It was Friday evening, and Kate was settling into bed for the night. Both of her daughters were out with dates, and she had the house to herself. Kristina, her oldest, was at a concert her boyfriend's band was playing, and Zoey was celebrating her eighteenth birthday with friends at her boyfriend's apartment. It was still early, but Kate was looking forward to spending a quiet evening by herself in bed.
She climbed under the covers, and reached for her bedside drawer, pulling out a small yellow vibrator. It seemed like it had been a long time since she had had the opportunity to pleasure herself, and she had every intention of taking advantage of her alone time.
When the girls' father left them four years earlier, Kate began to discover her sexuality, and quickly realized she was a lesbian. Thinking back, she knew it was part of the reason things didn't work with her husband. From the moment she outed herself to her daughters, they'd been nothing but supportive, and she loved them dearly for it.
It had been months since Kate's last sexual encounter. Lately, her fantasies had been growing more and more perverse as her lack of sexual contact left her constantly horny. She found herself growing attracted to her own daughters, and picturing their naked bodies during her frequent masturbation sessions. For the past week or so, she couldn't stop imagining the two young beauties making passionate, incestuous love to each other. At first the fantasies disturbed her, but now, she relished them, convincing herself they were just harmless thoughts she had in the privacy of her own imagination.
And so, she settled into bed, her vibe between her legs, and started to picture Zoey and Kristina, tentatively kissing in the older girl's bed. Her pussy was quickly moistening, and she pushed her panties aside, rubbing her toy against her slick vaginal lips.
Just then, a light knock at her door surprised her, and she snapped back to reality.
"Mom?" a soft voice called from the hallway. "Are you still up?"
"Y-yes, Sweetie. Come on in!" Kate called, stashing her vibrator under her pillow and re-arranging herself under the covers.
The door creaked open, and her oldest daughter, Kris, came into the room. Her eyes were red and puffy - she had obviously been crying.
"Oh, Honey! What's the matter?" Kate cried.
Kris crawled into bed next to her mother, and Kate wrapped her arms around her sniffling daughter.
"Men are jerks, Mom. Tyler was supposed to wait for me after his set, but he fucked off with the band and left me stranded backstage! I had to call Nicole to come get me, because he wouldn't answer his cell!"
"Oh, Sweetie! I'm so sorry!" Kate said, hugging her closer.
"It's okay, Mom. Don't be. It's Tyler who should be fucking sorry! I should just dump his ass and swear off men for good!"
"Well, that worked out for me, Hon. Maybe you should!"
Kris looked up at her mother and they both burst into laughter. Kris snuggled into Kate's chest, smelling her soap on her neck and shoulders.
"Thanks, Mom. You always know how to make me feel better."
"Anything I can do to help, Hon." Kate replied. She started to caress her daughter's arm as she spoke: "Although, I was serious. Maybe you should swear off men, and try being with a girl."
Kris lifted her head again, looking quizzically at her mom.
"I dunno, Mom... I've never felt any desire to be with another girl before."
"Well, neither did I really, Sweetie. Not until your father left."
Kris thought about it for a few seconds. She quickly realized she found the idea of being with another woman surprisingly appealing
"Well... I guess it might be... nice... But... I wouldn't even know how to approach a girl. I mean, who could I even trust to keep something like that quiet?"
"Hmm... I guess you don't want to be outed before you're even sure of what you want... That's for sure..." Kate said thoughtfully. Inside, her mind was reeling at how quickly the conversation had turned in this perversely enticing direction. Despite her better judgement, her kinky desires drove her to test the waters.
"I mean... the only girl I can think of that would keep a secret like that for you would be... well, your sister, right?"
"Yeah, Zoey would definitely keep any secret I asked her to, but I mean, I can't exactly try doing... that... with her."
"Why not, Sweetie?" Kate asked. Her hand had slid from Kris's arm and was now resting on the girl's stomach.
"Well, because that's incest..."
"Oh, Sweetie. I don't think you need to worry about that! Incest is only bad if you're going to get pregnant! And you can't get pregnant with your sister, right?" Kate started to rub Kris's stomach gently as she spoke.
"Well... no... I guess I can't..."
"I mean... if you really think about it... it would be the safest sex you could have!"
"Haha... I guess in a weird way that's kind of true. It would be too weird, though." Kris replied, hesitantly.
"Oh, I don't know, Sweetie. Your sister is beautiful, after all, don't you think?" Kate's caressing hand was now grazing the hem of her daughter's shorts.
"Well, yeah. She's very beautiful..." Kris agreed quietly.
"So, try this, Hon. Close your eyes."
Kris closed them.
"Now, picture what it would be like to kiss her. Imagine you're alone in your room, and the two of you are on your bed. And she leans in, and you're kissing. Does that feel weird?"
Kris licked her lips. She didn't say anything, but shook her head no.
"Now, imagine she reaches up and touches your breasts." As Kate spoke, she gently unbuttoned Kris's shorts. "Now imagine you reach up to cup hers."
Kris seemed lost in the fantasy. She didn't even react when her mother's hand slipped into her panties.
"Imagine you're both naked, and touching each other. How does that make you feel, Baby?" Kate's hand was now gently stroking her daughter's wet slit.
"I-it feels good!" Kris stammered. Her brow was beginning to shine with sweat, and she was unconsciously working her hips against her mother's rubbing fingers.
"What do you want to do to her, Hon?" Kate asked.
"I... I want to l-lick her pussy!" Kris blurted. Kate smiled devilishly at her daughter's admission.
"Then do it, Sweetie. Lay your sister down, crawl between her legs, and lick her pussy."
Kate's fingers moved faster in her daughter's slick pussy as she encouraged her fantasy. Kris was overcome with desire, her body writhing against her mother's as she imagined fucking her little sister. The fantasy combined with the feeling of her mother's hand proved too much for the sensitive girl, and she moaned loudly as an orgasm washed over her.
Kate continued to gently masturbate her daughter through her orgasm. Her own pussy was on fire, but she forgot about her own pleasure for now, entirely focused on carrying Kris through her climax. When her writhing finally started to calm, Kate lowered to girl to her pillow, slipping her hand gently from between her sticky thighs.
"Oh... Mom.. that was so nice..." Kris whispered tiredly. She seemed to pass out almost immediately, suddenly overcome with exhaustion. As she drifted to sleep, Kate heard the front door slam. She slid from her bed, leaving Kris to rest, and went to investigate.
Kate stepped out of her room just in time to see Zoey's door slam shut. She sighed, glancing back towards her bed to ensure Kris was still asleep. Satisfied her daughter hadn't been disturbed, she approached Zoey's door. She could hear her youngest sobbing in her room, and knocked softly.
"Zoey?" she called. "Are you alright, Sweetie?"
