ESB: Lock the door and get inside the tank.
From Create Your Own Story
That tank isn't intended for two people, but you can fit in there with him. you tinker with the controls, lowering the ammount of bacta in the tank so that it won't overflow, double check that the doors are locked, and lock the security camera in the room so that its pointed away from the tank.
You reach into your jacket and pull out an aquata breather. It made no sense to bring it onto a world of Ice and snow, but you've always felt it was better to have it just in case you found yourself breaking through thin ice or something. You get undressed in a hurry. Despite trying to warm the base, everything outside medbay will give hypothermia or worse if you stay naked for any long period. You put the aquata breathe in your mouth, sling a weight belt on, and quickly get in the tank with Luke.
Even though you're not injured, the warmth of the bacta is warm and exhilirating. Your body is stimulated all over, particularly your nipples, which are now hard, and your pussy which is tingling. You understand now why Luke has such a monstrous hard-on. Speaking of whom, he's still not moving or awake, but that's fine. You easily remove the underwear from him, which slowly sinks to the bottom of the tank. You feel a little bad that he's trying to be a Jedi. He'll never again get the chance to fuck.
You wrap your arms and legs around him so that his big cock pokes your crotch.
There is no turning back now, where do you stick it?
