The sea's rhythm echoes the pulse between Max and Emma as they paddle out, their bodies mere inches apart. Emma's nipples harden against the cold water and Max's gaze, her brother's eyes lingering on her chest longer than they should. The waves lift and drop them, their bodies brushing, sending electric jolts through them. As they catch a wave, Emma's hand grazes Max's crotch, feeling his hardness. Their eyes meet, and the unspoken confession hangs heavy in the salt air, their secret desire ready to spill over like the incoming tide.
