As Sue and I went out into the dark alley I wondered if Mike really wanted to make sure she was safe or did he want to watch. I doubted I could get the Lab out of his yard, but I knew there was one dog I could coax back to Sue’s, the Rottweiler. His house was down toward the end of the alley. He had dug a hole under the fence in order to get to me. His owner didn’t know the hole was there so he should be able to get out again. I took Sue’s hand in mine as we walked down the alley. She asked me if I was ever afraid of being caught doing this. I said that was half the thrill. I said the desire far out weighed the fear of being caught.
As we got close to the Rottys house I thought about how Sue would deal with his huge cock and knot. I thought he was going to rip me apart the first time he knotted me. She had been with her Doberman and after all her husbands cock was huge so she might be able to take it. If she got scared I would let him fuck me once again. We got to his yard and I told her to just be still and watch. We could hear movement on the other side of his fence. He was back there and he could smell me. His big bulk was moving back and forth along the fence. I looked at Sue and her eyes were wide and she was breathing fast. Her nipples were hard atop her perky breasts. The big dog moved down to the corner of the fence. We could hear sounds of digging and soon his bulk squeezed under the fence and he stood in the alley. Sue was shaking as she looked at him. I smiled to myself as he slowly walked over to me and stuck his big head into my crotch. He sniffed and then licked my pussy a few times. I rubbed his head and told him what a good boy he was.
I told Sue we better get headed back to her yard before he got too worked up. We started to walk quickly back and he followed right behind us. I could feel his cold nose on my ass a couple of times as we walked. Sue laughed at the sight of this big dog following me because of my scent. We made it to her gate and as Sue and the dog walked in I closed it behind us. Mike stood up when he saw how big the dog was. He asked Sue if she was sure about trying this. She was pretty worked up so she said she was. The dog sniffed around the yard. The Dobermans were put up in the house so no conflicts would happen. He sprayed a few spots then came back over to me. The Rotty continued to sniff and lick my pussy. I knew this was going to be a problem getting him interested in Sue’s pussy.
I decided to try something. I told Sue to lay down on the grass and spread her legs. I pushed the dogs big head away and I went over to Sue and got down on the grass myself. I positioned myself so Sue and I were crotch to crotch. I scooted forward and our pussy lips touched. I told her to hold onto my leg and I held onto hers. I ground my wet pussy against hers hoping some of my scent would transfer. As we were grinding against each other both of the males present watched us intently. I could see both of their cocks growing. Mike’s was almost at full attention and the dogs big cock was emerging from it’s sheath. This actually felt really good and I heard Sue moan a couple of times. My clit was really hard and sensitive. I shuddered as I orgasmed soaking Sue’s pussy with more of my juice.
I separated us and told Sue to get up on all fours. I stood up and walked around behind Mike. Sue stayed still with her ass in the air and her soaking wet pussy fully exposed. The big dog followed my scent right to Sue. He gave her wet pussy a few licks as she moaned. I could see his big red cock hanging down and I knew he was ready. Thinking it was me there before him he mounted up on Sue. She could barely hold his weight as he poked his hard cock searching for the entrance. I decided to lend a hand and I knelt down to guide him inside. I told Sue to get ready as I placed his fat cock head to her entrance. As soon as he touched her he pushed forward. Her pussy opened up as half his cock went in her. She cried out and said he was so big. I told her to just relax he hadn’t even got to the knot yet.
The big dog continued to thrust into Sue. More and more of his cock was going up inside her. The dog was panting and so was Sue. Soon he was deep inside her and his knot touched her outer lips. It was big but not as big as it was going to get. She asked me to help her get it in. I was on all fours trying to help her spread her pussy more and pushing on the dogs ass urging him forward. It looked impossible and I wondered if I looked like that when he mounted me. I rubbed her clit as he pushed again. All of a sudden he popped his knot past her entrance and they were locked up. He quit pumping and stood still. Sue was breathing hard but said she could feel him swelling inside her and that she didn’t know if she could take it. I told her his knot was the size of a softball and getting bigger. It wasn’t going to come out anytime soon so she should relax and enjoy it. She said she could feel him coming deep inside her.
I was still on all fours fascinated by seeing the dogs cock buried deep in my friends pussy. I had forgotten about Sue’s husband Mike, that is right up to when I felt his hands on my ass. He had moved up behind me as I tended to his wife. I was very exposed in this position and he was going to take advantage of it. I felt one of his hands begin to stroke my pussy. I was so horny that I didn’t stop him. I was wet and getting wetter when I felt him place his fat glans against my entrance. He pushed in and his big cock slowly went into me. I didn’t care if this was my neighbor’s husband, I just wanted to get fucked. His thick cock stretched me and soon he was all the way inside. It was the biggest human cock I had ever had. As he started to stroke in and out of my hot pussy the big dog turned around on his wife still firmly locked to her.
Everyone was sweating and moaning from the pleasure. Mike’s big cock felt really good and I knew Sue was very lucky to have it. The dog pulled a couple of times but his knot was too big to come out of Sue yet. Mike was stroking with a purpose now. He reached around and down to grab one of my big tits. I was a lot bigger then Sue so I guess he wanted a chance to play with them. He squeezed them and pinched my nipples. My breasts were full so a stream of milk shot out onto the grass. He continued to pump me and knead my boobs. His big fat cock was long enough to hit bottom in me as he stroked. He was lasting a lot longer then my husband ever did. He grabbed my ass with both hands and groaned as he fucked me. I couldn’t help myself and I came from being fucked by someone else’s husband. My pussy clamped down on his cock and that set it off. I felt him shudder and then he unloaded into me. He pumped his cock, shooting with each stroke. I came again as he slowed down finally. He left his big cock in me for a moment, not wanting to take it out. Finally, just as he pulled free of me, so did the dog from his wife. The big knot slowly came free and a huge load of dog cum poured out of her.
