Porn Game: N.i.P. - v1.5.4 by Lapsa

In N.i.P. (Short for Nal in Peril), you play as an Avali named Nal who has to make their way off of a ship infested with parasitic tentacled lifeforms that seem undeterred by a lack of willingness. The second half of the game turns more towards a diverse range of things, though mainly featuring hypnosis as Nal further fights to escape the creeping claws of lust threatening to grip them forever in its embrace.
