i always wanted to knock a girl out with a blow dart, then have her wake up naked in a room. the room will run out of air in 20 minutes, and the door is locked. the only way to unlock it is with a cum sample, forcing her to ejaculate. as soon as she unlocks the door, a trigger mechanism immediately shoots a dart at her thigh, knocking her out. the process is repeated, and she i forced to play along or else she would die from lack of oxygen.
