A couple of weeks went by, and the family adapted; Benny and his mom subtly changed, but no one knew why they did and not Jenny and her dad. Jenny was slowly becoming more and more obsessed with her cock, with the feelings that came from it... and with the need to put it in something. She had to wear long dresses and skirts every day to hide it from everyone. Underwear and pants were both out of the question, though she did tend to go without anything on her legs at home, something which made the rest of the family uncomfortable. Once or twice a day in school she asked to go to the bathroom, secretly so she could jerk off, and almost got caught a few times.
Jenny's dad was trying very hard not to notice her, and avoiding everyone, really. The strong, confident man was completely changed by the loss of his genitals to his eight-year-old daughter, and the acquisition of hers. He was now quiet, withdrawn, shy. His wife didn't want to sleep with him, so he was in the guest room every night. He secretly feared Jenny using her new cock on him. A ridiculous notion, he knew, but terrifying nonetheless.
Jenny, meanwhile, was lying in bed trying to ignore her urges, not jerking off though her cock was rock-hard. She needed to fill something. More specifically... she'd heard the word recently... to FUCK something. Slowly she started thinking of things... and the only possible thing that popped up in her head was Daddy. He had her parts now. He knew that they were supposed to be filled. He wouldn't mind. She giggled to herself at what she was about to do, sneaking out of her room and into the guest room.
