like in particular dogs, are their holes be stretchy enough to dont feel pain?
As long as the dog is big enough, and comfortable with it, no. For example in my case, a male german shepherd's cock is significantly larger, harder, than mine and he'll usually just ram that thing in her until it swells and sticks. My little human dick isn't going to hurt her, she loves it.like in particular dogs, are their holes be stretchy enough to dont feel pain?
