tickling birds

cleaning the cute bellybutton.

My name is Carol, and I have a Little sister, a cute, smart, caring, and petite Little sister, she looks a lot more younger than her real age (even though she’s one year younger than me…), we are really close to each other even if she’s a “Popular” girl and me, her Older Brother, just an ordinary middle school Senior. But, our relationship became tighter after “THAT”.
It was a really, REALLY, hot morning. I went to the bathroom to do whatever I was supposed to do, when I finished I got down to the living room to kill some time. My little sister Eri was there, lying in the sofa, watching some weird stuff that she and her friends like to see, she didn’t notice I was there, so It was the perfect timing to play a joke on her.
Carefully, I got closer to the back part of the sofa, and luckily, she stretched her body, leaving that neat, soft and stretched innie navel of hers right in front of my sight. “THIS IS IT!” I thought on my mind, and quickly got my index finger inside her navel. She let out a moan (it was more like a hic* sound to me, but more cute) and then I got out my finger. Then she was shocked of whatever my finger catched inside her navel. 
MY FINGER WAS PITCH BLACK, and then I looked up to her. “U-um… Carol? A-a-are you mad?” she said with her face all red “Yes, And now I want my revenge” I said to play around with my cute little sister, and then she started to cry…!!!
“I’M SORRY, Sorry, so sorry…!” She said with a lot of tears running from her eyes to her chin. 
“I-it’s okay, don’t worry I was joking, just fooling around with you” I said carefully, not trying to make her cry again.
“R-really?” Eri said with an extremely adorable puppy face.
“Of course!”  I said all excited seeing her cuteness, and then a really GOOD Idea came to my mind. “But I don’t think this is something healthy for a second middle school girl like you!” I said giving me some Mature Airs.
“I know but… it’s difficult for me to clean it… you know, I’m… I-I’m… a little bit sensitive in there, he he…” She said that nervously covering her navel with both of her hands.
“Hmmm… what if I clean it for you?” I said with my heart pumping like a beast.
Somehow, her face lit up a little bit and she accepted my proposition, but somehow it felt like she wanted this… 
I got to the bathroom first to settle up everything I’m gonna need to clean Eri’s navel. Then, Eri came to the bathroom wearing an small shirt, her belly was almost completely exposed. She was blushing a lot... 
“OK. Lie down on the carpet” I said giving the fluffy carpet a pat
Without a doubt, she laid down on the carpet, stretching her petite Belly and belly button and putting her arms behind her head.
“U-um… Carol… can you t-tie my hands up?” Eri said to me giving me her hands ready to be tied up.
“But I don’t even have a ro----” I said but she interrupted “HERE!” Eri gave me a red rope.
(Yeah, I think she wanted this more than me…) I thought while tying up her hands to her back.
“Okay now, Eri, are you ready?” I said preparing a Q-tip in one hand and a lotion bottle in the other one.
“Y-Yeah! Begin whenever you fell like it” Eri said putting a brave face and closing her eyes tight 
Then I slowly poured some lotion into her navel, and then inserted the Q-tip inside her navel. “Kya-!” She was about to start shouting, but she made an effort to close her mouth pressing her lips inside her mouth, “she really is so cute” I thought, and started swirling in the Q-tip to clean her navel, it was so deep that half of the Q-tip was inside it! “D-d-do-DO IT GENTLE…!!! Ah~!” she whispered, so she really is that sensitive inside her navel… 
Then I got out a lot of Q-tips, every Q-tip that got out her navel was Incredibly BLACK, and before half an hour, I finished with her navel. She had a really tired expression, her eyes covered in tears and her checks were blushing in a red tone, she was breathless also. 
“D-does it… look cute… brother?” She asked in a really tired voice
“Yup, it looks more prettier than before” I said in a cool way.
“I… I’m… happy that you like it” Eri said with an adorable smile in her face, putting me on the edge of “Love for little sisters”
I carried her in my arms and left her in her bed. “K-kiss… my navel… please…” she seemed like she wanted to say something else apart from that, but she was too tired to say it. 
“Okay, whatever you say, my cute little sister” and then I got my face above her navel and kissed it, she smiled again and went to sleep.
The day after that, she came up to the house with a bunch of pencils of different sizes and boldness.
“I-I wanna Try something new! It’s just because you’re always slacking off in the house, not because I enjoy it!” She said in an angry tone, but a little bit nervous. 
OH God… what can I do with this Little Sister of Mine?
