My step-brother and his friends were all hanging out. I stepped downstairs and followed one of his friends to the bathroom. I walked in and shut the bathroom door to ask if his friend would like to join me in my room where I could finish him off. He agreed so I told him to follow me to my bed, we had to be quite, my step-brother couldn't find out. I told him I wanted to taste his cock but he couldn't tell anyone. I began to suck his big cock until he came all in my mouth, I didn't know he was going to cum that much!
