Kinda weird..need advice about my sex-related problem..?

So me and my boyfriend are 16, I live with my mom and two sisters and he lives with his dad and 3 sisters. There are always people home when we chill either at my house at his. We've gotten away with having sex at his house for a little while--it's the only place we really can. But recently his sister decided to be a b**** and bust us so now we're not really going to be able to anymore. So..what now? We both still want to do it really bad we just have nowhere to do it...any suggestions? and if you're going to answer saying we're too young or lecture about the consequences of having sex I just don't want to hear it I've heard it all before. I want some real advice please.Kinda weird..need advice about my sex-related problem..?
