Hot Roommate Cam

My roommate is astoundingly hot. Her room is being repaired (the ceiling fell in), and, at her request, I’m letting her and her boyfriend sleep in my room while I take the couch. I’ve been able to contain my attraction just fine up to now, but the minute she entered my space I had this feeling that all bets are off. I’m considering spying on her with a hidden surveillance cam. If I had video of this girl naked, let alone being fucked, I could happily beat off to the footage for the rest of my life. Obviously it’s a breach of trust, and I’m a shitty roommate for considering it. I have a few concerns. Is this normal? Assuming that there’s no way she could find out and that I kept the video to myself and myself only, would it be so wrong? What is her reasonable expectation...
