Mommy loves you so much. Since you've been getting so close lately and fully expressing your love for each other the only logical next step is to impregnate your mommy. This way you will always have something you made together in love. It doesn't take much convincing once she strips down and tells you she is ovulating. She sucks your throbbing dick getting so excited that you'll soon be pumping her fertile womb with your seed. You get great views of her riding you, pounding her from the back fucking her deep in missionary before you give her every drop of your seed deep inside her. What a romantic gesture!
