The dalmatian's belly creaked like a balloon and swelled outwards again, making him whine and throb hard against it. Meanwhile, Nugget pulled open one of the bedside table drawers and retrieved something very helpful. Pascal looked over to see the ankle straps and his eyes widened with excitement.
"Wha, h-how did you..."
Nugget interrupted him: "You don't visit the Labyrinth without us knowing a thing or two about you spots~, now give me those paws..."
The golden dog pulled Pascal's ankles upwards and slipped the end of the ropes over some oddly convenient hooks on the ceiling. His rear was fully exposed now. He had only one option at this point: enjoy whatever Nugget was going to do with him and feel the egg make its way out. His manhood bounced eagerly, his knot bloated and pulsed.
"Oooooh f-fuck... This is all going s-so well..." He stammered out. Nugget crouched next to him and started to rub his belly.
"I hear creaking, but I don't see any growing... you're so close! Just look at how big and round this tummy is, think of how big that egg is gonna stretch that doggy butt!" Nugget didn't bother waiting for a response, he leaned in and started lapping at Pascal's belly button. The helpless little nub wobbled and sent the best tickly warm feelings through the dalmatian. He could feel his big taut belly tense up a bit... and the warmth in his groin grow warmer. He noticed just how stiff his dick was. Every time it twitched upwards he let out a happy little huff, knowing he could cum without any attention down there.
Then he felt it. A shift happened in his belly, a little twinge.... a familiar one.
