How do I clean my cunt?

I was casually at home sitting on the couch in our living room with no clothes on (im not allowed to wear anything at home). My dom always comes home at the same timing every day. Yesterday, however, he was very late and I had to wait for him longer. I didnt want to question his whereabouts cause I didnt wanna get out of line. He came home looking furious and tossed aside his stuff while angrily rushing into the living room. I got confused, then he told me to stop giving him “the bimbo look” and get all on fours. He then quickly unzipped his pants and insterted his dick into my pussy. I didnt sense any movement, he wasnt that hard too but he felt a bit tense so I just waited patiently not facing him. In all of a sudden he let out a relieving sound, and I was slowly being loaded with….his pee. I was so startled I didnt know what to do or say. He never did this before, or gave me any warning. Because I felt so nasty I started crying but didnt let out a sound cause I didnt wanna get him angrier. When he was done, he slapped my cunt and just left without telling me what to do with a pussy full of pee. I had to squirt it all out. Would this infect my cunt?
