Stepson I need your seed impregnation fantasy

Step son Thank you for coming to talk to me like I asked you to after your date tonight. There is something really important that I need from you. I know that you and your girlfriend are having sex and that is OK I am just so thankful that you wear a condom every time. Now mommy needs something from you. When your step dad left, he left without giving me the only thing that I wanted from him. Another BBY. I need you to sit down and let me tease you to get your cock nice and hard and build up the perfect load to impregnate me with. I see you are getting hard already. You like watching mommy ! Don't be scared! I promise you after you feel mommy from the inside you will never get hard for another dumb basic girl again! Let me suck it and and lick it for a little while. I know you want to cummm but DO NOT until you are deep inside of me. I need to ride you forwards and backwards to get a good build up of seed in your balls before I let you cumm.
