She could not help writhing her ass. She strained her eyes at his cut-offs, directly at his crotch. She knew she was staring, knew that Robert probably saw where she was looking, but Peggy couldn't help it. She couldn't take her eyes away. She could feel his eyes caressing her long, creamy thighs, the swell of her saucy young ass. The cheeks of her ass clenched, and she knew he could see the crack through the wet bikini bottom.

Robert's cock was getting hard. She could see it starting to bulge out. She licked her lips as she saw it growing, then a soft gasp escaped her mouth.

The head of her brother's cock slipped from the frayed edges of his cut-off jeans. She could see it so clearly. It was only a few feet away, and she wanted to reach out and touch it. The head was fully exposed to her hot eyes, and it was smoothly swollen. She could see the piss hole, see it starting to drip. Her hand itched with the strong desire to feel it, caress it, hold it and jack it. Her ass twitched and she pressed her cunt hard into the pad, a soft moan bubbling from her constricted throat.

Robert leaned over in the chair, and she knew where he was looking. Her legs had parted, and the tight crotch of her bikini could be seen by him. Then Peggy gasped.

Her brother had reached out and was running his hand along her thigh, fondling her. Her breath caught in her throat and she tried to be very still, but the ripples of sudden pleasure sent chills flooding her flesh, chills that excited her, made her cunt burn fiery hot. Her clitoris throbbed, and she knew her cunt was becoming wetter than ever before. There was nothing she could do about it. She wanted to tell Robert to stop touching her, to go away, leave her alone. But her cunt was telling him to keep on feeling her, telling his fingers to come higher, to press at her steaming pussy.

Again Peggy's ass moved, wiggling as his hand created delicious sensations on her flesh. He was very close to her bikini now, and she knew the curves of her ass cheeks were exposed.
