Wifes Pussy is the Perfect Bait

My wife's parents were going on a trip for four weeks and asked us to look after their small acreage while they were away. We jumped at the opportunity to take a break from work and a few weeks later we were on their doorstep ready to look after the place for them.
They gave us a good look around and showed us everything we needed to know which was all pretty straightforward. Cheryl's dad Jim made sure we knew to keep the chicken yard closed up at night due to the wild dog problem. He said they had eradicated almost all of them but there was still one or two that were proving hard to deal with. We assured them we would take care of everything and I told him that I may even try to trap the remaining dogs. He laughed at this and told me that they had tried everything but the dog was very cunning and so far had evaded all of their traps. They had seen one of them even come into the yard during the day when they reviewed their security footage and helped himself to one of the chickens.
We had a few uneventful days in the first week and then one day as I was looking at the monitor I noticed a large curly haired grey dog moving along the fence line towards the chicken coop. It was moving very slowly and taking its time to look around before proceeding steadily towards the open yard of the chicken run. Cheryl's parents had installed cameras above the chicken yard so I clicked the mouse a few times until the yard came into view. I almost freaked out when I saw Cheryl was in the yard on her knees reaching into the hen house to collect the eggs. I had no way to alert her about the approaching dog and decided that he would probably be scared off once he saw her. The big animal turned into the chicken yard and seemed to not notice Cheryl, he was looking for a sleepy chicken and silently worked his way around the inside of the fence until he reached the edge of the coop.
The big hairy dog suddenly noticed that there was another presence in the yard and approached Cheryl cautiously as she still had her head and shoulders inside the coup. He didn't seem too concerned as he sniffed at her feet and then moved his muzzle to her arse and pussy area. Even with her skirt and panties on he seemed to know what lay beneath them as his huge cock had slid out of it
s sheath and was dangling halfway to the ground. He got a bit close with his nose and it came into contact with Cheryl's leg causing her to jump with fright which in turn panicked the dog and he ran out of the yard before she was even able to lay eyes on him. Somewhat started she came up to the house to tell me what had happened and I explained that I had seen it all but didn't have time to warn her. I told her that it must be the dog her father had told us about and she agreed. I explained to Cheryl just how attracted the dog had been to her scent and how he didn't seem threatened while she couldn't see him. I wanted to catch the animal and destroy it before her parents came back so I could get some bragging rights and Cheryl agreed to help me.
We watched the chicken yard for the next couple of days and observed to dog returning like clockwork each day. Each time he only spent a very short time in the yard and there was no way we would be able to sneak up and shut the gate in time. We need to keep him in the yard long enough to have any chance at all. I suggested that Cheryl might bait him again like the first day when he showed interest in her. (I didn't tell her about the dogs massive cock though). She was hesitant at first but when I explained that he seemed to have no interest in harming her she agreed to give it a try.
The next day she wore a short skirt and left her panties off as I suggested it might help distract him long enough for me to close the gate behind him and enable her to then crawl into the chicken coop and make her escape through the external wooden door. She was to wait until she heard the gate shut before crawling away from the dog and the hard part for her was to try and remain still if his nose got too close again. Cheryl went down to the yard again and took up position as planned while I watched the monitor in the house for any sign of the dog. Right on time he appeared and snuck closer to the yard before taking a last look around and creeping inside where his keen sense of smell alerted him straight away to Cheryl's presence. He once again sniffed at her rear end and his cock snaked its way out of its sheath again. The hairy beast took more care this time and was keeping his wet nose away from making any contact. With delicate precision he took her skirt between his front teeth and carefully lifted it over her hips exposing her nakedness to the open air. Cheryl was doing her part to remain calm and didn't move at all as she felt her skirt being lifted. There was no gate closing sound yet and she was staying motionless just as planned. I made my way out of the house and quietly headed for the chicken yard, when I reached the gate I looked around the corner of the post to see if the dog was still in the yard. He was still sniffing at Cheryl's exposed pussy and I resisted closing the gate as I wanted him to move away from her before doing so. I figured he would move on shortly and then I would have him trapped while Cheryl crawled through the coop safely away from him.
After seeing no movement from the pale skinned hairless pussy that he had now exposed the dog flicked his tongue out against the smooth folds to taste the tail less female in front of him. As confused as he must have been, he knew full well that the warm body was female and his cock was twitched excitedly as his sensitive tongue tasted Cheryl's slit. She didn't flinch as his tongue probed deeper between her flaps. She did not want his sharp teeth anywhere near her when I closed the gate and made me promise to wait until he was well away. We hadn't factored on him licking her cunt but we both held our nerve as he explored her with his long, wet tongue. I could see well enough to know that his licking was having an effect on Cheryl, his tongue was a pushing couple of inches inside her each time he lapped at it and she was not only wet from his saliva but also her own juices had started to flow prompting him to lap them up at a faster rate. The dog was moving his weight from foot to foot growing increasingly agitated as his thick cock hardened. Satisfied that the wet hole was wet enough he withdrew his tongue and mounted Cheryl in one quick movement and his bright red rod slid inside her cunt before she even knew what was happening.
This wasn't Cheryl's first dog cock but it was certainly the biggest she had been injected with and this was a wild dog that only knew one way and that was hard and fast. He thrust his pelvis into her until his thick cock was no longer visible and then humped against her arse as his cum pumped into her until it overflowed out of her pussy onto the ground. Cheryl moaned as the dog fucked her to orgasm before his placcid cock slipped out of her and slid back into its sheath. Cum continued leaking out of her as she stayed motionless. I expected her to crawl to safety but she remained motionless as the dog turned away from her and came towards me and the gate. I hid out of sight and watched as he left the pen unhindered.
I went to Cheryl and asked why she hadn't gone into the coop and she replied that she wasn't sure where he was and thought maybe we should try again in a couple of days? The big dog fucked Cheryl on six occasions during our stay until finally we locked him in on the day before her parents retuned and left him to them to deal with him. Before leaving we offered to return again if they had any other wild dog problems they needed help with.
