You stumble through the mansion, tripping over your feet as you search for a restroom. It's not exactly polite to barge into someone's house and use their facilities without asking, but this IS an emergency and you're sure the residence's master will understand. Your keep running through the halls until... EUREKA! A bathroom!
Well, a good enough one. By the time you're sitting on the can relieving yourself, you're disgusted by the level of cleanliness in this room. The tub and walls are coated in grime, the ceilings are a sickly brown from the... you don't even want to guess what's caked on to them, and the floor has so much stuff scattered on it that you can't see its surface. As soon as you've finished your business, you pull up your pants so you can get out of this rathole.
As your pants reach your waste, you feel something slide over your penis. Pulling them down, you see that a rocket red condom is now worn on your member's tip. At first you're curious as to how it lined up so perfectly as to slip right on your cock, but that's quickly pushed our of mind by the realisation that it came off the floor of this filthy bathroom and has probably already been used.
A groan of disgust leaves your lips as you try to pull off the condom. You pull and it stretches as you'd expect a condom to, but the lip of the condom that rests on your penis remains unmoved and the end never rips or tears, instead always returning to its original shape as soon as you let go.
Well, look at it this way: at least you won't have to worry about unsafe sex...
