Susie

I looked back at my sister. “Well, I guess if you’re going to give me a hard time, then I’m going to pick you, birthday girl. I dare you to lick Carly’s pussy for two minutes.”

“Is this one of your fantasies, David? You think we’re lesbians or something?” my sister asked.

“I thought all girls liked other girls,” I replied. “At least they do in the pornos.”

Susie gave me a dirty look. She got up and came over to my chair and slapped my stiff member. “Yeah, and all guys have twelve inch penises,” she laughed. She made her way on over to Carly.

“Hey, girlfriend,” she smiled at her. “Another chance to show him we don’t need boys? Your pussy need some attention?”

“Can’t say I would mind,” she grinned back.

My sister knelt down on her knees in front of her putting her hands on her thighs and helping her to slide forward so her muff was at the edge of the sofa. She started by placing soft kisses on the insides of both thighs working her way from her knees until almost but not quite touching her soft pussy. Carly moaned and shifted in her seat as Susie teased her, blowing warm breath and light kisses on her legs. She used one hand to finally touch her mound then ran her fingers slowly down to Carly’s labia.

Carly had her hand thrown back and was just kind of humming quietly. She opened her eyes and looked over at me. “Are you taking notes, David? Your sister really knows what she’s doing.”

Susie used her fingers to gently part Carly’s outer lips and bent forward and licked her smooth pink folds lightly with her tongue. Her hands stroked Carly’s inner thighs as she planted her mouth fully on her warm pussy and sucked her into her mouth then used her tongue to tease her swollen clit. Then she would back up and blow on her hot opening before diving back in with her tongue again.

Again, I found myself stroking my steel shaft without even being conscious of what I was doing as I carefully watched my sister working Carly’s hot cunt. I could even see her juices were slipping out of her honey hole on either side of my sister’s mouth.

Much as I hated to do it, I finally had the presence of mind to call “time!” Carly tried to hold my sister’s head where it was but they finally separated themselves. My sister looked over at me with a wry smile as she made her back to her place on the sofa. I looked at Carly and then at my sister and they both were flushed and flustered. I gave her a moment to compose herself, then asked her “who do you pick now, sis?”
