Fucking Katie my sister-in-law

I never in a million years thought what happened last weekend
would happen. I traveled with my family to my sister-in-law’s
house to see her new digs. Katie is 26 years old, 5’7″, 125 lbs,
long blond hair, brown eyes with lips that go on for miles. She
looks like a softer Britney Spears.

Anyways, I was unpacking the minivan while she gave my wife and
kids a tour of the house. Her husband came out and gave me a hand
with the bags. We carried everything upstairs, then Jim, her
hubby, went into the room everyone was in and asked my wife and
kids if they wanted to come downstairs and see the family room he
was building in the basement. Everyone trucked down the stairs
and around back to the stairs to the basement except Katie. She
stopped in the bedroom I was in and asked if I needed anything.

I don’t know what came over me, but I smiled at her, walked over
to her, grabbed her by both arms and threw her behind me onto the
bed. I then shut the door and locked it. She was stunned, but
popped up off the bed and said sternly, “What the hell are you
doing?” I grabbed her again, this time kissing her forcefully on
the lips and backing her up against the wall. She was trying to
push me away but I was too strong for her, and she couldn’t yell
because I was pressing my lips so hard against hers and holding
her arms tightly against her sides.

While pressing her against the wall with my lips and chest, I let
go of her left arm and brought my right hand down to her shorts.
I grabbed her roughly between the legs, and she groaned and tried
to close her legs and pull my arm away. She still could not move
too much or scream, although she was putting up a hell of a
fight, because of my lips and chest pressing on her. I slid my
index finger inside of her shorts and found her dry pussy. I
slowly forced my finger into her, which made her gasp and
struggle harder. I jammed it in and out about a half dozen times
and then forced in a second and then a third finger. She was so
tight! After about a minute of vigorous finger-fucking, I could
tell she was getting wet, and her stuggling was getting less and
less vehement.

I went for it, and shoved my tongue into her mouth; gasping
again, Katie tried to struggle, but the combination of my fingers
and tongue must have broken her as she started to reciprocate
naturallly to the tongue lashing and took her hand away from my
hand that was fingering her now-soaking pussy. Since she wasn’t
resisting anymore, I took my left hand off her left arm, and felt
her bring both arms up around the back of my waist to hold me
while I roughly shoved her shorts down with both my hands.

I broke away from her to yank her shorts and underwear down to
her ankles, and she leaned forward and said, “NO! We can’t! We
have to stop!” I popped back up and shoved my tongue into her
mouth again, and after a minute she relaxed and started tonguing
me back. I didn’t know how much time I had left before everyone
came up from the basement, but I had to go for it. I shoved my
shorts and undies down to about my knees, and my now-hard 10
incher sprang forward. I thrust into her with a start; her arms
came up around my neck and she clasped her hands to hold on for a
fucking.

I railed into her again and again, faster and faster. Katie’s
breathing increased, and she started moaning. She must have been
farther along than I thought, because in short order her twat was
tightening on my cock and she was writhing in orgasm. Her knees
began buckling, and I pulled out of her and roughly spun her
around to face the wall. I spread her legs with mine, then
re-entered her wet vagina from behind. After some violent
thrusting, we both started to hear voices; they were coming up
from the basement!

I had no idea if this situation would present itself again, so I
quickly pulled my cock out of her pussy with a pop and shoved it
into her asshole! She cried out “NO!” rather loudly, and we heard
Jim call out, “Katie? Did you say something?” She was a virgin
back there, and I could tell it hurt but I didn’t care. I leaned
back, grabbed a fistful of that long blond hair, and pumped my
cock farther into her asshole. When it was all the way in, I
pumped her ass about a dozen times, quickly, then blew my load
inside of her.

We could hear everyone coming up the stairs! I pulled out of her
and yanked up my shorts. Katie frantically grabbed her shorts and
ran into the adjoining bathroom and shut the door. I turned
quickly and threw open some suitcases, then went over the to
door, opened it, and went back to unpacking. About 30 seconds
later, everyone made their way into the room to get me,
oblivious. “Where’s Kate?” my wife said. “In the bathroom,” I
replied. We all turned and headed downstairs into the kitchen.
