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 blackhaired 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.
