Risky sex in public outside. Sucking, ejaculating in mouth, swallowing

Walking through an abandoned and closed medieval castle, I thought we would be alone to take a few photos. After crossing the forbidden zone, we walk around the castle to identify the best places to take photos. When suddenly, opening the door of a tower, we come across a couple. She is sucking him. We stay watching, they don’t stop, and after a few minutes, she stands up and sits on his cock. We then take a step back, and I decide to suck Alex right next to it. Excited by the situation he quickly ejaculates in my mouth and I swallow it all. As usual, I don’t waste a drop.
