Amy runs her fingers through Lina's tail, captivated by how soft the fur was. Amy was barely aware of Lina's deep breathing as she stuck her head into Lina's tail, giggling as the fur and her whisker rubbed against each other.
"Your tail is so soft," Amy said, her voice muffled by the fur. Amy's own legs went numb and she fell into Lina's tail. The tingling running down her back told her what was happening. Her cargo pants tightened as her own tail pushed against the seat of her pants. Amy could do nothing but continue to embrace her friend's tail as her own ripped its way from the confines of her pants.
Amy let out a sigh of relief as the object grew out, now free of the fabric. Her entire body went rigid with pleasure as fur grew in on the object.
Things settled down, and Amy was finally able to release Lina. She looked back at her tail and gave it a test wiggle.
"Amy," Lina said, still breathing heard, "what's happening to us?"
Amy looked up at Lina, surprised at what she saw. Lina's ears were now those of a skunk, rounded, covered in fur, and firmly seated on top of her head.
