Occasionally I indulge in self-bondage and playing with clothespins etc, I've gathered some know-how about making a decent self-hogtie or chair-tie. Not that it measures up to the real thing of course, lying hogtied on the bed for thirty minutes is limited excitement if you have to imagine somebody using you, whipping your ass or treating you like a slut, and even if the ropework was tight enough you know it'll slowly begin to come apart rather soon.

I regularly turn on at the point when it's, like, for real: when bringing my tied hands into a noose that's tied to the rope around my knees, the tight pull is there, the arms tense and my body gets that twisted angle, I wriggle and think "Yeees, now you're the prisoner, the kidnap victim" but when you're playing by yourself, that's a passing feeling that, within ten minutes, you have to mentally recapture. In that sense, writing or just fantasizing, sometimes that's more effective.
