Red-hot iron in the water

I remember a story, a real story of my youth when I was financialy not so wealthy.
I had a girlfriend about my age. She was sexualy very expiriend. Me, not so.
She had short haircut, smart blue eyes, and a mediteranean body type.
I haven't much money, so I use to take her in the almost desolated cottage of my parents, secretly, without their permission.
Was a house 16 meters from the sea, very isolated, north-oriented, and very cold during winter.
I still remember the brown moquette around the walls, and the wooden seilling.
We had visit it a lot of times, and never stay there for more than 2 hours. So no heating was available for so short time. The only heating source was our bodies. Even in shower we used cold water.
I remember one very cold day my limbs were really frozen.
Foreplay didn't make it any better. I tried discreetly not to touch her body with my hands, making overtime with my lips, but she caught me. That moment she reacted with something I couldn't predict. She look me in the eyes, took my hands and place them on her breast! The feeling was so intense, not far from red-hot iron, sinked in the cold water. Her warmth won my cold body.
The temperature of my whole body rise in seconds, and the rest of the time our bodies act with ecstasy, like we usually had.
Lots and lots of kissing, a conventional thing that always turn me on, and at the end getting deeper and deeper in her always warm and wet ocean.
Althought that day end like most of the happy tender days we had together, for me had a critical difference. Was a memory for the rest of my life.
