I discovered that this buxom lady, Fay, whom I have known for a long time now loves to be fucked in bondage and has fantasies about captive group sex. I also discoverd that when she is bound she has a habit of tugging her legs a lot when being penetrated (I think because she is thinking about sex as a captive) - so I devised this position. It means the more she tries to use her legs the more she puts pressure on her arms - and if she tries to use her arms it pulls her legs further apart. On occasins I have also inserted a dildo into her anus which drives her wild as her other fantasy is being double fucked.
