorough release.

Gonna fuck her powerfully.

Thwack! Thwack! Thwack!

"Wuuungh! L-Little bro! Hot! Ahot, ang!"

Pounding fast, her face looked ready to cry. Her helpless expression under me was adorable. My dick swelled harder.

"Sis, what should I do...?"

"Why? Problem? Ahng, ah...!"

"This is why I said no. I knew it'd be like this. You're getting even better. Too good, driving me crazy."

"Aah...!"

Her pussy clenched, hugging my dick. As I pulled out and thrust, love juices dripped like honey.

Just like I felt love for her in that moment, she surely felt it for me. Sex is mysterious. It turned even my respectful sis into my woman in an instant.

"Sis, your pussy's so sweet I can't escape! Too honey-like! Hek! Hek! I love you!"

"D-Do you really love me?"

"Huh? Of course! I like you! Love you! Driving me insane!"

Splash! Splash! Splash!

"Just heat of the moment. You're such a rascal. Hng...! Ung...!"

She moaned with a smile. Her upper body plastered to the window, her body jolted with each rear thrust.

"Don't say 'love' so casually to other women."

"Sex makes me dizzy with pleasure. Don't know what I'm saying. Haa! Haa!"

I reached around nonstop, grabbed ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her chin, turned her head slightly, and kissed her. She didn't resist. Accepted my tongue naturally, swapping saliva as her pussy swelled, squeezing tight. Juices dripped faster to the floor.

Then, a knock. Knock knock.

"Guild master? Here for a report."

Of all times. No sense of timing.

"Tch!"

I yanked out quick and crawled under the desk. Olivia swiftly sat in her chair, her soaked crotch blatantly visible.

Whoa, sis's panties are drenched.

I quietly savored the sight. Slurp!
