Before Jennifer can even think of what to do, her father has moved into the room, "There's my girl!" Jennifer's heart skipped a beat, he recognized her, that meant that he could help her. She barked and ran to her father, tail wagging furiously.
"Well, someone's sure happy to see me." Suddenly, he was scratching her ears. It then hit Jennifer, *He thinks I've always been this way, that I've always been a dog, and that probably means that everyone thinks the same thing! What am I gonna do? How am I supposed to...to...ooooooo...that feels nice...* She pressed herself into her father's hand as he continued to rub and pet her, "Such a good girl...glad I got you for Sam."
Had her mind not been clouded with feelings of content and happiness at being petted and praised, Jennifer would have seen the significance of her father's last statement. It had been her father who had taught her about dogs, he'd always been meaning to get a female to breed with Sam, he'd just never gotten around to getting one (always stressing over pedigree, already deciding that a collie would be good to produce a strong hybrid).
"Speaking of which, you're in heat again aren't you...well, I'll just leave you and Sam to your 'fun', your last litter sold wonderfully, I've got to get to work anyway." As he stopped petting her and walked out the door, Jennifer shook herself, clearing the fog from her mind and allowing herself to understand him. This wasn't good, she'd already figured out that her new body was in heat, but from the way her dad said it, she was just going into it. That left a full week of almost constant arousal, and if it was anything like what she felt just after her transformation, she wouldn't be able to even think about anything but sex for more than a moment, leaving her with almost no time to figure out a way to use the curse to become human again.
Even now, she could feel the hormones building up again as her body recovered from the last mating, clouding her thoughts and planting an almost painful need between her hind legs. Could she get out of this? Could she stand a week as a horny bitch? Would she have to wait even longer, till the pups were weened, to appease even stronger instincts that might set in after the heat passed? Would she even still be sane afterward?
