First time masturbating in public F20

I've been under a lot of pressure lately and I almost forgot about masturbation. The night before yesterday, I was browsing pornhub and suddenly had the idea of masturbating outdoors. I tried to tell this idea to my friend, but he had tried it before. He encouraged me and said that I would definitely love this feeling. So I waited until 11 o'clock last night, and I went to the park near my home with my masturbator. Because of extreme excitement, my dick was already hard. I put my dick in the masturbation cup, the woman's moaning in the headphones, the automatic sucking of the masturbation cup, and the occasional car driving by on the street, all of this made me feel so good. Just when I was about to ejaculate, I suddenly heard someone talking around me. I was so scared that I stopped all my movements. Fortunately, they were just passing by. But when I thought that someone might see me naked at any time, I was filled with joy. I can say I will never forget the feeling of that last moment of ejaculation. Oh my god, now when I think about it, I really want to try it again.
