Whoa, a lot of people. That was the first thing that Jack noticed was that there was a lot of people. He hadn't really counted on other people being here, maybe a few others, but by the looks of it, this party was booming! And he would take advantage of that. He walked through the people, his wand in a small pocket on the inside of his bathing suit. Which was the only thing he was wearing besides a yellow shirt with a sun on it, and a wooden beaded necklace.
Jack stepped around the beach, looking for Cecilia, while wiping his forehead. It was burning him, the heat.
"Ah, screw it."
Jack pulled off his shirt, revealing his toned chest and pecs. Despite being barely 17, he had already started working out and had a Muggle job as a lifeguard. He bunched up his shirt and threw it at the ground, looking at it. He didn't really care, it was a beach, he would probably find it somewhere soon. He made sure his wand was secure in his pocket, before walking down to the waterline, and, not hesitating, began walking out into the water, not halting as the water creeped up his body.
