It was obvious he had no idea what was happening to him. She could feel his cock pressing against her thigh. She worked her hips up and down, letting him feel the pink tip of her tongue. She pretended to weaken and fall across his bed, somehow managing to pull Kevin with her. He was really mixed up now, but she kept petting his body, kissing his lips open a little. Sooner or later he'd have to get the message, wouldn't he?
"Oh, you beautiful man, you!" she breathed, nuzzling her short nose down into the hollow of his neck. She scratched his shirt open and ran her fingertips across the smooth, tan surface. It rippled as he tried to get up. Vicky threw a leg over one of his and touched her slightly parted lips against his chin. She was a little ashamed at being so aggressive, but she was burning up with want. Watching Carl sock it to his own sister had gotten her blood to boiling. She wanted a little fun for herself. At fifteen she was still really a virgin. And she didn't want to remain one much longer.
"Ohhh Kevin, Kevin… kiss me!"
Kevin made a sound. It was like a word that didn't quite work. A word of fear maybe or uncertainty. Vicky knew how to get rid of uncertainty. She pushed the flat of her palm down his belly, down, down. She slipped fingers under the elastic of his shorts. But even as her fingers curled under the throbbing hardness of his white cock, it began to soften. Kevin made another little sound and tried to rise from the bed.
"Oh darling, don't do that," Vicky gasped, squeezing and massaging the dying shaft. But now it was just a little soft snake. The fever had gone out of it and all the stiffness. She could hardly believe that her own foolish bumbling had done that. Kevin jerked her hand from his pants and sat on the edge of the bed, breathing hard. He wouldn't look at her, wouldn't let her touch him.
