Erika came home when her sense of smell alerted her to the presence of something new, something not human. She had studiously avoided Melissa but now she knew that her 'friend' was here and in a different form. It was hard, her canine dick was pressing into the band of her skirt. She needed to dispose of another load of canine semen into the world or she would continue to turn into something she didn't want.
Melissa meant trouble, if she was here it was like when she was stalking her after the incident in the swimming pool. As she was about to turn around and find some woods a nude form blocked her path. It was Melissa, now she was taller than Erika, with white skin, large (to her eyes) breasts, fiery red hair, freckles and blue eyes that burned in the late afternoon light.
"Melissa?" Erika gasped.
Her hard on was growing in strength starting to tear at the fabric of her clothes. She was trapped, her body knew it could detect real pussy, not the mental images that she dragged up to cum to. Erika was frozen the girl in front of her was a provocation, no an aggressor trying to provoke her into exploding.
"I know you Erika, you want to suffer, to be Christ with his cross (she could hear her friend roll her eyes) but you are only denying the inevitable."
"I can stop it..."
Melissa turned so that her body could be seen in profile, the swell of her left breast, the rump of her right butt, those long legs she imagined wrapped around her own body. Erika's panties were drenched with pre-cum her penis poked through like a spear through flesh.
"Let go..." Melissa crooned in her sweet voice "...let it go inside me."
