Never!

"Hey, you should join us!" Lauren calls out from the poolside, where she and a group of other women are playing a casual game of beach volleyball. "We need more players!"

John looks over at them, his eyes lingering on the way the wet fabric clings to their bodies. He's only half-hard, but he's aware of the way his g-string is molded to his growing erection. He takes a deep breath and nods, walking over to the net.

The game starts, and John tries to focus on the ball, not the way the women's bodies move in their swimsuits. Every time he jumps to hit the ball, the g-string tightens around his cock, sending a thrill through him. It's not uncomfortable, but it's definitely noticeable. He keeps his eyes on the prize, trying not to think about the fact that any one of these women could see him at any moment.

But as the game goes on, the 'accidental' brushes become more frequent. A hand 'accidentally' grazes his ass, a foot 'accidentally' knocks into his crotch. Each time it happens, John's cock swells a little more, until it's straining against the flimsy fabric of his swimsuit. He tries to ignore it, to keep playing, but it's getting harder and harder to concentrate.

The next time it happens, it's Amanda's hand that brushes against him, her fingers lingering for just a moment too long on the bulge in his suit. She giggles and pulls away, her eyes wide with innocence. "Sorry," she says, her voice sugary sweet, "I'm a bit clumsy."

John nods, his voice tight. "It's okay," he says, trying not to look at the way her breasts are bouncing in her bikini top. He can feel his cock pulsing.

Then it's Linda's turn, her wet, slippery body sliding against his as they both dive for the ball. She laughs as she bumps into him, her hand landing right on his crotch. "Oops," she says, her eyes flicking down to where her hand is, then back up to his face. "My bad."

John's face is on fire, but he manages a smile. "It's fine," he says, his voice strained. He's definitely hard now, the fabric of his g-string stretched to its limits. The women are pretending not to notice, but he can feel their eyes on him.

The last straw comes when Jenny 'accidentally' spikes the ball right into his crotch. He doubles over, the pain momentary but intense. "Oh my god," she says, her hand flying to her mouth, "I'm so sorry!"

John stands up, his cock deflates a bit with the pain, but the fabric of his swimsuit is still tight. The women around him gasp, their eyes wide, but they quickly look away, pretending nothing is amiss. "It's okay," he says, his voice a little shakier than before. "I just need to... sit down."

He heads over to a lounge chair, his cheeks burning as he tries to cover up. The women around him murmur, their eyes glancing over at him, then away, as if they're trying not to stare. He can feel their curiosity, their excitement, and it only makes him harder. He sits down, his cock slightly tenting the fabric, and takes a deep breath.

Sara brings him a towel, her eyes not quite meeting his. "Are you okay?" she asks, her voice soft.

John nods, his voice muffled by the fabric of the towel. "I just need a minute," he says, his face buried in the soft material.

Sara squeezes his shoulder, her touch gentle and understanding. "Take all the time you need," she says, before walking away.

Jenny comes over, her eyes full of concern. "John, are you okay?" she asks, her voice sincere. "I'm really sorry about that. Did I hurt you?"

John shakes his head, his face still buried in the towel. "No, it's fine," he mumbles, his voice muffled. "It's just..."

"Let me see," Jenny says, her voice firm but kind. She takes the towel from him, her eyes going wide when she sees the state of his swimsuit. "Oh," she says, her voice barely above a whisper.

John's face is on fire. He can't believe this is happening. "It's not what you think," he says, his voice a squeak. "It's just... the water... and the... the... "

Jenny's laughter is light and airy, like a summer breeze. "Oh, John," she says, her hand on his shoulder, "it's okay. We're all adults here." She nods towards the pool, where the other women have resumed their game, their glances at him now more sly and knowing. "With all these gorgeous women around, it's only natural for you to get a little... excited."

Her eyes sparkle with mischief as she leans in closer, her breasts brushing against his arm. "You're not the first man to get a little hard at a party like this," she whispers. "And you certainly won't be the last."

John swallows hard, his cock still tenting out his swimsuit. He can feel the fabric sticking to his skin, and he's pretty sure everyone else can too. But Jenny's words are a balm to his burning embarrassment. Maybe she's right. Maybe it's not so strange.

He looks up at her, his eyes searching hers. "You're not going to tell anyone, are you?" he asks, his voice low.

Jenny's smile widens, her teeth white and perfect. "Your secret is safe with me," she says, her voice a purr. "But maybe you should consider getting into the water again. It'll help with... you know."

John nods, his heart racing. He stands up, the towel still clutched in his hand. He can feel the eyes of every woman at the party on him, but now, instead of feeling ashamed, he feels a strange kind of power. He's the center of attention, and while it's humiliating, it's also exhilarating.

He takes a deep breath and heads back to the pool's edge. The water calls to him, promising relief from the heat and the pressure of the moment. He dives in, the coolness washing over him like a wave. He can feel his cock shrinking, the fabric of his suit loosening around him. He's safe here, underwater, where no one can see.

But when he resurfaces, he notices a game of twister has started up on the lawn. The women are laughing and shouting, their bodies twisted into impossible positions. He watches from the water's edge, his heart racing as he realizes that he's the only one not participating. They're all looking at him, their expressions a mix of encouragement and challenge. He's not sure he can do it, without embarrassing himself, but something about the way they're looking at him makes him want to try.
