My Sister's Secret Indulgence ♡
I caught the faint scent of the panties I'd worn earlier as my sister jerked off to them. ♡
Her cock... it had gotten so completely big. Was it... because of me? Ugh... I'm so embarrassed...
And what was this tingling, electric feeling? It scared me to feel any more of it. This was my first time experiencing anything like it.
"Ah, right! I'll teach you how to put on a bra."
She reached around me with a soft rustle, the hooks clicking into place. "You do it... like this."
My sister began explaining the proper way to wear a bra in careful detail. I could feel her eyes flicking over my chest again and again. Even while her lower half was fully erect... she kept stealing glances at my breasts.
"U-um... th-thank you... hehe."
"You need to be able to do it by yourself, so I'll show you a few more times."
She repeated the instructions patiently until I got the hang of it. Having her stare so openly at my chest was incredibly embarrassing... but I couldn't deny how it made me feel.
Click.
"There... I've got it."
Once I could fasten the bra on my own, my sister smiled and gently stroked my hair.
"Hehe... Good job, Zwell."
The moment her hand touched my head, that strange tingling sensation spread through me again. Standing together in this tiny fitting room felt... a little embarrassing. And something else... something I couldn't quite name. Uuu...
"Zwell? Are you okay? Your face is all red."
"N-no! It's just... does this bra size fit right?"
"Yeah. It's perfect. Let's buy a bunch in this size."
And just like that, my sister forced me to buy way too many bras. She only picked out the sluttiest ones... the kind that made my face burn just looking at them. She was being so mean.
"Ready to go?"
She took my hand and led me out. But right as we were leaving the store, she suddenly shouted, "Wait a second!" Then she told me to wait outside while she slipped back in. It looked like she was buying something else in secret. When I tried to peek, she quickly hid it, so I never saw what it was.
She was probably buying underwear for herself. She must have been too embarrassed to show me.
With her secret purchase complete, we started walking through the bustling streets carrying five huge paper bags.
"Sister... th-thank you so much for buying me all these clothes today..."
"Huh? Thank you? If you're that grateful, give me a kiss."
Eh... euuu... There were people everywhere... But more than that... was she really preparing herself to break up with me? That expression on her face... she looked way too happy. Ah... maybe she was trying to give me one last wonderful memory...
"Zwell? Aren't you going to kiss me?"
"U-um... okay..."
I stood on my tiptoes and gave her a quick peck on the lips.
"Hehe... Zwell's lips are so soft."
The way she smiled so brightly... it was the same lovestruck expression she'd had back when I was still a guy. What the hell... My sister couldn't possibly be a lesbian... or maybe she was bisexual? What was going on?
"Zwell, want to get something delicious to eat?"
"Eh? But you already spent so much money today..."
"Pfft... Don't worry about that. Ah, you're just too adorable..."
She looked at me with eyes dripping with honey, saying such heart-fluttering things...
"Th-thank you. You're super pretty too, sister."
At those words, she beamed and grabbed my hand again, pulling me along.
"Ugh... Haa... I'm so full..."
My sister let out a cute little burp as she climbed into the carriage.
"Hehe... I'm full too, sister."
"It was all so good... The pasta and steak were absolutely perfect, though I was a little disappointed the bread came out cold."
"Thank you so much for today, sister."
"Y-yeah..."
Once we were both settled, the carriage started moving with a rhythmic clatter.
"But sister... if you ever want to break up with me... you can tell me anytime. Before you dump me, I wanted to make some good last memories... I know all about it. I would never ask you to love me now that I'm a girl. Even if you can't love me anymore... I'm okay with it. So don't feel burdened and just tell me whenever, alright?!"
I'd been holding it in, but the hot words finally spilled out. Yet the sister beside me stayed completely silent.
"S-sister?"
"Mmm... zzz..."
She had fallen asleep. She hadn't heard a single word.
When she started to slump the other way, I carefully caught her and let her lean against my shoulder.
"Mmm... Zweeel..."
The moment her head rested on my shoulder, she fell into a peaceful sleep. Her soft hair tickled my cheek. The clop of the horse's hooves became a lullaby.
I was getting sleepy too... No, I can't. I have to stay awake while she's sleeping. I have to stay... awake... Uu... euu...
"Zwell! Wake up, we're here!!"
Her voice pulled me from sleep. The sky had already turned dark. We stepped down from the carriage, still carrying all those paper bags.
"Zwell, did you have fun today?"
"Huh...?"
I answered groggily, still half-asleep.
"You... you didn't have fun...?"
Her face crumpled like she was about to cry.
"No, that's not it! I had so much fun."
"Ehehehe... That's a relief."
She grinned at me with that silly, bright smile. It had been a while since I'd seen her look so innocently happy.
"Uuu... It's cold! Let's go inside and eat dinner!"
At her urging, I followed her into the warm house.
"Haaah..."
After putting away all my new clothes in the closet, eating a hearty dinner, and taking a shower, I finally collapsed into bed. My sister climbed in right after me.
"Zwell... I'm tired. So give me a kiss..."
Serwen was always so affectionate.
"O-okay..."
Chu.
"Hehe..."
Was kissing me really that good?
"Zwell, let's sleep now."
She turned off the bedside lamp.
About an hour must have passed. I'd slept too much in the carriage, so I couldn't fall asleep. Just a little longer and I probably would have...
"Ah, fuck... I can't hold it anymore."
Right before I drifted off, I heard her voice. What was she...
She shot up from the bed in an instant, stripped off her bottoms, and revealed her rock-hard cock glistening with precum.
I was about to ask why she'd gotten up, but I was so shocked I quickly pretended to be asleep again.
"Haa... ha... ♡ Zwell... you look so fucking hot... I've been hard enough to explode all day because of you. I thought I was going to lose my mind."
Aaah... what do I do, what do I do, what do I do...
"Fuck... it's all because of you, Zwell. I really can't hold back anymore."
She started rummaging through the laundry basket. Through my barely-open eyes, I could see her pull out a piece of fabric. As she walked back toward the bed, I finally recognized what it was.
????? Th-that... that's...
It was the panties my sister had lent me. The ones I'd worn all day because I didn't have any women's underwear of my own. I'd taken them off before my shower and tossed them in the laundry basket... and now she was pulling them back out...
Uwaaaa...
"Huu... ♡ Huuup ♡"
My sister began sniffing the panties like some kind of pervert.
"It smells so full of Zwell... ♡ Since I lent them to you, it's perfectly legal for me to take them back and smell them... ♡"
What the hell was she even saying?
"Ah... they're wet. Zwell... did you get your pussy juices on them when I was touching your chest?"
I flinched hard.
"Zwell, you little pervert. Pervert pervert. Hehehe... ♡"
While sniffing them, she started stroking her throbbing cock.
"Huuup... ♡ Huuu... ♡"
Her eyes rolled back in ecstasy as she kept inhaling the scent and pumping her fist. Squish♡ Squish♡ Sluuuurp♡ Thick strands of precum oozed from her cock, and the sight made my face burn like it was about to burst.
Because of me... it had gotten that big...
"Haa... ♡ Haa... ♡"
This time, she gently wrapped the panties around her massive shaft. Then she pressed the wet part—the soft fabric that had been against my pussy—right against her leaking slit and started thrusting like an animal in heat.
"Huuuu... ♡ Hng... ♡"
Squelch squelch squelch squelch♡
Then... Spurt—♡Glurk♡
Thick ropes of cum splattered all over the panties, right where my pussy had been pressed against them. Aaaah... aaaaaah... My head felt like it was going to explode. Heat flooded between my thighs. Why... why did seeing this make my lower belly throb and tingle so much... Ngh...
"Huu... Once isn't enough."
She tossed the cum-and-precum-soaked panties into the bathroom, then brought her cock—still reeking of that thick, musky scent—closer and closer to me.
"Ha... haa... ♡ Zwell's hand... it's so pretty..."
She grabbed my hand and... ngh... nngh... wrapped my fingers around her slick, wet cock. Then she folded my hand over the back of hers like I was giving her a handjob and started moving it up and down.
"Huu... Zwell's hand is so soft and cool... it feels so good... ♡"
Pervert. Serwen was a total pervert. I never knew she was this much of a degenerate...
Her wet cock felt completely real against my right hand. So big... so hot... slightly bumpy from the veins... pulsing like it was alive...
"Haa... haaa... ♡ I'm seriously going to lose it."
Schlop♡ Schlop♡ Schluurp♡ Schlop♡
The lewd, filthy sounds filled the room. Glurk... gluuuurk... ♡ More precum gushed out, flowing down the head and shaft, soaking my hand over and over.
"A... auuu... heuuu... ♡"
Schlop schlop schlop schlop♡
Her cock throbbed faster. I could feel it swelling even bigger. She quickly adjusted my hand, wrapping my palm around the head and rubbing it furiously... Spluuurt... ♡
Warm cum shot all over my palm.
"Hek... heeeek ♡ It's still coming out... ♡"
Spluuuurt—♡ Splurt♡♡
Thick, syrupy semen coated my hand. Sticky strands of cum stretched between my fingers like spiderwebs. My right palm was completely drenched in her cum as her masturbation finally came to an end.
