18 [F] Persuading my much older, married PT to cum inside me (pics inside)

I started going to the gym 18 months ago, it was a bit daunting for me since everyone seemed to know exactly what they were doing and were much older than me. I was clueless. One of the PT’s noticed this and was super helpful, gave me a tour and showed me how everything worked.From then on we had a friendly relationship in the gym, we got to know each other fairly well and would often sit and chat for a while after I’d finished in the gym.

Two weeks ago he asked me if I’d like to look after his dog and his house for a couple of nights as he was going away for the weekend and his wife was in London with work for a week or so. I agreed eagerly as I adore dogs but mainly I saw it as an excuse to get to know him better and extend our relationship beyond just the gym. I’d always quite fancied Tom, he was tall, fit, and had that whole handsome older man thing going on. I wasn’t sure how old he was but I’d guessed at mid 30’s, maybe 34. I’ve fantasised about being with someone older than me A LOT, and especially someone married. I know that’s awful but the idea that I could fuck someones husband because I’m younger and more attractive gets me wet every time.
