It was last summer that I accompanied my Master to a party at his friends' house, where we arrived as the sun was setting, and after introducing me to his friends, they insisted on going to the outdoor area, where everything was almost ready to receive a group of about 30 friends, with several tables set up with drinks and trays of food, emphasizing making us approach a thick-trunked tree, where at the top, a wooden sign was nailed with the inscription "URINARIO", which, after reviewing it, I could observe that at the foot of the tree, two pieces of rope were laid out, after which, some ironic comments began from the three of them, alluding to the fact that they should get it ready before the guests started to arrive, to which my Master told me:

- Get completely naked! We're going to get the bathroom ready

- How? I asked

Hearing the laughter, almost instantly from the three of them, I received the sharp order

- Come on, bitch! Don't waste time and get undressed now.

I obeyed, with some reluctance, becoming naked after a few moments, under their attentive gaze

- Kneel down! he told me next

From the backpack, as I obeyed, he took out the wrist and ankle cuffs, adjusting them tightly to my wrists and ankles, and with me kneeling, he made me move backward, with his hands on my shoulders, until I found myself with a foot on each side of the base of the tree trunk and my back against it, where, in the presence of his friends, he tied me by the ankle cuffs to the back of the trunk, leaving me bound to the base, forcing my legs cruelly, until I was left with my ass stuck to the trunk, and then, with my arms back, one on each side of the trunk, he forced me to stick my back to the trunk, after securing the wrist cuffs in the same way to the back of the trunk, leaving me on my knees and tightly bound to the garden tree. But the culmination was when he took out a mouth gag from the backpack, which he placed in my mouth, forcing me to open my jaw completely, leaving me with my mouth totally open.

- Do you like it like this? my Master asked his friends

- Yes, it's great, one of them said, but the best thing will be to try it out to see if it swallows well

- Well, if it doesn't swallow, it doesn't matter, the important thing is that people enjoy the service

- I'm going to try it out, to see if it works

As he was alone with a pair, he opened his pants and took out a large, though somewhat flaccid, cock, and after placing his glans in front of my open mouth, he began to urinate abundantly, directing the stream to the back of my throat, which, being unable to swallow all the urine, spilled out of my mouth, falling down my chin to my chest, my thighs, and finally to the ground, where the ground became impregnated and absorbed the excess.

After shaking his cock and depositing his last drops in my open mouth, he commented
