I absolutely love your scene idea, and I think it would be incredibly hot as a "co-topping" session in which a Master/Mistress "breeds" his/her "dogs." Yep. I'm so into it.  Even better if the canine doing the penetration is in fact a lovely female.  

Ah! This would be SO MUCH FUN.  

Thank you for sharing! I love ideas like this.

Two guys are sitting on a park bench. A stray dogs walks up and plops down in front of them. And as dogs will do he starts vigorously licking his private parts.  

One guy wistfully says to the other "Gee I wish I could do that"  

The other replies "If you pet him and ask him real nice maybe he'll let you."
