Beach day

I find myself on the beach, lying on the sand and soaking up the sun, quite far from the water's edge and out of sight of others.

I'm not allowed to use a towel; my master hasn't given me permission to use one, saying I don't deserve it.

After a couple of hours in the sun, I feel the need to urinate, so I ask for permission to go to the water to do so. He tells me to go to the water to wash off all the sand stuck to my body, but not to urinate.

To make sure I comply, he tells me I have to take off my swimsuit and that I can only go in up to my knees. I'm left thinking about what other people will think when they see the cage I'm wearing and the plug that's visible when I bend down to get water and wash off the sand.

In the end, I decide to do it and take off my swimsuit; my heart is racing, and now everyone will be able to see me as I am. "You hesitated," he says. He strokes my head with one hand and puts a clamp on my right nipple with the other, then puts another on my left. "Now you're ready to wash off the sand; don't take long, I have a surprise" and he squeezes my nipples so hard that a cry of pleasure escapes me.

I turn around and head towards the water's edge, looking left and right; there's no one nearby, and I feel a bit of relief as my heart calms down. Once I'm clean, I get out of the water and walk back to where my master is. Even though I have the cage on, everything is throbbing. This whole situation is new for me, all the feelings and thoughts are new... and I like them!

When I reach my master, I see that he's not wearing his swimsuit, and he tells me to get on all fours; I obey. He removes the plug and puts it in my mouth. Without knowing what's happening, he tells me to relax, and I calm down, and then he inserts his member into my ass. I couldn't be happier!

When I realize what's happening, I don't feel his thrusts against me, but instead, I feel something hot inside me taking up more space. He crouches down to whisper, "This is your purpose in life; you only serve to satisfy my desires, and now I desire you to be my private toilet. I've been holding it in all day, and from now on, whenever I feel like urinating, you'll go to the bathroom for me. For now, we'll use your ass; over time, you'll learn other ways to serve my hygiene."

While my master is emptying himself, my mind doesn't stop racing; I'm happy! When he finishes, he tells me I can now go to the water to urinate. He removes the plug from my mouth and puts it away. As I look up, I see that there are now people walking in the area I need to pass through, "I think they've seen me!"

I don't think twice and head to the water, but as I start walking, my master tells me, "Remember, the water can't go above your knees!" I tell him yes, look down, and smile as I head to the water.

When I reach the water, I turn around so my master can see me and start urinating. As I'm letting it all out,...
