Dave stood dumbfounded. What the hell had just happened? He gathered himself, becoming aware again of his own nudity. He looked up at Miss Beckett, who was smiling, almost shyly, at him. He tore his mind's eye away from the three naked eighteen-year old bodies that had stood before him not sixty seconds earlier, and turned to the pool. He saw a small dark patch that must have been his trunks about halfway up the pool, resting at the bottom.
Dave turned and slid slowly into the pool. As he turned, Alice got a clear view of his arse. Muscular and toned, she couldn't help but stare at his pale buttocks, glistening wet. He had to use both hands on the edge of the pool, and turned as he dropped into the water. Alice got a quick, but unobstructed view of Dave's cock. She couldn't help but think it looked bigger than she remembered. Dave kicked off the wall, and swam to the middle of the pool, his bare backside kissing the surface of the water. He stopped, and trod water for a few seconds searching for his missing clothing. He took a deep breath, and dived beneath the surface. As he did, his arse broke the surface, and Alice, still staring realised she had stopped breathing. She took a deep breath as he disappeared from view, and gathered herself. All of a sudden she felt very hot. She fanned herself with her hand, and strode back towards her paperwork at the other end of the pool. She had just placed it all back in her bag as Dave clambered out of the pool. As he pulled himself up, he caught his still erect member on the edge of the pool, and it slapped against his stomach as it came free. Alice was staring again, she couldn't help it. Stark naked, Dave pulled himself out of the water and hurried to put his speedo on. He saw Miss Beckett openly staring at his dick, which only served to make his cock harder, if that was possible.
He slid his trunks over his arse and crotch, and his heart sank. The speedo did not do much to cover his erection. About half of his member still poked over the top of the waist band. Miss beckett bent down, and picked up the one remaining towel on the bench next to her, and walked slowly over to him.
'Here,' she said softly, 'I think you might need this.'
Dave took it, and wrapped it around himself.
'Thank you.' It was all he could say. He walked past her, and into the empty changing room.
Alice watched him leave, and sighed deeply as the final bell of the day rang. Students and teachers alike would be heading home. She still felt very hot, and slipped off her track bottoms and dived head first into the cool water. It felt good on her skin. She decided, that as she was here, she'd get a few laps in, and try to gain control of herself again.
Dave stood in the empty locker room, and patted himself dry. He tried to get the thoughts of the last little while out of his head, willing his erection to go down, but it just wouldn't. No matter how hard he tried, he just couldn't lose his erection. He sat, naked again, on the bench in the middle of the room. He laid his towel over his knees, with a conspicuous tent in the middle, and buried his face in his hands.
Alice front-crawled her way through several laps, her mind racing. She could get in so much trouble for what she had done. She had forced three young girls to expose their naked bodies to another student. Sure, they had done the same to Dave, but no one would excuse her of this if anyone found out. She paused for breath at the edge of the pool, clinging on to the wet tiles. It was here, and now, she made her decision.
'In for a penny.' She muttered under her breath, and clambered out of the pool.
