Summary

Deep in the forgotten forest, verdant growth shrouded the decrepit remains of a tribal temple... a dwelling of dreadful violators! Coiling tentacles constrict heroines in an orgy of hellish ecstasy. A grand journey & tentacle assault AVG! The archaologist "Prof" (main heroine), joined by her plucky, tomboyish assistant Akari and her cute friend Fanita, pass through a culture portal via these ruins. Inside they discover its lascivious secret... The ancient civilization of Sotisthunra erected this sexual altar for the sake of the sprawling spermexa that lay dormant...! These girls may have discovered great history, but will they survive it!!? [From DLSite English]
