A stranger shared his girlfriends feet and nude pics

I have an instagram page for feet content. A guy recently texted me. We were talking about feet and he showed me his gfs feet. He wanted me to describe them. I have seen a lot of guys like this. Later her asked me if i wanted to suck those feet, as aleays i said yeah i am intrested. He and his gf called me, we had a long conversation. They agreed that they would do a video call for me as i am in uk now. They are asking 10k for 40mins call. I confused.
