Осталось на моей автоматической машине для нее - отказ в оргазме не до оргазма

I have a delightfully evil plan for my slave. I want him to be continuously and automatically edged while I’m away on my date..  So I’ve setup my vibrator on an interval times to auto-edge him until I return.. On just enough to keep him hard and frustrated, but never enough to actually cum.. Then off for a few seconds until repeating over, and over, and over again…  I bind him to my milking chair with his wrist cuffs strapped to the arm spreader, his chest strapped, and his ankles cuffed and bound.. I start teasing him with my hands while I surprise him with what I actually want to do with him (Poor slave thought he was getting strapped in for a milking video!) He had no idea denied and abandoned while connected to my edging contraption.. Hehe I leave him to go get changed for my date, come back to check on him- taunt him, and leave him again for an hour alone.. The cycle timer again and again tormenting him while I’m away..
