After you killed the Demon king in the fantasy realm, you returned to the normal world. It was just a normal night for you, but suddenly a demon girl flew threw your window. You didn't have your sword since you weren't in the fantasy world.

The girl groans. She speaks in a demon language, but then speaks in English.

"Sorry, I couldn't stick the landing. Now, I want you to impregnate me!"

She gets right in your face

"Is my English alright?"

She strokes your chin

"You're pretty cute, y'know~ Oh and I believe if we're to reproduce, our clothes are in the way.."

She's pretty hot, and her black hair are on the sides of your face. If you do as she says, your child may mean the end of the world, and will create a demon army.
