Mark and I were made for each other, that's for sure and I knew I was pleasing him by being a little slut this weekend.I was still on my knees in fron...t of Robert and I decided I better keep my eyes down and quit side glancing Mark. Robert held my leash firmly. I started feeling shaky, helpless, and I liked it. I slowly looked up into his eyes, and as we stared, I felt something pass between us. Some men just have a natural dominant power that emanates from them and Robert definitely was a born. ”“Say it.”“Oh, oh, oh…”“Say it!”“Penguin.” And then it all stopped. The cock I suddenly loved, slipped out, the orgasm I needed slipped away. Please no. Bring it back.He rubbed my ass with one hand and massaged my shoulder with the other. “That’s your safe word.” I whimpered. Why wouldn’t he just finish.“Once you say your safe word everything stops. The reason for this is that I’m going to do things to you that will make you say ‘no’ or ‘stop’ but you won’t mean that.” He rubbed my spine with. It usually meant that I would sit next to her on the sofa, slip my panties to one side and gently wank myself.Occasionally though, she would get excited, slip one hand under her nightie and start to rub herself, making me watch whilst she had an ever slower, more sensual wank. One of the really good things about this was that, technically, my sister was my first sexual partner. She would gently wank me, watch me cum over her hand, over my stockings, over Mother’s shoes, even over her. When I realized I was staring at her feet, I felt deeply ashamed, and seemed that all the blood rushed to my face."Sorry, Mali. Good morning!"And I rapidly added "I am still very sleepy, and just forgot about you being here. I'll go and get dressed more properly." Please, don't! This is your house, please act like it and do whatever you want!" She said the words so fast, and her tone was so sincere, that I complied, and entered the kitchen as I was.There was a huge difference between this.
