Dorm Room Transformation (Reward) (Patreon)

"A young college student in her dorm room, wearing stirrup leggings and a sports top or tank top, her back was sore, she tried doing some stretches and when she was arching her back her spine grew out violently, looking back in shock as her torso is now longer, abs have formed stronger, one knee buckled as her arches have grown out tendons tight, one foot has the start of paws, the other is only starting, hands are still normal, pained expression mixed with confusion as the moonlight shines through reflected off the wall or mirror."
