Chapter 5

Still clutching her thin robe to her aroused body, Diana tried to move away from the window into the girls' bedroom, but she couldn't. Paula's and Kate's sexual play fascinated her, drawing her eyes as the light of a candle draws a moth.

This uninhibited lovemaking between stepsisters was something new; something that incited strange, previously unfelt desires within her. As she watched them embrace and caress on the bed, she could feel their young, exploring hands on her body and wished that the sensations that coursed through her were more than just mental. She wanted to be in the room with them; wanted to feel their mouths and hands and bodies pressed against her.

Paula, removing Kate's arms from around her nakedness, suddenly rose from the bed and held her hand out to her sister. The dark-haired, younger girl smiled, obvious excitement in her dark eyes, and bounced up, taking the blonde's hand. The older girl leaned forward and gently kissed her companion's lips, then led her before the window.

Together they stared at Diana!

She had been discovered!

Diana's heart missed several beats. No better than a common window peeker, the two girls had found her gazing in on their sexual pastimes. She felt a hot, embarrassed heat flush through her body.

No! They didn't see her! she suddenly realized. The two teen-age girls had not found her out. They were staring straight at her, but they didn't see her. Relief flooded her body and at the same time, her mind reeled with confusion. How could they not see me?

Then it dawned on her.

The alcove, the chairs, the curtained window--all of it made sense. The window wasn't a window at all, but one of those one- way mirrors which allow persons behind them to see out, but persons on the other side see nothing but a silver surfaced mirror. And the alcove and the chairs were nothing more than a small viewing area for spectators to gaze upon the activities in the bedroom. Sexual activities, she assumed.

Another of the mansion's "quirks," she grinned to herself, as she wondered how many guests to the Hightower estate had been placed in this bedroom. And even more interesting were the possibilities of who used the alcove. The lack of dust she had previously detected and the electric lights that hung from the ceiling pointed to the fact that the alcove with its special "Window" were used. Was this the strangeness of the Hightower family that Michael had tried to warn her of? Was this viewing area here when the Hightowers bought the mansion? Or was it an addition that the elder Hightower had dreamed up? The whole implications of this voyeuristic haven fascinated her.

But even more fascinating was the activity of the two girls on the other side of the one-way mirror. Now secure in her position, Diana watched, feeling the wanton throbs of lust rising in her again.

Paula now stood behind her sister. Both girls gazed into the mirrored side of the glass, smiling and unaware of their new sister-in-law who watched their every move.

For a few brief seconds, the older girl was busy behind the dark-haired girl, then Kate's bra came free, falling away from her body. Diana found herself gasping with excitement as she stared at the young girl's exposed tits. Still developing, the young breasts were perfect cones, white, soft and smooth and topped by dark mushrooms; nipples that were stiff and erect from the sexual play she had so vigorously taken part in.

Unseen hands suddenly began to move the girl's briefs down the rounded curves of her hips, as Paula worked at the panties from behind. The light cloth panties dropped around the girl's ankles and she stepped free, gazing at her nakedness in the mirror, as did Paula. And as did Diana from the other side of the mirror.

The older girl's arms slid around her partner's midriff and pulled the girl back to her. Taunting with her lips and tongue, the blonde slowly and tantalizingly kissed her way up her stepsisters shoulder. Her teeth joined in as she reached the younger girl's neck, teasing her way to the sensitive lobe of her ear. As she tongued and kissed at Kate's neck and ear from behind, Paula's hands eased their way up from her waist and cupped gently beneath Kate's cone-shaped breasts.

Both the girls' eyes once more turned to the mirror as they watched Paula fondle and taunt the beautifully matched tits she possessed.

Lightly, with a show of knowledge that spoke of several similar experiences, her fingers lightly brushed and caressed the young cones. Over and around the sleek whiteness of the breasts, her fingertips swirled in exciting little circles. Spiralling upwards, her hands rose, until at last the tips of her fingers nudged at the aroused dark buds of Kate's nipples.

Diana could see the younger girl gasp with rising desire under the expert manipulations of her stepsister. Kate's dark eyes fluttered, doing their best to remain open and view the titillating scene of her body being caressed, but the sensations Paula ignited in her body were stronger, eventually winning out, and the younger girl closed her eyes, losing herself amid the pleasure that flowed through her tits.

The blonde beauty suddenly stepped in front of the girl she fondled and dipped her mouth to the breasts she handled with loving care. Her cheeks hollowed deeply as she sucked up one of the dark cherries of flesh atop one of the cones. The younger girl trembled, her hands reaching out and squeezing brutally into the tits of her companion. Neither of the girls seemed to mind in the least.

Moving her mouth to the opposite knoll of breast, Paula's tongue, wet and pink, flicked out from behind her lips and lashed back and forth across the new nipple it found. Vigorously, she worked her oral digit until the black-haired girl moaned for her to stop. When she did, she opened her mouth and stuffed as much of the titflesh as she could into her. She ate, contented with the silken textured cushion of flesh her mouth had found. She sucked and nibbled, her tongue laving its way over the hard button of nipple their passion had created.

Her hands moving to Kate's shoulders, Paula slowly edged the younger girl back toward their bed, while her mouth continued to excite fresh thrills through the enticing young body. Automatically, the black-haired girl sat on the bed, jerking her reddening breast from her companion's eager mouth. She smiled, then lay back, spreading her thighs wide, presenting an unobstructed path to the plump little mound of her sex and the black pubic moss that was bushed over it.

Paula dropped to her knees and leaned forward. Her lips lightly kissed the dark triangle of shiny fur covering her sister's snatch, eliciting quivery little trembles from her partner. Then her tongue once more darted out and weaved through the forest of pubic down, tickling and teasing around the already wet cleft of Kate's sexual lips, but never dipping into the hot hole of her young cunt.

Easing back just a little, the blonde-headed girl moved her hand between her sister's thighs, spreading the lips of her pussy so that she could see the extended bud of the girl's clit and the scalloped inner lips of her labia. Again, her head ducked downward. Her tongue flicked out and ran up and down the pink slash of the girl's sex.

Expertly, her tongue tip dipped lightly into the musky cleft, tapping and twirling out its exciting dance of pleasure. The girl above her moaned and reached down, grabbing her head. She resisted the urgent fingers that pushed her face forward, delighting in the effect her tauntings had produced. Up and down the pink slit of Kate's opened pussy she teased and aroused.

Then her tongue skipped upward, gently caressing the nubbin of ecstasy. She tenderly kissed the super-sensitive clit, hearing the moans of approval that came from above her. She licked and carefully lapped at the enticing button, twirling her tongue around its tiny circumference. Her lips closed around the bud of sensation and she sucked at it as a woman might suck at the cock of a man.

The black-headed beauty, half on and half off the bed, writhed as her lovely companion unlocked thrill after excited thrill in her body. She begged and moaned. Her hands pulled at the blonde head that taunted and played with her growing arousal. Her satisfied groans filled the spacious bedroom as the titillating oral digit slipped from her clit and entered the heated channel of her cunt.

Paula's entry into her sister was far from gentle. It was quick and hard, spearing as deep as she could into the honey- filled socket, burying her face in the wetness of the girl's vagina. In and out, she probed in her penis-imitating oral style. She licked and lapped, eating her stepsister with unrestrained relish.

Soft and smooth, like oiled silk, her tongue moved around within the humid interior of the girl's cunt She sucked deeply, swallowing the thick sexual juices she drained from the quivering channel, then drilled her tongue back into the enticing folds of Kate's pussy.

Around and around, her inciting oral digit twisted its pleasure as Kate's hands pushed her face into the mouth of her belly. The younger girl writhed and quivered on the bed as her passion rose to a consuming fever of lust. She groaned as she felt the delightful tongue once more change its tactics, pumping in and out of her vagina. Her own pelvis began to move, undulating with the rhythm of the mouth that ate at her.

Suddenly, there was a finger on her clit, rolling and fondling the aroused button. The dual stimulation rocked her with lusted madness. Body jolt after body jolt sizzled through her over and over as the waves that throbbed in her thighs expanded, blasting outward.

In and out, the blonde's tongue drilled, spearing to its limits within her. Faster and faster, her oral probe reamed around in the humid softness of her cunt. Around and around, the fondling finger rolled her clit.

She groaned and moaned as she rose on the skyrocket of ecstasy. Her thighs exploded and pleasure raced through her body. Crying out in desire, she pushed desperately at the head working so wonderfully at her sex, then abruptly released her hold, giving way to the sweetness of oblivion.

Giving her sister's throbbing cunt one last hasty kiss, Paula rose. She smiled down on the younger girl who writhed and moaned on the bed, then stepped across the room to a chest of drawers.

Diana gasped once again as she saw what the older girl extracted from the top drawer of the chest. She had seen them before, in the men's magazines Michael brought home, and had occasionally sneaked peeks at them amid the glass cases of adult book stores they had gone to. They carried the sterile name of "marital aid" on all the advertising she had seen. Commonly they were called dildoes. And the one Paula was now strapping around her waist was at least seven inches long, and an inch thick. It was hard looking and complete with a red rubber head and rubber balls dangling beneath.

Smiling lewdly to herself, the blonde-haired beauty stepped back to the bed and eased her sister's thighs open. She grasped the imitation cock with one hand and stepped between the inviting "Y" opened before her. Carefully guiding her rubberized manhood into the target she sought, her hips jerking forward and burying most of the thick hose into her stepsister's cunt.

Still lost in the waves of pleasure that swirled through her body, the sudden plunging entrance of the dildo jolted Kate. Her body twitched and her eyes jerked open with surprise. A startled "Ahhhhhh!" was wrenched from her lips. Then she relaxed and gazed lovingly up to the older girl standing above her.

Leaning over the black-haired girl, Paula stretched her arms out and planted them to either side of her sister's head so that they supported the weight of her body. She lowered herself once, so that their lips met briefly. Kate's hands reached up and once more busied themselves with the elongated cones of titflesh that now dangled sleekly from Paula's chest. The older girl moaned and her pelvis hunched forward slamming about an inch of the dildo into her companion's pussy.

Raising her legs and resting her feet on the side of the bed, Kate opened the angle of entry into her body. She moaned as the thickness slid deeper into her. It filled her with its hardness, stuffing her cunt to the brim.

Paula edged back, glancing down to watch the imitation prick she wore glide from the snatch it had impaled. Long and slick with young womanly lubricants, it came out. She paused only when the knob-like head of the device was still buried within the hole she was now fucking. Then, slowly this time, her hips inched forward, drilling the rubbery hardness into her sister.

The younger girl groaned as she accepted the substitute manhood that skewered her body. Her hands squeezed and kneaded their approval into the firm cones of tit she held. Her own pelvis arched slightly to help take in the thickness that slithered into her belly.

Grinning with delight at the pleasure she fed inch by inch into the girl, Paula eased her hips outward once again, then moved them forward. Pleased with her role of a man-made man, her pelvis took up a steady in and out rhythm, a rhythm which Kate's hips matched stroke for stroke, welcoming the invading length of dildo that reamed into the depths of her quick.

Lovers once again, the two teen-age girls lost themselves in their lovemaking. Kate groaned and moaned as her body was filled and packed with artificial cock. And Paula reveled in the sensations she ignited in her stepsisters body.

A movement to one side of the room diverted Diana's gaze from the two young girls. The overly large brass knob to the door moved and the heavy wooden portal inched into the bedroom. A boyish face, surrounded by a reddish-blonde mop of shaggy hair, poked inquiringly inside--Bryan!

The youth's eyes widened to saucers as his gaze moved around the room, alighting on his two sisters so obviously involved in themselves and the pleasure of their youthful bodies. The surprised expression quickly faded from his face and was replaced by one of pleased amusement. He edged inside the bedroom and stood silently watching the feminine couple, completely unnoticed by either Kate or Paula.

Perplexed and somewhat annoyed by the boy's presence and possible interruption of her private session of voyeurism, Diana intently eyed the intruder from behind the security of the one-way mirror, hoping he would leave as quietly as he had made his rude entrance into the room. But he didn't. Bryan just stood there, grinning from ear to ear as he gazed at the alluring, writhing bodies so lustfully joined on the bed.

Diana detected a definite increase in the labored rise and fall of the youth's muscular chest, which strained at the white fabric of his T-shirt as he sucked in his breath in deep gulps of arousal. But more notable was the growing bulge that filled the crotch of his jeans. There was no denying the testimony of his body. Bryan was every bit as affected by the stepsisters' carnal activities as she was.

In a quick flurry of eager young arms, the boy reached down and grabbed the bottom of his T-shirt and hastily wrenched it up and over his head. As he pulled the white cotton shirt off his arms and tossed it atop the chest of drawers, Diana found herself gasping out loud to herself once again. Not the knotty, thick muscles of a football player or a weight lifter, but the long, graceful muscles of a young swimmer covered his body. She shivered as she watched the rippling strength that corded senuously beneath the golden browness of his suntanned skin.

Kicking his loafers free from his feet, the youth's fingers dropped to the front of his jeans and made short work of the series of awkward buttons running down his fly, then skinned the denim pants down his legs. His thighs and calves and tight- looking ass were a perfect match for his athletic physique.

And if there had been any doubt that Bryan was a young man, rather than a boy, it was quickly dismissed from Diana's mind, as his hands jerked his net-webbed briefs downward, revealing the rigid lance of his manhood that stood thickly from a forest of flaming red hairs covering his groin. His peeping-tomasita sister-in-law clutched her thin robe closer around her body, as she viewed the full size of his solid, pulsing cock.

Suddenly Diana's whole body quaked with flaring arousal as the youth's intent pushed its way through her lust clouded mind. He was going to join his sisters entangled so wantonly on the bed!

Stepping quickly to the same chest of drawers Paula had gone to for the dildo that was now strapped to her waist and reaming the tender, young pussy of her stepsister, Bryan retrieved a blue jar of petroleum jelly from that same top drawer. Dipping two fingers into the jar, he extracted a thick glob of the heavy lubricant and smeared it over the jerking thickness of his prick, until it glistened beneath the room's overhead light. Smiling down at his handy work, he recapped the jar and replaced it in the drawer.

He moved barefoot across the room, stopping but a foot behind his own sister. Gazing down, he watched the rhythmic undulation of the girls' lovely young bodies, as they continued their lovemaking still completely unaware of the masculine eyes that watched from behind.

Then he stepped forward, abruptly wrapping bit arms around his blonde-haired sister's slim shapely waist, pressing his body firmly against her in a strong hug. The young girl's hips abruptly ceased their steady in-out motion and she jerked upright, slamming the full length of the dildo around her waist into the vulnerable cunt of the dark-headed beauty beneath her. Both the girls, surprised for their own separate reasons, looked around in confusion and in shock from the separate sudden intrusions.
