So I closed the door to the dressing room and hastily removed my clothes I so excited to try it on. I pulled it up over my legs, the inside lining was...thick but its puffiness made it so it looked like a tight fit even though it was loose. I pulled it up to my waist and zipped it up. I was so turned on that my cock was leaking pre-cum. I zipped it all the way up to the top of my neck. I was so aroused I had to have it. It was $500 but that's why we have credit cards. I took it off, got back into. "I'm sorry, sir," she said. Then she paused and added, "You can spank me if you like."Now the formality of Rachel's first sentence threw me. We had always been on Christian name terms, and she had never called me "sir" before. As for her proposition, well wow! Where did it come from? As you can imagine, it caused my mouth to go dry, my face to flush, and my heart to pound fiercely against my ribcage. I gazed, hard and long, into my young secretary's eyes. My head was reeling and, when my reply. "FUCK YOU, SAM!" she screamed at him.Sam stopped like he'd been hit with a sledgehammer. His face went slack as he looked down at his little sister.Big tears rolled down Mia's cheeks. "What's happened to you, Sam?" she asked in frustration. "You're so angry all the time, and now you want to take it out on Brody when he didn't do anything to you."I was astonished. The change in the Mia's big brother was instantaneous and amazing. Gone was the rage-filled, muscle-bound, maiming machine, and in. My hand was stroking my clit hard now, and I couldn’t take anymore so I ran to my room and started playing with my clit. I got my vibrator out and made myself cum over and over. I turned over on my hands and knees and rubbed my clit..When suddenly Grace (my sister) walked in with no warning. “DAMN sis, what got you so hot?” I covered up quickly, but I was not quick enough. She laughed and sat on my bed. “I am guessing you saw me and Mike fucking huh?” I said, “How could you do that to mom?” .
