<human>: Provide a brief overview of the text.

I've known my boyfriend for almost 3 years and we've been going out for about a month. Our friends have been trying to hook us up and we finally got together. I lost my virginity to him a couple weeks ago. Our relationship is open; we hug kiss and cuddle in public. My mom is very religious and has seen us cuddling. She got mad at me one time for holding hands with him in church and said it was inappropriate. Fast forward two weeks, my mom planned a trip to New York on short notice. I'm in highschool my sister now has a job and won't be able to come to New York. I tell my mom I don't wanna go, my sisters absence being half the reason. The other half is that I'm terrified of my moms boyfriend; he always stalks me and has 4 cameras up around outside of my house. So I don't tell my mom why I don't wanna go, just that I don't want to. So my mom assumes that I don't wanna go because I plan to bring my boyfriend to my house and have sex with him while they're gone, which is totally not the case. She doesn't know I had sex, she just suspects it. I planned on going to my dads house for the duration of the trip and didn't expect her to leave me alone at the house anyway. So when she gets home around 6pm she plans to talk to me and most likely chew me out about sex and God and I'm terrified. What do I say?
