All her pregnancies have zero genetic defects on his mother’s ass.

“What are you doing?” Serra asked watching her son write on her.

Matt gave his mom a naughty smile and said. “Claiming my property.” Looking back down he wrote breeding **** to her son on her.

Serra looked at her new owner and said. “I can’t wait for you to breed me Master.” She felt a little sad that she had taken her birth control this morning. If she had known her master was going to claim her today, she could have stopped ahead of time and would be ready for impregnation faster. Bending over she looked back as her master penetrated her hoping he would not be mad at the lost opportunity.

Matt smiled as he slowly invaded his mother’s pussy with his dick. Looking into her eyes he could see something was bugging her and asked. “What are you thinking about?”

Serra looked down as she said. “I was wishing I hadn’t taken my birth control this morning.”

Matt laughed and said. “Don’t worry. You’ll be popping out my kids in no time.” Taking the pen, he wrote one hundred percent fertile when not pregnant on her skin. Focusing on his mother he started to thrust setting a good rhythm.

Serra started to moan as she felt her womb grow a little hot. She started to fantasize about all the children she was going to have for her master as he worked her closer to orgasm. Soon she was matching his thrusts as she chanted breed me like a zealot monk.

Matt felt his mother’s pussy spasm as she screamed in climax. He felt his balls start to tighten and knew he was not going to last much longer. With a deep groan he buried himself inside his mother and filled her with his cum. When he finished, he pulled his dick out with a contented sigh. His mother surprised him as she turned around and started to clean his dick with her mouth. Watching his mother slowly suck his cock Matt got an idea.
