Couple fuck in empty doctors office

I got the shock of my life when I walked into the doctors office earlier this afternoon. I went in to tell him about his schedule for the day but instead of finding the good doctor at his desk, I discover this naked Spanish couple having sex. I was flabbergasted, speechless and instantly horny as this sexy looking couple tried to explain themselves. She was beautiful with an amazing body and I couldn't help staring at this handsome studs big, fat, long cock that was still standing to attention as he tried to explain what was going on. Now, as I saw it, the only decision I had to make was whether to report this saucy couple to the doctor or see if I could join in and turn this into a sexy threesome.
