Secretly slutty anal stretching

It's early morning and I quietly creep into the bathroom, careful not to wake anyone. I can't believe how horny I am - I just need to fill my tight little asshole! I look around the bathroom for something to play with and I find three bottles, each bigger than the next, and excitedly line them up, imagining how good it will feel to stretch my hole. I slowly work my asshole open, loving how the first bottle feels, but I need more! I use my fingers to stretch my butthole even more, and now I'm ready to take the bigger one. I fuck my ass with the water bottle until my poor little hole is a gaping wreck. It feels so good that I just can't hold anything back, so I pull the bottle out and pee all over. Next I stuff my whole fist inside, stretching myself even more. Time to try the biggest bottle Ive found, and it's so huge! I push and push, stretching my poor butthole to its limit. I don't quite get it in, but that only means I'll have to sneak away to play again soon!
