On this beautiful afternoon, we find sixteen-year-old Dina in her bedroom masturbating. She is naked under the thin silky top sheet and her long dark hair is fanned out on the pillow under her head. She issues a slight intake of air from between her parted red lips as her slender fingers with their painted nails travel down over her firm young breasts and hard and flat abdomen. She issues a slight whimper as her fingers enter the slit between her slightly parted legs.

She is already hot and wet so her fingers slip easily inside. Her practiced hand quickly finds her hard little clit and begins to gently rub it which causes waves of euphoria to wash over her. Dina's free hand moved to her breasts where she gently cups each silky orb. This movement only serves to add to the heat and wetness of her teenage pussy and in between her slight moans and whimpers, she whispers to the lover in her mind.

"Oh yes, that's what I like," she says softly.

She allows her free hand to squeeze her firm breasts in between gently pinching her extended nipples which causes her to moan a little louder and whisper again to her secret lover.

"I've been waiting for this since yesterday," she says softly.

Eventually, she increases the speed of her fingers against her clit causing her to spread her slender and shapely legs a little farther apart and increases her breathing.

"Make me cum," she repeats a dozen times.

A few minutes later Dina arches her back as a massive orgasm begins and she automatically reaches for a small pillow and uses it to muffle her cries.  As her orgasm wanes, she turns onto her side and gently weeps. This is the only way she can have the object of her desire and that knowledge saddens her.

Dina is easily one of the most attractive girls in school and could have her pick of the groups of boys that flock around her and her friends. It was to one of them that she surrendered her cherry, just after she turned sixteen and it wasn't as great as she had been told. They only hooked up one more time after that to see if it got any better. It didn't.

When that student moved away, those left behind were hoping that they would be chosen to fill the void in her love life as he had told many of them about taking her cherry, but they were all wasting their time. The object of Dina's desire and secret lover is her older sister, Dani.

Dani is just as stunning as her younger sister and perhaps even more, but the two girls are just the opposite in appearance. While Dina is dark-haired with dark brown eyes Dani is blond and green eyes. Both girls had a passion for weight lifting, jogging, and gymnastics and as a result, they were both in magnificent shape. Now despite Dani being a year older than her sister, the two are the best of friends and spent a lot of time together.

Most of that time was spent in each other's bedrooms when sleep evaded them. They would crawl under the sheets and share secrets and gossip just like they did when they were little girls. Other times they watched videos on Dina's laptop. These were among Dina's favorite moments. The sight of her sister in a pair of silky sleep shorts and t-shirt sans bra was a treat for her eyes as was staring into her sister's flashing green eyes and beautiful face as she talked. She looked at her sister's lips that were always covered in gloss and wondered what they tasted like.

Sometimes, after the talking and watching online videos ended Dani would fall asleep in Dina's bed, and instead of waking her to return to her own room and Dina said nothing and allowed her to sleep. Those were the best times. The feeling of one of Dani's silky smooth legs brushing against hers as she sought a more comfortable position filled Dina with an almost uncontrollable desire.

More than once, Dani would shift in her sleep and would wind up with her face pressed against Dina's naked shoulder with her chest pressed against her arm. The feeling of her sister's full lips and the warm breath against her silky skin and her braless tits against her arm only added to her arousal. Dina managed to slide her fingers past the waistband of her shorts and into her dripping pussy and gently masturbate, less she woke her sleeping sibling.

These unscheduled visits were the only way that Dina was ever going to get her sister in bed, as normal girls didn't want to get naked and hold and kiss their sisters.  Dina never understood where this desire for girls came from, maybe it was born out of the disappointment she felt after her first male lover.

There were dozens of attractive girls in her school and she knew which were the gay females, but she never approached them as they did not have her sister's looks or personality. Dina managed to survive on masturbation and various fantasies involving her sister. Life was good and school was tolerable but then the pandemic happened and the mandatory quartine.

The girls weren't worried as their Dad was a bit of a survivalist and had stockpiled enough supplies to last them for at least six months. Mom worked from home while their Dad spent his time in the garage finishing the various projects that he had started.

The girls spent their days playing games on their desktops and chatting with their friends after performing the daily chores assigned to them. Many times the girls did not bother dressing and spent the day in their pajamas only bothering to apply makeup.  As always the sight of her sister in her sleepwear only served to turn Dina on.

It was on the third day of the quarantine that Dani appeared clad in a tiny zebra-striped bikini and invited her sister to join her sunbathing.

"We're supposed to stay inside," Dina told her sister as she took in the sight of her superb body clad in this minuscule swimsuit.

"We're allowed to go into our own yard," her sister responded. 

It made sense to Dina so she agreed and headed to her room to don her bikini while her sister went outside and set up the chaise longue chairs. When Dina finally appeared her sister asked her to place suntan lotion on her back and Dina's nipples grew hard and she felt the heat begin to gather in her tiny bottoms as she ran her oiled hands over the naked expanse of her sister's back.

Dina had to stifle a moan of pleasure when Dani applied oil to her back. They then lay face down on the toweled covers lounges and unfastened their tops to eliminate tan lines and chatted.

"I wonder how poor Barry Ingram is surviving without you?" Dina asked her sister.

"What did you hear?" Dani asked turning her head so she could face her sister. "Barry never got anything more than a brief kiss from me and that wasn't anything to write home about."

"What about you? How are you holding up since Chad Michaels moved away?" Dani continued and enjoying the stunned look on her sister's face.

"You knew?" Dina asked.

"Yes. He told Mark Williams, who told me," Dani replied.

"We only did it twice and it wasn't all that great so I don't miss it and doing all right without it," Dina answered as she stared into her sister's eyes.

"You've found someone new, didn't you? Please tell me," Dani begged.

"I didn't find anyone," Dina said firmly.

"So you survive masturbation as I do? Who is it you're with?" Dani begged again.

"Please leave it alone," Dina replied and her sister let the questioning stop.

Eventually, Dani fell asleep in the warm sunlight and Dina was able to take in the sight of her sister's firm bottom under her tiny bikini bottom. That combined with the sight of her long and shapely legs glistening with suntan oil had Dina dripping with desire and she needed release.

Her Mom's office was in the front of the house so there was no chance of looking out the window and wondering what her daughter was doing. Dad was in the garage involved in finishing another project and his concentration was on what he was doing, it was risky but worth it.

Dina allowed one hand to slide under her and locate the waistband of her bikini where they slipped under it, a second later her fingers entered her already wet slit. She stared at her sister's butt and leg as she rubbed her clit, she wanted to reach out and stroke the naked back but that might have awakened her.

Just as her orgasm approached her sister turned her head and stared at her.

"OMG, you're masturbating out here?" Dani struggled to keep her voice low.

Dina's response was a nod of her head and a small moan as her orgasm arrived. When it ebbed she looked into her sister's eyes.

"Who were you with?" Dani asked.

"I was with you," she answered without thinking.

"Me?" came the shocked response from Dani.

"Yes. You get me hotter and wetter than any boy at high school ever could," she responded truthfully.

"Do you do it when I crash in your bed?" Dani asked.

"Every time," came the truthful response.

Dani jumped up and held her unfastened bikini top to her chest and ran into the house.

"Well so much for the truth setting you free," she said to herself.

Dani didn't come down to dinner, telling her parents that she tired and wanted to sleep. Dina was miserable throughout dinner and the rest of the evening. At eleven, her folks headed to bed and Dina to her room where she wept at what she had done. This would mean the end of Dani crashing in her room and that knowledge made her very sad. It was about half an hour later that there was gentle tapping at her door, it was Dani asking if she could come it and talk.

As she stepped into the bedroom, Dina's eyes went wide at the sight of her sister. She was in full makeup and her long blonde hair had been pulled back into a ponytail. She looked as though she was going on a date. Once inside, she closed the door and then untied her silky dressing robe and allowed it to fall to the floor and Dina couldn't believe her eyes.

Dani was dressed in the most exotic lingerie she had ever seen. Dani's bra was made of shiny black silk and the cups were cut low to reveal more of her luscious breasts. A matching garter belt was holding up a pair of seamed nylons, Dina didn't know that Dani owned such items. Dani did a pirouette to reveal that her tiny matching panties were a thong.

Dina was speechless as Dani approached the bed and then flipped back the covers and top sheet so she could slide in next to her sister. Once under the covers, she turned towards her sister and then placed her cherry red lips on Dina's and proceeded to give her a deep passionate tongue kiss. When the kiss ended, Dani pulled away and stared into Dina's liquid eyes.

"And here I thought it was just me with these feelings," she said softly.

Dina reached around her sister and unfastened her bra to reveal a set of perfect breasts. Dani then helped her sister remove her t-shirt took a moment to admire Dina's perky breasts before she slid in closer and mashed her breasts into hers. Once again their lips locked on each other and the girls enjoyed the sensation of the silky soft orbs pressed into them until the kiss ended.

"On those nights when I crashed in your room, I usually masturbated once you fell asleep," Dani admitted in a soft voice.

Dina still had not spoken and tears filled her eyes as she looked at her sister.

"Why are you crying?" Dani asked in a concerned tone.

"Because I'm so happy. I thought you were angry at my confession based on the way you ran into the house," Dina managed to say between her tears.

"I wasn't angry, just relieved. I thought I was alone with these feelings and desires and I didn't want you to see my tears of joy," Dani answered.

"I never knew you owned such an outfit," Dina responded as she ran her fingertips across the front of Dani's silky garter belt and down to the crotch of her panties.

"No one knew about it. I purchased it last Christmas on a whim cause it turned me on when I saw it. I've kept it hidden as our parents would freak out if they saw it," Dani stated and felt herself growing hot at her sister's touch.

Dina gently pushed her sister on her back and slowly began to slide her panties down. She was amazed that her sister's crotch was bare and she began to plant kisses on Dani's lower abdomen. Dani's response was a tiny moan.

Dani gently pushed Dina's head away and pushed her on her back where she drew down her panties, Dina sported a landing strip of pubic hair. A second later she placed herself between Dina's legs and pressed her naked pussy to her sisters where she began to slide up and down across Dina's nether lips.

The girls kissed each other's lips, neck, and ears. They kissed and licked each other's firm breasts and sucked on the extended nipples as Dani's continued her slide. Finally, Dina felt her orgasm approach and she struggled to keep her moans and voice low.

"Dani, I'm gonna cum," she repeated.

"Then cum for me baby sister," she crooned.

The sight and sound of Dina's approaching orgasm sent Dani over the edge as well. Dina grabbed the small pillow and both girls moaned into it as their orgasm arrived. Afterward, they laid there holding each other while planting gentle kisses on each other's faces.

"Tomorrow I will help you removed the last of your fuzz," Dani responded as she gently trailed her finger over her sister's pussy.

"Oh yes," was all Dina could say as she shivered at Dani's touch.

"I wish I had an outfit like yours, it makes you look so sexy," Dina admitted.

"I'll let you wear it tomorrow and when this quartine ends we will get you one of your own," Dani said in a soft voice.

A minute or two later Dina pushed Dani on her back and placed herself between her sister's nylon covered legs and began the same gentle slide her sister had used on her. They had been concerned about how long this quartine was going to last and when they could go back to school and see their friends. Now they no longer cared.
