"StopMustStop!" Jared told himself. He knew the inevitable conclusion if he kept stimulating his new doggie junk.
"FeelsSoGood," he whimpered. "NoWantToStop."
Jared was a fairly typical American adolescent male and, if sucking his own dick had been an option in his old body, he would probably have been at it all the time, especially since he didn't have a long list of others willing to do it for him. All things considered, it was probably best that human anatomy made such an addiction highly improbable.
Such speculation did next to nothing to convince Jared to spit out his dick and concentrate on devising a plan to get his human body back before it was too late. He knew that, even at the best of times, getting horny made him distracted and prevented clear thought. Now, as his intelligence seemed to be sliding lower and lower, it was only a matter of time before his mental faculties dropped to the range of a normal and ever-so-dull sheepdog.
He tried to think of unsexy thoughts, but everything came back to Cassie and her breasts, which he would almost trade his soul to see again.
"DumbStupidStop," Jared berated himself even as he sucked harder at his fully-erect new doggie gear. "OhNo!"
Jared felt the sudden release as his new equipment pulsed and flooded a load into his mouth. He gulped and swallowed, even as his just-exploded dick pulsed again and sent more cum into his mouth. Some of the load seeped from the corner of his mouth as his eyes took on a glassy look of dumb contentment.
When Cassie came to check on him a short time later, she found the sheepdog sleepy and docile, not his usual alert, playful self.
"You've been quite all evening, Shaggy," she said. "What have you been up to?"
Shaggy heard her speak to him, but the words were mere sounds backed by the mood of the speaker. Cassie's sounds indicated a pleasant mood, which made the canine feel secure in her presence. "ShaggyLoveCassie," the dog panted and looked at her with dull, glazed eyes obscured behind a fringe of overflowing fur.
