naughty photography

My friend was looking for some quick extra cash to get and she showed me an ad looking for young models for pornography. I have a boyfriend and I know he'd never want me to go into that industry, and at first I wasn't going to. But then my friend needed someone to go with her because she was nervous, and everything kind of got all caught up and when we went in, I got crumbled under the pressure and gave in to some "rough draft" photos in my bra and thong. I felt so uncomfortable that I knew I wasn't going to do it again, but I couldn't bare losing a relationship for a stupid and albeit wrong choice in less than one hour. So I lied to him when he asked me about my accompaniment with my friend that day. And I've been having the WORST dreams about my lying to him and it's making me feel so horrible and guilty I needed to see if this could make it better.
