Before long I realized that my c**k was getting hard. I slid my hand down across my growing member and could feel the smooth satin material. Slowly I rubbed it through the thin fabric. Finally, I slid them down a ways and started to jerk off. Just as I was about to blow my rocks the door opened, and Karen stuck her head in. “Oh did I disturb you?” she asked as I scrambled to cover up. “How’d you…?” “How’d I get in? The same way you did in my room this morning. A piece of tape works just fine, doesn’t it?” “So how’s my little sissy slut doing? A little horny I see. After all the humiliating things I did to you today, you’re still that excited?” “I… ah…” “You were jerking off, weren’t you?” I didn’t answer her. Quickly she grabbed the covers and pulled them away totally exposing me.
