It was the moaning that led her through the house.
Clearly Diane's daughter thought she was alone. It's not that Jennifer was altogether loud, though the tenor of her gasps indicated comfortability with her surroundings. But the urgency and the intensity of the noises Diane's daughter awakened an unholy interest.
Perhaps Jennifer hadn't had time to touch herself in a while. The 21 year old beauty was finishing her senior year of college at her nearby alma mater. Yale University, at a breakneck pace. Diane remembered her only child was scheduled to finish her last final earlier that morning.
Perhaps this was a celebration of sorts. As Diane quietly made her way through her family's home, she wondered if Jennifer was rewarding herself for her straight A's. Walking past her daughters empty room only to hear the sounds increase made Diane stop dead in her tracks.
"That little slut is on our bed," she whispered to herself.
Most people probably would have backed out of the house when happening upon this awkward situation. From the start Diane's interest was peaked. At first she just wanted a glance at her daughter, a chance to see what had Jenny so riled up.
But Jenny was on their bed. And that changed everything.
Long before Diane was married and Jenny was born, the 45 year old personal trainer had an unhealthy obsession with scores of porn and sexy stories. She read and watched ad nauseam. Diane used porn and sites like Literotica to keep from indulging in some of her darker desires. Instead she saved up as much as she could of her proclivities for her future husband.
When Diane met Nick she wasn't quite a virgin, but she released all her inhibitions. They spent all 24 years of their marriage toying with the boundaries of sex within the confines of marriage. But that couldn't quiet her deepest desires.
Knowing her daughter was slutty enough to rub her cunny on her own parents bed awakened the beast in Diane. She never looked twice at her daughter before; Diane's biggest search subject for sex stories and porn had always been just that, a subject. She never thought there was anything real there. Jennifer's moans were making decades of secret clit rubbing fantasies all too real. Long before Diane's brain realized it her body made the choice.
As Diane slowly crept into her own doorway she paused to survey her daughter. Her mouth watered as she watched Jennifer, oblivious to world eyes glued to the flat screen protruding from the amour at the foot of their California King Bed. Her husband had affixed their enormous contraption with wireless headphones so the spouses could watch TV without disturbing each other's slumber.
Of course a more devious use had come to Diane's mind as her husband explained the new feature. And with the sounds blocking out all distractions you could really become blindly absorbed in your viewing pleasure. Diane briefly recalled the blissful afternoon when her husband caught her luxuriating in the surround sound of some poor little typical pig tailed girl caught alone in the family barn. It was hard to remember which was better: the orgasm she had as her husband walked in or the one she had as he spanked her for being such a wanton whore right after.
All that occurred in a smaller part of Diane's consciousness. The rest was solely devoted to formulating a plan for writhing body before her. Jenny's fingers were fast rubbing her little clit, something she'd been hard at work at for some time, as evident by the sloppy wet sound her tiny little pussy made as she stroked it earnestly.
Jennifer's perfect 21 year old body was due to good genes and Diane's demand for the family to dedicate their bodies to fitness. Jennifer's years of ballet and flag football had toned her legs long before she entered college. Thanks to her mother's credo and an addiction to Pilates Jennifer was able to keep her figure throughout the stress of 4 years of college exams. There was a softness to Jennifer's long legs now though, a natural speeding of her thick thighs that came from a healthy diet and what Diane had long suspected-sex.
Jennifer's breasts filled out during her sophomore year. The late bloomer grew to a sexy 38 C, which she normally accented with push-up bras and fitted shirts. At this moment Jenny's perfectly tanned tits were bouncing freely thanks to her ministrations. Her dark nipples were hard, causing Diane's mouth to water. Always preaching body confidence, Diane had always demanded Jennifer he light her high round ass as well.
At the current moment Jennifer's enviable figure was jostling around Diane's satin topped comforter leaking pussy juice onto the cover. Diane had to start moving before Jennifer noticed her mother's presence or this would never work. Jennifer was too busy shutting her bright blue eyes and shaking her long dark hair back and forth in the throes of pleasure to see Diane slink to her dresser and slip out a red bikini.
