[Mizu no Shinden (Punicaceae)] Koibito? wa Slime-chan [SCANMTL]

A nude woman follows a bubbling, sticky slime into a foggy rock grotto, cheerfully announcing, "I came to play," while the creature repeatedly calls that it found her. Its pseudopods become phallic and envelop her body, hauling her onto its slick mass, gripping her breasts, belly, hips, and thighs, and driving tentacle penetration until her laughter collapses into breathless squeals, "Hyaa," and warnings that she is going to leak. PuniKashia’s afterword identifies Temple of Water, calls this a first comic, and frames the hungry, affectionate pursuit around an "adorable slime girl."
