So in the end mum and I stayed and dad went off to his new life in Thailand.One Sunday afternoon mum and I went to the airport to see dad off to Thail...nd. At the airport mum hugged dad very tightly “Please don't leave us.” “It's an opportunity that I have to seize. Besides, I'll be coming back often to see you both.” Mum was crying, dad gave her a sloppy kiss, then pulled away from her and disappeared into passport control. I put my arms around mum and tried to comfort her, but she was still. The dom went over to the night stand and picked out some things and went back to the spread legs of her sub. She fastened a cuff to each of her ankles and wrists. Then she grabbed hold of her left ankle and raised it up till she could fasten it to the cuff on her left wrist. She did the same to the right ankle and wrist. This spread her pussy lips open even more. Oh what a glorious sight. I wanted so much to be between her legs.The dom got down on her knees in front of the sub and blocked my. Dance like this, mama? You mean, like you do sometimes when you get high and playing around.” “Yes, baby,” she said coming closer and turning the joint in her hand so Darla could have a puff.“Damn Mama, thanks.”“You do it anyway, so why not with me; right? I think you do lots I don’t know about, Darla.”“What do you mean?” Darla asked exhaling slowly.“I think you know, like I did at your age, that you can get what you want with that pretty little thing between your legs. Just dance, baby.. . like fornicating facing away from her partner, my personal favourite position.It was my hypothesis that mother got hot when she is forced to do things that a lady simply would not do. Things that she had always denied herself and needed me, her son, to force upon her. Things that would horrify the church members if they knew.I was still far away from an orgasm and I began to wonder if dad would finally catch his wife and son in a very compromising position. This needed something more drastic.
