I had something similar happen back when I had my photo studio in the last 90s. A 30-ish woman scheduled a photo shoot with her boyfriend some some romantic (rated R) photos. Topless, kissing each other, etc. Erotic, but not porn. They were obviously turned on by the photo session (and each other!), and I can only imagine the activities they indulged in once they left.
The following week I ran into her at Kroger. She was wearing a wedding ring, and was accompanied by two kids and a man I was pretty sure was her husband(based on body language, etc.) The husband was NOT the man who came to the photo session with her.
I could see some panic in her eyes when she recognized me... I didn't let on anything of course.
