Claire reached one hand into the bag of pads. She fumbled around in the bag, tossing several pads around, before her fingers closed around you. She grabbed your flat, stretched out body tightly, and removed you from the bag. Being unable to move or talk, you could only stare in horror, as everything unfolded. Claire held you out in front of her naked body in one hand, not sparing you a single glance, thinking you to just be an old, normal pad. She moved her other hand down to her pussy, and put two fingers on either side of it. She started to spread apart the lips of her vagina, and then slowly moved you towards it. She held you directly beneath the opening, and you stared up into her awaiting pussy. It wasn't cleanly shaven, but didn't have enough hair to be unattractive. It was certainly hot, in the very least, but you never wanted to be in this position with your own sister. As she lifted you up closer to it, you saw hairs along the side, and the inside was covered with sticky fluid. After what seemed like an eternity, you finally lightly presed into her pussy. What followed was anything but gentle. She roughly smashed you past her lips and straight into her vagina. You rubbed harshly around the inside of her pussy, and her hairs and juices soaked and grasped at your body. She firmly shoved you into place near her clit, and satisfied at her work, began to put back on her clothes. Slipping on her panties, the little light shining into her vagina was lost to darkness.
She finished dressing, and walked out of the room. The walls of her pussy moved along with her steps, crushing your thin body with their weight. You started to sweat intensely, as the heat inside was almost unbearable. Her soft muscles morphed around your body, and you were tightly held in place, straddled between the sides of her cave. The smell however, was delightful. It smelled like a mix of heaven and something you couldn't place your finger on. You quickly began to have an erection, which was almost comical, as your tiny member stuck up from the rest of your flat body. Her pubic hairs began to tug on your stiff dick, and some of her juices poured onto it. You stayed in this position for several hours of intense pain and horrible sexual pleasure. You tried to direct your focus elsewhere, but you kept getting aroused. Your sister was unaware to all thus incest going on however, and went about her day. Several times she would sit down, and you would be squished by her pussy closing tighter around you.
That night, while in her bedroom, Claire decided to replace you with a different pad. She stripped, and reached a hand in for you. Her lips parted as a few of her fingers entered, and began searching for you. Her fingers rubbed along her pussy, searching, but as she continued to fell for you, she started to moan. She was getting aroused by trying to find you. Her muscled began to shake, and you heard a rumbling sound, when suddenly a large wave of cum burst forth. It flooded you out of her vagina, along with all of the cum, out onto her bed. She screamed in surprise, as the juices surged into a puddle in the middle of her bed, with your crumpled body floating on top. She sighed, and began to speak, when a curious look crossed her face. She opened her mouth to speak...
