Letty leaned against Ruben's bare back and wrapped her arms around his neck to pull him close, pressing her naked breasts tight against him. She closed her eyes and moved a bit to enjoy the friction of his skin on her nipples. When Ruben raised his arms up to reach back he locked his fingers around her neck and pulled her even closer.
"Mmmm," he said, "I want you."
Letty did not reply. She ran her hands downwards pausing to squeeze his pecs and then slid them under the waistband of his shorts and inside the elastic of his briefs. Pulling her head free she bent her knees. She clutched and rolled his balls in her right hand, her left moved to the head of his rapidly growing cock where she used the pad of her index finger to trace circles on the ventral side of his glans. Ruben moaned again and tried to turn and face her, but she resisted and kept drawing circles with her index finger.
"Letty, Letty, honey, you gotta stop," he tried to twist away, but she had his balls. "Letty, I'm gonna cum. I'm not ready to cum yet."
She ran her tongue up the middle of his back, "Baby," she said, "that's the whole idea. Why do you think I snuck up behind you?"
He growled with the first spasm and the cum shot from the end of his cock. Letty kept doing what she was doing. Ruben roared, shook, twisted and spasmed six or seven more times and when he was done she pulled her hands from his pants and rubbed his cum on his chest before she released him and spun him around. She rubbed her tits up and down his body glazing them with his sperm.
She licked her fingers and ran them through his hair as he unbuttoned his shorts and pushed them downward, towards his knees. Letty pushed him down and backwards, until he lay on the floor. She looked at him.
