My Girlfriend's Surprise
by Scott (1996)

***

A guy gets the idea to trick his girlfriend into having 
sex with his dog. (F/beast, nc, bd)

***

When I first started dating Eden, I knew she was a hot 
one. She was about 5' 2", barely 100 pounds, with a nice 
set of tits, a small waist, nice hips and the best ass I 
had ever seen. She had the nicest blonde hair ever and 
was the nicest woman I had ever met. 

The first time we went out, I got her in the sack with 
her and she was wild and very loud. I wanted to do it 
every which way with her and I especially loved doing it 
doggy style. 

As we dated more and more she would dress up for me and 
do other things to satisfy my fantasies and quirks. In 
short, she was the perfect girlfriend.

Then one day I asked her if I could tie her up, she said 
yes.

Now, I need to tell you that I have a Rottweiler, Mr. 
Big, and he is huge. I would say he is about 205 pounds 
and very friendly and horny. MR. Big was always coming 
around and trying to hump on people and it would drive 
Eden crazy.

One day while Eden was giving me a blow job, Mr. Big 
started nosing around. I was on the coach and she was on 
her knees bending over me sucking my cock. 

That's when Mr. Big came over and mounted her. She went 
nuts. She screamed, "Your stupid dog is trying to fuck 
me!" 

I replied, "I don't blame him one bit. You've got a 
really hot body." Right them I got this really kinky 
idea and I blasted off in her face! From that moment, I 
had to see MR. Big fuck Eden, but how?

I thought about it for a while and came up with a plan. 
Eden had agreed to let me tie her up. I was going to do 
it and get Mr. Big to fuck her. She agreed to do this 
the week before my birthday as a special treat. We were 
in my house and I took her to the basement. I had asked 
her put on a nice new corset I had gotten her with 
matching garters and hose. I told her to leave the 
panties off! 

The basement gets some light from the ground level 
windows, but they were soaped over so no one could see 
in. I tied her hands together through the rails of a day 
bed that rested against one wall. Now she couldn't move! 
I told her I had another surprise and I put a blindfold 
on her. She actually liked that and said it was making 
her hot. I turned on some music and she told me to close 
the door so Mr. Big couldn't bother us.

I had a setting on my cellular phone so I could make it 
ring. I told her I was expecting a call and I might have 
to take it. We started messing around, I was fingering 
her pussy when timer on my phone rang. I told Eden I 
would be right back, that I had to get a paper from the 
desk upstairs.

When I went through the door at the top of the stairs I 
left it open just a little. When I got out there I acted 
like I was answering the phone. I got on the cell phone 
and acted like I was taking and went into the next room. 

Then I went up to Mr. Big and I started to fondling his 
cock and it started to grow out of its sheath and he 
tried to mount me. 

I'd dome my internet research and found that when a 
dog's cock first gets hard it is very thin and long and 
very sharp. It will easily penetrate a woman. It is best 
to penetrate the woman quickly before it gets too big. 
The knot is also very small at this point. 

I called down to Eden that I had to go outside to get 
something out of my car. Then I brought Mr. Big to 
basement stairs and watched him trot down into the room. 
I quietly moved down the stairs and sat on the third 
step from the bottom to watch the action.

Mr. Big b-lined for Eden's body, all splayed out and 
tied up. She was going to get it doggy style from me, 
but now... 

Eden yelled immediately. She could hear the dog and feel 
him covering her back, trying to penetrate her from 
behind. I pretended to run down the stairs to grab the 
dog, saying, "What the hell!" 

Eden screamed, "Get this stupid fucking dog off of me!"

I put my hand on Mr. Big's back and told him to stop, 
while at the same time pushing him on her. I told her to 
stay on her elbows and not to move down any. She was 
wiggling around trying to avoid his thrusting boner and 
I said that she was helping him and to stop.

Eden just kept saying, "Get him off of me! Get him off 
me!"

I yelped and said, "He just tried to bite me!" He hadn't 
but she was blindfolded so she wouldn't know that I 
lied. I told her I would get his leash and pretended to 
run up the stairs. Only I didn't. I came over and helped 
get the tip of Mr. Big's cock into Eden's pussy. I 
started massaging the base of his cock as he started to 
hump. 

Eden screamed, "FUCK! STOP HIM DAMMIT!"

I acted as if I had come back in and said, "What's 
wrong?" 

She yelled, "He's fucking me you idiot, stop him!" 

I said I would and reached down and I grabbed his cock. 
I could see his knot was about the size of a plum and 
right them Eden bounced her ass a couple of times. This 
caused MR. Big to hump and slide all the way into her. 

Eden cried out, "W-what was that bump?" 

I replied, "I don't know unless..." 

"Unless what? Get him off me!"

I told her that a dog has a large knot at the base of 
his cock. It was swollen up inside of her pussy to hold 
him to his bitch while they mate.

Eden was crying now, in some discomfort and asked if it 
was large enough to hold him to her. 

I replied, "I don't know?" However, from my internet 
research I knew this dog was huge and she was a very 
tiny girl so it would hold her. 

Eden groaned, "I can feel it, he was getting, larger... 
no enormous. He feels like a softball inside of me, but 
it's different, feels strange!" 

I asked her what she meant. 

"He feels huge, but kinda like a door knob. He's kinda 
barbed and feels like it wants to keep going deeper into 
me. I feel hung up on him! When will he stop?" she 
asked.

Mr. Big started to fuck Eden frantically, banging her 
harder and harder making her body shudder from his 
assault. His fucking motions pushed her face into the 
mattress, muffling her complaints. "When will he stop!" 
she cried.

I told Eden I didn't know, that my only experience was 
watching my cousin's dogs. 

Then suddenly Mr. Big growled and his body tensed. I 
knew then that he was emptying his doggy cum into my 
girlfriend's cunt. I was so hard it was painful. The 
thought of my dog cumming in Aden was such a kinky 
freaky turn-on. 

As Mr. Big strained, Eden asked in muffled voice how 
long they would stay stuck together. 

I replied, "Once, a big Mastiff stayed stuck on a 
smaller Mastiff for about three and a half hours."

She started to cry. 

I said not to worry, that Mr. Big had been fucking her 
for about ten minutes when he stopped humping her. That 
that Mastiff had fucked for a lot longer and he was a 
lot bigger.

Finally, Eden asked me to pull him off. I started to but 
she cried out, "Stop! It hurts, he's suck in me to 
much!" She said, "His knot is too big! It feels like one 
of those small basketballs, it's so huge. I don't think 
it'll ever come out."

After a while Mr. Big was getting restless and Eden kept 
moving around too. I told her to stay still, that he 
would shrink faster if she did. She wouldn't listen, she 
just kept moving around. Finally Mr. Big started to get 
up and turned around. Now they were butt to butt! He was 
taller than Eden and the angle put a lot of pressure on 
his knot. We later learned this kept the blood from 
flowing out of his knot and kept him harder longer. Oh 
well, live and learn.

After an hour Eden was pissed. "When will he get off 
me?" she cried. After two hours she was upset and crying 
that it would never end. When we hit three hours I 
started to get worried. 

Finally, after three hours and forty-eight minutes his 
cock came free. Eden was so swollen and sore that she 
was sure he had damaged her. She didn't break up with me 
- however - we couldn't have sex for about three weeks.

Eden was the first of seven women I got to have sex with 
Mr. Big. After that experience I had to see it again. 
Five of my girlfriends, my ex-wife and my ex-wife's 
sister all fucked Mr. Big over a ten-year period. 

Mr. Big died, but now I have a German Shepherd who I 
named Biggie. So far he has fucked three girlfriends of 
mine. Yes I know I have a fetish, what can I say...
