Stepdad(55) and me(19)

I was home from college, brushing my teeth in the cramped single bathroom of my mother and stepdad's home. My step-dad, Tom, was in the shower. I finished up and started to leave when he pulled the shower curtain back and stepped out. My eyes darted over to see his big flaccid cock, making my mouth drop. I looked at him and instantly blushed. I went to leave the room and felt his strong grip on my arm. He pulled me back forcefully and pushed me down onto my knees. I looked up, stunned, at his piercing blue eyes. I knew what he needed.
