The people not understanding what exactly was happening became angry as they were shoved away by the expansion and began to push back. They placed their palms on the smooth skin and pushed into it, their hands sinking into the soft warm to the touch flesh as they tried to press it back underneath Fey, pressuring what was inside and in so doing stimulating the sensitive body around it. The faint muffled pleasured howls of Lily could just be heard as they essentially massaged and squashed her cum belly, but it would take someone really paying attention to hear it over the crowd.
Fey's eyes fluttered as she felt the pressure of her own cum swirl around her length, squeezing down on her shaft. This of course just caused her to cum all the harder.
The crowd was fighting a losing battle by this point despite a dozen people joining together to heave back against the strange liquid filled balloon and they were gradually being pushed backwards and pressed against all the others packed together in the small area outside the AG. In fact the crowd was so packed that many of the people were left pressed tight against the otterkin's belly, their arms spread out over it, their faces smooshed up against the surface, not knowing that just below the surface was a lake of boiling hot horse cum, only Lily's stretched thin flesh separating them from it.
Fey shivered as one last surging spray of cum went into the otterkin and her expansive belly lifted her hooves an inch up off the ground, the centaur supported entirely by the gut of the otter girl. She gasped and trembled and panted as it came to an end, having to lean down and grab hold of the shoulders of two people in front of her to support her limp upper body. They gave her annoyed looks. A faint muffled scream could be heard and a small stream of Lily's juices flowed down the back of her dome of a belly, soaking the people who were pressed up against her on that side.
"Er, maybe we should have waited until we were somewhere a little more private for that," said Kayla looking around nervously at the belly bulging out from beneath the centaur that the crowd was pressed up against.
"Y-you think!?" panted Fey between heaving breaths. "What am I gonna do Kayla! I'm trapped like this!"
"I don't know!"
They were interrupted from further discussion however by Flora letting out a gasp.
The gnome was looking down at her belly in extreme alarm.
"What is it Flora?" said Ellaria emerging back out from the AG.
"It's coming, oh gods it's coming out!"
Ellaria furrowed her brow in confusion.
"What's coming out?
"The slime! I'm going to give birth to the slime right now!!!"
