ADVISE NEEDED: places to have sex as a teen?

recently me and one of my guy friends (both 16) have become fwb, and our sexual tension is so strong that when we make out and grind I’m so turned on that it physically hurts to not have him inside me. neither of us are virgins- we just have the issue of finding somewhere we can fuck! in my house my parents set up cameras throughout (not in bedroom or bathroom) so i can’t just sneak him in when they aren’t there, and he has two much younger siblings who are almost always home so his house isn’t a much better option :/ where can we have sex if we can’t in our beds or in a car?? the only places i can think of are way too risky to get caught or are straight up uncomfortable. i rlly need suggestions so any would be appreciated 🤷‍♀️
