It’s a beautiful sunny Sunday. Mistress is out in the forest walking her dog. She lets him off the lead so he gets to exercise a little. She throws him a stick, asking him to bring it back. Doggy brings it back but resists to give it back to Mistress. Mistress realises that she might not have been hard enough on doggy’s training. She gets the stick back and tells doggy to sit properly. She scolds him for not listening to her and orders him to stand against the rock. She puts her gloves on, and laughs perversely. She repeats “I trained you to bring back the stick, didn’t I?”. Doggy is just starting to understand what is coming his way. He is begging Mistress to let him off, whining like a puppy and licking her hand. Mistress tells him that it’s just not good enough. She pours lube on his ass and sticks her fingers inside of it. She proceeds to inserting her whole hand until her black glove disappears inside doggy’s butthole. Mistress takes off her skirt and puts on her black strap-on. She tells doggy that her whole hand inside his ass will not be enough, that he needs to feel her big black cock inside of him too. She takes him from behind against the same rock like the dirty dog he is. Doggy is clearly regretting having disobeyed his Mistress. He is whining and making way too much noise so Mistress gags him. She lays him down on top of the rock and pounds him with his legs up in the air whilst he is holding on to the bark of the tree behind him. Finally she makes him clean her strap-on that has just been inside his ass with his mouth. She throws him the sticky stick one last time. He brings it back. He’s clearly learned today’s lesson and Mistress pats him on the head to congratulate him.
