Videos of couples and dogs question

[curiousbeast]

I've seen quite a few videos online of mf couples with a dog (amateur and professional) but every single one the guy starts out and fucks the girl for a bit before the dog enters and gets his chance. After the dog mounts successfully or not the guy never does anything with the girls ass or pussy from that point. The dog fucks her until he finishes while the guy gets a blowjob. Once the dog pulls out the girl usually starts sucking the dog and that is it for the guy. The guy never does anything else with the girl, it's like she has the plague. Why is that?

Does it have to do with the girls pussy after getting knotted? Like it would hurt her if a guy started sliding his cock in right after the knot popping out.
Or does it have to do with something with the dogs cum? Like if a guy came into contact with dog cum he could get an infection of some kind.
Or would the dog become aggressive if a guy tried to fuck the girl after he did?
Or is it all on the guys that are involved? Like they personally find putting their cock in somewhere a dog's cock has just been in absolutely disgusting.

I'm extremely curious. I've never seen or have been involved in any beastiality acts in person (only because I've never gotten a chance). I just don't see how someone that gets the opportunity to enjoy having sex with animals wouldn't treat a threesome with any animal like they would if it was with 2 guys and a girl.

I love going back in after Our Pup is finished, nothing like a good wet squish!, yeah I know this is old.... but I was shocked it never got a response.

Lol it's because nothing compares so a dog.....that a human afterwards is like an insult XD although I'm partly serious because I have no definitive answer; if I was in a three some and a dog just mounted me I would be set .... anything else with a person would be oral because being mounted and knotted is the best feeling in the world. There just is nothing that can compare.
