Taking a deep breath, Kirk pushed his butt backwards, splaying his hands on the stones of the alleyway. His asshole clenched, the nub of his tail pulsed like a hard-on, and in the front of his shorts, a similar feeling surged through his cock as it rapidly rose to full attention again.
This was going to be terrific... He was going to sprout a tail - a LONG tail! - right through the seat of his white shorts. Mitch's had been so sexy as it punched its way free, long, naked and virile, and he couldn't wait to experience the same sensation. He just wished there was someone with a camera who could...
"Whatcha doin?"
Startled, Kirk turned his head to see a young lad with slightly pointed ears, who had come out into the alley with a beerglass in his hand. He was staring at Kirk's butt with total fascination.
"Erm...I'm..." The fly half hesitated, and then a mischievous grin spread across his face. "I'm sprouting a tail," he said easily. "I'm hard as a rock, kid, and I'm sprouting a donkey tail..." As he spoke, he put one hand behind him to stroke his shorts-clad butt. "Wanna watch?"
The kid stared at him for a moment, then, grinning broadly, he took a quick swig of his beer and strode up to Kirk, one hand tugging on the front of his own shorts.
"Sure," he said eagerly, and standing right behind the tawny-haired rugby player, added, "Go for it!"
