Summary
     A girl takes her brother home after receiving a call from her mother
     that her flight was canceled in a storm, then she take a quick nap
     and wakes up to her brother watching porn on his phone, then things
     get out of her control as she gets caught by him as she masturbates.
I heard my phone ring as I walked home from school, making me pull it out and
smile as I saw it was my mom.
“Hi mom.” I said. “Are you home yet?”
“I'm sorry honey.” My mom said with a sigh. “There is a blizzard here and it
canceled my flight.”
I sighed in frustration.
“I hear you honey.” My mom said. “I miss you too. Please continue being a good
girl and look after your brother.”
I looked around for him and saw him lagging behind.
“Thanks for reminding me.” I said. “Get off your game and pay attention to
where your walking.”
My mom giggled.
“I'll call you when I'm on my flight.” My mom said.
“Okay, I'll be waiting.” I said and hung up, then looked at my brother as he
was still playing his game.
I growled and grabbed his arm, then started to pull him home.
“Why are you in charge?” My brother asked. “I'm older so I should be in
charge.”
“You don't have what it takes to take charge.” I said with a giggle, making him
roll his eyes and went back to his game.
I hugged him.
“You know I'm joking right?” I asked.
“Yes.” My brother said.
“So what do you have planned when we get home?” I asked. “Mom is in a blizzard
and won't be home for awhile.”
My brother looked at the snow on the ground, then smiled.
“How about you eat snow?” My brother said as he scooped some up.
I grabbed it from him and ate it as he stared at me in confusion.
“Now that's done, what next?” I asked with a grin.
My brother smiled as he rolled his eyes, then he grinned.
“How about you give me your candy.” My brother said.
I stared at him, then reached into my pocket as his face filled with shock as I
pulled out my Lifesavers and gave it to him.
“Next?” I asked with a giggle.
“Are you okay?” My brother asked as his face filled with worry. “You never
share your candy, well the last of it at least.”
“I'm fine, I'm just wanting to make you happy today.” I said.
“Um, okay?” My brother said in confusion. “I thought you knew I'm always happy
with you.”
“You sure fooled me.” I said. “You look to be board right now. Boredom isn't
fun and not having fun wouldn't make me happy.”
My brother smiled and shook his head as he went back to his game, making me
smile as I looked forward. Once we got home, I saw my German Shepherd come
charging to us.
“Incoming.” I said. “Brace yourself brother.”
“Crap.” My brother whined as he put his game away, then I saw my dog look at me
at the last second just before she tackle me to the ground with kisses, making
him laugh. “Wow, what a perfect fake-out.”
I whined as I couldn't get her off me.
“Come on Lilly, get off her and give her some air.” My brother said with a
giggle, then pulled her off me.
Once I got to my feet I grabbed snow and threw it at Lilly in frustration,
making her snatch it out of the air and eat it. I sighed and walked to the
door, then pull out my key and unlocked the door. Once I was inside, I walked
to my room and flopped on a bed.
“Get off my bed.” My brother said.
“I don't want to.” I moaned. “I'm comfortable now.”
“Fine I wonder how my new cushion feels like.” My brother said as he sat on me.
“Your to light to crush me so that won't work.” I said with a giggle.
“Fine by me.” My brother said as he laid down on me. “My cushion is nice and
fluffy today.”
I giggled, then fell asleep.
“Did you seriously fall asleep with me on you?” My brother yelped.
“Um hmm.” I moaned as I nodded with a smile. “How long did it take you to find
out. I feel a lot better now.”
“Unbelievable.” My brother said and got off me.
I giggled as I sat up. I looked at the clock and saw it was now six.
“So it took you two ours to realize I was asleep?” I asked, then grabbed his
phone. “What game makes you do that?”
I stared in shock as he was watching porn, then I looked at him and saw him
blushing as he was biting his lower lip as he tried to hold back a smile with
nervousness on his face. My eyes look down and I saw his pants were off and he
had a bulge in his underwear.
“Okay.” I said nervously as I felt myself becoming aroused and gave him his
phone, then walked to the bathroom.
I washed my hands as I looked at myself and saw he didn't make a mess on me,
then I took a deep breath and turn around. I saw my brother standing there with
worry on his face.
“You're not going to tell mom are you?” My brother asked.
“Nope.” I said as I saw he didn't put on any pants. “You're not the only one
that masturbates in this house. However on top of your sleeping sibling is a
different story. That is kinda... never mind, I'm not going down that road
while in our current state.”
My brother laughed as I walked passed him.
“Are you hungry?” My brother asked.
“Please don't feed me cum filled food.” I said nervously as I turned to him,
then I saw the cum on his shirt, making my crotch heat up as I look at his
bulge that was now smaller.
My brother laughed again.
“I won't do that to you.” My brother said as he walked to the kitchen.
“Fuck, now I have to masturbate.” I mumbled.
I walked my room and closed the door, then got undressed and got under the
covers in my bed. Lilly looked at me as I saw her nose start to twitch, then
she stood up and started to sniff around on me until she found my crotch. I
smiled as I knew she smelled my arousal now. I pulled off the covers and opened
my legs, making her sniff my crotch. I bit my lip as I felt her start licking
me, making me let out a moan.
“God why didn't I think of this before?” I moaned.
After a few minutes of her licking me, she pulled her head away, making me open
my eyes and let out a scream as I saw my brother standing there staring at me
with a cherry colored face.
“Um.” Was all I could say as I looked around nervously for an excuse, then I
saw his tent in his underwear, making me smile nervously. “Are you wanting to
take over?”
My brothers grinned nervously and shook his head as he fled. I took a deep
breath as I tried to calm myself, then I grabbed Lilly's head.
“Finish what you started.” I growled.
I heard my brother laugh, making me look at the door and saw him peeking at me
from around the corner.
“Don't watch...” I stared to say, then yelped out as Lilly started to lick me
so more. “Fuck it watch me, I don't care. God she is so damn good at this.”
My brother laughed and walked into the room, but I saw he was now naked
completely. I stared at his four inch hard shaft in disbelief, making him
smiled nervously as he started to become a cherry again. I watched him sit down
and pull out some massaging oil form between his mattress. I stared at him
nervously as he started to masturbate in front of me, then I looked at Lilly as
she wasn't licking me anymore and saw she was now laying down and trying to go
back to sleep. I stood up and walked towards the exit, but my brother grabbed
my arm, making me look at him and saw him staring at me in worry.
“Please don't go.” My brother said. “I'm sorry for making you nervous. Is that
offer still on the table?”
I looked at his shaft, then felt my heart starting to race as I nodded. My
brother smiled and pulled me to his bed.
“What do you want me to do?” I asked.
“How far are you willing to take it?” My brother asked, then he held up his
phone and showed me a picture of a man having vaginal intercourse with a woman.
“Are you willing to do that?” My brother asked.
I stared at him nervously, then nodded.
“Do what you want to me.” I said, but my voice came out shaky.
My brother stared at me in worry.
“Are you sure?” My brother asked. “I don't want you fearing me.”
I laid down and spread my legs, making him look at my slit, then I saw pre bead
up on his shaft. My brother looked at the pre as he saw me look at it, then his
face filled with nervousness. I watched him reached under his bed and pull out
a bag, then held up a condom, making me smile.
“Why in the world do you have that?” I asked.
“I use them to catch my cum when I don't feel like making a mess to clean up.”
My brother said. “Are you wanting to have sex still?”
“Do what you wish.” I said. “I'm not brave enough to ask a random boy to be my
boyfriend, but I love you already so I don't fear you.”
My brother smiled and got down to my crotch and started to lick me, making me
close my eyes in pleasure, then I felt him spread my lips as he stopped
licking, making me open my eyes and saw him staring at my slit.
“Well this isn't going to make my horniness go away.” I said.
My brother looked at me, then smiled.
“I'm sorry, I never seen a pussy up close before.” My brother said. “Turn over
and put your ass up please.”
I stared at him for a second, then did as he said. A few seconds of nothing
happening passed, making me look back and saw him putting on the condom. I
smiled as I never expected him to be responsible. Once he got it on, I saw him
look at me, then smiled as he saw me smiling.
“Are you ready?” My brother asked.
“I’m born ready.” I said with a giggle, then put my head down.
A few second later I felt nothing, but before I could look back, I felt
something touch my backdoor, making me gasp.
“Go slow!” I yelped.
“I know.” My brother said with worry in his voice as he slowly pushed in.
I moaned as I felt he really lube himself up, making it feel slimy going in,
then I felt a slight stretch, but no pain.
“That was unexpected.” I said.
“Does that mean I don't have to go snail pace now?” My brother asked.
“Yep.” I said. “Just don't give me burns going to fast.”
My brother giggled, then started to fuck me. A few minutes later, I started to
pant in pleasure as my brother didn’t make a sound. I looked back and saw him
smiling as he stared at me.
“Ready for the other hole?” My brother asked. “This one isn't giving what I
want, but hearing you pant like that is.”
I nodded, then he pulled out and grabbed his shaft.
“No, I don't want an infection.” I said.
“Right sorry.” My brother said and grabbed his condom bag, then I saw his face
fill with worry as he looked at the floor. “Shit, I’m out of condoms.”
I giggled.
“I don't care.” I said.
“Well I do.” My brother said. “I don't want mom angry once she finds out that I
made you pregnant.”
“Then I guess we are done.” I said with a sigh.
I tried to get up, but my brother pushed me down as he sighed, then took off
the condom and looked at me. I sat up and pushed him down, making him stare at
me as I started to suck him. My brother moaned as his face filled with shock.
“I think I got the wrong size condoms.” I said. “That is a major difference. I
couldn’t feel much before.”
I giggled and closed my eyes as he started to fuck my face, then I felt him
touch my face, making me look at him.
“Thank you for being the best sister in the world.” My brother said.
I smiled and nodded, then I crawled over him until his shaft was at my slit. I
looked at my brother’s face and saw fear in it now.
“Just do it.” My brother said as he stopped me from trying to leave. “If you
want it, then I don't care anymore.”
I smiled and pushed him in, making him gasp in shock. I giggled as his face was
priceless, then I laid down on him and start to kiss his neck as he started to
fuck me as he wrapped his arms around me. A few seconds later, I started
panting loudly as I felt myself approaching my climax, making me push down on
him as I clamped down and moaned loudly. My brother gasped as he let out a moan
as his face filled with worry, then I felt him shoot deep in me.
“Definitely not allowing you to use condoms anymore with that feeling shooting
in me.” I said.
My brother let out a nervous laugh.
