Mike's stared at his new cock. Carefully he touched his erection, moaning immediately as he sensed deep pleasure from the slightest touch.
Quickly he went to his bed, grabbing his Laptop and opened up his favourite porn-site. Starting the porn, he grabbed his throbbing erection and started to milk his cock violently. Moaning with every pull he enjoyed the feeling of his new, excess skin around his elongated shaft between his legs. It was amazing to have such a cock! His balls suddenly exploded and spurts of cum went flying over his upper-body. The first two shots even got into his mouth which he didn't care for at that moment, still entranced in his first canine-orgasm.
Coming off his high, Mike realized he'd set a timer for his transformation. He needed to make it count. His cock had started to sink back into his sheath but a couple of pumps with him watching two thick guys having a go at one-another later, he was at fullmast again. This time it took quite some effort to reach his climax yet Mike enjoyed every minute of build-up. He once again unloaded on his chest and abdomen, viscous streams of semen pouring out of his red shaft.
