Brenda could hardly notice her subtle changes in comparison to her overwhelming desire to touch herself. She tried to calm herself down, reasoning that they had to get out of here as fast as possible. She dared to straighten her panties, or what was left of them before discarding them.
Still feeling itchy, she nervously quelled it with a slight scratch, but as she continued on she could hardly ignore her stomach pains and squirmed on the spot.
Mark had been leading the way back to the boat, all the while trying to ignore Brenda's stiffled aroused groans, mistaking them for frightened responses.
"It's not that far, come on. We can make it," Marktried to sound reassuring.
Finally he noticed that Brenda had stopped following him and turned to see her fall to her knees. She clutched her abdomen and crotch and rubbed them desperately through her coat. She looked up at Mark, and silently begged him to help her before her eyes rolled up and let out a sensual moan. She couldn't stand hold back any longer and was consumed by her desire to masturbate. She fell forward down on to all fours and kneeled her head low to the ground. With her right hand she finally found her clit and caked it with the juices of her moist pussy and the mud. Vigorously she rubbed it until she brought herself to a climaxe which brought with it several aftershocks of seemingly endless pleasure that rocked her body violently. She let loose a loud porcine squeal as she shook uncontrollably on the spot. She panted heavily and stiffed a small grunt before she fell over on her side, opening her jacket and revealing her changes.
Mark gasped as he saw her body had swollen and saw her new nipples. Brenda noticed them as well and eagerly touched them, jarring her shoulders as she thrust her hips up into the air with pleasure. She curled her knees and her feet began to stretch. Brenda rolled on the silky interior of the coat as her fingers found her crotch again and began sliding her fingers in and out of herself. Her neat pubic hair now blossomed into a hairy mass that covered her inner thighs and up her stomach. Hair grew all over her as she thrust her body up to the sky her free hand squeezing her new sets of breasts.
Mark tried to look away but couldn't. He was too fascinated by the horror and sexual thrill of Brenda's change. She continued to writhe and change before him but he made no attempt to stop her or to join her. He merely watched for a moment until she noticed him. No longer did Brenda plea for his help to stop her transformation, but to complete it. All he needed to see was the look in her lustful eye along with that tusk-filled smile that followed to know that he was now officially on his own.
Before he could run, however, he tripped over a log and fell over on to the ground.
