She wants to do it in public!

So while my sister was blowing me earlier she told me about one of her kinks. It was to be fucked in public like in a bush or something. I mean since we’ve started fucking we’ve tried literally everything like anal,creampies,69 and doggy and much more. I absolutely love fucking her and she loves fucking me but I don’t know if it’s too risky to fuck in public. She always lets me record so that when we’re to tired we masturbate to our videos together which is so good but recording and fucking in public may be to risky.
