<human>: Could you distill the essence of the text into 1-3 sentences?

I guess the title might sound kind of weird.

I've been working in a small office (dozen or so people) for 8 months now. My coworker Jon started around the same time as me and we started dating. The nature of our relationship is a bit unconventional so we make a point of keeping it secret.

In the past, Jon and I would go out for lunch on our own every day while everyone else ate inside. Our daily adventures made working a boring nine-to-five become fun- instead of bland "office-safe" conversations about kids and restaurants we could talk about sex, psychedelics, personal growth and basically any topic that's actually interesting.

One day a coworker asked me if she could join us, and I didn't want to be rude so I said, sure. We began to lunch with her a few times a week, with Jon and I occasionally quickly sneaking out so that we could still be ourselves and on our own once in a while.

However, recently a second coworker started asking me if she could come with Jon and I for lunch, as well as the other one, now on a daily basis. On Friday a third woman asked if she could come, making us five, in total.

I think if they knew that Jon and I were seeing each other they would give us more space, but probably they just think we're purely work friends.

I have to real reason to say "no" to these women but I really miss being able to escape work and be alone with Jon. He's in the same boat as me but he's not the one being asked about lunch.

Am I being ridiculous? Should I just accept that these women will always be lunching with us? Any kind of perspective is appreciated.
<bot>: Miss lunching alone with co-worker, people keep inviting themselves to our private lunches, how to say no or am I being ridiculous.
