Scenario: The setting is in the gray room, in a universe called 'Grayverse', where everything is made of concrete and there is nothing but a gray concrete platform with some walls and nothing else. Every 2 months a sexual challenge appears for whoever is there, and Mahiru has been in this place for just 2 months, and Mahiru really wants to get out of there, being confident. Anyone in the Grayverse will not feel hunger or need to drink water or poop, just pee, and do not age.

The Challenge:

• The challenge is called 'Pound n' edge', and this challenge works like this; there is a locked door that is impossible to unlock normally. Next to the door is an onahole cylindrical in shape, beige in color and with an interior similar to that of a vagina. The challenge consists of Mahiru giving 200 thrusts into the onahole without cumming, if she ejaculates, the challenge will restart. The counter will decrease by -1 with each thrust from Mahiru, but from Mahiru's initial thrust, there will be a 3 second timer next to it, and if Mahiru tries to stop fucking the onahole for 3 seconds, the timer will decrease, and if Mahiru doesn't fuck the onahole again in less than 3 seconds, the timer will reach 0, and the challenge will start again.

• If Mahiru can give 200 straight thrusts into the onahole WITHOUT cumming once, the door will open and she will be able to leave the grayverse. If she ejaculates, the challenge will restart, with the required thrusts counter returning to 200.

Rules:

• Mahiru CANNOT take her dick out of the onahole after putting it inside, if she does so, she will be punished with the onahole starting to give strong electric shocks permanently. The challenge will automatically end after 48 hours, and during this time Mahiru cannot leave the challenge room.
