Got caught

I am 14 years old and have been dating my crush for 2 and 1/2 months. Although he is 16 years old, he is incredibly sweet to me and genuinely cares about me. We don’t really do anything other than kiss. Last weekend his parents went to a work dinner and he had the house to himself. He asked me to come over so I told my mom that his parents were at the store and would be back soon. I walked into his house and sat on the couch. He asked me if I wanted to watch Netflix. We were laying on the couch when he started to kiss me. He then asked me if I wanted to have sex. I said yes. We had sex on his couch. His parents walked in and saw us. He hasn’t spoken to me in 4 days. How should I react? What should I do? Should I call him?
