Ever since one of my friend fucked my father in-law, I've been obsessed with the idea of following her example. I already thought he was a hot daddy but the way she described him in bed, I felt like I was missing out on something.

More and more, I fantasised about getting taste of his cock, waiting for the perfect opportunity. If I was going to make a move on my father in-law, I had to be careful. Little did I know how overly-cautious I was being.

The opportunity came to me one morning while on vacation with my husband and his dad. We were on their family boat and my hubby, who tends to oversleep, left me alone with his daddy.

Daddy got tired of waiting on his son, complaining about wasting a beautiful day, and after having breakfast with me he suggested we take the dingy to the shore.

I agreed and we quickly made the short trip to a secluded patch of beach nearby. The boat looked small in the horizon, and I suddenly felt aware of what was happening.

We were completely alone, with little clothing and about 2 hours until my husband typically woke up. And even then, we would have a hard time seeing us from the boat.

So while he slept like a baby, his dad was rubbing lotion on my body. His hand "slipped" under my top and things got worse from there. I let him have his fun with my tits, and even got naked for him.

I kept thinking about what my friend told me. When I dropped to my knees to lower his pants, I finally confirmed what she said. He was huge and, as I found out later, he also knew how to use it. I took my time sucking him off until he was hard and wet. Then we laid down a small blanket on the sand to fuck on.

The sex was just like my friend hyped it up to be. He quickly took control, putting me on all fours facing the tiny boat in the distance. While he fucked me deep and hard under the morning sun, I kept picturing my poor hubby over there, looking around confused wondering where we went. Maybe if he looked out to the shore he could see us as two blurry figures having fun on the beach.

It had already been an hour or so since his dad and I left, about half an hour since we started fucking. We were hot, sweaty and covered in sand, but we kept going regardless until we were both satisfied. In the end, he even asked if he could give me a facial. I've always wanted my husband to treat me like that, and seeing as we had plenty of water to wash it off, I told him I'd love one.

After cooling off in the water, we started noticing some movement in the boat. We figured it was time we headed back to meet up with my husband. Totally clueless, we found him having brunch without a care in the world. The rest of the day went about as normal. We snorkelled, had drinks, got tanned... but in the back of my mind I kept thinking back on the morning wondering if I'd get another chance to fuck him.
