I was born and raised in a small village outside Kiev after WW2. I was the oldest of five children; four sisters. We all lived in one room, my parents bed behind a curtain. For as long as I could remember, I would hear their bed squeak at night for three to five minutes, then my father sigh, and then silence. I had no clue as to what they were doing.
One day, my friend Marco who was two years older, and I were lying by the creek after swimming, and he told me they were having sex. I was so naive, I had no idea what he was talking about. He explained in great detail all the aspects of sex, (most of which were completely wrong), and when he told me my father sighed because it felt so good, I asked him what it felt like. He said it felt like when you rubbed yourself, only better. Again I had no idea what he was talking about. Marco pulled his shorts down, and rubbed himself to erection.
I was amazed at how large and thick he was, and how his foreskin slid up and down as he rubbed himself. He reached over, and pulled my shorts down, and rubbed me to erection. It felt so good, I didn't want him to stop. He rolled on top of me and began to grind himself against my penis and stomach. His weight on top of me felt very good, and I wrapped my arms around his broad back pulling him against me. I felt wetness on our stomachs and my penis, unaware of what pre-ejaculate was.
After just a few minutes, Marco began thrusting quickly against me, and I felt an unusual tingling build. I gasped as I orgasmed the first time, and seconds later I watched Marco throw his head back, moan, then intense wetness on my stomach. He went still, still pressed against me, breathing hard. When he rolled off me, I was covered in white semen from my navel to my chest. I ran my finger through it's stickiness, wondering what it was. I wanted to do it immediately again, but Marco said no. After an hour of begging him, we did it again, but this time Marco licked and kissed my neck, then my mouth.
We became lover's that summer, doing it by the river almost everyday. I would get hard at night when my parents bed began squeaking, and I would masturbate to the sound, thinking of Marco and me.
