This smaller version of our larger "Hour Glass' has only enough sand to last 4 minutes. Used in a scene during a very intense moment, 4 minutes can seems like a very long time. 

The electricity is turned up to 99 on the Erotek 312 box.

The 20 lbs. of weight hanging from his balls stays there until the sand runs out.

You keep jerking him off, after he's cum, for another 4 minutes.

Maybe 'Breath Control'  shouldn't be in this group.

We're sure you can come up with a bunch of more nasty ideas for this old fashioned timer, besides it just looking really cool on your bookshelf.  I guess you could also use it in the kitchen for something or another. 

I've alway thought an hour glass was a pretty cool device. Pretty 'low tech' when it come to keeping time... no diodes or flashing numbers.   It's also 'very' easy to reset when the time is over. This piece can take us back to 'when times were simpler'. A classy gift for your Sir, Top or Master...knowing full well he may use it with you someday. A quality piece that is 6" tall, dark brown walnut wood top and base with glass bulbs.
