Go to the coma ward

You hit the up button and chuckle to yourself as you wait for the elevator. Like you were going to dress up as a doctor and sneak into a hospital just to visit some random skank in the feeding room. You fondle your still partially aroused cock as the elevator doors open to reveal a pretty redheaded face only a foot or so away. See? Bitches are easy and you're on a mission.

She looks up at you like she is trying to recognize you from bent over in front of another man. Without skipping a beat you step forward and slap your cock into the throat of... Is this the same woman from earlier with the clipboard? Well whatever, she clearly has a purpose in life: To keep your cock warm. You look up and around to avoid eye contact so she won't recognize you and nod respectfully to the man as the elevator doors close. You fuck her throat as the elevator begins its ascent.

By the time you and the man behind her have worked out a good rhythm the doors behind you open to your floor. You thrust extra hard one last time, trying to **** a gag, then withdraw your cock and round the corner of the elevator out of sight in the same move. You hear a complaint about a dose from behind you and resist the urge to yell about your sister being in a coma.

Now where is she? As you walk along you see a small orgy on the floor of the hallway. Two men, on either side of a donation girl, and on the very bottom... is that?

"Hey doc! Bring that over here!" You hear your mother calling to your penis from underneath a plump donation girl, between another man's legs. The man takes this cue for himself and pulls out of the donation girl's ass to holster his filthy cock in your mother's mouth; his balls falling over her eyes before she manages to see through your costume.

You quickly grab a nearby surgical mask and pull it over your head to obscure your face. Hadn't really thought this whole thing through. You look at the room they are in front of, clearly labeled "Susie Dover", your sister, and see nothing but an empty bed inside. Shit.

Before you can try to decide your next move a yell comes from a nurse rapidly approaching you from down the hallway.

"All scrubbed up for surgery Doctor...." She looks like she wants to recognize you but is failing. She sneaks a peek at your name tag as she gets closer. "Doctor Gagar?" She says confidently. If this seems odd to her she doesn't show it.

She begins to drag you away from your mother's gangbang as the two men walk around, exchanging sides on the pile of women. Probably just as well. Can't have her blowing your cover and clearly your sister isn't here now. Though this could be a good chance to take out some unchecked aggression on your mother anonymously. Hmm...
