Reach out to them, the worst that can happen is they say no thank you. My wife has been recognized by three different guys she went to high school with and they each have fucked her a few times
I recognized a couple who worked for me. When I had the opportunity I told them I loved their pictures. Didn’t say anything else. Took them about an hour to realize what I was referring to. At first she got mad that I commented on her pictures even though I wasn’t explicit about what I liked. About an hour after that, I was invited over to their place after work.
An offer I took them up on many times over the years.
