Savita bhabhi in switzerland

Me (45M) have been recently watching my sons (17M) internet browsing history to see if he was studying for his NEET exam. While he was at school, I got on his computer, and he forgot to close computer properly so I opened it. I was greeted by a drawing of a little, short haired girl, in the style of a seemingly comic book, as his desktop wallpaper. As I slowly moved the mouse, a random spinning logo thing had opened, and then I was greeted by a chatting application named "Discord". As I was about to close the application, I heard a weird sound coming through his speakers. It seemed like a person was shouting with badly functional mic. As I opened the chat with him, I instantly saw an image of a brown haired girl, drawn in the style of his wallpaper, while holding rolling pin in one hand and some balloon like things on the other hand. Something was written on top of that wallapaper - 'Savita bhabi'. I frankly did not know why an image like this would be sent to my son, but without thinking anything of it, I closed the application. Now that the chatting app was closed, I moved the mouse to the browser icon, and I clicked. I forgot how to see the browsing history in a web browser, so I googled it. However, as I very slowly typed "how to see browser history chrome", it automatically recommended me another search option, which said "Savita bhabhi hot smoothie". I ignored this, as I seemingly thought nothing of it at first. After I remembered how to see the browser history, what I saw horrified me even more. Some of them read: "hot milf nearby", "Savita bhabhi adds cream to your coffee", "hot creampie". I do not know what a "Savita Bhabhi", "milf" or a "creampie" is, but I think it is a cooking term. But, I am not sure. What does any of these mean? Is my son aiming to become a chef? I never saw him cook anything in the kitchen. This is really bad. I don't want my son to be chief. What will say to my neighbors? Please help me to stop my son from becoming chief.
