[Sena] I woke up and I was being sold in a pet store

A naked girl wakes on all fours inside a glass pet shop showcase, teary-eyed and squatting over a floor-fixed pet sheet while curious customers press in to watch her pee. When a shopper points out her 'excitement urination,' the staff decide she's a smart little pet worth training, buckling a collar around her throat and teaching her to give her paw and beg like an obedient puppy. She jolts awake in her own bed convinced it was only a dream, until a wire cage sitting in her room and a shivering pup wrapped in a towel blur the line between owner and merchandise.
