Bold! exploited by the horny neighbor!

It was a wonderful Sunday morning and I always take a shower in the morning. When I am completely relaxed in the shower, the doorbell rings. When I run to the door, of course, I forget half of it and had to go into the hallway as there was nobody in front of the door. Suddenly my apartment door slams! WTF! What do I do now? As I stand there, I notice that I'm not even wearing any panties. Completely at the mercy of me, I stand totally naked. But what happened next.
