"Hello! Anybody home? I have a delivery for this address!

This is weird, why is there nobody answering? The door is open, so I'll check out at the very least.

Oh, there is light coming from that room... and I think I hear someone. I hope whoever it is can confirm the delivery, I really need to ensure the client is satisfied after all"

As I promised (to myself at the very least) here it is the "futa client x female deliverer" scenario. Also kudos to @megaman9 for suggesting me the use of skimpy lingerie as I think it has enhanced the scene.
