Bound, punished and injected! Is that still allowed?

I'd only recently been educated a bit for my cheeky behaviour, which should have taught me a lesson, but it didn't last that long. I had a date with him again today and was supposed to make some preparations. For example, I was supposed to wait for him already bound and completely nude with the flat door open. I felt really queasy and hoped that no neighbour would come up the stairs. What would he think of me if he saw me with my legs spread and my hands cuffed? When the door suddenly opened completely, my heart dropped and I prayed inwardly that it was my date. I was lucky, but he didn't care about closing the door as quickly as possible. He wasn't exactly squeamish with me either and first fucked my neck properly as a greeting. As I hadn't quite prepared everything the way he wanted it, he wasn't happy with me and let me feel it. Sometimes I really had to grit my teeth, but I still provoked him a little extra. After all, his fuck is always the hottest in the end, especially when I resist him a little.
