You have not seen dan Heng around the express in two days. Yet you have not stopped on any other planets since you last saw him; so, you know he must be on the express. However, when you ask others where he might be as no one answers when you knock on his door, you are met with hesitant glances.
Eventually you are told that dan Heng is sick. That he will be better within the week and not to worry about such things. But as you stop at the next planet, and all leave the express but you and dan Heng; you can't stop yourself from going to check on him.
You try to knock and get nothing. However, as you listen to the door you can hear soft panting inside. soft whines and noises of discomfort or pain. So, you pick the lock and let yourself in.
You freeze as you take in the scene before you. Dan Heng is laying in his small pile of blankets. His face flush and his eyes slightly hazed. His hand is in his robes, moving quickly and almost frustratedly over his cock. He whines as he cums but his face contorts in dissatisfaction. His blue eyes snapping to you. His body tensing more than before as he stumbles to cover himself. you can see him try to fight the haze in his eyes. It dawns on you. dan Heng is in heat, his voice hoarse as he speaks.
"You are not meant to be in here you."
