I returned to undoing her dress, and soon had it off. As she lay on the bed in her black silk lingerie, I thought to myself how lucky I was. She read ...y mind and told me that for as long as I wanted it, she was mine to do with as I pleased.I soon had my shirt off as we took our time, enjoying the fact that for the first time there was no time limit on our lovemaking. I had my hand inside her knickers, teasing her pussy with my finger tips when there was a soft knock at the door.I went to it and. I could not be sure how many times my hand had met with her behind, but perhaps I had misjudged the opacity of her tights, experience told me that Lucy’s bottom should be glowing by now. I paused and asked Lucy to stand and turn away from me. Peeling her tights down to her lower thighs I inspected her bottom, her cheeks had coloured nicely and I gave her permission to rub herself. “My bottom really stings Sir” she announced as her hands were used to quell her discomfort. I reminded her that was. Our Masters returned and we got out of bed and went right over to them and knelt at their feet. I asked, "How can I please you Sir?"Mark looked over at Keith and said, "How about tying these two sluts up and allowing them to suck cock, two on one?" Sounds good to me" Keith said.The guys tied our hands behind our backs, then tied our tits tight. We were still on our knees and Mark pulled up a chair in front of us and told Keith, "You go on and be first bro."Keith took his belt off and stood in. 'He's eight years older than you'.Toby picked me up at 7:30 for school, fully dressed. I was just in a skirt and blouse, with no undies. I had a bra and panties in my book bag, though. When we got to school, we went to the undressing area, and there was quite the crowd. Toby remembered John and Joanie from last week, and stood behind me, slowly, tantalizingly unbuttoning my blouse; when he got all the buttons undone, he slowly opened it, revealing my tits to the crowd. He pulled the tails.
