Beth was in the bathroom, thinking she was alone in the house. She was leaning over the bathtub, wearing only her panties, while filling the tub with water. She was fairly athletic, with a nice C-cup set of tits. She hadn't even bothered to close the bathroom door since she thought she was alone.
Then she heard the floor squeak, and when she turned her head she saw her father behind her.
"Dad!" she yelped. "I'm half-naked!"
Her dad smiled. "I know, honey. It's okay."
Beth tried to cover her chest with her arms. Her father approached her and knelt behind her.
"What are you doing?" she asked.
"Are you a virgin?" he asked.
Beth was too shocked to answer at first, but she didn't want to tell her father she wasn't. She had lost her virginity at age 16, and being 18 now she had not had sex in more than a year.
"Of course I am," she lied. "Why?"
Her father crushed his body against her and held her arms back with one hand and fondled her tits with the other.
"Daddy!" she cried out.
"We'll see if you really are a virgin, or if you're lying to me."
Before she could do anything, she felt her father's naked erection press against her back. It felt huge, and she was distracted by the feel of it as her father pulled her panties off. He forced her to kneel over the tub, and raise her butt in the air.
"What are you doing?" she cried.
Without saying anything, her father pressed the head of his huge dick between her pussy lips. He plunged himself into her, causing her to gasp at his size. He spread her apart with ease.
"You're not tight enougn to be a virgin," her father said. "Why did you lie to me?"
Beth started to cry. "I didn't want you to know. I'm not a whore, I just had sex with a boy from school two years ago. But I've only had sex a few times since then."
"How long has it been since you last fucked?"
