The beach - GM... and more?

I got invited to the beach by a friend of mine (16, I will call her Ruby, as all girls are gems)
Having no other plans for the day, I decided to go along.
So besides the usual beauties in bathing suits that populate public beaches which were nice to observe, I had Ruby and a friend of hers, whom I will call Emerald, cuddling with me to warm up after swimming, since they discovered I was warm! :D although this did not go over well with the boy who likes Ruby who was there.
She even outright ignored him a few times.
Anyway, I got to enjoy more cuddling, and Emerald being quite comfortable against me, didn't want to leave when it was time to do so, though eventually we did.
The 3 going one way, myself going home for a bit before going to Emerald's house, to which I'd been given directions, to meet up with both girls. (Ruby was spending the night there.) Anyway, we hung out in Emerald's back yard, mainly sitting and talking.

Eventually, with the temperature dropping, Ruby decided that I was better to sit on than just a chair. I couldn't disagree. Some time later Emerald, being cold, begged her way into switching places with Ruby. (two girls fighting over me! What more could I ask for?)
This arrangement stayed until I eventually left with the girls going inside... Although I did learn from Emerald, while Ruby was in the house, that apparently Ruby likes me.

This leaves me going home unsure of what to think. I must admit that I have been somewhat attracted to Ruby since the day we met a couple months ago, although I didn't intend to make anything of it, I think she may have picked up on my interest.
On a side note, by some bizarre coincidence, Ruby's mother started working at the same place I do about a month after I met Ruby.
Anyway. This was my day. Beautiful girls including one who is, apparently, attracted to me. Beyond the physical attraction I felt towards her, I'm not sure what I feel for her. I was simply thinking of her as a friend, as with all my other girls.
There would certainly be awkwardness at work if anything happened between Ruby and I. It couldn't fail to get known there at some point.
