How I was made a toilet whore

After my divorce, I was in a relationship with a couple of dominants for a year and a half. Once we met in a cafe in a shopping center with a 26-screen movie theater. They sent me to the toilet with 12 stalls. I went into one of them, undressed completely, even took off my shoes and socks, put everything in a backpack and a few minutes later the Master came, I opened the door for him and he took my closes, leaving only my phone and headphones. I spent more than two hours in the stall of the shit-stained toilet, naked and defenseless. I was cleaning, directed by my Masters via video chat. Without going into details about how I cleaned, I will say that I was desperate. I was afraid that someone from the neighboring stalls would find out what I was doing. When the Master returned, he gave me a pen and I wrote on the door under his dictation ""Toilet slave without any limits"" and below my phone number. After that, the Master returned my closes to me and waited until I went out to check the quality of the inscription left. We returned to the cafe and they gave me something to eat. I was shaking with fear that someone would call me. After about 40 minutes they let me go and I ran to the toilet to get rid of this inscription.
