I went to her, the pain might be linked to yr bum, its hard to tell as i can't touch it, she went i don't mind, do your job. Thats when i got in my p...ayful mood, she had her hands against the wall, her back and bum to me, leg spread. I grab her ass and started spreading the cheeks, i could tell she was turned on as she let a few moans, i ran my hands between her cheeks and very very slowly starting towards her pussy, i was taking a risk but it was worth it, she arch back and give me full. I was extremly horny now after teasing her and watching her pee all day so just a few mins after she climed in the shower I joined her, againg I was playfully told off saying couldnt she have a shwer in peace. I said I've got a lotha her to wash your back refering to my rock hard cock.She just laughed again and said I was so naughty what would she do to punish me. I said you could pee all over my cock if you want.She told me again to not to be so naughty. I got some shower gel on my hands and. I looked her over and then told her, "strip naked except for your heels and stand for inspection."She said, "Yes Mistress." and in a flash her clothes were on the floor and she was standing there naked."I told her she was the low bitch on the totem pole and she would be obedient to all the other girls and if we liked her by the time we all got to Maui then I'd probably let her stay for the entire trip?She said, " I promise I will be very obedient and do anything I'm told to do. I really want to. I cannot believe this scene – I am standing nude in front of my nude sister who sits on my bed and reaches to grab my penis. Without a moment's hesitation she opens her mouth and slides it over my glans and begins to suck. While I've imagined this scenario during many late nights, this is almost incomprehensible – I look down and see my penis in Sandy's mouth and feel the wonderful sensations of her tongue pulling gently and stirring extraordinary urges from some unfathomable depth.After.
