Utilizing a spreader bar in another way

The weather is too chilly for outdoor bondage, so I was brainstorming ways to use an old twin bed in the basement. I threaded a nylon cord around the headboard area, roughly at neck height when supine, looping it around the legs several times to stop it from sliding. I repeated this process at the foot of the bed for my ankles. Usually, I add a waist loop too, but skipping that was wise here since it would block me from freeing those bonds. My typical release setup (keys tied to a string inside frozen water within a plastic bottle) dangled upside down from the ceiling fan directly above where my head rested. I got naked and climbed onto the bed. A chain went around my ankles, pulled tight with a zip lock. Then I used another lock to connect this assembly—and myself—to the lower rope loop encircling the bed. Next came what some call crotch “rope,” though I favor chains more. I looped and locked the middle section of the chain at my waist, then brought the two ends up between my legs and fastened them back to that waist chain loop behind me. A clothes pin was attached to each nipple, held in place by a wide cinch belt. Here’s where it gets interesting: I have a wooden dowel with eye screws on both ends that serves as a leg spreader. One end locks into my waist chain. After securing my head to the upper rope loop (using a collar made of chain, naturally), I threaded a zip tie through the other eye screw and began tightening it slowly. Then I slid one wrist into a coil of rope—no chains this time since we’re talking 2-3 hours, which might be too much for metal—and pushed that end through the zip tie before inserting my second wrist and cinching the plastic with my teeth. The spreader bar is quite tormenting because it keeps me from touching myself to reach satisfaction (thankfully a DVD plays nearby). Although the rope holding my neck down is long enough to allow unlocking so I can move my head, it’s too long for me to lean over and remove those clothes pins from my nipples—a slightly greater agony. Eventually the keys fall into place, allowing me to undo the lock on my neck and reach down to release the ankle constraints. Why use zip ties? The sole sharp object within reach is a knife located three flights of stairs beneath the bed. Hopping around works too, but since the clothes pins remain attached, I started shuffling off.
