Giantess Stepsister makes brother into thong for unaware stepsister
Title: The Unwitting Cum Doll of Giantess Stepsister Kira
Giantess Kira and her little brother were lounging on the couch together, lost in their own worlds. She didn't pay much attention to him, occasionally absentmindedly swatting a stray hand away when he tried to touch her. Unbeknownst to her, he had a plan.
As they watched TV, he slowly slid down her back until he was nestled between her cheeks, out of sight. He held his breath, hoping not to be discovered. For a moment, he felt safe and warm, but then the giantess began to move. Her massive frame shifted, causing him to be pushed and pulled in ways he hadn't anticipated. He let out a soft moan as she ground her hips against him, unaware of his presence.
Time passed, and soon the giantess grew impatient. She couldn't find whatever it was that was bothering her behind. Frustrated, she rose from the couch, giving him a glimpse of daylight. Desperate to remain hidden, he scrambled back into her crevasse.
Kira hadn't noticed him before, but now that he was back in her ass crack, she couldn't ignore him any longer. She bent over, pretending to search for whatever was irritating her. Her breath fanned over his face as he squirmed in fear. She teased him, telling him he'd better come out or else.
Her words sent shivers down his spine. He knew she meant business. He tried to whisper a plea for mercy, but his voice was muffled by her flesh. Before he knew it, she had grabbed him and pulled him out of her ass. He let out a yelp as the cool air hit his sensitive skin.
She laughed cruelly, her towering figure looming over him. She secured his hands and legs to the back of a thong, the material rubbing against his sensitive areas. With a wicked grin, she informed him that his fate would be sealed until his stepsister returned home.
Hours passed, and the giantess's stepsister finally arrived. She undressed without noticing the tiny figure hidden within her underwear. Unbeknownst to her, she was standing on top of her little brother, his body serving as a makeshift thong. Her farts rained down on him, making him squirm in discomfort.
Just as he thought things couldn't get any worse, his stepsister noticed something was amiss. She reached back and felt the strange bulge in her thong. Her eyes widened in horror as she realized what it was. She shrieked, causing the giantess to turn around.
"What's wrong?" Giantess Kira asked, her brow furrowed.
"You've ruined my lucky thong!" her stepsister wailed.
Giantess Kira's eyes narrowed. She'd had enough of her little brother's antics. With a cruel smile, she informed her stepsister that since he was already in there, he would be her new lucky charm. And so, the unwitting cum doll of Giantess Kira was born.
