My Girlfriends Dog Licked My Feet While I Was Having Sex

Last week after a night out of drinks. We went to my girlfriends apartment because her roommates were out for the weekend. Things got hot and heavy, my girl is super horny when she’s drunk. She couldn’t wait, she stripped of my clothes and laid on top of me, riding me. I was really into it, until her dog walks in. Not the first time her dog is in the room, while we are having sex. His name Ranger. She is riding me, we are both into it. Until her dog starts licking my feet, I try to ignore it, then I kept moving my feet away. But her dog doesn’t stop. I start squirming, and couldn’t help but giggle lightly. My girlfriend asks what’s wrong? And I tell her, through light giggling, “Ranger is tickling my feet” she shoos him away. And we continue to do our thing, my girlfriend decides to blow me and I’m really into it, she was sucking me good. And I feel his tongue between my toes, and i jumped from the reaction. Ranger goes to my other foot, does the same thing while I’m getting a blowjob. Next thing I know, I’m giggling and moaning at the same time and I just blow a load, laughing, wiggling my feet away. She sees the dog licking my toes, before she jumps off me she quickly drags her nails on my balls, and i nearly lost it. That was that lol

I would have been quite angry at the dog.
<=== son-of-a-bitch

I'd probably start locking the bedroom door.. lol

Do you think she trained the dog to do that?
