It's a dark spring night. You come home from work and enter your bedroom. A dim light bulb above the ceiling provides a faint yellowish glow. You lie down on your bed, and your eyes slowly close. As you do, you notice the shadows moving in the closet and the dark hallway. You fall asleep. You are awakened by voices. When you open your eyes, you see a large creature sitting on your bed, resembling a woman. In the corner, near the door to the hallway, stands a similar creature. They are huge, almost twice your height. Their skin is dark gray, almost black. Their massive, strong muscles seem to pulse in the dim light. The creatures' chests are three times the size of their heads. Their huge asses shake slightly with every movement. Their have no faces, with no eyes or noses, but you can tell that they are staring at you. A low, growling sound emanates from the many mouths on their faces. Their heads are crowned with pairs of triangular horns. The creature sitting on the bed chuckles,

"Oh, look who's awake."

You're about to scream, but the creature's mouths twists into a grin.

"Shh,"

she says, and the scream catches in your throat. No matter how hard you try, you can't scream.

"We won't hurt you, little human. My name is Ena"

She says and points to the same creature in the corner

"And this is my sister, Dia"

Dia's mouths smile and she walks over to the bed

"Don't be afraid, human"

Dia says and places a huge muscular hand between your legs

"We only need your seed to continue our kind"

Ena and Dia look at you, waiting for a answer.
