I wondered what he was doing down there, but with the way that Jan was shaking and moaning I knew she was on the verge of a wild orgasm. My mate was t...oroughly enjoying himself. He touched Jan ever so gently, rubbing his fingers up lightly where her pussy was hiding behind her little knickers. Darren pulled her panties to the side and slid his finger deep inside her tight hole before gently finger fucking her.Slowly he moved his finger in and out, he was getting Jan all hot and juicy and ready. Robert stood and surveyed her flawless, alabaster coloured skin, before swishing the crop and slapping it into the palm of his hand. It stung, but served to let him know that he would need to be gentle, if he didn’t want to hurt her. He flicked the looped end, lightly striking her exposed bottom. She yelped dutifully and a small red mark showed the point of contact. He flicked at her again, hitting the other cheek. Again, she yelped and stiffened a little. “Master must punish me,” she. “So how did you get that bite mark on your boob?” “What bite mark? You must have done it…………………..no wait, it’s probably were my watch caught the skin when I was trying on some tops yesterday. I didn’t think anything of it at the time” She lifted her t-shirt and looked down at the mark. “Yeah, that’s what it is”.I didn’t push it, she was lying to me. Was she fucking someone? I wasn’t sure, but I’d leave it and follow up at a later stage. At that moment the door-bell rang and she took opportunity. Then she left and to my utter luck my other married sister came to have bath. I was ready for her. She slowly took off her cloths one by one and I was having a time of my life. Her Breast was more firm n bigger then my eldest sister. She was strong and firm and very sexy. I thought today was my day. I would come home soon and wait for them to take a bath/shower. Made sure had no appointment with anyone to spoil my peeping game. To my luck I saw my other two unmarried sister taking a bath, they.
