Slipped in hard while tobogganing - outdoor fuck at -8 degrees

We walked through the forest for half an hour and I was so sure that the sledging hill was there. Unfortunately, we only found a very small one and my fuckbuddy was already super demotivated. That's when I came up with an idea of how to lift his spirits again. I pulled his trousers down, took his cock and just started to blow him. I didn't think the cock would be so hard at -8 degrees. That's why it didn't stop at the blowjob. There was a bit of a starting problem, but then it took off! He fucked me really hard, right on the path where everyone could see us. We didn't care. As further motivation, he squirted his whole load of cum in my face and mouth....
