A casual swim

Anna dove into the lake, disappearing under the surface with a splash. David hesitated for a moment, but then followed suit, feeling the cool water envelop his naked body. The water was refreshing, washing away the heat of the day and the awkwardness of the moment. David's semi-erection quickly dissipated as he swam deeper into the lake, feeling the pressure of the water on his skin.

Anna swam out further, the water reaching up to her chest, and let out a scream of joy.

"See? It's not so bad, is it?" Anna asked, her eyes sparkling with mischief.

David shook his head, trying to keep his gaze fixed on Anna's face and not let it drift downwards. "No, it's not," he replied, trying to sound casual. But his focus quickly switched as the bottom of the lake proved to be surprisingly slippery. Anna, in her enthusiasm, didn't notice and stumbled upon the slick surface. In an instant, David's instincts took over, and he lunged forward to catch her before she slipped beneath the water.

His arms wrapped around her waist, and they both tumbled into the cool embrace of the lake. David's heart raced as he felt her soft curves pressed against him, the water swirling around them. He could feel her breath against his cheek, and he looked into her eyes, which were wide with surprise.

"Thank you," she whispered, her voice barely audible over the sound of the water lapping against the shore. "I-I didn't see that coming."

"No problem," he replied, trying to keep his voice steady. But as he held Anna close, he realized something else - his erection had returned and was pressing into her leg. David felt his face grow hot with embarrassment, and he quickly released her, taking a step back.

Anna laughed and shook her head. "It's a good thing you were close to me. Your third leg did a great job keeping us stable out there."

David blushed even deeper, unsure of how to respond. Anna just winked at him and started walking away, leading him closer to the shore into the lake. "Maybe it's safer here, let's avoid the deeps for a moment."

She stopped when the water was at her waist level. She turned around and David couldn't help but notice the way Anna's swimsuit clung to her body, revealing the curve of her breasts. David hesitantly followed her and shortly he felt the light breeze on the head of his penis. He looked down and noticed that while the head was above the water, even the rest of his penis was still clearly visible.

David hesitated for a moment, not wanting to show off his naked privates to the girl of his dreams. He considered covering up or backing out, but then looked at Anna who didn't seem to notice. Her gaze fixed on the horizon and as she continued to ramble about some boyfriend troubles of one of her friends. He decided to just go with the flow and not call attention to his clearly visible junk.

Suddenly, Anna let out a shiver. "I'm getting cold," she said, her teeth chattering.

David couldn't help but notice that her nipples were poking through the fabric of her bikini top. He quickly looked away, feeling his face grow hot with embarrassment.

"Yeah. I think it's time we get out of here," he said, trying to keep his voice steady.

Anna made an exaggerated surprised face. "Thanks, but if you want to stay longer, feel free to do so. You don't seem to be cold to me."

David blinked, caught off guard by her observation. "What do you mean?" he asked, trying to sound casual.

Anna gestured towards his body, a playful smile on her lips. David felt his face grow hot with embarrassment as he realized that Anna had been aware of his growing arousal the entire time.

"You were so nervous at first I though maybe it was wrong for me to push you to try something now," Anna continued, her eyes holding his gaze. "But I'm glad you're more at ease now. "

David took a deep breath and tried to keep his voice steady. If Anna was totally oblivious to his nervousness then he should keep the lie. After all, she sounds like she would be disappointed if she knew how nervous is his nudity making him. "Y-yeah, you're right. I almost for-forgot I was naked while talking to you" he stammered.
