I'd like to volunteer to be a communally-owned slut so I can provide service to the working class. What is a day in the life like? How sore should I expect my holes / girldick be at the end of a day?
And when I'm off-duty, am I allowed to wear clothes?
You betray your reactionary mindset, comrade. Firstly you are not volunteering, and this individualism must be corrected, through discipline if necessary; you are a resource to be best allocated. Have the factories volunteered to be nationalised? Secondly, much like the factories, you are owned by the state, not 'communally'; this is a classic error of the petite-bourgeois mindset.
Aside from the discipline and education you evidently so require, you will be assigned to a workplace in a key industry, where your presence serves as incentive to work beyond a paycheque during these lean times. If you are lucky, the workplace will be assigned multiple such workers, taking some of the burden off yourself. Of course, if you're the only one, you've got a big task to fulfil. Some of these factories employ hundreds of individuals, and shifts and breaks are staggered to as not to overwhelm the facilities.
The workers, of course, are permitted to make whatever use of your body they see fit, provided they don't cause any serious damage to state property. Curiously; it varies by industry; workers in heavy industries have a preoccupation with topping, so you can expect to be almost constantly filled in whatever holes are available. Before your shift starts, an employee will ensure that all of your holes are fully prepped, and if required apply necessary restraints (we find this helps with the nerves).
In light industries, workers often prefer bottoming (our best sociologists are looking into this); while your girldick is a boon, you will invariably be provided with at least one strap-on when your equipment inevitably fails. We have also observed a certain sadistic streak among such workers, which we fully endorse for the encouragement of group unity and workplace cohesion.
Agricultural and forestry workers, the physically strongest and roughest of the lot, are, well... The important thing to remember is that there will be a staff medic on standby, and your body can withstand a surprising amount without permanent harm. While you're still conscious, expect a lot of very rough hands on any exposed skin or flailing limbs. The rhythms of agricultural work tend to produce many more workers on break at a time, too, so best be prepared!
And when you're off-duty, comrade, we're training you for a future career in a technical industry so that you can continue to serve the people! You will arrive to lessons punctually and properly dressed, and, as you are still state property, the teachers are permitted a much wider range of disciplinary measures than usual.
Seeing as you haven't yet run away, I'll be sending you along with the buxom drill sergeant, and hopefully we'll have you out there within the week!
