It was a hot summer afternoon, and the local gym was packed with sweaty bodies. Among them was Jack, a muscular man in his late twenties, who had just finished a grueling workout. He headed to the locker room to shower and change.
As he entered the locker room, he noticed a petite teenager sitting on a bench, nervously looking around. She was a stunning beauty with long blonde hair, bright blue eyes, and perky breasts. Jack couldn’t help but stare at her, and she glanced up, catching his eye.
“Hey there,” Jack said, walking over to her. “I’m Jack. You look a little lost.”
“I’m Lily,” she replied, blushing. “I just turned eighteen today, and this is my first time at a gym.”
Jack smiled warmly at her. “Well, happy birthday! Let me show you around.”
He showed her the showers, sauna, and other facilities, and they chatted as they walked. Jack couldn’t deny his growing attraction to Lily, and he could tell she felt the same way.
After they finished their tour, Lily hesitated for a moment before speaking. “Um, do you think you could help me wash my back in the shower?”
Jack grinned, feeling his cock stir in his shorts. “I’d be happy to.”
They headed to the showers, and Jack turned on the water, adjusting it to a comfortable temperature. Lily stepped under the spray, and Jack joined her, soaping up her back and shoulders.
As he washed her, his hands began to wander, caressing her breasts and ass. Lily moaned softly, pressing her body against him. Jack could feel her nipples harden under his fingers, and he knew she wanted him.
He turned her around, and they began to kiss passionately, their tongues exploring each other’s mouths. Jack reached down, cupping Lily’s pussy through her wet bikini bottoms. She gasped, grinding against his hand.
Breaking their kiss, Jack knelt down, pulling Lily’s bikini bottoms to the side. He began to lick her pussy, teasing her clit with his tongue. Lily moaned louder, her hands gripping his shoulders for support.
Jack stood up, and they resumed kissing. He reached down, stroking his cock through his shorts. Lily noticed and reached down, pulling them down, freeing his hard cock.
She began to stroke him, and Jack moaned, feeling his orgasm build. He pulled away, and Lily looked up at him, confused.
“Turn around,” Jack commanded, and Lily obeyed, bending over. Jack positioned himself behind her, rubbing the head of his cock against her wet pussy.
He thrust into her, and Lily cried out, her pussy tight around his cock. Jack began to fuck her hard, gripping her hips as he slammed into her. Lily moaned, pushing back against him.
Suddenly, Jack pulled out, cumming all over Lily’s ass and back. She looked back at him, surprised, as he stroked his cock, milking every last drop of cum from it.
“Happy birthday, Lily,” Jack said, grinning.
Lily smiled, standing up and turning around. She reached down, scooping up some of Jack’s cum and licking it off her fingers.
“Thank you, Jack,” she said, grinning back. “That was the best birthday present ever.”
