You look for another solution

You step back from Glissara, your mind already racing through geometric permutations. "I'll find another way," you mutter, more to yourself than to her.

Your eyes trace the web of light beams crisscrossing the chamber. There—a mirror mounted higher on the wall, currently catching nothing. If you angle it to catch the prism's rotation at a different point in its cycle, you could split the blue wavelength before it reaches Glissara's position. The solution crystallizes in your mind: a more complex path, bouncing the beam through three additional reflections, but viable.

You move to a mirror on the opposite wall, your bare feet leaving wet prints on the increasingly slick floor. Sweat pours down your exposed torso now, dripping from your nipples and running in rivulets along the defined lines of your abdomen. The heat has become almost suffocating, and with it comes an unmistakable arousal that makes your cock strain visibly against your leather pants.

"You are very determined," Glissara observes, her translucent form rippling as she watches you work. "Most give up and let Glissara touch. You are interesting."

You don't respond, focusing entirely on the calculations. Angle this mirror fifteen degrees clockwise. No, seventeen. You adjust the bronze mechanism with trembling fingers—not from fear, but from the building need in your body. Every breath feels heavy, every movement sends friction through your sensitized skin.

Minutes crawl past as you work. The prism's rotation means you must time your adjustments precisely, watching the cycle repeat three times before you confirm the correct angles. Your glasses slide down your sweat-slicked nose repeatedly, forcing you to push them up with the back of your hand to avoid leaving fingerprints on the lenses.

"You are getting very warm," Glissara comments, sliding closer to observe. "Your skin is so shiny now. Does it feel good?"

"It feels hot," you manage, adjusting another mirror. The blue wavelength finally splits where you need it, arcing over Glissara's position entirely. "Almost there."

Your arousal has become painful, your cock fully hard and throbbing against the confining leather. Pre-cum dampens the fabric. Your nipples ache with sensitivity, and you're acutely aware of how every drop of sweat trailing down your bare chest feels like a caress. The dungeon's magic is working on you, building pressure that demands release.

But your mind remains sharp enough to complete the final adjustments. The blue beam joins your collected wavelengths, and suddenly all five colors converge. They blend, merge, and birth a perfect shaft of pure white light that strikes the circular depression above the bronze door.

A deep metallic clunk reverberates through the chamber. The door swings open slowly, revealing darkness beyond.

"Oh!" Glissara burbles with what sounds like genuine admiration. "You solved it without Glissara's help. You are very smart. Most cannot do that while Glissara is here."

The door stands open, your path forward clear. But your body burns with need, your arousal almost overwhelming. The relief of solving the puzzle wars with the physical discomfort of your intensely aroused state.
