When a teenager this girl came on to me while swimming

I remember when I was a teenager this girl asked me to help her swimming, but wanted me to cup my hands over her breasts in her bathing suit. It was a daring thing to do as both our families were also swimming there. Needless to say this was a good sensation. Around the same time I happened to be in an inflatable boat and invited her in. When we were paddling away from the crowds as we were facing each other I decided to use my toes to move her bathing suit bottom to expose her pussy and to use my big toes to stimulate her. She loved it and did not seem to mind. Now years later I wonder if that was normal.
