Summary

     at nerd school. He wants to shower, but Tadashi has a better idea of
     getting clean
Notes
     This fic was deleted when my tumblr was. it is based off of
     wowgotomago's photo. Enjoy!
The air was still in my slightly stuffy room. The only noise to be heard was
the irritating ticking of my brother's clock.
Tick, tick, tick...
God I hate that stupid clock...
I lay on my bed reading an X-men comic that Fred lent me. He says "Aw man
Tadashi, you'll LOVE the X-Men series!"... I'm not really a big fan of it right
now. It's hard to focus since my mind kept slipping to the thoughts of my dear
little brother. I want to run my fingers through his messy silk hair and soak
in his delicate beauty. I want to feel his soft trembling body under me as my
hands would slip under his jeans and- STOP! I threw the comic on my pillow and
put a hand on my flushed cheek.
My dear brother, Hiro, and I confessed our forbidden feeling for each other a
few months ago. After that we've been dating in secret. I constantly ask Hiro
if he minds that we have to keep our relationship a secret since I don't think
it's very fair for a boy his age have to experience secret love, but Hiro
doesn't mind. He always tells me that as long as I'm with him, he is happy.
That kid sure knows how to make me smile....
I heard footsteps in our empty house since Aunt Cass is away for the weekend at
some bakers convention. It must be Hiro!
"Tadashi, I'm home!" I heard him announce as he swung our room door open.
"Welcome home Hir..." I trailed off as I saw my little brother standing there
soaking wet, "What happened?"
"Well, I missed the bus TWICE so I had to walk home EIGHT miles. I ran for four
of them because I ended up in the bad part of San Fransokyo," Hiro groaned,
"Now I feel dirty and exhausted." Hiro collapsed on his bed draping one arm
over his eyes.
"Aw baby, I'm sorry that happened, why didn't you call me? I could've picked
you up," I asked. I walked over to Hiro and sat on his bed as I pulled him into
my lap.
"My phone died," Hiro sighed, "I need to shower..."
"How about we shower together? Maybe that will cheer you up," I offered. I
really just want to see my brother naked. He is so beautiful that I could stare
at him for hours.
"Alright," Hiro smiled then leaned close to my ear and whispered, "But you have
to promise that you'll clean me, big brother. I'm a dirty boy." His seductive
words sent pleasurable shivers down my spine. That tease...
Hiro and I made our way to the small bathroom just outside of our room. Hiro
and I are the only two that use it since Aunt Cass has her own bathroom in her
room. I turn on the water and let the room fill with relaxing steam that filled
my pores and let out all of my worries.
"Big brother, why aren't you naked yet?" Hiro asked as he wrapped his arms
around my waist. His chest pressed against my back and his hands played with my
hips just to tease me.
"Oh uh..." My brain couldn't think of any words to say. I just want to pin Hiro
against the wall and taste his sweet skin.
"Here, let me help you," Hiro smirked.
Hiro turned me around so I was facing him. The boy began by slipping his hands
under my shirt and massaging his way up to my collar bone. Then he lifted my
arms and slipped my shirt over my head. I felt Hiro's soft lips kiss their way
down my tones chest until he was on his knees with his mouth over my front.
Hiro looked up at me for approval and I flashed him a needy look since I was
extremely turned on. Hiro used his mouth to undo my jeans! Where did he learn
that?
"Tadashi, can I take your boxers off too?" he asked innocently as his nimble
little hands were teasing my dick by scribbling one finger all over it. He then
began to play with the trail of thin hair leading inside of my boxers as he
slowly pulled the material down.
"Yeah," I breathed.
Once we were both naked, I pulled Hiro to his feet and hungrily pressed my lips
against his. I grabbed his cute ass violently making Hiro gasp.
"Well come on Hiro, you truly are a dirty boy," I whispered in his ear followed
by a small bite to his earlobe. I know Hiro likes it when I'm a bit rough with
him, I'd rather be gentle because I'm afraid of hurting him.
Hiro and I stepped into the shower and let the warm beads of water sizzle on
our heated bodies. Our hands glided over each other as we continued to litter
kisses on each other's lips. I pushed Hiro against the wall and grinded my hips
on his to get friction on my needy cock. Hiro let out some moans and gasps at
my harsh simulation while I just soaked in his pleasurable noises. I then
grabbed our erections and stroked them together causing Hiro to moan even
louder.
"Tadashi, I want to go all the way with you," Hiro managed to say in between
moans.
Hiro and I have pleasured each other, but never have gone all the way. Hiro
continued to say 'stop' whenever I rubbed his small entrance.
"Are you sure?" I asked as I got off of my fragile little brother.
"Y-yeah. You have every part of me except my body, now I want you to have it.
So take me big brother," Hiro held out his arms as if he was offering himself
to me. And I happily accepted his offer.
I flipped Hiro over to he was facing the tiled wall and kissed his smooth back.
I ran my tongue on the sweet tan skin until I reach his perfect little ass. I
spread the globes of flesh appart to reveal the twitching little hole. I
pressed my tongue on it to see how my brother would react and his reaction was
perfect. His body began to tremble with excitement as I continued to lick and
tease the inviting entrance.
"T-Tadashi, stop teasing me," Hiro whined. I chuckled against him causing Hiro
to whine again. I just took those delicious noises as encouragement to continue
my sweet teasing.
I then grabbed the lavender body wash and squirted a bit on my two fingers.
Then I rubbed my little brother's entrance with those fingers until one slipped
in. I have to be careful since Hiro is a virgin and I really don't want to hurt
him. I heard Hiro mewl and whimper in pain at the intrusion.
"Shhh, it's okay. I have you," I said gently as I began to pump the finger in
and out of his tight heat. Hiro's hands clenched the air.
"Hiro, you have to relax," I said.
"Easier said that- Ah- done," Hiro groaned out. I wrapped my other arm around
him so I could grab his leaking cock. Maybe if I play with him, he'll relax.
It worked! I felt Hiro loosen up slightly and his whimpers turned into moans
again. I added another finger inside of him and repeated the same process only
this time I began to scissor him. At the same time, I was looking for that
little bundle of nerves deep within him that will make Hiro scream my name.
"Ah! T-there again!" I heard Hiro gasp. Found it... I removed my fingers though
because I want to save it for when I'm inside of him. Hiro whined as the
absence of my fingers.
"Aw no need to pout baby brother, you're going to get something bigger than my
two fingers," I smirked.
"Mmm can't wait," Hiro moaned.
I lathered my dick with the same lavender scented body wash then brought it to
Hiro's entrance. I rubbed myself against him a bit.
"Hiro, are you sure you want this?" I asked.
"Yes! Just take me, please!" Hiro groaned as he rocked his hips slightly and
pushed his butt out more.
"Okay," I said.
With one swift movement I shoved myself deep in him. I heard Hiro gasp in pain
and his body shook. I grabbed his hot cock yet again and stroked it. I ran my
fingers over the leaky slit which made Hiro clench his body around me. He is so
tight!! It feel amazing.
"Mmm Hiro, you feel amazing inside," I growled in his ear, "Are you okay?"
"Y-yeah, you can move now," he said.
I slowly pulled myself out so only the tip stayed embedded within him, then I
pushed myself back in electing a sharp moan from my lover. I continued this
movement as I tried different angles to find his sweet spot.
"Tadashi, faster please! Take me harder," Hiro moaned.
Those words made me completely lose it and I fulfilled his desire. I heard Hiro
scream out my name as I hit his beautiful little sweet spot deep within him. I
felt animalistic as I continued to pound Hiro into the wall with waves of
pleasure hitting me. I felt myself getting closer to an orgasm.
"I-I'm about to-AH" Hiro yelled as he coated the wall with his sticky seed.
I continued to pound into my little brother's clenching body until I reached my
peak and I planted my seed deep within his overstimulated body. I stayed there
for a second to catch my breath.
When I pulled out, some of my cum dibbled from Hiro's ass and onto his thighs.
I smiled as my little brother's completely drained body.
"Come on Hiro, let's clean you up," I smiled.
After I washed Hiro, dried him off with a fluffy green towel while I grabbed my
blue checkard one. I wrapped mine around my waist and Hiro copied me.
"Nii-san, can you carry me?" he asked.
"Why?" I chuckled.
"I'm exhausted," Hiro smiled as he held his arms out.
"Okay then," I scooped him into my arms, holding him bridal style. I felt my
towel begin to slip off of my hips as I brought Hiro to our room.
I took his towel off and tucked him under the covers to my bed. I spooned his
delicate and tired body to protect him.
"Tadashi," he said, "Thanks for cleaning me. I really was a dirty boy wasn't
I?"
"You were little brother, maybe I could clean you again tomorrow?" I smirked as
I placed a kiss on his cheek, "Go to sleep, I love you Hiro."
"I love you too Tadashi, with all my heart," Hiro mumbled as he drifted off to
sleep. His chest peacefully rose up and down with each breath he took. I
admired his purity and innocence even after I pounded him into the wall.
I can't wait to clean my dirty little brother tomorrow.
