Being licked in odd places

So this morning my boyfriend and I where having sex doggy style and right in the middle of it my dog started licking my toes.. my feet were hanging off the bed a little, It was very uncomfortable I actually had my boyfriend stop so I can put him in his kennel so we could finish. And I'm kinda werided out that my boyfriend let our little dog come between his legs and let him actually be that close to everything going on down there. And Another thing that's kinda freaky is I guess according to my boyfriend my dog also sits there and watches it all happen from the beginning to the end.. idk what to think of it I'm kinda grossed out 😕 anyone have this happen??
