Kris watched her sister masturbating. Since they had become lovers, they hadn't wasted much time watching each other masturbate. Kris had heard it every night for years and years, but she hadn't seen it happen more than once or twice. It was a lovely sight to wake up to.
It would have been an even lovelier sight for a third party. The girls both had thick curls of shining blonde hair, and perfect, dazzling smiles. Even though they were a few years apart, people occasionally mistook them for twins. In the dark, they could only be told apart by their breasts. Jill had bigger nipples, and Kris had bigger breasts. In the light though, they looked like two matching Barbie dolls when they stood side by side.
Jill was naked, just the way she usually slept. Her legs were parted and she was rubbing herself with her old red dildo. She would sink it into herself, slowly and lazily pull it out, and rub the wet tip on her clit. Then she would dip it inside again, getting it glazed with juices, and slide it down to her ass. After teasing her hole for a minute or two, it would go back inside.
Her free hand wasn't doing anything, except when she reached between her legs for a moment, and then brought her fingers to her mouth. Then it flopped back at her side and continued doing nothing. Her eyes stayed closed and she wore the faintest of smiles.
Kris half-slept and half-watched for a while, eventually alerting her presence with a yawn. Jill looked over at her, not stopping.
"Hey."
"Hey," Kris answered. She kept watching as Jill pushed the dildo into her ass, rubbing the just thick tip inside her tight hole.
Kris reached over and touched her sister's inner leg, running her hand smoothly up and over until her fingers were wet. She started to stroke Jill's pussy. Her fingers trailed lazily, like when she twisted a curl of her hair while in deep thought, not all paying attention.
Now and then, her fingers would get bumped by the dildo. Finally she grabbed it and pushed it all the way inside her sister. Jill gasped slightly as it started to move in and out of her. Her hips pushed slightly against it.
"Put it back in my ass," she directed. With a wet pop, it pulled out of her pussy and pressed up against her ass. Kris was trying to ease it in, but Jill had no such patience.
"Just put it in, Kris."
"I didn't want to hurt you," she explained, pressing harder.
"You won't hurt me, just shove it in, I need it."
Against her own feelings, Kris did as she was told and slid the whole toy firmly into Jill's ass.
"Yeahhh," she moaned loudly, folding up her legs for a better angle. "That's it, do it again."
Kris started to pump her sister's ass with every inch. Jill rubbed her clit, doubling her own pleasure.
"Harder," she kept chanting, rolling her hips involuntarily. Her face flushed and she rubbed her clit faster and faster. Kris soon got to see another one of her favorite things - her sister crying out in the pleasure of an orgasm. She wriggled closer and kissed the corner of Jill's mouth as she came.
"You're obsessed with your ass," Kris giggled.
"You would be too, if you knew how good it felt."
Kris stared thoughtfully into her eyes.
"Do you want to try it?" Jill asked.
"Maybe."
"Great, you can start by licking mine clean," Jill replied, opening her legs. She burst out laughing at the hesitant face Kris made.
Kris smiled and wrinkled her nose. "Doesn't it...?"
"Doesn't it what?"
"You know... taste bad?"
Jill chuckled. "Not if you've heard of hygiene." She kissed her again. "That's why a great place to start is the shower."
"What about a bath? I like baths better."
"You know that if we get in a bath together, we'll never get out."
"That's true."
"Let's go."
"Hold on, do you have a... a thingy?" Kris asked, holding her hair up in a ponytail and pointing at it. "I don't want wet hair all day."
"Good idea," Jill said, searching her drawer for scrunchys. She shot one at her sister.
"Thanks," Kris said sarcastically, getting down on the floor to look for it. Jill grabbed at her ass as she walked past.
"Hey!"
Jill giggled and went into the bathroom.
In the shower, Jill poured a little body wash into her hands and Kris's. They stood together in the steam and began to soap each other, starting innocently enough with their backs and shoulders.
Jill stood behind Kris, massaging her back with warm, soapy hands. She ran her hands down her sister's arms, washing and tickling just enough to get a shiver and a giggle. Her hands slid smoothly around Kris's waist, briefly soaping her flat stomach. Soon they migrated upward, cupping and caressing her smooth, full breasts.
"You know, whenever we shower together, only my boobs get really clean," Kris noted with a smile.
"Can you blame me," the reply came back along with a light squeeze on both.
