The salty sea air fills his nostrils as he lies there, helpless, his cock throbbing in her firm grip. She leans in, her breath hot on his ear, "Don't move," she whispers. He feels her fingers dip beneath his waistband, wrapping around his bare cock, pulling it free. He gasps as she begins to stroke him, her touch sending electric shocks through his body. He can feel the eyes of the strangers around them, their curiosity turning into lust as they watch the scene unfold. He knows he should stop her, but the exhibitionist thrill is too intense, and he surrenders to her touch, his body tensing as he nears his climax.
