Oh tentacles. Organisms designed seemingly for no other purpose than to give pleasure. It’s possible such a thing could be a parasite, using pleasure to convince you to form a symbiotic relationship with it. More likely though, these tentacles were engineered with a purpose. A sexy purpose.
These cold metal halls are definitely the mark of a sci-fi setting. But, is it in space or under the ocean? Either way, a long time spent in either can be incredibly lonely and monotonous.
I think a naughty government or corporation would definitely engineer pleasure givers to aid recruitment and morale in just such conditions. Working in dangerous environments is very lucrative. Add more orgasms than you can handle to deal, and you’ve got a very compelling offer. It looks to me like May signed right up and enjoys every minute. Those tentacles probably keep her very healthy too, by excreting a nourishing cocktail of vitamins.
