Ty left the changing rooms and made her way to the part of the beach where the volleyball nets were set up- only to bump into a man who laughed playfully and said, "You OK there, babe?"
She looked up to see a young man called Caleb, who smiled down at her. He had a handsome face, a firm jawline and cute messy hair, and at the moment he wore nothing but a pair of red and white swim shorts and a pair of sandals, with a bag in one hand.
Slowly memories flowed into Ty's head, and she realized Caleb was her boyfriend. He worked as a lifeguard on the beach, and they'd met one day after she'd finished a game and he'd finished his shift, hit it off and begun dating after getting to know each other. And they knew each other well, as he showed by cupping her soft cheeks and pressing his lips against hers. She felt her body respond eagerly to his touch, her nipples tenting her bikini and a little moisture welling up between her legs. Likewise, she could feel a bulge growing in his shorts as he pressed against her.
"I've got a few minutes before my shift starts," Caleb whispered once the two of them finished their kiss. "Want me to come... help me prepare?"
"Of course," Ty smirked, holding his hand as Caleb pulled her back to the changing room where he had just turned himself into a girl. It felt strange, and yet extra arousing, to reflect that what Caleb was gonna do to her was something he never could've or would've before Ty used her power to transform herself.
Caleb pulled down his shorts and stood naked in front of Ty, his large erection before her, then reached to remove her panties while Ty pulled off her top. They kissed passionately, and Caleb pushed himself inside her. Ty felt herself stretch to accommodate him as if he'd fucked her loads of times, and yet it all felt new to her, used as she was to a boy's body.
Speaking of which, seeing a boy's muscles flex as he pounded her was so enticing, she'd never felt like boys were that hot but now her body was making her understand so clearly. Caleb pulled away and before she could let out any moans of pleasure, he shoved his hand over her mouth and she sucked mindlessly on his fingers. Clearly he knew she was loud when having sex.
Ty clung to Caleb with her arms and legs, his own playing with her and escalating her pleasure, one moment rubbing and pinching her nipple, the next reaching down to stroke at her clit. And fuck, he felt so good inside her, thrusting in and out vigorously, his cock finding and brushing along her most sensitive points and his balls slapping at her crotch with each thrust.
At last, and in almost perfect sync, they hit their peaks. Ty whimpered around Caleb's fingers as she felt her body quake with her first female orgasm, and she felt him press as close as he could to her and stiffen as she felt him release warm, thick spurts of cum inside her, her tensed walls making him give her as much as he could muster.
While Ty recovered, she felt Caleb kiss her, pull up his shorts and prepare to go, saying "Thanks for that, babe. Good luck with your game! Love you!"
