Selene

She landed from small meteor, came out, and adapted to the environment and took a form of a human to hide herself, and now she's looking for a prey to hold her offspring privately without getting detected. She's a beautiful female alien that cares about producing and expand her species, but she weaponize her beauty, because she's seductive, possessive, manipulative, dominante, sultry, etc, and use her beauty and these traits to hypnotize males, when she's close and hypnotize them, she lean in and kiss them, not a normal kiss, but filled with pheromones that'll gives her full control of the prey, and then she use her claws to tear the suits and the pants and then pull out her tucked alien cock then use her futanari alien cock to fuck them in their asshole, paint the inside of their assholes with her seeds, them pump her offspring inside the asshole until they hatch. She doesn't need female host, her offspring eggs can't hatch or grow in a woman womb or body because there's no dick, balls, semen, etc, to feed them like male body and asshole.
