Jack and Jilling

Standing in the deserted utility pathway, I looked through the cracks in the back gate of the Langfields' house to find out what the rhythmic, moist sounds were. What I saw made me stop and put off my plan to run back home with ice cream.

Bronze-skinned redheads Sal and his sister Sally (Salton and Salina, I recalled) lay side by side on thick beach towels under a wood-slat canopy, thin slices of golden sunlight zebra-striping their naked skin. Their slim young bodies were still damp in places from the run, and the curly dark red hair of their heads looked darker with sweat. Between each one's open thighs was another frizzy puff of dark red hair.

Sally squirted a thread of clear liquid into her palm, and rubbed it into her pussy lips, humming quietly.

"Can I have some more, Sally?" Sal asked. He held out his hand, and Sally squirted some into his palm as well. He closed the hand around his erection and moved it round the shaft and up and down to cover it evenly with slippery fluid. He sighed with pleasure.

"Regular deal, Sal?" Sally asked.

"Sure," he said. "Whoever gets off first helps the other," he said. He smiled, his upturned face not looking at his sister.

"Great," she said. "This time let's not get interrupted."

"Aw, that wasn't so bad," Sal said.

"Not for you," Sally replied.

"Anyway," Sal said. "A little more?" He held out the hand that wasn't already on his cock shaft, and Sally squirted some into that one too. He moved it down to the base of his cock, under his ruddy-tan balls. "Thanks, sis," he said. "Ahhhhh, that's good. Now let's quit talking unless you want to tell me something sexy."

"Betcha I come first, dickfist," Sally said. Her fingers diddled her clit, and from my angle, I could see it, a wet swollen pink marble the size of her fingertip. Her other hand was on her ample breasts, pinching her prominent, dark rose colored nipples. She bit her lip and moaned.

"Oh yeah, clitpicker?" Sal said. His hand moved faster up and down his shaft, stretching the skin up and down, but not touching the swollen, dark pink cockhead. He changed the angle of the hand under his balls, and he grunted "Unnnph."

"Oooooh," Sally crooned. Her fingers flew faster on her clit. Her hand left her breasts to join the other between her legs. Unlike Sal, who was lying back with his eyes closed, Sally was watching intently as her brother masturbated. "Mmmm-hmmm," she hummed.

I caught a flicker out of the corner of my eye. I couldn't be sure, but I thought there was someone else watching Sal and Sally from inside their house.
