Sam came first. "HAWWWWWW." She yelled loudly. Warm viscous liquid flowed around her hand in spurts. She had never had a wet orgasm before. She fell forward and rolled onto her back. Jen was going at it again, watching the screen of the laptop. She didn't even slow when the door opened. Sam sat up, startled by the sound of breaking glass. Tory, Jen's sixteen year old brother, had dropped his cup when he saw his sister and friend.
"Transform or Dare!" Jen shouted, seeing her chance to get back to normal. He didn't seem to hear. He was staring at his sister, fist in her pussy and braying like an ass. Sam waited, shaking her head, trying to keep it clear. She couldn't mess this up. He still didn't answer. She hoped that meant what she thought it did.
"Fine you get both. For your dare you will ask me Transform or Dare." She paused, the donkey sounds of Jen were making her wet again. Nooo she thought. Concentrate. "When I pick.. you will.. you.." Her eyes were locked on the front of his jeans. His cock bulged in his pants. Sam was vaguely disgusted by the thought that he was turned on by his sister but the thought quickly slipped away. "You will give me a hot soaking wet donkey pussy!" The lust hit her full force once again when she heard her own words.
"And after you will become a huge stiff donkeeeey CAWWWK with... with two heads!" She added, thinking about Jen's need but more about the idea of having two to herself. He asked her what he was told and she picked transform, eagerly.
"You will grow a huge wet donkey pussy." He muttered stunned. He tried to run from the room after but his legs had already started to fuse. His clothing shredded and fell as he fattened. His hair receded until his head was only a bare patch of skin. Slowly his arms retreated into the thick round mass he was becoming. His face became distorted, eyes and nose vanishing. His mouth became a thin vertical slit and began to move slowly to the top of his now soft bulbous head. His skin darkened as he began to shrink. Sam's mouth watered at the sight of the vein covered cock. Below her own pussy had darkened, grown. It was now a dark hairy mass, wet and pulsing. Tory tumbled to the ground, his feet fused and bubbling outward into a second head. Finally he stopped shrinking when he was only fifteen inches long.
Sam scrambled to the fallen object. She took Tory in both her hands and thrust the head that been his actual head and shoved him inside her newly gained lips. She pushed him in deeper than she had ever taken anyone or anything. Jen finally rushed over, aware only of what Sam held in her hands. Her mouth fell on the end that protruded from Sam's snatch and began to lick and suck as if she would devour it whole. The cock throbbed and pulsed as they fucked and sucked. Jen took her end then and shoved it inside her, although she could not get as deep as Sam had. They sat face to face, cock thrust into their pussy's and began to thrust forward. Sam leaned forward then, and wrapped her fingers around Jens neck. Pulling her close she buried her tongue in Jens mouth. They kissed and groped at each other until they both came around the massive donkey dick.
They both fell back at the same time, braying and moaning. Afterward they lay still, cock still inside each of them. Other thoughts entered and disappeared and came again. Jen thought of finding Kyle and getting revenge. Sam thought of using the curse to fix them. Jen thought of asking Sam to shove the cock into her ass. Sam thought of turning Jen into a horny jack.
