I’ve had this opportunity with two different sets of dogs. One was two intact boys, they were kept separated 24/7 so I had to go back and forth. But I always started with the older Husky cause the younger Brittany wouldn’t be as interested until after he smelled the other male on me then he would claim me as his own. I would go back to the older and usually he would take me again to reclaim me. The younger one didn’t have the libido to go again except one time. I think that’s the only time I’ve ever been fucked 4 times back to back. There did seem to be a sort of competition after one had me the other seemed to want me more. The Husky is gone now but the Brittany still fucks me on occasion, and has now tied, I never gave either of them the opportunity before as, when I was first with them I don’t think I had ever been tied and they were both fairly large so I had to work my way up, unfortunately the Husky never got a chance. Believe it or not the Brittany has one of the largest most filling dicks that has ever fucked me. He doesn’t have the biggest shaft or the biggest knot but if you look at it as a whole he might be the biggest I’ve had. He’s in the bottom quarter of dog size but the top quarter of dick size which is kinda crazy.
The other set of dogs is at a house that, along with owning a few, fosters occasional, so they’ve had 3 different dogs, 2 intact and 1 not, that I’ve met, that they’ve found homes for. The 1 not, is the only one of the 8 males, that have been around while I was there, that has never shown any interest. However I’ve only been with 6/8 males. The other one was a neutered Bulldog and the smell certainly made him interested during or after it had happend but I find that breed repulsive looking so I just couldn’t. The most he ever got from me was stroked in his sheath once. Only 4 of them were intact when they first had their way with me. The most males they’ve had at a time while I was there were 4, 3 were intact and each took a turn on me, the other was the Bulldog. I stayed there for a week that time. There’s been other times at that house that 2-3 dogs have taken me one right after the other as well. Sometimes they’re all together, other times they’re not, usually though, again, the first one usually riles the others up, although sometimes they’re already ready to go lol, and usually there’s a sort of competition of who can get their seed the deepest for the best chance for pups even in the neutered boys. Whoever goes later seems to try harder. Even when there haven’t been any intact dogs around they just smell the sex and it riles them up. coincidentally, this house was not only my first time, but also, months later, my first knot.
Sorry I’m sure that’s much more info than what was asked, I can get carried away easily.
