Impregnating my bitch

I used to own a German Shepard female about 3 years ago she was my everything. We did all kinds of things together, I had gotten her when she was already a year old I watched her go into several heats I even had to put a diaper on her one year until I was drunk one night and I saw her swollen vulva, I was watching tv drinking a beer and I had my right had down by my side she actually backed into my finger an tried to massage her pussy on my fingers. At first I was horrified then I came around my drunk mind starting wondering just how much I could fit in there. I ended up sticking a whole finger in, then two then I took of my boxers and lead her upstairs to my bedroom. I slowly ate out her pussy before I worked my big dick inside her for the first time she whimpered she was so tight! but enjoyed it and made sure I knew she was having a good time! I came hard and I watched my thick white self leak out of her. This wasn’t the last time this happened many more times and I actually developed feelings for her. I had had a catheter during a surgery years ago and this taught me I can use a syringe to shoot gentle liquids into my bladder, this gave me an idea. I called up a friend whom I knew also had a German Shepard his was male I asked to set up a play date between our dogs, he of course agreed easily his dog was intact and this was a good use of him he didn’t charge me when he found out she was also gsd because I said if they had pups we would split the money. I deliberately kept them apart which bothered both of them but it gave me an added advantage. Gus the boy was very horny, he kept trying to jump all over me and mount anything he could I grabbed his dick and as soon as it was exposed I fit a confom over it and fit it over his knot and just let it collect until his dick shrunk. I then took my syringe and as crazy as it sounds, it worked! I injected Gus’s sperm inside my bladder and waddled over to my girl lady. It took a bit I was so hard I couldn’t relax my bladder to release but I know I needed too because if I waited too long my body would produce piss to put in my bladder which would change the ph and maybe the fertility. Slowly through deep breaths I quickly relaxed and sprayed it all inside her, she seemed to moan I fucked the shit out of her after and yes she got pregnant, it was phenomenal I truly felt like a puppy dad!
