How I [F] seduced my dad’s friend [M]

At least I like to think that it was me who seduced him.
Quick disclaimer: 1) English is not my first language, please excuse my lame punctuation; 2) I had already turned 18 when the story happened.

A few months ago my family, dad’s friend (Nick, unmarried) and a female friend of his (Alexis) (who is in a relationship, not with him) went together on a vacation. That was actually the first time I met Nick and I immediately felt attracted to him, he’s exactly my dad’s age but I didn’t know this at the time and honestly age was the last thing I was thinking about. I absolutely loved his vibe, body and manners.
Over the next few days I was wearing just a sarong (kind of like a big shawl) and occasionally swimwear underneath but only when we were on the beach. That’s how I usually dress when I’m on holiday. My back is naked and one could easily see that I have no underwear. So yeah, the sarong basically makes my curves really stand out and I noticed Nick eyeing me on more than a few occasions. I was very happy about that and it gave me hope that maybe something could happen between us, although I was with my family so even if it did, it wouldn’t be while we were on this particular vacation. Every night I thought of the things I want to do to him and even dreamed about some of them actually happening. You could say that I was low-key provoking him all the time.
