This is Tommy and his invention, the HogSak, as photographed by Serious Male Bondage:

The HogSak is a unique and original device that combines the head trip of a straightjacket, the enclosure of a sleepsack and the intensity of a hogtie. It is a very intense bondage device and not for beginners. Once you are in it, there is sure to be a feeling of complete helplessness. Your arms are placed (one over the other), on your lower back (though some like them in front), and a waist belt cinches around you just under, pinning them in place and making you unable to lower them. Another strap passes from this same waist cinch, down around your ankles and forces the legs tightly up against the bottom, essentially immobilizing you in a perfect hogtie. This can be a very intense ride, with the convenient zip at crotch level being slightly lower than normal so that both the front and rear hot spots can be easily reached by your tormentor.
