Licking the split or knot

You already know that my wife Wendy, loves cock and cum that she likes being used, and having strangers cop a feel and more, and you know that she blew her load when our German Shepard jumped up on the bed when she was tied to it, and licked her bald wet pussy inside and out.
I found that experience to be profound, it shook the very foundations of my boundaries, and a whole new level had been opened up, it took a couple of weeks before the buzz started to wear down, in truth I wanted to tell my friend, I wanted to share what had happened, I didn't of course, fear and a sense of shame ruled my mind.

Wendy didn't speak of what happened either and I presumed that she too was thinking about what had happened, of course, I was wrong, I couldn't have been further from the truth. My wife was actively seeking others who were into that scene, that night had turned her on, it had lit a fire under her, and she wanted to explore the whole world.
She found a site where another woman around her gae was willing to talk, just not on the Internet, if Wendy wanted information she would have to meet the lady in private, a day and time were worked out for the meet.

They met in a park, sat on a bench and got to know each other, Wendy learned the dog the lady was walking in the park in front of everyone was the very same dog licking and fucking her, that turned Wendy on, right under their noses and they were none the wiser.
The lady said there was one thing that had to happen before she would openly talk about what Wendy was after, she asked Wendy for proof of what she was talking about, she already new the story that started it all, but that wasn't enough, she told Wendy to think about it and give her a call when she had made her decision.
I got home from work without knowing anything was going on, I was in fact at that point completely in the dark about the whole situation. Later that night I went to bed while Wendy watched the TV, after I had fallen asleep, Wendy called her friend and said she was willing to prove herself, she went to facetime the lady who told her no they didn't do that either, she asked Wendy for our address and said she would be around.
Sometime later the lady showed up, Wendy met her at the door with Max and showed her in, they talked and had a drink, the lady said is there somewhere private they could all go, Wendy led the way to a spare bedroom, the lady closed and locked the door, she then said to Wendy strip off, I want to look at you, Wendy did as she was told and stripped, the woman smacked her bum, felt her tits, and dipped a finger and tasted it, perks of the job she said, then she pushed Wendy onto the bed spread her legs and started rubbing and fingering Wendy's pussy, then she put her fingers near max's nose and he licked them, she repeated the process a couple of times, then led max to my wife's bald wet pussy, max started licking her pussy, Wendy spread her legs wide, the lady reached under max and began to fell his cock, it was beginning to come out. When his cock was fully out the lady pulled max away from Wendy's pussy and told Wendy to sit up she said I want you to feel max's cock reach under and feel it, explore it, see how big it is, Wendy reached under max and began exploring his cock, she said it was big, and it did feel better than she thought it would.
She got Wendy to stroke his cock to see how wet it gets with precum, she told Wendy to taste the precum, Wendy licked her fingers to her surprise it tasted ok, the lady said now I want you to suck his cock for a while, and I mean you suck it, right in you taste it and you take it. Wendy bent right down and got in position with the lady watching opened her mouth and took our dogs cock in and began sucking it, they took turns sucking his cock which had begun to leak a lot of cum, of which both girls sucked up.
The lady got on all fours and max was put in a position to fuck her, the lady told Wendy she was to watch and see how it was done, max was guided into her pussy and he fucked her, eventually as the lady explained she said the knot was now inside her and it was beginning to pump cum into her, she said it was a big pressure feeling but nothing that would hurt her, cum began to leak out as she was being filled, they stayed coupled together for about 5 minutes before the knot went down allowing max to pull out, and when he did the cum flowed freely, he had done his job and bred.

The lady told Wendy before she left that Wendy should pack a bag for a four day weekend away, and she would ring her with the details in a day or so, she also told my wife, to keep max active and let him have all the pussy he wanted to lick and fuck, she said he will want to fuck now that he knows he can breed you.
