Luke sprinted across the floor of the kitchen, laughing aloud as he listened to his giant sister shout after him.
"I can't believe you did that you little bastard!" Margaret cried, hopping up and down on one foot.
"That tack could have really hurt my foot!"
A small blot of blood was visible on the right sole of her white knee-high socks, in the approximate spot where Luke had snuck an upturned tack into her one of her shoes. The sister and tiny younger brother had begun playing pranks on each other with increasing frequency in the past week, and Anne welcomed the constant ruckus; the antics signalled a return to relative normalcy in Luke's behaviour. Despite the unfortunate shrinking circumstances, they had reverted back to their boisterous rivalry; and in her mind that was a wonderful improvement from the bout of depression that had afflicted her poor son since the incident.
Anne sat at the kitchen table as she watched her 4-inch tall son run from the room, and let out of a squeal of delight as Margaret lept up and began to chase after him, her breasts bouncing considerably beneath the white V-neck sweater with checkered skirt she wore today. Anne squeezed her thighs together and her pussy tingled as she imagined what punishment her daughter might have in mind for retaliation. Despite whatever pranks Luke may come up with to annoy his sister, Margaret always caught up with him, and her punishment was always guaranteed to be more extreme in response.
Anne had to admit to herself, the potential new ways that her tiny son could be dominated was becoming a considerable turn on that consumed her thoughts more and more every day. Each night before bedtime in recent weeks, Anne would give Luke a big wet goodnight kiss as he lay on the small pillow on the floor beside her bed (engulfing almost half his body with her plump pink lips in the process), and then she would endure a short but agonising wait to ensure her tiny son was asleep before she moved her soft hands over the beautiful mounds of her enormous motherly breasts, each squeeze sending ripples of goosebumps across her pale flesh. Imagining all the ways in which she could use and abuse her helpless son on the floor right next to her for her pleasure, she would slide her hands down further down, brushing over her not-quite-flat but fairly toned belly, and eventually down to cup her pulsating, swollen pussy. Without fail, she was always soaking through her panties in anticipation at this point, and it didn't take long before she would be plunging her fingers into her steamy quim to the knuckles, producing considerable amounts of sticky white girl-cum in the process. It became a nightly struggle not to scream aloud and thrash about too violently as she came hard, fantasizing about using her son in all kinds of taboo ways.
Every night, she imagined licking his tiny form all over, sucking on his body like a lollipop, and guiding him into the most intimate folds of her body - covering him in her slimy, sticky cum, and making him drink his own mother's juices as she slid and pumped her son's entire shrunken body in and out of her aching pussy with reckless abandon. And then, when he was completely exhausted from being used as her own personal living dildo, her taboos became even more extreme. She imagined pushing him out of her pussy, soaked in her cream, and then squatting above him and as her stomach begins to rumble and her arsehole begins to pucker and quiver...
Anne snapped out of her daydreams, realising that she must have looked quite a sight; sweating profusely in her chair, her eyes closed, cheeks flushed, one finger curled in her mouth as she sucked on it wantonly. Her sizeable bust heaved against the tight sports bra and her meaty, toned, milky white thighs squeezed together, toes curled while her pussy hummed in her skin-tight yoga shorts. She was suddenly filled with a wave of shame and guilt - the same kind that often plagued her immediately after her taboo-fantasy fuelled masturbation sessions every night. How could she entertain such nasty thoughts about her poor shrunken son? It was totally wrong, and yet that fact only seemed to make her ache to fulfil her fantasies even more, dominating her thoughts with an ever increasing frequency.
She sighed and leaned back in her chair, closing her eyes and returning her to her dirty fantasies. She shouldn't be ashamed about her sexual desires - she reasoned with herself. After all, they're totally private fantasies, right? Nobody knew of or could judge her for entertaining her unconventional, taboo fantasy. She bit gently at her upper lip as her mind rushed back to picturing the myriad of ways she might use and abuse her tiny son for her pleasure.
In the other room, Luke's tiny chest heaved from the exertion that it took to sprint into the nearby bathroom and find a suitable place to hide before his sister thundered in through the door behind him, her footsteps shaking the floor and causing Luke's teeth to chatter with each stride. Just before she entered, he had managed to slide along the white tile floor and scramble behind the toilet brush container, immediately adjacent to the toilet itself. He grinned and tried not to breathe too loudly while catching his breath as he watched the reflection on the tile on the wall of his enormous sister cursing and looking around frustratedly for him. He saw Margaret stop, and then move to close and lock the bathroom door. Was that a smile on her face?
"Oh no." He thought to himself. "Now I'm really in trouble."
"So you little twerp. I know you're in here somewhere. You've let me no choice but to flush you out of your hiding place" Margaret said menacingly as she came to stand in front of the toilet.
Time seemed to move slow as she let her soft skirt slide down over the skin of her pert round bum, her cheeks flushing in anticipation of carrying out her new plan. Margaret felt goosebumps shoot up her creamy white thighs and she giggled as she stepped out of the fallen item of clothing in her knee-high white socks. Her panties were white with pale pink love-hearts on them today, and she hitched her thumbs into the elastic band of her underwear and began to draw them down slowly, bending over as she did so. She knew that somewhere in the room, her perverted little brother was watching. All it took was one wrong move to give his location away...
Luke stifled a gulp, his mouth running dry and his erection rising strongly as he watched the glorious sight of his giant sister's beautiful peach shaped arse through the reflection of the tile. The room had become very quiet as she performed her little striptease, but Luke knew his older sister well, and resisted the powerful urge to get a better look at the pale round moons of Margaret's considerable bubble butt, lest he give away his hiding place and allow her to exact her revenge.
Her panties slid down her smooth legs and hit the floor, and she took one delicate step either side of them, her feet still covered by her knee-high white socks and just more than shoulder width apart. Luke watched her bend forward seductively, swishing her hair out of her face as she looked over one shoulder to admire the curves of her own arse, and then she moved her hands to cup each of her round cheeks, pulling them apart to reveal her forbidden crevasse with her tight little asshole and beautiful pink pussy.
