Sam broke turned left at the fork and kept running. He found himself sprinting down an identical corridor — long, white walls and tile flooring — with no end in sight.

Just as he started to consider whether or not to stop and get his bearings, the unthinkable happening. The floor gave way beneath his feet, dropping him down into a pitch-black pit below.

It was a long way down, but after a few second he slammed face-first against the pit's surprisingly plush, springy bottom. He bounced hard when he hit the ground, but wasn't hurt at all. After taking a moment to reconcile the fact that he had fallen through a literal trap door, he started to look... Well, to feel around.

The room was still pitch black and he didn't want to fall again, so he very gingerly patted the ground around him. It was soft and cool. It almost felt like a... mattress? He continued to feel around, grasping at the dark for an edge, a wall, furniture — anything that could help him get his bearings.

He knew this had to be part of the test, but he couldn't help but feel nervous. How long would they keep him down here? What if they never let him out? Or turned on a light, for fuck's sake!?

Overcome with panic, he told himself that he should lay down on the bed-floor and wait for someone to come give him instructions. It was the only thing he could really do safely.

Sitting still calmed him down some, but it gave his chemically induced hard-on the chance to take over his thoughts. He wanted to cum so bad. To wrap his hands around his cock and relieve the seemingly overwhelming pressure building in his balls.
