Once they finished eating breakfast, Daddy helped them clear the table and clean up. Then he told them, "Go get dressed. Just a casual top and skirt."
"Just ordinary stuff?" Jenny asked.
He smiled and nodded. "Nothing fancy. Hmm..."
After contemplating then for a moment, he added, "Why don't you go no bras or panties?"
With giggles, they headed to their rooms to choose their outfits. Tammy had donned a pretty v-neck blouse and denim skirt, but Jenny decided she had her beat with her lightweight vest top and pleated short skirt. They both had chosen open-toe sandals.
Daddy nodded his approval and they headed out to the Range Rover..
"Both of you in the back seat," he told them. "You can play with each other a bit if you want."
Tammy gave out a short giggle and waggled her eyebrows at Jenny. Since she grabbed the driver's died, Jenny got in on the passenger side, but right after Jenny buckled her seat belt, she hopped over into the middle seat.
"Tammy?" Jenny asked, wondering if she was seriously going to 'play'. She got her answer right away; just after Daddy pulled out into the street, Tammy twisted to face her and began nuzzling her neck. Before Jenny realized it, her little sister's hand was sliding up her right leg.
"Omigawd, seriously?" she asked, and Tammy giggled again.
"Just making sure you followed instructions," she teased, and her fingertips reached Jenny's hip. Her thumb lightly slid across Jenny's unprotected pussy.
"Ooh, yeah, looks like Jenny's a good girl," she purred. "Just one more thing to check."
Jenny remained motionless, too amazed to do anything, as her little sister slid her hand out from under her skirt and then slipped it under her blouse to gently caress her tummy.
"You've done this before," Jenny concluded, and Tammy giggled again.
"I'm a cheerleader," she laughed into Jenny's ear. Her hand was slowly slipping farther up beneath her top. "I'm surrounded by hawt, oversexed babes every afternoon. What do you think?"
By the time Tammy was cupping her breast, Jenny's nipples had become swollen and hard. She noticed she was starting to breathe so deep her head was beginning to spin.
"Oh, gawd," she moaned, then turned her head toward Tammy's and planted her open lips over the girl's mouth. Tammy's tongue began to gently search for hers.
Jenny groaned and then grabbed the back of Tammy's head to force her into a stronger kiss. She tried to grab Tammy's hand and press it into her breast, but Tammy evaded her and left her groping herself. Her little sister helped out by pulling Jenny's blouse up so she could fondle skin instead of fabric.
Before she knew it, the nimble hand had slid back under her skirt and found her love nest again. Her fingers began softly caressing the outer lips.
Jenny broke way from the kiss and demanded, "More, dammit!"
She urged Tammy's head downward, so the girl replaced Jenny's fingers with her mouth, suckling her aching breasts with enthusiasm. Jenny used the now-freed hand to press her sister's fingers more firmly into her, opening up to allow better access.
As another moan escaped from her, she noticed that they were at a red light. Daddy smiled over his shoulder but didn't say anything. She drew in a deep shaky breath and sneaked her rump forward, then began wiggling her hips in response to Tammy''s explorations.
Tammy unlatched from her titty and looked up. With a wicked look in her eyes, she asked, "Want me to get a little more serious?"
She could only answer with rocking hips and another groan. Tammy giggled and slid her middle finger inside, her thumb playing with her hard clit as she resumed sucking her breast.
Jenny finally counterattacked, pulling up the hem of her sister's top, then laughing and pulling the garment off her completely. Tammy only broke away long enough to let her blouse pass, returning to her happy nursing immediately. Jenny dropped the blouse on the seat, then took her now-topless sister's oversized melons prisoner, fondling them with lover. Soon she began bucking gently against the fingers inside her.
Daddy looked at them in the rearview mirror with another smile. "Why don't you take yours off, too, baby girl?"
She grinned back at him and pulled her own top off. Tammy laughed and got her out of her skirt as well. She was now bare-naked, and her little sister was licking her way down her tummy to begin teasing her mound. The girl pulled her older sister's legs further apart to make enough space to get her head between her thighs.
Jenny unhooked and unzipped Tammy's skirt as well. While Tammy was pulling the garment the rest of the way off and dropping it in the pile with the rest of their clothing, Jenny noticed they were entering the highway. She wondered where they were going, and whether Tammy had enough time to finish. But she didn't waste much thought on it. She just began grinding into Tammy's face without caring.
"How's she doing?" Daddy asked.
"Wonderful," Jenny purred. He chuckled again and kept driving.
