Her back against the stall's door, Emily squirmed in pleasure as the thing between her legs throbbed in the air, her underwear and school skirt at her ankles. Her hands grabbed nervously her buttoned shirt at her almost empty chest, while powerless she witnessed the swelling member spasm, taking on more canine traits as it grew in length and girth.
She hated it and never wanted to touch it, but she also loved how good it felt when things happened down there. The thought alone provoked another throb of pleasure between her legs, and a moan escaped her lips, echoing in the bathroom. She felt the pressure in her furry orbs increase.
Clear fluids began oozing from the thing, splattering on the tiles and some on her underwear. Emily didn't know what to do; she couldn't stop herself. It will happen even without someone to touch it. She closed her eyes and tried to ignore the throbbing that intensified in front of her, though she could feel the thing bloating at the base, forming a canine knot - and sending shivers up her spine.
Against her will, Emily's hips started bucking in the air in rythm with the spasms. The dribble of fluids became a continuous rope of glistening goo that followed the swinging of her erect member, running down her length as much as it spattered around her. She pressed her hands over her mouth to contain her moans as the inevitable was bound to happen.
Without any suspense or ceremony, a gush of cum burst forth and exploded all over the toilet seat in front of Emily, and she bit her tongue to keep from screaming lewdly. Unable to push herself to touch the disgusting piece of flesh, she watched it surge a couple more time as it spewed more goo up and down, left and right, making a mess of the bathroom stall.
As quickly as it came, the urge and intense pleasure were gone, and the thing slowly lost its hard quality until it became a soft lump between her legs. Emily almost staggered as, still out of breath, she pulled her damp panties up, and her skirt over it.
Too absorbed with herself, she had not noticed the whispers of her friends in the next stall.
