My Cum Mixed Coffee for My Father-in-law as a Result of Sex with My Stepmother

That morning I saw my stepmother in the kitchen making coffee for my father-in-law. I approached him and we chatted for a while and I offered him something he never got. Yes, I offered to have passionate sex with her because I knew my stepmother never got satisfaction from my father-in-law, which I peeked at every night, my stepmother often masturbated next to my father-in-law. And my stepmother also without resisting in the slightest, we passionately in the kitchen until my sperm cropped in my stepmother's mouth and then she spit my sperm into the warm coffee that she deliberately made for my father-in-law
