StepMommy's Sneaky Impregnation

Your Step-Dad is away on an overnight business trip leaving you and Step-Mommy all alone. She has been working out a lot presumably in an attempt to grab your Step-Dad's wandering attention. It will never work, she is way to good for him. You watch her work out, she looks so hot in that new gym set... no you can't think your Step-Mom's a MILF...can you? Maybe she feels the same way about you... You grab your chance while you can, sneaking into her bedroom at night. You know she wears an eye mask so she will never know it's you. You just want her to feel loved again exactly what she deserves. She says you feel different... bigger but you are so much more gentle and loving than your Step-Dad which makes her suspicious. When she pulls her mask off and comes to the realization that her Step-Son has been fucking her instead to your surprise she wants to keep you inside. You feel amazing. Just don't cum inside, it's Step-Mommy's fertile time and her and your Step-Dad are currently trying to get pregnant. But when she climaxes all over your cock and you feel her throb over you you cannot help but to blow your load inside of Step-Mommy. Now this gives Step-Mommy an idea, why don't you get her pregnant instead. Your idiot Step-Father has had no success in impregnating her and your young seed shall do just the trick. It can be your little secret, sneaking around behind his back and let's be honest... he deserves it for not giving Step-Mommy all the attention she deserves. The two of you become addicted to each other, fucking every chance you get whenever Step-Dad's back is turned. There is nothing more that the two of you want in this world than to leave him behind and for the two of you to start your own Step-Family together. You both love each other in a whole new way now... and this magical new thing between you is just getting warmed up...
