An answer from above

As if on cue, a shout came from above. "Hey, bro!" Josh craned his head to the mall's second level, and he found his sister Molly bent over the railing with some huge, muscle-bound guy ramming into her from behind. Her jeans lay bunched around her ankles and her shirt was pushed up over her bra-bound tits. One of the guy's meaty hand pawed at one while the other grasped her waist, almost wrapping around it. Her faced flushed and her hair was mussed, but she still had the energy to shout and wave at her brother.

"Come up here! I'm almost done-- Ohhh!" Muscle man redoubled his efforts and Molly's tits heaved in her bra.

Josh scrambled up the nearby stairs and ran to meet his sister. Not a moment to soon, as muscle man grunted and shoved his cock hard into Molly's cunt. Molly smiled, feeling the man's warm cum gush into her. Josh arrived to see muscle man withdraw and slowly gather his things.

"Thanks, sweetie," Molly said and kissed the man on his cheek. He blushed, something Josh found odd, and saw the man scamper away like a child just given a candy bar.

"Sorry about that," Molly said to Josh, still smiling broadly. She flipped her hair with her fingers, magically restoring its freshly styled look. She grabbed her jeans, almost reluctantly pulling them up. But not before Josh could see her just-fucked pussy and the cum dribbling out of it. Josh flushed, and felt his cock stir.

"N-No prob sis," Josh said. "Why'd did you wanna see me?"

"Awww, a sister can't say hi to her brother?"

"I didn't say that."

Her smile spread again, and her stare gained a clear focus. On him.

"Just... teasing, big brother." She purred. She took his hands and slowly began running her hands on his arms, kneading his biceps.

"Molly..?" Josh's voice cracked.

"Big brother, you know what today is right?"

Josh grinned. "Your 18th birthday! Well, you've gotten it off to the great start."

Molly's hand ran under the sleeves of his shirt now. Moans and screams came from all around them, and Josh's cock hardened to steel.

"He was nice... Not as nice as the first guy, but nice..."

"First guy? Damn sis."

Molly chuckled. Her hands now slide to his stomach and up his shirt. "It's my 18th, I going to enjoy it." Her hands grabbed his back and pushed him towards her. Josh's hands found her waist, then traveled north for the swell of her boobs. "But I only did them because... well, I couldn't find you, big brother."

Josh smiled again. He saw long ago that his wish had been confirmed, and now enjoyed groping his little sister, something just yesterday he never imagined doing.

Josh slipped his hands underneath her bra, and gently tweaked her nipples. Molly moaned, eyes rolling into her skull.

"Little sis..." Josh groaned.

"I've haven't cum..." Molly uttered.

"What?"

"No one's made me cum yet..." Her hand snaked into Josh's pants. "Makes me cum, big brother."
