In Bondage, less is more

Sometimes, simple imagery is the most powerful, sparking the imagination.
 

Black, rubbery gloves tell the victim that his predator is strong and dangerous 

- and harbours unconventional motivations.

 Blindfolded, arms pinned back, the captive follows his guard.
He is drawn along reluctantly, a noose-like halter tugging insistently at his neck,
and imagines terrible fates which lie ahead.
(Bound Gods) 

 Draven Torres tied up at Fetish Force

Multiple windings, imitating the seams of underwear,
emphasise to the victim his captive, helpless state
 and package up his male, erotic zones for the pleasure of his guard.
(Fetish Force)

Handsome, admired on the street, now he tastes captivity.

The casual, everyday clothing and absence of body embellishments 

create the impression of a man unspoiled, real and desirable,
and now he has been taken.

This clean, smooth, naked body used to sprawl in the comforting caress of soft sheets,
his luxuriant, coiffeured hair rested on downy pillows.
Now he is walled in by a cold, abrasive, rusty, metal grille.
The simplest of restraints suffice to detain him

and make for an economical feast for fetishists

Spencer Fox invaded at Bound Jocks
 
Forced to bend by corded windings tugging upwards on his arms.
During the game his jockstrap kept his manly organs safely pocketed
against the rough and tumble of his sport.
But now it leaves a tempting openness for the oily advances of other men. 
(Bound Jocks)

Jared at Dreamboy Bondage

Three-point bondage renders the captive totally defenceless,
preventing him from turning away from the punishing lash.
 The bolted-down, neck restraint, tightly encircling his throat,
allows no hope of escape and reminds him of his vulnerability

His captor has shaved his body
and dressed him in flimsy, see-through, lingerie shorts,
so that he may enjoy the gyrations of that part of the body
- when the punishment resumes.
