A knock at the door

As you're getting dressed, you hear a knock at your door. "Who is it?" You say, pulling a shirt on as you walk to the door.

"It's your neighbor!" Says a female voice on the other side of the door. "Ariana, remember?"

"Ah yeah, what's up?" You open the door, revealing Ariana standing naked in the open air. Your apartment door opens onto a walkway that also functions as a balcony. There's a rail and places for people to mingle on your floor.

"I've been listening to how you were helping Katiana for the last little while, and I heard you managed to finish the job." She says, unabashed. "Mind helping me the same way?"

You look Adriana over. She's quite into body modification, and so far this year she's decided to look a bit like a succubus. Pink skin, batlike wings, and a tail that ends in a heart. Aside from the abnormal, she has an hourglass figure with large, round tits and a great ass.
