My mom and dad are staying but my wife keeps teasing me to have s.x?

I'm a 43yr old male. I'm married to a 24yr old woman, who is a stunner and fulfills me in everyway. However my parents are staying with us at the moment. Our house is small. My wifes a screamer and extremely into it. She basically wants it one or two times per night and that hasnt let up 2yrs into the marriage. It does get exhausting really. She has a body to die for huge real br.asts, and a great bum and i'm the luckiest man alive coz they are all mine and shes crazy for it. I told her im not comfortable having s.x with my parents staying with us as she will lose herself when we are doing it and be moaning and groaning when shes pleasured. Shes got real moody, its day 4. Last night she was cooking dinner on the stove. Her little skirt was really getting my motor running and i felt it was worn on purpose with high heels and stockings,suspenders the works. While my parents where out of the room, she was cooking on the stove and raised up her little skirt to show me she was wearing none. My parents walked in , i'm mortofied. How can i face them? And shes angry coz i'm not giving her any.6 more nights to go.
