I was twenty and just starting my sophomore year at one of the local Universities. Her beauty took my breath away. She was a tall, lean blond with sky...blue eyes. At first glance, I guessed her height to be around 5’ 6," and she weighed maybe 120 to 125. The most noteworthy thing I noticed was her marvelous rack. There again, it was just a guess, but I was reasonably sure they were at least 36Cs.When I saw her that first day, I wanted to scoop her up in my arms and smother her with kisses.. "Please let me come... please fuck me... I will do anything you want, but please fuck your young mistress. I want to come so badly – Please Sir" she begged."I like obedient girls not begging bitches! Your pussy and your orgasms are mine and you will be allowed come only when you have proven that you can be an obedient young mistress. Now lay down over my knees so you can receive a good spanking for your misbehavior" I commanded my desperate young mistress.With fear in her eyes she slowly moved. Probably this is where she brought girls to have fun. I thought, as she unbuttoned my top. She opened up my top from behind. I let it slip it off my hands, as she finished unbuttoning and it hit the ground softly and now I was just in my panties. She ran her hands over my bare back of my neck to down below. Her hands rested on the edges of my panties shall I? She asked for permission, with her fingers inside the elastic band of my panties. I closed my eyes as my heart beat raced up with. After much discussion with Joyce and D, I agreed, and we set a time and a place which was public and relatively safe. So even if my sister was followed, they couldn't do anything. As an additional precaution D would come as well to make sure I was alright.I was very excited to be seeing my sister again, and it seemed like the day couldn't come soon enough.Finally the day came, I put extra effort into picking out my outfit intent on making a good impression with Gwen.After some cautionary words.
