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 step-mommy needs something from you. When your step-dad left, he left without giving me the only thing that I wanted from him. Another
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 watchin...

Don't be scared! I promise you after you feel step-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. Boy if you cumm Anywhere except for step-mommy's pussy you will never get to feel it again so be patient and let me feel how good it feels so I can climax at the same time as you when you finally cum in step-mommy's pussy and impregnate me. It's the best way you know. I will eventually let you shoot your big load deep in my pussy and not waste a drop of your precious seed. See isn't it better without a condom and I know everything about step-mommy is better than your g/f. Sure you can keep seeing her but good luck getting hard for anyone but me ever again.
You are such a good boy doing what I tell you to do you deserved to bust that nut inside of me and make me cum so hard.
MMMM maybe next time after I am pregnant I will let you cumm somewhere else. I get so horny when I am pregnant.

*** there was an intended creampie at the end but I just couldn't waste a drop oh and also the tube kept disconnecting. It's a new toy ;-)
