My Sister Beth

I was in my late teens and I just came back from the
last day of the term at school. As it was the last day
of school we were allowed to go home early. The
only person I expected to be home was my sister
Bethany, her school finished earlier than mine. I
opened the front door and could hear loud music
blasting from my sisters room. It was unusual for
her to play music this loud so I went up the stairs to
investigate. As I got further up I could hear this the
sound of someone jumping on her bed. " she must
be dancing and jumping to the music on her bed," I
thought to myself. I planed on embarrassing
Bethany by taking a video of her and showing it to all
her friends. I reached her room door and pulled out
my phone to take a video of her. I started taking the
video and then opened her door with the phone
aimed at her bed. What I saw next shocked me. My
sister was lying on her bed with some guy on top of
her thrusting his dick mercilessly into her vagina.
Bethany was moaning and coaxing him on by biting
her bottom lip. You could tell they were both about
to cum if I hadn't shouted, " what the hell!" The
moment I shouted Bethany and the dude both pulled
up the sheets to cover their naked bodies. I shut the
door and ran into my room. I couldn't believe what I
had just seen. I checked the video to make sure I
had seen correctly and sure enough there was a
clear video of my sister having sex. I played the
video three times to make sure. Then my room
door opened and Bethany came in ...dressed it crumpled clothes and with her hair messy.
She was breathing heavily and her face was red
partially from embarrassment and partially from
almost cuming. Now before I go any further let me
describe Bethany to you. She's my sister and has
long shiny brown hair. She's kind of rebellious and
knows how to look after herself. She likes to do
what she wants even if that means 'doing' what she
wants as I learned today. She has sexy green eyes
and can look sexy without even trying. No matter
what she wears or does guys always want her and
will do anything for her. She is two years younger
than me but her pretty face looks even younger. Her
body is another story, it's fully developed with
curves in all the right places, a light tan and massive
full grown breasts. Her bum is nicely rounded and
I've noticed other guys staring. Ok back to the story.
" I'm sorry you had to see that, I know I'm too young
to be doing it but please don't tell anyone," Bethany
pleaded, " just delete the video and we can forget
this ever happened." I sighed. " did you and that guy
get each other off? " " no, we almost did " " ok I
can't talk to you like this. Go back to your room and
get each other off then you tidy up and tell that guy
to get out. When you've freshened up come back
here." When Bethany left the room I watched the
video one more time. Maybe the guy was raping her
or maybe he had pressured her. But as I watched the
video all my thoughts were proven wrong. Bethany
was the one in control here, she had asked him to do it with her. The guy
was just going along with it in the same manner any
teen boy filled with lust would. I had to admit after
watching the seven seconds of sex followed by the
panic of them when I shouted on video did turn me
on. My sis looked so hot in the video. If I was in the
place of that guy I would probably sleep with her
too. I was no better than that guy, who am I to ruin
his chances of having mind blowing sex with my
sister. When my sister returned, released from
tension she was looking calmer. She had changed
her clothes and combed her hair. " so, ummm are
you going to tell mum and dad? " she asked in a
nervous voice. Her light green eyes made her look
even more like she was at my mercy. I thought this
through and replied, " well that's up to your answer
to my request." "I'll do what ever you want just
please delete the video." My sister had always been
really bossy and in control but now she seemed so
week and powerless. " ok" I said, " if you agree I
won't show the video and I'll even let you keep
having sex with that guy. I understand, we all have
urges that need to be satisfied. So my request is
this, I won't show the video if you agree to do what
ever I tell you when I tell you. Deal?" I could tell
Bethany didn't like this because she hated doing
what she was told but she had no choice. After a few
seconds of giving me angry looks she said, "ok."
"Good," I replied " can you delete the video now?"
She asked " no," I replied, "it's the only way I know you'll obey me" " ok what do
you want me to do?" " well ummm, how do I say this,
I need you to help me with a 'hard' problem of
mine." I said as I pointed to the tent that had formed
in my pants. " you want me to have sex with you!!!"
She yelled in a angry voice. " maybe later if I feel like
it but for now a hand job will do the trick," I replied
cheerfully, " I want you to start slow and pick up the
pace." She scowled at me as she came and sat next
to me. She unzipped my pants and my erection
sprung free. I gasped as her soft hand griped my
penis at the base. Slowly she began moving her
hand up to the tip and back down again. " oh oh,
Bethany......." I moaned softly. I noticed Bethany was
staring at my dick as she slowly picked up the pace.
Every time she reached the top she would create a
tight ring out of her thumb and index finger and that
would make it hard for the head of my penis to go
through. I was loving the feeling so I lay back on my
bed and enjoyed Bethany's work. After a minute
Bethany's speed had picked up a lot. Her hand was a
bluer. I could feel that I would soon cum. "Cum for
me baby, give it to your sis." Bethany's words of
encouragement helped me reach my end. " ohhh,
ohhhhhhhh, ahh, ahhhhh, oh Beth, ohh Beth I'm
gunna, I'm gunna ......... Ahhhhhhhhhh." And with that
I came my biggest load ever. I lifted my hips slightly
off the bed as I came, not minding where the cum
landed. As Bethany squeezed the last drop of cum
out from my dick.
I noticed her smiling. Wow my sister actually likes
giving me hand jobs. When. I sat up and looked at
her she quickly stopped smiling and pretended to
still be angry. I looked her in the eye and she started
to smile. " you like giving me hand jobs don't you?" "
no I hate it" " I know you like it " " ok I guess I like
giving you pleasure, is that wrong?" " no, it isn't," I
said. I kissed Bethany softly and then she kissed
back more intensely. We made out for a while. Then
realising mum and dad would be home soon I broke
the kiss and told Bethany to clean up all the cum.
When mum and dad got home we were down stairs
watching tv like nothing ever happened. that night I
got a message on my phone, " today when we
kissed did that mean anything or was it just the
hormones?" I replied, " Bethany your sexy and
amazing, I love you :) " She replied, " love you too,
can't wait to make you cum tomorrow. P.S it's the
school holidays tomorrow so no parents. Good
night" " good night" The next morning me and my
sister went downstairs when we heard the car leave.
Within seconds we were on the couch with our
hands down each other's pants. With our clothes still
on we made out furiously. With one hand fingering
her I used the other to squeeze her huge breast. She
had one hand stroking my penis and the other to
pull my head closer as we kissed. We were both
close to Cumming but before we did we heard a
door open.
