"May I kiss your butt?" her mother asked.

Joyce dipped more moisture from her daughter's vagina and thumbed her clit, stroking quickly round and round the erect pink node, rubbing over and under her clit hood. The lusty female odor of Bernie's arousal tickled her nose. Joyce's own breathing deepened and quickened as she masturbated her daughter, and she felt wetness between her own labia.

Bernie was sighing and moving her hips as her mother aroused her closer to climax.

"Mom, I'm getting close, put your arm between my legs."

Joyce wiped her wet fingers on Bernie's inner thighs and reached between her daughter's legs to grasp the edge of the dressing table. She angled her arm so her daughter's mound and vulva pressed against her forearm.

Bernie ground her pussy down with her legs together, her favorite masturbation position. But instead of a pillow, her labia were rubbing up against her mother's forearm. She sighed aloud with pleasure.

Joyce gazed at her daughter and smiled. Her daughter looked so luscious, so abandoned to pleasure riding her arm. Even the Greek knot holding her dark wavy hair suggested a Maenad, a wild-woman. She noticed Bernie's anus wink and remembered her daughter's story of her recent anal-erotic explorations with her cousin Ben, including her first penis-in-anus intercourse. She was proud of how open her daughter was to sexual exploration -- group masturbation, boys, girls, oral, anal -- and how much pleasure she found in her body, even if she wasn't confident in her own beauty.

"Mom I'm close," Bernie said. She ground her wet pussy rhythmically into Joyce's stiffened arm. "Put your finger up my butt, Mom."

Joyce enjoyed giving her daughter anal stimulation when they masturbated together. But today she had an impulse to do something she had only tried a few times, and never with her daughter.

"Of course, darling," Joyce said. She leaned forward, lowering her head toward her daughter's broad buttocks. "May I kiss it first, Naomi?" she asked, using her daughter's given name.

"Really, Mom?" Bernie giggled nervously. "Sure, I guess...ooh!!"

As soon as Bernie said, "Sure," Joyce's lips were on her anus. Joyce kissed, then circled her tongue tip around the smoothly crinkled ring. Fresh from the shower, her daughter's butthole tasted faintly of Dr. Bronner's lavender soap.

Bernie whimpered, her senses overloaded. The unusual tickling sensation on her anus played against the erotic pulse from her swollen, highly stimulated labia grinding against firm, moist skin. Her hips shivered uncontrollably, adding to the overwhelming feelings.

Joyce paused for a moment to check in. "How does that feel, darling?"

"I-I like it but oooh, it tickles!" Bernie reported.

Joyce indulged herself in the double taboo a moment more, licking her daughter's anus firmly and feeling Bernie tremble helplessly under her tongue. Finally she decided to spare her daughter any more of the tickling ****. Joyce raised her head. Her pinkie finger, already oiled, pressed at Bernie's anal opening and entered easily. Joyce's finger played a quick in-and-out motion in her daughter's anus, giving Bernie the familiar sensation she craved.

"Yes, Mom, yes, yes, yes!" Bernie chanted as she ground her pussy into her mother's forearm. Joyce's oiled finger rapidly stroked in and out of her butt. "Mmmmmmm....." Bernie's sigh rapidly rose into a cry of orgasm as her clitoris finally reached critical, firing hot, vibrating pulses of energy from the base of her torso throughout her body. She ground down hard into the firm-yielding limb clutched between her legs. Her head tossed up and down, and her cheeks flushed hot and red as she came, and came, and came.

When Bernie had gone from quivering to limp, Joyce helped her daughter straighten up and eased her over to lie on Joyce's large bed. Joyce herself was highly aroused and craving an orgasm. Sometimes she and her daughter would help each other masturbate, but she wasn't sure if she was patient enough to wait for Bernie's help.
