Severus was horny. His wife didn't touch him any more. He had married her after her first husband died in a raid that ended Voldemort's reign. He had married her because he still loved her and her daughter needed a steady home life. He was coming to the conclusion that he made a huge mistake. She didn't love him, she never did. She only married him to keep Harriet in a stable home. Lily was never home anymore. She finally told him the truth that she had been cheating on him the whole time. He was devastated. He stayed though because of Harriet.
Harriet was beautiful. Her long legs, sinful lips, and apple bottom could turn anyone's head including Severus'. He really shouldn't be thinking about his 16 year old step-daughter like that.
Over the last few months though his patience was growing thin. She had been flirting and teasing him endlessly. He was frustrated.
He wanked to thoughts of her daily.
Finally one night his resolve broke. He had another night of restless tossing and turning while his wife was out with another man yet again. He got out of bed to grab a drink of water from the kitchen. He was passing Harriet's room when he paused hearing her moan. Her door was slightly ajar and he could see her naked on the bed, with her fingers playing with folds of her glistening sex. It was all too much. He just couldn't help it anymore. He stared open mouth as she fingered herself. He barely registered her quiet moan of "Severus," before he realized he walked into the room and closed the door behind him.
"Finally." She murmured. Severus paused. 'She planned this?' "Severus, please, I want you."
Severus started moving again. She watched with apt attention as he undressed. He climbed on the bed. "Are you sure?" He asked.
"Yes." Harry nodded emphatically.
Well who was he to deny such a tempting vixen. He leaned down and captured her lips with his. She tasted like treacle tart and chocolate. It was almost bitter sweet. He knew he should leave, but he couldn't deny himself anymore. He pressed his body down on hers and he felt her wet cavern slide against his hard cock. It was heavenly.
He paused one more time. "After this you shall be mine Harriet."
"Yes. Yours." Harriet agreed readily.
He took his hard member slid into her warm and moist vagina. It was perfect. Made just for him. He gave her a moment to adjust. Then he slid out and back in slowly at first. He kissed Harriet, slid his tongue in her mouth and rocked inside her. He rammed his rod in and out of her like an animal. He fucked her over and over. In and out, in and out. She was moaning and crying. So beautiful. He could tell she was close, he fucked her harder and harder. Harriet came hard, releasing her juices all over his cock. It was all too much as she tightened around him. "I am going to cum." He panted.
"Yes. Do it. In me. In me. Please." Harriet said wrapping her legs around him, trapping him but not completely, he could get out if he really wanted to. He should have said no and pulled out, but it was everything he ever wanted. He wanted to breed his darling step-daughter. He wanted to flaunt it in front of his wife. Show off his new toy. He swelled with pride and something else entirely at the thought of impregnating his underage step-daughter, giving her his heir, showing his wife and all the world that she was truly his. 'Yes, it's perfect.' He thought. He thrust into her deeper than ever and felt her cervix flutter as he tapped it. He spilled his potent seed deep inside her, where it had no choice but to plant itself within her, securing his line for the next generation. He sighed with contentment as his task was completed. He felt right. Harry was now his in every way possible. There was no denying it. Nothing could stop them now. He pulled out his softened cock and laid down next to her, pulling her to his chest as they calmed from their activity. He cleaned them and they settled down together. He knew they would have to talk, but they would do so later. They would do it together.
In the morning they agreed to date and Severus would divorce Lily and marry Harriet. They would live a happy life, all four of them (Harriet was pregnant with twins a boy and a girl).
THE END
