Under the right circumstances, of course! Ideally in a foreign country with other like-minded folk who I had never met before. It would take a considerable amount of planning and, of course, trust.
The only rules are no cameras, everyone has to be naked, and any personal contact has to be by mutual consent.
There would need to be several male dogs and at least two male horses. It would start with 2 women first getting fucked by horny dogs, who would later sit on my face while I sucked the doggie cum from their cunts.
Inke, are you reading this? 
Then it would be my turn to get fucked by 2 or 3 dogs in turn. While the first dog fucked me I would fuck one of the girl's wet cunts that I had sucked before. When the second dog fucked me, the other girl would suck my cock until I emptied my load into her mouth. Perhaps one of the dogs would fuck her again while she sucked me. If another dog wanted to mount me, that would be fine. My arse would be stretched and well-lubed by then.
Later, I would suck one of the horses until it exploded filling my mouth with cum.

BTW, horse cum is very nutritious and is offered in a shot glass in some pubs in New Zealand.

Shortly after I had finished my horse cocktail, an adventurous young woman was preparing the other horse to enter her by first slapping his long, soft cock against her clit.
This event is so well planned, the organizers have some new dogs that had not emptied their balls earlier waiting to be brought in for those participants who are ready for round two (or three)! The smell of dog and human cum everywhere was enough to get these dogs excited, and their cocks were out and they were ready for some action. After resting while watching some other people experience their fantasies, I was ready to suck some dog cock. Personally I prefer the taste of horse cum, but by now I just wanted to satisfy
all my
uncontrollable desires.
