Yesterday's experience has given me the inspiration needed to write a good chapter to one of my webnovels. The overall reception is good as always, if not more than usual.
Because this scenario is something I've experienced first-hand, and the physical memory of it still burns in my head, I accomplished describing the most I can about Neko-Girl. Her clothes, legs, breast, face, voice, and kuudere characteristics.
I'm so glad I write under a penname. Most authors would feel embarrassed by adding this amount of first-person detailing in their stories. Not to mention, their real names are attached to it.
The reasoning behind my success is because I'm one of the few who allows their voices to become unfiltered from the reactions of society. And the best part, nobody knows who I am.
I turn off the monitor to my computer and art tablet, which displayed my unfinished illustration of the meganekko from yesterday. The reference images I took allowed me to make her transition nicely in the world of 2D. To be honest with myself, I could've had this illustration finished yesterday. But, what can I say? It's hard drawing while masterbating.
Also, I did some late spring-cleaning around my apartment for a visitor.
My step-sister.
I put on my all-black mask before stepping out my apartment.
"Who knew I'd be stepping out here two days in a row," I say to myself while making my way to the train station.
Yesterday after the event, I received a text from my mother telling me my step-sister would be staying at my place for the first few weeks of her summer vacation.
I hate when mother does this. She always tells me things at the last second and expects me to make things work.
Usually, I would ignore whatever mother texts me, trying so hard to isolate myself from my old life. But one person I don't mind coming into my private life every now and then is my step-sister.
"Onii-channn!!!"
I see a tan-skinned, fourteen-year-old girl run off a commuter train while rolling a traveling suitcase. She wears short shorts, allowing her thighs to bounce and rub against one another as she runs. She also wears a sleeveless croptop, allowing her developing b-cup breast to nearly bounce out of her flimsy bra.
She hug attacks me and leans all her bodyweight on me.
This is my step-sister Kamiko, aka the only girl outside of Neko-Girl I've had any physical intimacy with. Speaking of which, it's been about two years since I've last seen her. From the feeling of her chest, her body has developed heavily from the twelve-year-old I used to know. I firmly place my hands on her hips and softly travel up and down her sides while I purposely press my chest onto her breast.
Hmm...
Her breast is developing to become Neko-Girl's size, but unlike her, Kamiko's stomach still has the slight chub associated with most pre-teen bodies. Don't get me wrong, she's still skinny, but that slight chub never fails to turn me on.
"You've grown a lot, Kamiko." The context of what I said is obviously inappropiate in our step-sibling relationship. I'm not under the influence of any alcohol, but the thing is, the two of us has always been open to poking fun of these imouto-type scenarios. Thankfully, Kamiko is also an otaku. Not a shut-in perverted otaku like myself, but still an otaku nonetheless. She has always been open-minded enough to respond well to suggestive comments like this.
"I will continue to grow into the body of your satisfaction, Onii-chan," she says letting go of her grip and standing cutely behind her suitcase, placing her hands behind her back and smilng up at me.
"Your body is already at my satisfaction." I further examine her outfit and maturing body. "I hope you didn't run into trouble on the train."
"I didn't. But if I did, I'm sure my Onii-chan would step in and save the day!"
Her excessive use of "Onii-chans" can tell anyone she has a brother-complex. It's been that way since we first met and I kind of took advanatge of her for it. Any normal person would push away their step-sibling from the constant physical embraces and whatnot, but not me. I plan to get all that I can out of feeling the sensation of a developing woman's body.
"Ngh..." she sofly moans to the side.
I look down at her cameltoe. Legs slightly spread open, she rubs her mound on the handle grip of her suitcase. Her thighs squirm and twitch as she does so.
She probably has to use the restroom. Kamiko always had a tiny bladder, after all. Not to mention, her love of tea, and any drinks in general, does not help her case. Her constant squirming of the legs has always turned me on. Her, along with another girl who should be left unnamed, are the factors leading me to secretly develop a pee fetish. I've never seen Kamiko pee on herself or anything, but it's a sight I'm open to seeing other than in my wet dreams.
"Are you cold?" I play stupid by asking.
"Um... yeah..." Kamiko's face turns red and her arms wrap around her stomach. "Can big brother hold me while we walk to his apartment?"
"Big brother can."
I use one hand to hold onto her love handle, she complys by letting her arms fall to the sides, and the other to grab the suitcase handle. I intentionally aim for her crotch, but only my wrist was able to graze it just slightly.
A responsible and healthy-functioning older brother would give their jacket to their "cold" sister. If I were to do that, though, I would not enjoy the bird's eye view of Kamiko's cleavage on the way home. My boner would also be very visible to the naked eye. Not to mention, a healthy-functioning older brother who knew their sister had to go to the bathroom would take the short cut to their apartment. If I were to do that, however, I wouldn't see Kamiko squirm all throughout the long route.
"Ngh..." she softly moans again.
My focus on her cleavage transitions to her crotch, now covered by her hand.
No way!
Is she actually holding herself!?
I've only seen Kamiko tightly squeeze her thighs together, cross her legs, place her hand on her stomach, bend over, and even press the heel of her foot on her crotch to alievate the pain in her bladder. But never have I seen her use her hand to grab ahold of herself.
My glasses quickly fog up.
From what I could see through my clouded vision, her fingers also appear to be twitching as she's holding herself.
"What fun stuff is around here, Onii-chan," she asks, presumably trying to distract her bladder pain.
"Well, I don't go outside too much. But I do know there's a lot of stuff going on downtown."
"Downtown sounds boring. Since your living in Tokyo, now, have you ever visited Akihabara?"
"Um, I forgot Akihabara was even near..." That was a lie. I obviously know where Akihabara is. The many events, markets, and foot traffic has raised my social anxiety enough so to never visit out of the two years I've lived here.
"Since I'm going to be living with you for two weeks, we have enough time to visit!"
"Yeah, yeah. Sure..." Kamiko knows about my social anxiety. That's why she hasn't asked about my mask, but she is still a kid afterall. There's nothing stopping her yet from wanting to have a life and visit new places. It's only the matter of whether or not I'm mentally able to carry out her wishes. "In the meantime, I have a lot of games we can play."
Her eyes light up. "Really! I love to see big brother's video game collection!" The level of excitement must've been too much for her. Kamiko's jiggling thighs involuntarily close in together, nearly making her trip. Her free hand now grabs onto the lower part of her ass. Her fingers continue to twitch. "How long until we get to your place?"
"Not far. My apartment building is straight in front of us," I say motioning my hand to the building in front of us.
"What a relief..." She sighs. "I wasn't really cold. I just have to use the bathroom."
"You should've been honest."
"I know, but... I have to go really badly..." she pouts her cheeks.
"As bad as the time you slept over in my room overnight, or when we was at the movies?"
"As bad as those times..."
I think my boner grew twenty inches from that statement.
"I see you still haven't learn to not drink everything at once."
"All the drinks they had back at the town's vending machine looked so good! Mom gave me some extra change, so I was able to buy more than one drink!"
I see mother is still spoiling her, that's for sure...
As we make it onto the elevator, Kamiko is now at a point to where she's bouncing in place. Or, at the very least standing on her toes and back on her heel in a repeated fashion. Her breast jiggle from the action.
What a perfect sight...
I sneak out my phone and record my step-sister's desperation in the short amount of time the elevator takes to reach the seventh floor.
"My apartment is on the far end. You see it?" I ask her. Kamiko jumps out the elevator, still clenching onto her crotch and ass, and jogs down to my apartment. It's a good thing she can't jog fast in this moment, I had a spendid time recording her jiggling ass and wedged pantyline. Her short shorts doesn't completely fit around her, so a part of her ass hangs out for my pleasure.
I put my phone back in my pocket and unlock the door for her. She immediately rushes in and leaves her flip flops in the shoe den.
"Where's your bathroom, big brother??"
"It's behind the door to your right," I say closing and locking the door behind me.
"Okay!" She woddles towards the bathroom. "Gotta pee... Gotta pee... Gotta pee..." she sings under her breath before making it inside.
Once the door locks, I immediately sit in front of the bathroom door and whip out my erection. I stimulate it further until I go all out at the sound of urinating.
I've done this shameful act, time and time again in fact, since Kamiko and I started living together. The sound of a girl's relief, like many things, turns me on anytime of the day. To have that experience up close and personal is another story.
I wait for what felt like a minute until I realized there was no sound of urination, but... struggling?
Now that I think about it, there was that one time...
Back when Kamiko was twelve, she desperately had to go so badly she did the potty dance in front of the toilet for five minutes. She had to call me in so I could open the toilet seat and turn her around. If she did any of those things herself, there definitely would've been a mess.
I open my mouth to ask if she's okay, or if she needs help, but I stop myself. Who knows? I might be fortunate enough to fap to the sound of Kamiko urinating on the floor rather than in the toilet.
I begin masterbating anyways, picturing Kamiko performing the potty dance in front of my toilet.
"Nngh~" I hear screeching from inside her mouth.
Has she reached her limit!?
Is she peeing on her self!?
What followed was a shudder escaping her mouth. Then, I hear the toilet seat immediately flip open, her shorts and pantues falling pass her legs, and her ass plopping onto the seat. The rushing sound of urine follows.
"Haaa~" she lets out.
I wasn't fortunate enough to have Kamiko pee on my floor, but making up for lost time on this despicable act is good enough.
Kamiko's urine rushes inside the bowl for a solid minute and a half, allowing me to fully enjoy my session and wrap up early.
Weak, sweaty, and physically tired, I tuck my penis back in my pants and drag myself onto my futon.
