You'll know that the only food or drink you've had has come from sucking that special dildo on the wall for the nutrient paste it contains. What you don't know is that it lacks protean, but contains an addictive chemical instead. You have to keep sucking it or you'll go into a very nasty withdrawal. As for the protean, you'll be able to get that from eating cum.
You also don't seem to like your only toilet facilities being a grate in the floor. No toilet for my little sissy-slut. I take it you don't like being down here then slave? Well, whether you stay down here or not is your choice.
