Part 3 Rob told himself over and over again that he wasn't going to use the VR again. He didn't want to experience anything like he did with his mother again. So Robert began to look into ways to change his experience, finding threads on the internet that gave him examples and instructions. Then he found it, he found a guide to use the VR to experience a giantess situation! Rob was super excited to get started and wanted to make sure he wasn't going to have any bad situation again. This time he locked his door, got himself in bed and placed the VR headset on once again. He then went through the settings, changing them to fit what the settings were in the guide from earlier, readied himself and hit the START button. Once more, the same blue to white light flooded his vision, he awoke in his room on the bed. He sat up, feeling a bit dizzy. As Rob looked around he saw his body next to him, but it was huge! He could see the pores on his skin, see his body breathing and making small twitches. It was remarkable! He wanted to experience more! Rob slowly climbed down off his bed and ran to his bedroom door. He slipped under the door and into the hallway as his older sister walked down the hallway passed his door. The sight alone both scared and aroused him like never before! She walked in almost a slow motion, as her feet planted to the floor, small dust particles lifted around her. He could see the small movements of her muscles under the skin as his sister passed. The Faint jiggles of her thighs and lower butt cheek, the pores on her skin, the small hairs and veins. Everything filling his vision, bringing his most desired sexual dream to life as a giantess walked by him, fading away into her room. Rob had to see more! He ran across the hallway and under his older sisters room. As he peered in from under the door, he could see her bent over, digging in her laundry hamper. The shorts she was wearing showing him her lower cheeks and a glimpse of her panties inside. He walked closer, staring up at the goddess before him. Robs sister, turned and walked to her dresser closer to where Rob was standing. She dropped her shorts and stepped out of them, kicking them back towards the hamper. She squat down, deep, as she looked into her dresser. Robert immediately rushed over to her. As he approached, he could smell a faint scent of sweat lingering around his sister's massive cheeks. Her panties, purple in color, barely containing her massive round cheeks as she squat. The faint outline of her pussy lips poking through the panties made Robert hard. He drooled a bit from the entire experience and look before him. Robert's sister stirred a bit before standing back up, leggings in hand. Robert watched as the panties bunched and sucked themselves deep between the thick cheeks of his sister as she stood. He was so enamored by the sight of his sisters ass that he failed to notice her foot! Robert's older sister stepped towards him, at the last moment her toes made contact with him. He was shoved down, covered by her toes! Sweat, drying on her toes, stuck him to her. Robert tried to scream as his sister's full weight pressed down on him, he couldn't breathe, let alone scream. She stepped again, this time pulling Robert with her toes as she did. Robert felt himself lift into the air, high up as his sister stepped into her leggings. As her foot slid inside, Robert fell off falling into the folds of the leggings, screaming and spitting up lint and sweat. Robert's older sister continued to dress, pulling her leggings up. She felt something in her leggings towards her ass. She pulled and tugged on her leggings before squatting down once again, whatever it was must have been taken care of as she stood back up, not feeling it anymore. Robert screamed until he was met face first with ass flesh. He wriggled abit which caused his sister to adjust her leggings, she shoved him between her thick cheeks as she squat. The heat was the first thing Rob noticed, followed by the dampness caused by the sweat as he landed between his sister thick cheeks. He tried to yell out before she stood back up, sealing him between her fatty flesh. The taste of grime and sweat mixed with the heat immediately giving Robert a gross mixture. He coughed in response as the massive cheeks began to grind him between them. His sister sat down to put of her shoes, as her ass contacted her bed, Robert smashed into the flesh of his sisters ass once more. He could barely breathe from the heat and pressure. She stood back up and began to walk once again. This time, the way Robert was positioned caused his still quite erect penis to rub against the skin of his sister. The dampness and heat creating a natural lubricant as his tiny member slid across her asshole. He struggled, trying to stop the rubbing, as his sister continued to grind him between her cheeks as she walked. Leaving out the door into the summer heat, the sweat began to pick up. Robert inched closer to climaxing as his sister walked to her bicycle. He held it as long and hard as he could, just as his sister swung her leg over the bike seat. He couldn't hold it any longer as his sister sat on the bike seat, sending Robert's tiny form pressing hard into her anus. Robert came hard, spasming into his sister's anus before she let her full weight fall onto him. He struggled to breathe as she pedaled, he felt his ribs break, the air be pushed out of his lungs. He tried to claw at his sister's massive brown anus but his limbs were pinned. He felt himself fading as the air left his lungs completely. Finally his legs snapped, then arms before he finally faded. Robert awoke in his bed gasping for air and coughing. The VR headset fell off him as he sat up, looking down he saw he came while in the VR headset. He thought hard about what he experienced and wanted to see if he could find a way he couldn't die or be hurt from the settings for next time...
