My lover/master

I felt him entering me again and moaned loudly. This time he was thrusting even harder than last time, if that was even possible. I could feel myself coming close to the edge again.
"Master ... I need to cum... now"
"Not yet." Alex moaned.
I couldn't hold it on any longer and let go, screaming out his name. I felt Alex pull himself out and gulped, wondering what he would do. After a second or two, he pulled off my blindfold and untied me, still not looking me in the eyes or saying a word.
"I'm really sorry Master, I didn't mean to." I said and walked over to him.
"It's ok princess. Time for your first punishment. I'm going to spank you so hard you won't be able to walk for a week." Alex said smirking.
I followed Alex back to the bed where he pulled me across his lap. Then he put my hands behind my back and put on the handcuffs. I rolled my eyes, already knowing what was gonna happen.
