"Don't move".
I gave a small gasp as I woke in the dark, not understanding for the moment who was standing there. I cursed myself again for my bad habit of leaving doors unlocked at night, well for that matter, during the day when I was at work.
"Get on all fours".
The commands came, as if he knew I wouldn't resist. I slid up, my belly off the bed and presented myself to him.
"Stay there and don't move again till I tell you."
I felt his hand caress my back and I felt more naked and exposed then I actually was. I could hear his hand working his cock, and I felt a thrill go through me. His hand was rubbing my ass cheeks but I wasn't prepared for the sudden slap.
I jerked in response, but backed again into his touch. He moved closer and then I felt the soft thud of his cock slapping my ass, the sound turning me on. I wanted to play with my clit but I wasn't sure if I should.
"Lie back down, and spread your ass cheeks for me".
