Here he had been put into an armless bondage body, the legs strapped down cross-legged with rubber belts, cock exposed. The mask he is wearing is completely closed, apart from the mouth.
Somebody unknown puts a ring gag into his mouth and seals this remaining hole with cling wrap. Unfortunately it's not really air-tight, so other measures have to be taken.
Watch him struggling while his mouth is being fucked by a large inflatable dildo and being allowed to cum by his own hand… :)

Believe us, it's hard to make noises with such a thing deep in the throat (not to speak about getting fresh air).
