The girls helped clear the kitchen, Katie ditching her sandals to patter about barefooted, Lilian rolling up her sleeves and undoing a couple buttons at her throat. The three women chatted about the day, recounting their various conversations with guests.
After the last guests were escorted to their vehicle and waved off Lilian's dad came to collect his wife, kissing both girls goodnight. The dishes were finished in silence, then Katie excused herself. Lilian put away the last of the dishes and poured herself another whiskey. She turned out most of the lights, sitting on the couch in the dim light to sip her drink and relax.
The quiet click of a door latch woke Lilian, who had dozed briefly on the couch. Leaning forward she finished her drink and set her glass on the coffee table then leaned back into the couch. She looked up when Katie turned the corner, still in her dinner dress but without the jewelry, still barefoot.
Neither woman spoke, words were useless. Katie tipped her head as she slowly crossed the room, watching Lilian. Lilian stared back, wary, aroused, buzzed. Katie hesitated when she came up to Lilian, her front teeth digging into the softness of her bottom lip as she watched her step-sister. Lilian didn't move except to steady Katie when she slowly but gracefully straddled Lilian's lap. Katie slid until she was almost too close to Lilian, bending down to offer a kiss.
Lilian let Katie kiss her, her mind too far gone to think about possible consequences, if this was a good idea or not. She responded intermittently to her step-sister's advance, keeping the kissing almost chaste, even when one of Katie's hands stroked the length of Lilian's torso. Lilian looked up when Katie retreated, seeing the same hunger in those impressive eyes. They mirrored the way she felt, so Lilian raised a hand and gently guided Katie in for another, deeper kiss, her fingers tunneling into the thick wealth of honey gold hair.
Katie moaned so quietly it was little more than a vibration shared between their lips. She began a slow rolling motion with her hips, pressing gently into Lilian. The slight pressure fed Lilian's simmering arousal, the intent behind Katie's movement doing more to excite Lilian than the actual grinding. She set her free hand on her step-sister's hip, feeling the soft dress and the flexing muscles beneath. She held Katie as they kissed, exploring each other's mouths, with the occasional kiss to cheeks and foreheads.
Katie's hands weren't still, exploring Lilian's chest and shoulders. It wasn't long before she'd unbuttoned Lilian's vest and started in on the buttons of the dress shirt. Lilian brought her hands up from Katie's hips and cupped her cheeks, breaking their kiss. "No."
That single word stopped Katie, brought her rhythmic grind to a shuddering halt. Lilian felt Katie's fingers twitch against her belly, felt the heat radiating from between her step-sister's thighs. Looking up through her eyelashes Lilian saw the confusion battle with need, then turn to mild panic. Understanding that Katie was jumping to the wrong conclusion, Lilian let one hand drop, brushing her fingers against the softness of Katie's dress. "Show me."
Delicate gold eyelashes tinted with mascara fluttered shut. Katie leaned away, one hand on Lilian's knee for support as Katie resumed her hip shimmying, her other hand slowly bunching the material of her dress to teasingly expose herself for Lilian. Lilian watched, her pulse quickening as a lacy thong was revealed. The white against Katie's tanned skin had Lilian's mouth watering, as did the obvious moisture soaking the gusset. She couldn't resist and stroked the lacy front of Katie's thong, brushing her fingers against it as she'd done the dress.
Before Lilian could try to remove the panties to peek at what they covered Katie dropped her dress. Still leaning back, she shook her hair back and slid first one strap, then the other off her shoulders. The dress fell, pooling forgotten around Katie's rolling hips. Lilian stared, embarrassed to feel heat burning her cheeks. If Katie noticed, she didn't bring attention to the blush. Instead she reached for Lilian's hands and brought them both to her chest, pressing them into her own breasts.
Lilian cupped them, a purr vibrating quietly in her chest. Katie's breasts were firm, pliable, and round with just a slight pear shape. The nipples crowning each one were a delightful pink, tightened to twin peaks in the cool air. Katie helped Lilian fondle them, silently showing how she needed to be touched. Lilian couldn't help watch Katie's face as they squeezed and stroked together. The open emotions on display were captivating. Leaning in, Lilian pressed a wet kiss to the center bottom of Katie's ribs, the soft inner curves of Katie's breasts pillowing Lilian's forehead briefly. More kisses trailed up the central divide, then veered right, spiraling in to find a softly rigid nipple.
Lilian almost lost herself in the moment, one arm wrapped around Katie to keep her close as Lilian suckled at her left nipple again. The small, tender bud in her mouth and under her tongue, the soft panting of Katie's breath in her hair, the warmth and weight of her in Lilian's lap, even the soft floral notes mixed with the more natural scent of Katie's skin. Fingers tunneling into her hair pulled Lilian back. Katie kissed Lilian again, more passion and need growing between them. Katie caught Lilian's hand and pulled away from the kiss to suck Lilian's fingers, her tongue swirling and stroking the digits individually.
Lilian was too busy watching her step-sister suck her fingers to care that Katie's other hand was sneaking between their bodies. She didn't stop Katie when she cupped Lilian, firmly and boldly rubbing at her pussy. Lilian needed the contact, needed the pressure to send a heady rush of pleasure through her body. When Katie let go of her hand and leaned in for more kisses Lilian met her halfway. She pulled Katie in, hands on Katie's hips to guide the humping into something more. She bucked up into Katie, small movements that forced a gasp from her step-sister's lips.
Katie leaned back sharply, gasping quietly for air, head thrown back as Lilian added more speed and purpose to their grinding. Lilian watched her, more turned on than she could remember being. Katie finally raised her head, brow furrowing. She bared her teeth at Lilian and clutched Lilian's arm, one hand finding purchase in the loose vest. Lilian shook her head, not wanting Katie to cum yet, half amazed she could cum just from making out on a couch. She slid Katie away, taking away their intimate contact.
That didn't sit well with Katie. Lilian didn't expect a furious reaction and was shocked when Katie pushed back, trying to regain the closeness, a hand suddenly around Lilian's throat. Katie didn't squeeze, Lilian wasn't being choked, but she did relax back into the couch in reflex to the threat. Keeping her chin high, Lilian forced Katie's hips to still, her thumbs digging into soft flesh. Glazed over hazel eyes met Lilian's stare. Lilian didn't blink and won the stare down. The frenzied arousal cleared from Katie's eyes and she moved her hand, cupping Lilian's cheek for a soft kiss. "Please." Katie whispered.
More than ready for this to become more, Lilian gathered Katie close, bracing her heels against the couch. She stood, legs only slightly wobbly, and carried Katie to her room. The coo in her ear as they crossed the living room was more than worth it.
Lilian deposited Katie in the desk chair and closed the door, making sure it was locked. Turning to her step-sister Lilian discarded the vest. "Play with yourself. Show me." Lilian undid one more shirt button, watching Katie chew her lip.
Katie caught on quickly, standing and bending over the chair, lifting her skirt up and over one hip. She looked over her shoulder at Lilian, and did a little swaying dance, caressing her own bottom, playfully slapping the smooth cheek. Katie flexed and swayed on her tiptoes, giving Lilian a lovely peekaboo glimpse of a plump pussy under wet white lace, framed between sleek thighs. Katie lifted a leg, braced on the bedside and snuck a hand between her legs. She rubbed her clit, dropping her head at the contact, then let her fingers continue, pressing into the panties, more moisture leaking onto the soaked gusset.
Lip caught between her teeth, Katie repositioned and reached back again, this time to pull the thong aside. Lilian swallowed a sudden surge of saliva at the glistening, plump pink folds of Katie's pussy. Katie watched Lilian with heavy eyes, a single finger tracing up and down her sex. She moaned quietly when she sank that finger to the third knuckle, removing it swiftly and sucking the juice from it. Lilian groaned when Katie slapped her own ass again, fingers immediately returning to circle her clit.
It was hard to stop watching Katie masturbate, but Lilian stood and crossed the room, naked except for a harness buckled to her hips, a generous dildo bobbing. Katie straightened when Lilian approached, those needy eyes widening when they landed on the toy. Katie gave Lilian a look, one that screamed gleeful surrender. Lilian pushed Katie's dress off and kicked it away, then tugged sharply on the thong's waistband. It seemed strong. Katie bent over without any prodding, stepping wide to give Lilian room, arching her back to present her drenched sex.
Taking the thick cock in hand Lilian swiped it's blunt tip up and down through Katie's wetness, then seated the head fully, her hands settling on Katie's hips to control the first few strokes. By the third stroke Katie was whining softly, pushing back to meet Lilian. Any plan or thought to take this slowly was shot to hell when Katie whispered, "Harder. Please. Fuck me harder. Faster." Lilian sank the toy, adjusted her stance and pulled away. She thrust back in hard enough to squeak the desk chair under Katie, fast enough that Katie had to brace her arms to avoid falling.
