Girl with big ass gets fucked in the mountains

I have done trips with my sister-in-law, likes the outdoors and likes hiking in the mountains. On the contrary, my girlfriend hates it. Then this morning I went alone with her. Really, I swear that my intention was only that of a walk in the mountains. But with her huge ass is able to get around me. He took me to a place far away from the main road and removed the pants. He made me see his ass, he touched and my cock became more hard. I could not continue to do nothing, then I removed the pants and me are fucked. I fucked her huge ass and I don’t regret anything.
