Part 4 Robert spent hours researching and learning to program the settings for his VR fantasy. He felt guilty that it was his sister he was listing so hard for this entire time but couldn't help himself, he wanted more! Robert configured the settings perfectly. He had a plan, he'd shrink himself again. This time he would get himself to his sister while she was sleeping before planting himself between her legs. He would have ample time to explore her body and get all the thrills he wanted well before she woke up. Just in case, he adjusted the settings and made it easier for him to move and gave him invincibility so he wouldn't die from anything he hadn't thought about. Robert laid down, headset on, ready for his ultimate fantasy to come to life. He awoke shrunken on his bed once again, this time instead of carefully climbing down off his bed he left off to the carpet below! He dropped like a rock, slamming into the carpeted floor below with a hard thud. He knocked the wind out of himself but otherwise was fine! He slowly stood up and cheered to himself before he made a mad dash to his sisters room! Robert popped out from under his sisters door, looking up at her sleeping body. In minutes Robert scaled his sisters massive bed. The sight of her sleeping body excited him. Faint light flooded in, giving him a silhouette of his sister, barely covered by her bedding. She was laying on her stomach with one leg up higher than the other. This gave Robert a small opening between her blanket and her leg that he ised to slip under her covers. He walked closer to her crotch, the damp musky air filling his lungs. His dick hard at the thought of exploring the massive mound in front of him. Robert walked up to his sisters gigantic unshaven pussy, he stuck his tongue out and licked hard at her lips. His sisyers stirred a bit which made Robert even more excited. He slowly inserted his arm, then began to move it up and down. His sister faintly moaned as Robert felt her getting wetter and wetter as he played around. He then stuck his other arm in, thrusting it in and out. This caused his sister to get even more wet. Before long, Robert was covered in his sisters juices as he pleasured her to his best ability at his size. He got so wrapped up into it and ended up slipping on her juices and slamming into her lips. His sister moaned and lifted her hips before she turned over. Robert flipped and slid deeper.into his sister. He began to panic and thrashed around which caused him to slide deeper and make his sister moan more. Soon enough Robert felt pressure on his back as his sister in response to the stimulation began to thrust her fingers into herself. Robert screamed as she shoved him deep inside her, pleasuring herself with his body and her fingers. Robert swallowed a ton of her juices as he screamed while she dug deeper into herself. At some point Robert's sister awoke, very horny. She didn't feel much of Robert and any movement he caused just aided her horniness. She decided to grab her dildo and turn it on. The dildo erupted to life with a loud buzz as she circled her hole teasing herself. She grabbed her dildo and aimed it at her hole before cramming it inside her and pressing hard into Robert's tiny body! The vibrations of the electric sex toy vibrated Robert's sisters entire vagina, causing him to shake violently. Robert came hard from the stimulation as more and more juices filled the area. Robert's sister was getting close to climaxing as her walls tensed hard, pushing Robert deep against her womb and the massive dildo. Robert was then flooded with her juices as she came hard, shaking and thrusting her hips about as she did. She slid the gigantic dildo out, leaving her brother inside her, bruised and exhausted. Robert's sister rolled over to her side, sealing Robert's exit as she fell back to sleep. Robert tried a few times to free himself but with no luck. He was stuck.inside his sister as she slept... Robert managed to fall asleep inside his sister, only waking when she emptied her bladder the next morning. Robert figured he needed to get her attention to be saved or he may be stuck inside her forever! Robert began to thrash around and kick and punch to try to get his sisters attention, this caused her to get excited again and get wetter. Robert slid from her build up of juices and dropped down again. His sister in response felt his movements and began to fish him out, freaking out that something was inside her! Massive finger wrapped around Robert and fished him out, swinging him around and up real high to her face. Robert screamed and waved as his sister focused on what she was seeing. Robert's sister smiled hard at him when she saw it was a tiny person. His sister looked around before licking him real quick and lowering Robert to pussy lips again. Robert thrashed around as his sister's words echoed through his head... "I've always wanted a shrunken sex slave! You're going back to keep me company all day!!" Robert was at the mercy of his giantess sister, thinking he was her own personal sex slave. Robert felt mixed feelings on this as he was sealed back into his sister's panties as she dressed for work...
