Milking, frenulum teasing and postcum punishment on immobilised twink

Completely immobiled twink guy wrapped in black stretch foil. He moans from pleasure, every time my hand, mouth or magic massager touches his hard uncut dick. I was keeping him on the edge by wanking, sucking him and teasing his sensitive frenulum. His body was wriggling more and more and finally I've let him spread out his cumshot but It wasn't the end. I've learned how to distress him a bit after the cum and It was the most intense and sinister at the same time. He couldn't refuse.
