We had discussed fantisies while lying in bed a few times S again mentioning how she wanted me to treat her like a slut and she would do everything i wanted without question. I loved the idea so we arranged for the house to be empty just us, my mind was going frantic about how far i took this. S dissappeared to the bed room and told me to wait till she shouted on me. Ten minutes of waiting then she shouted on me I entered the room to find her lying on the bed with the sexiest slutiest underware i have ever seen it was red satin and lace and her suspenders held up smooth shimmering tights, I smiled and smacked her hard on the arse she winced a little but smilled, I leant over and slowly pulled back the elastic of her pants and inserted a finger into her tiight little pussy, she was soaking wet and I could see the damp patch growing in her knickers." on your knees slut "I felt myself saying she obayed and i found myself staring at her sexy little arse i smacked it once more i took hold of the flimsy materil and ripped them from her arse, she turned round to protest so i smacked her again harder this time and she turned around red faced. I took my hard cock out my trousers and told her I didnt want to here a sound from her slowly i began pushing my cock into her i could see her back arching as I shoved my llength deep in side her and began to pump her cunt hard, once she made a groan to which I slapped her arse again she never made another sound but I could see by the glstening sweat on her shoulders she was enjoying her fucking, I feet myself about to come and orederd her to turn round and face me with her mouth open she turned round red faced and flushed and opened her mouth."open wider" she opened her mouth wide and I began pumping my my cock soon spunk shot from it I let it shoot into her mouth while I held her chin. I watched as my cum ran down her tongue and her throat, "shut your moth bitch" I wispered in her ear to which she did swalling hard. I told her to lie back and quickly removed my trousers and pants, then my t shirt. I crawled onto the bed and sqatted down on her face" want to feel yur tongue deep in my arse slut" to which I felt her tongue run slowly up and own my tight little hole,I felf it probing deeper and deeper inside, I was fucking loving it but I could not keep my balence I moved anto all fours and felt her behind me moving then I felt that hot little tongue of hers................ ok will finish later. my slut did so much more.
