Brother-sister rimming

I stepped quietly toward the Langfields' back gate, suspecting that brother and sister Sal and Sally were up to some hanky panky together. After all, they had been grabbing each others' asses right in front of Lisa and me. And when I caught up to them on the hillside, Sal's hard cock had been poking out of the leg of his running shorts.

I figured I'd take a peek to see what they were doing (probably nothing, just my overactive imagination). Then I'd jog over to the convenience store for some ice cream to take home to Lisa.

As I stepped up, I heard a rhythmic sound of moist flesh on flesh. Sal groaned softly, and Sally hummed back with a rising note. I put my eye to a gap in the wooden gate and twitched in surprise.

Sal and Sally were only a few feet away, out of sight of the house in a sheltered corner behind a shed. Sal's shorts were down around his ankles, draped round his running shoes. His butt was rather paler than the rest of his bronzed skin. He was bending forward against the shed, resting his weight on one forearm. His other arm caressed Sally's hair as she sat in front of him, rubbing and kissing his erect cock. She spat in her hand and rubbed the moisture up and down his shaft.

"You dry up so quickly on a day like this," Sally said, "There we go, a little pre-cum. Nice and slippery." She smiled and rubbed the drops from his cock tip round the head and onto the shaft. She gave him a few more hand strokes, twisting a little this way and that. "Now we've got you warmed up, time to try it out. Gotta be hot already, otherwise it just tickles."

"Whatever you say," Sal said. "Feels good so far."

Sally slipped out from in front of her brother and kneeled behind him. She took her thumbs and rubbed them on the root of his cock shaft behind his balls. Sal groaned happily. Sally kissed his balls. He let out a little laugh. Then she stuck out her tongue and ran it from his balls up his cock root to his butthole.

Sal quivered. "Whoa," he said.

Sally kept licking, up and down and round and round. Sal shivered, the ripples running through his long bronzed limbs. His erect cock twitched and oozed pre-cum.

"Oh wow, stop, you're gonna make me come," he said.

"What did I tell you?" Sally said. "Now you do it to me."

"I guess it's fair," Sal said. He stepped out of his shorts, leaving him wearing T-shirt, socks, and shoes. "Who'd you learn this from?"

"I read it in one of Mom's books," she said. "But actually I learned it from Dorothy across the street. You know, the short one who's kinda like a cowgirl?"

"Yeah," Sal said. "Is Isabelle the gypsy looking one, and Arielle's the blonde?"

"Yeah. The three witches and their garden," Sally said. She pulled down her shorts to her knees and kneeled down on them, bending forward to rest her head on her folded arms. "Do it, Sal," she said.

"Okay," he said. He ran his hands over his sister's tight buttocks, squeezing and kneading. "I love your ass, sis. I guess I can lick it. D'you think Steve and Lisa saw me pat your butt?"

"Duh-kay," Sally said. "Of course. I thought you did it on purpose to show them. That's why I grabbed your ass in front of Steve."

Sal took one hand and ran the fingers up and down Sally's red-furred pussy lips, pressing, caressing with his fingertips.

"You're getting good at that," Sally said. "Mmmmm."

Sal opened his sister's outer pussy lips and stroked her damp inner folds. I caught a glimpse of her swollen clit, big and round as a fingertip.

"Ooooh," she said.

Sal turned his head sideways and tongued Sally's wet, open pussy lips.

"Aw...." she sighed. "Oh yeah. Just a little more." She tilted and rolled her hips gently at the touch of his tongue. She twitched. "Ooh, go easy there." She turned her head round toward Sal, but her eyes met mine looking through the gate.
