How some guys found out I'am a slut

So there is this guy i sometimes meet. He loves to use me like a little slut and i love to be used too. This night i went over to his house stripped a little for him and asked him if he wants to cum deep inside my ass. This would be the first time for me to have cum inside my ass cause he normaly cums into my mouth and i have so swallow his load. He said thats a great idea and i fall onto my knees and started to suck his cock. A little while later he pressed his cock deeper and deeper into my throat and i thought he would cum soon. So i stopped sucking his cock and turned around so he could fuck my ass. He pulled out my plug and pressed his cock inside my ass. He fucked me for quite a while and finaly came deep inside my ass. And then it happened. He pulled out his cock and put back my plug in. I was still on my knees having my spit all over my face from sucking his cock and some of his cum running down my leg. He took my leash and walked me out of his living room into the corridor while i was on all fours. I thought we would bring me into the bathroom so i can clean myself up. But then he opened the door of his flat and send me into the stairwell and closed the door behind me. I was on all fours covert in spit and filled with cum just wearing a bra a collar with the word 'cumslut' written on it some fishnet stockings my cage some heels and a buttplug. I needed some time to realise that any moment someone could come up or down the stairs and see me. I started to knock on his door. It took about 30 seconds and he opened it. I tried to get back in but he just gave me my hotpants and my top and said that this time i had to walk home like the slut i am and then he closed the door. I put on my hotpants and the top and thought about the best way home so noone can see me. There was the short way (about one mile) but i had to walk next to the main road and the long way (about 1.5 mile) where i had to walk trough a park. Since it was the middle of the night i took the long way hoping i am alone on my way through the park.
