In the retro sci-fi world of Tentacle Nest, a pin-up girl named Gwen Tennyson, reminiscent of the Ben10 universe's ultra characters, is found in a damaged spaceship. She's dressed in a torn, white and chrome space outfit, revealing her tanned, glossy skin. The alien tentacles, slithering through the ship's depths, have discovered their next conquest: Gwen. With a look of surprised pleasure, Gwen is being pleasured by these extraterrestrial appendages, her body covered in a sticky liquid that drips from her mouth, ears, and floods the floor below. The sight, captured in HD quality with intricate details, is a bright orange and green spectacle under the soft tentacle light.
