[M4F] Losing my girl to the dog

I suspected something was up when we first went to pick up King. Sarah had been persistent in wanting a dog, and I had finally caved in to my young wife's demands. She argued that I was constantly gone on travel for work and she needed someone to keep her company. Not only that, but there had been a recent string of burgleries in the neighborhood and a dog, especially a big one, could thwart any potential intruders. I wasnt really much of a dog person, I'd always been bad at getting them to listen to me or take direction. But I gave into her desire and found myself at the pound. We looked around until she found the dog she wanted. He was some type of mastiff/dane mix, and he weighed 190lbs the shelter worker told us. "Great," I thought sarcastically, but I had already promised Sarah she could pick any dog she wanted. The worker told us we could have him neutered before taking him home, but Sarah chimed in quickly to say that we didnt have time today but would certainly come back. I interjected that we didnt have anywhere else to be that day, but she cut me off. "Whatever..." I thought.

King, which is what she named him, walked ahead of us out the door and too the car. I couldnt help but notice the dog had massive testicles as he walked in front of us. They swayed back and forth like billiard balls. I looked over to Sarah to make a joke, but stopped when I realized that she was also staring intensely, eyes transfixed on Kings package. We walked in silence as she kept staring down between his legs, at one point swallowing loudly.

Although it took me a while to notice, that was the day things changed. Sarah was immediately very attentive to the dogs needs, taking him for frequent walks, spending all her time on the couch snuggled with him and watching movies. The two had become inseparable. They seemed to communicate to each other with looks and body language in a way I couldnt understand, but it seemed like Sarah always preemptively knew when he was hungry, when he needed to be let out, when he wanted something. The first time I became suspicious of something was a day I got off work early. I came through the door shouting that I was home, but there was no reply. I went to the bedroom to see if Sarah was asleep, but what I opened the door to made me confused. Sarah was standing up in nothing other than an oversized tshirt. Her cheeks were flush and she seemed to be breathing heavily. She approached me smiling but nervous and asked me how my day was and why I was home early. I picked up a faint musk on her breath. It was salty and sort of smelled like wet dog. Thats when I noticed out King sitting on the bed, head stuck between his legs licking his dick. That was the first time I saw Kings cock, and it startled me honestly. It had to be at least 8 or 9 inches long, and thick with a blunt tip. It was red and veiny and swollen.

Sarah and I got on about our evening, but I knew something was up with her and that dog. I highly suspected she had been jacking him off or something. I figured she had no ill intent but had grown so attached to King that she felt it her responsibility to service his need. I rationalized that vets did it from time to time...But before I could confront her about it, I needed more evidence. So my next work trip I decided to hide a camera in our bedroom.

On the weekend of my trip, I made it to the hotel room and rushed to open my laptop to see what Sarah and King had been up to and to see if she was indeed "relieving" him. What I saw was so much more than anything I could have imagined. At some point, Sarah and King walked into frame. Sarah had a leash in hand and knelt in front of King, putting her hands on his collar. God, she was so small next to him...he was sitting and she was kneeling, and his jaw could rest flat on top of her head. She was unbuckling King's collar and then slowly put it around her own neck before clipping it shut.

She tilted her head up to King looking into his eyes, "Only with the collar on, right?" King was silent as he stared back at her and let out a low rumbling growl. Sarah then took the leash and looked the end through the handle, throwing it over King's neck like a lasso. Then she took the other end and clipped it to the collar around her neck.

Holy. Fuck. I couldnt believe what I was watching. I had an instinct to call her and tell her to stop, but then I remembered this footage was over 10 hours old at this point and it wasnt even clear she was home right now. King began walking around the room, towing my beautiful girlfriend around behind him like some pet. Eventually he stopped and laid down and Sarah laid with him. Ahe crawled over to his backside and with surprisingly little hesitation planted her face I his ballsack, with her hand reached around on his shaft. She began making out with the dog's testicles while stroking his inflating cock. At some point, she leaned over and put the fat tip of his doggy dick against her lips and teasing him a bit before sliding as much of his length as she could into her mouth. She was sucking the dog better than she sucked me.

Eventually King abruptly stood up and walked away, tugging Sarah out of frame with him by the leash. I didnt see what happened next but I heard everything. First the clumsy jingling of the leash and collar on her neck. Then a whine from him and a moan from her followed by the wet sounds of sex. It was clear to me that King was fucking my tiny gorgeous wife. Sarah was quiet with me but loud with him, moaning about how good his dick felt. Then she started saying things I didnt expect. She kept saying that she was sorry over and over, and I assumed it was because she felt guilty for me. Until she said plainly, "Im sorry King, I think Im gonna cum. I don't wanna cum, I wanna be a good girl! Im sorry King I cant help it. I know you dont like when I cum but youre gonna make me. YOURE GONNA MAKE ME." Sarah's groans filled the room and I listened to her orgasm on Kings doggy cock. She came down from the high simply repeating, "I'm sorry king...i wanted to be good for you."

Well at this point I feel like I dont have to say much. Im looking for a woman to be Sarah! No worries if youre new to dogs, I love all types
