I was tied to a chair, hands behind me and legs secured tightly to the chair legs. Completely nude with a vibrator in my pussy and another one in my ass. Nipple clamps screwed down as tight as he could get them with a string threaded around the clamp on each nipple. Those strings go a few feet across the room to the bed where the other end of the strings are wrapped around 2 vibrators laying on the bed.
Further across the room he is sitting there smoking a cigarette and has a remote control in one hand and a stop watch in another hand. Every 90 seconds his hand moves slightly to click a button on the remote and all 4 of those vibs simultaneously start vibrating on high.
My screams of pleasure from my pussy and ass mix with my screams of pain from the vibrators pulling and jiggling on those super tight nipple clamps.
