Sexual frustrated

Yes I am very sexual frustrated. Me and my bf work schedule is completely different when he's going into I'll be getting off. On top of us not living with each other and living with our parents and of course my sister and niece shares a room with me. Car sex is a option but it can be a bit uncomfortable sometimes and I don't have a toy. Tonight he's over my house hanging out but everyone is home and with so many cars driving up and down the street and other stuff idk if I'll be able to get dick tonight. I need dick and I need it now. What would you do in my situation?
