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.
"Not as long as you keep doing that," she sighed as Jill played with her nipples. Her fingers were leaving trails of white foam as they pinched and swirled around.
She slid one hand back down, circled Kris's belly button, and cupped her pussy. Kris moaned softly as Jill started to rub her clit in slow circles. Her other hand still played across her sensitive nipples. On top of that, Jill began to kiss her shoulder and neck.
Between all of the things going on, Kris couldn't decide where to concentrate. The warm water and soft massage on her breast felt amazing; her hips were swaying in an unconscious effort to grind on her sister's fingers; and now Jill was sucking on her earlobe. Just when Kris was beginning to get weak knees, it stopped.
"Why'd you stop?"
"All the soap rinsed off."
"So?"
"Can't get clean without soap."
Kris rolled her eyes at this, which Jill didn't see. She lathered more body wash between her hands and lowered them, cupping the luscious butt in front of her.
"Did I ever tell you that you have a very sexy ass?"
"Yes."
"Well, I'm telling you again," Jill said, lathering it carefully.
One hand crept around front again, much to Kris's delight. Its slow pressure on her clit continued, now and then stopping in order to slide two fingers up and down the length of her slit. It was hot and slippery underneath the running streams of water. So hot and slippery that Kris hardly noticed when Jill slipped one finger inside her. The second, she did notice. When they started to stroke slowly in and out, she noticed loudly.
The hand that had been cupping and massaging Kris's smooth ass now sneaked a little father between her cheeks.
Though Kris was enjoying herself, she became a little nervous when she felt her sister's fingertips rubbing lightly at her asshole.
"Relax honey, I'm not gonna do anything here."
"Promise?"
"Of course." Jill kissed her neck again. Her fingers stroked slowly in and out of her sister. She knew just the right pace -- just enough to keep her excited but not enough to get her off. She was back in her groove in no time.
Kris had to admit that the little teasing pressure on her asshole was exciting. She'd wanted to try this for a while, largely because she knew her sister loved it and she wanted to share the fun. So far, it felt great.
She rocked slowly from side to side, feeling her Jill's warm body pressed up against her back. Two little hard points poked into her shoulder blades. She loved Jill's nipples and she loved knowing that they were hard just because of her, all for her.
Jill slowed her fingers a little, sensing that she was near orgasm.
"Oh, come on," Kris begged.
