I was home alone, sitting in my room reading a magazine. My blonde hair
was in a ponytail, as I usually kept it. I sighed, completely bored out
of my mind. My lab-Shepard cross sat at my feet, snoozing. His name was
Shep, and he had been a birthday present to me when I was 13. Now I was
I guess I ought to tell you my name. I am Tina Simmons, and that is all
really. I'm a cheerleader at school, and I guess you'd say I was
popular. I wasn't a slut, but I had sex before. Quite a few times
actually. Anyways, let me finish telling you what I was saying...
I wasn't wearing anything, since the air conditioner was out and it was
a hot day. Who cared anyways? I was home alone.
I threw my magazine onto the floor, and got off my chair, standing on my
hands and knees, ass in the air, looking under my bed for another
Suddenly I felt a warm sensation on my ass hole, a good sensation. I
turned my head, and saw Shep standing there, lapping away at my ass.
"Shep!" I said, but I didn't stop him. It felt good actually. His
tongue moved down a little ways, licking my shaven pussy, and I moaned.
I backed up a little ways form the bed, and Shep moved with me,
continuing to lick around my pussy and ass. It felt really good, just as
good as if it were a real guy doing it. Better even.
Sheps tounge probed into my ass, and I let out another moan. How nice it
was! But suddenly the licking stopped. I looked back, and Shep was
staring at me with an odd expression on his face. That's when I saw his
cock was coming out from its shaft. It was huge, maybe 8" already, and
it was still coming out.
Suddenly Shep leaped towards me, and mounted me, claws scrabbling
against my back, and then he held on tight. He was thrusting his cock at
my ass, I could feel it hitting just around my ass hole, be he hadn't
managed to get it in yet.
"Shep!" I scolded, and lifted my arm so I could push him off. But I
nearly fell over when I did that. And then suddenly I felt his cock slam
into my ass, and I cried out partly in pain and in pleasure.
Holy shit, was he thrusting like mad! I was screaming in pain, as his
cock was wearing my ass raw. But after a minute it began to feel good,
and my screams became loud moans of pleasure.
And suddenly he was cumming, buckets of it into my ass. I started moaning
even wilder as I felt it drip out of me. I orgasmed, and it felt
wonderful. I thought maybe Shep would be done then, but then suddenly,
pain shot through me. It felt his a golf ball was being shoved up my ass.
I later learned that it was his knot.
I cried out in pain once more. His cock was so deep into me now, and he
was still cumming like crazy. I felt some leak out from my ass, and drip
down onto my wet pussy. I started moaning again, and Shep was still
thrusting fast, and harder.
And then he turned, and I gasped as I felt the large knot pull on me.
Fuck, it hurt! He began to walk, and I felt it pulling on my ass.
"No! Shep! Stay!" I yelled, but Shep completely ignored me. I fell, and
he dragged me away from the bed, towards the door of my room. Tears were
running down my cheeks from the pain. But it still felt so good, so
Finally, I felt as the knot moved forward, and out of my ass, followed by
the rest of his cock, and a lot more cum. SHep walked away from me then,
and curled down on the rug nearby.
I lay there for a few minutes as cum continued to leak out of my ass. I
had never been fucked up the ass before until now. And by a dog too! But
shit, it had felt so good. And I wanted more...
Weakly, I got on my hands and knees, and backed up towards Shep. He
opened an eye, and then jumped up onto me again. This time I was ready
for it. I felt his cock hit around my ass again, but lower this time. And
then it slid into me, but not into my ass, but into my pussy this time!
I cried out loudly in pleasure as his massive cock slid in and out of me.
He had claimed me as his bitch-slut now I guess. I didn't care though.
It felt so good to be fucked by him, and it was the best fucking I had
Shep came again, the cum shooting deep into my hot, wet pussy. I
didn't want his knot to get into my pussy though. "Down Shep!" I said,
but he ignored me, and continued humping.
I felt the huge knot pounding closer and closer to my pussy as he
thrust in deeper. "No!" I cried, but it was too late. His knot slid
in with ease, and it slowly made its way deeper into my pussy as he
Ten minutes later, his knot was still in my pussy, but Shep wasn't
thrusting anymore. He turned again, and I felt the knot shift around
inside me. The floor was soaked with cum- both his and mine. My pussy was
dripping my cum, and his too. He pulled hard, and I cried out as his cock
pulled out from me. Cum was pouring out from my pussy, and still from my
ass even! I was so sore, but I was feeling really good.
I lay down on the floor, laying in the cum. My hair was getting filled
with it buy I didn't care. She was lapping it all up now, and lapping my
pussy and ass clean of the cum.
Now that I knew Shep liked this, I'd have to do it again... soon.
