The small bathroom was filled with steam as Locket finished rinsing off Brutus, the retired military German Shepherd who had become his best friend. Brutus sat calmly, his gentle and serious eyes watching Locket as he went through the motions of washing and rinsing the dog's thick fur.

As Locket ran his hands over Brutus's body, he couldn't help but notice the dog's flaccid member. He felt a mix of surprise and curiosity, but before he could second-guess himself, Brutus's eyes seemed to encourage him to continue.

Locket took a deep breath and leaned in, placing his mouth around the dog's member. Brutus let out a low groan of pleasure as Locket began to move his head back and forth. Locket felt a sense of power and control as he pleasured the dog, and he couldn't help but smirk as he looked up at Brutus.

"You like that, don't you, you old mutt?" Locket said with a wink. Brutus responded with a playful thump of his tail.

Locket continued to pleasure Brutus, feeling his own arousal grow as he heard the dog's low groans of pleasure. He reached down to touch himself, but Brutus's paw swatted his hand away.

"Not yet, kid," Brutus seemed to say with his eyes. Locket chuckled and continued to focus on pleasuring the dog.

Brutus's breathing became heavier, and Locket could feel the dog's member growing harder in his mouth. He felt a sense of pride and satisfaction at being able to bring the dog such pleasure.

Brutus released a low growl as he reached his climax. Locket felt a warm rush of seed fill his mouth, and he swallowed it down.

Locket sat back on his heels, feeling a mix of exhaustion and satisfaction. Brutus looked down at him with a gentle, thankful expression.

"You're welcome, old friend," Locket said with a smile. Brutus thumped his tail in response.

Locket stood up and turned off the shower, helping Brutus out of the tub and drying him off with a towel. As they left the bathroom, Locket couldn't help but feel a sense of closeness and connection with Brutus. He knew that they shared a special bond that not many people could understand.

Locket led Brutus to his bed, where they both curled up and fell asleep, exhausted from their shower surprise. As they slept, Locket couldn't help but think about what other surprises the future may hold for him and Brutus. He fell asleep with a smile on his face, knowing that no matter what, he and Brutus would always have each other.
