I agree with someone else who said they love their dogs. I love mine to pieces just for being pets. There are two who would never let me touch them and I wouldn't want to. They are amazing. I'd say for me it is more of just a kinky thing, I do LOVE my dogs but not exactly romantically. A girlfriends emotions for me do not compare to a dog. However, with my 1 dog when I lay on the bed and he comes up and stands over me without prompting and I jerk him and suck him, he stands without being held and I already love him (not romantically) it is a really cool moment. One time and one time only he came over and started nuzzling my crotch. There was no sexual buildup or the usual "pat my thigh and strip" routine, this was out of the. Blue (he's cum obsessed lol).
As far as the sex, I find cum a huge turn on, and we'll dogs just keep going. So that's awesome, they have nice huge dicks. Also when they fuck and cum, I'd take it to say they are enjoying it, which some may just say it's instinct but I don't know where instinct comes into play when a male dog willingly stands over a male human to get jerked off (im not gay either btw lol yet here i am). So much commercial porn is faked orgasams, when a dog cums he's having a good time. So the real aspect of it is a huge turn on. The taboo part is also sexy. Seeing girls do the act, you really have to give total control to the dog, I'm kind of into bdsm and the fact that you are sumbittting and trusting the dog (for me the trust aspect of bdsm restraints builds more intense bonds between humans). I do not support any bdsm with animals to be clear. Plus again, the cum thing. Huge cum fan. Also the fact that it's just so dirty, and if I get into a relationship with a girl, well idk it's hot that we would do it and no one else would know I guess. So I'm in it more for the sex but again connecting with an animal that clearly enjoys it is something special, a 3 way with a good girl and amazing dog would be out of this world
