The muscular spasm works its way from her midsection to both sides of her body, a rippling crushing shiver that hits her tailtip and bounces back. No longer able or willing to hold herself back, the walls of her belly finally respond with all their force against the slimegirl provoking such pleasure as Eurikova climaxes- juices from one orifice matched by juices oozing from her stomach walls. The naga yelps a little, sagging limply inside her own coils and dragging those up to curl around herself as if she were a meal for herself. Relaxing half-stuporous in the aftermath of her own orgasm, she either can't or won't control her muscles very well; the churning pressure gets steadily more intense, kneading Phylia more and more tightly, pushing her deeper into the naga instead of closer to her mouth and freedom, all the while her acids try to thin the slime out into something her intestines could more easily absorb.
