unexpected visitor

A knock on my door. Sleepy as I had almost fallen asleep, I rolled out of bed onto my week feet. I dragged myself over to the door. Too tired to look through the peephole, I opened a crack with the bolt still on, cursing whoever was disturbing myself at this late hour. But much to my pleasant surprise, a sexy doll-like young woman, probably in her early twenties, looked at me with a wide smile and big brown eyes. It was a bit chilly. I could feel the cool breeze brushing against my exposed neck, hands and feet, wearing only boxers under my blue house robe. She stood calmly there, seemingly not shivering, with only her sheer, short red nightie covering her petite body, exposing her vulnerable arms, shoulders and most of her legs. Though the hallway was dim, you could tell she wasn't wearing a bra. My eyes were wide open by now and when I was about to ask her why she rang my doorbell, she put a hand on my door and gently said, "Can I come in?" My natural answer was no but before the word came out of my mouth, my mouth swallowed and replaced it as if it had a brain of its own, "Yes, sure". I shut the door, unlocked it and open it wide with an inviting gesture, "Come on in".



Are there any mistakes?

Thanks in advance.
