Ultimate shoulder rides

As I mentioned in my last story (see: The Beginning) I started to love shoulderriding as I was a boy of 15 years.
The day after my girlfriend and I had our first victories in chicken fighting, we met her two friends at the pool again. After a few minutes of playing in the water the other two girls suggested a revanche. So we started chicken fighting again, but the two girls had no chance. They switched positions a few times and I think we had almost twenty rounds of chicken fighting.
After such a long time of chicken fighting we all needed a break. But only five minutes later the two girls had a new idea. What about a three person tower? Just to remember, my girlfriend and I weighted both 55kg, the other two girls 60kg and 62kg. So the bigger girl suggested to be on the bottom, my girlfriend should be on top and my part was the middle. But my girlfriend said she won't take part in a human tower and I don't wanted to sit on a girls shoulder. Because of the other boys at the pool, you know...
So the only possibility left was me at the bottom with the two bigger girls on top. I wasn't sure if it would be possible for me to lift a weight more than two times higher as my own. But let's just try it.
At the first attempt I thought I would die under all that weight on my back and shoulders. But the second attempt was more successfull. I was nearly struggling but I managed to hold them up for nearly 10 seconds.
After that I was a little hero for the three girls. And my girlfriend was very proud, not knowing how my back hurts at that moment.
But since that day my favourite kind of shoulderriding was always a three high tower.
