Susan whimpered, and returned the pressure by arching her cunt high, grinding as Wanda licked and sucked.

When she realized Wanda was moving her knee closer to her head, Susan didn't protest. She didn't protest as her sister lifted her knee and spread her legs around her head. With Wanda thrusting her tongue in and out of Susan's boiling cunt, fucking around her knotted clit, holding her ass tightly with both hands, Susan found herself staring up into her sister's crotch. Wanda's inner thighs were creamy smooth, the crotch of her skimpy panties tight and stretched over her cunt. She saw the white of Wanda's asscheeks where the sun had failed to tan them. Blond hairs curled from the edges of the panties.

Wanda buried her face into Susan's cunt, sucking harder, her uplifted ass writhing. She lapped her tongue up and down, tasting Susan's seeping juices, then she swirled her tongue about her inflamed clit, finally taking it between her hot, greedy lips. When Wanda began to suck, gently yet with fiery desire, Susan pumped her crotch up hard, grinding. Wanda made a purring sound as Susan's hand caressed up her thighs.

Susan gazed into Wanda's crotch, her hands cupping the firm cheeks of her pretty ass, feeling the heat coming through her tight panties. She licked her lips, eyes glazed. She didn't think of what she was going to do.

Then she pulled Wanda's hips downward.

Wanda rubbed her face up and down her sister's cunt, moaning softly as she lowered her crotch. Susan felt the moist heat of Wanda's cunt against her mouth before it touched. The crotch of Wanda's panties were wet, soaked, really. The juices seeping through, burned against Susan's lips, urging her to taste, touch, kiss, lick.

But Susan didn't lick, not yet.

The scent of her sister's hot cunt worked in an erotic way on her. She parted her lips slightly, keeping them pressed at the panties. The tip of her tongue touched the nylon, and drew back.
