"Hey mom! You're back early..." Erika said in a slightly hoarse voice. "Emily's home but she was about to leave" she added.
Erika's mother came into the living room, still wearing her work clothes. "I exchanged shifts with Samantha to leave work early just so I could get you some new clothes and another school uniform! But I'll have to stay at work later tomorrow, sorry hon. I'll put the clothes in your room and get changed to something more comfortable now!"
She left the room, and Erika let out a sigh of relief. Her half-dog, half-human penis did not seem to retract as much into her body as she had hoped, and she could feel her sticky canine balls against her skin beneath the dress.
Pressing Emily to get off the couch, she whispered:
"You need to go home now. I'll see you at school tomorrow. Don't tell anyone about our secret or you'll get in trouble! If anything weird happens, come to me and I'll help."
Emily nodded, picking up her school bag as Erika walked her to the front door and let her out. Erika then returned to the living room, grabbed a tissue and cleaned herself and the couch until no stain was visible. She also put her wet panties in the laundry basket; they barely fit anyway.
Erika's mom came back, wearing a loose fit tank top with no bra and comfy yoga pants. "Oh, you did not ask Emily if she wanted to say for the night? I know I'm very absent and I'm happy to let you have your friends around..."
"Mom! You know how strict Emily's parents are, they don't like last minute plans like that", Erika replied. In truth, it was probably best if they did not spend too much time together until Erika could tame her mating urges somehow.
"As you wish, honey! Another time then", her mother replied before dropping on the couch to watch some TV, exhausted by her day. "If you could take Max out for a walk, that would be great, sweetie. I'm too tired to do it but this poor dog need attention."
Erika shrugged and took the leash before going to the backyard to take Max on a walk. There was a faint scent of familiar sex on the porch which Erika couldn't quite place. The large husky jumped excitedly around her.
"Ok ok Max! We're going."
As Erika and Max were walking the pavement, she realized her sense of smell was much stronger than before. All kinds of scents filled her nostril and excited her interest in new ways. She could recognize different human and dog smells that had gone through the areas, and was starting to pick up differences between male and females.
As she walked by a specific wall covered in graffiti, a wave of canine smells hit her nose, and a strong urge started rising within her. She wanted to mark her territory, warn these other dogs that this area was hers. The idea sounded silly at first, but there was a pressure at the back of her spine and through her bladded that was growing more insistant by the minute.
Before she even realized it, one hand was lifting up the front of her dress while the other wrapped around her large penis, aiming at the spot, and she sprayed the area with a few bursts of hormones-filled urine, as Max was doing the same a short distance from her. Erika felt immensely satisfied, both by the physical release and the marking of her territory.
After her deed was done, she started walking back to her house. Meanwhile...
