So ive been wanting to tell someone but i guess this is as good as it gets. Ive become sexually obsessed with my mother in law. I live with with my wives parents, and it all started one night when she left her door wide open while she was naked. I only caught a glimpse of her bare naked body but it drove me mad. I know constantly find myself sexually fantasizing over her, wishing i could just pin her down and dominate her. I sometimes am left alone at the house while everyone is away at work or school when i have my days off and i regularly find myself raiding her dirty laundry sniffing her panties. I do this whenever i can i sonetimes get agitated when i dont. Recently things have escalated she likes to shower with the door a crack open and i catch mtself trting to catch even a tiny peek of her. In the mornings she leaves her coffe cup in random places and if i get the chance ill dip my dick and balls in it and its an orgasmic feeling knowing shes gonna down that cup of coffe. I catch myself licking up her lipstick stains from those cups if she leaves any. I dont know why this is driving me mad but i just had to share my story.
