parents found out

So my boyfriends parents found out we had sex and they talked to him about it last night. I want to have a conversation with them with my boyfriend. My boyfriend supports me, I just don't know how his parents opinion of me has changed, and I don't want to feel awkward at their house. And then today he don't tell his dad he was going on a bike ride with me, and then lied to him so idk I just need advice and positive reassurance please
