Pascal could feel the phantom kangaroo member throbbing in his rear, Cuda was off nearby somewhere with his voodoo plushy and humping the daylights out of it. He looked down at his belly knowing it was gonna happen, then with a sudden flooding warm feeling he watched as it rounded out quickly. In the blink of an eye he grew tighter and tighter... and then pop! His belly button was pushed outwards with force. He relaxed back as the final bit was pumped into him, the poor dog looking like his tummy could burst at any moment.
I'm planning on adding his spots and coloring this, but it will take time. I also expect to do another one of these but longer, so I'm not sure if I'll wait until it's finished to release it or post wips.
