Happy Birthday Step-son! Step-Mommy has your cake lit with candles in front of you. She tells you to blow out the candles, close your eyes and to make a wish. Remember not to tell step-mommy what you wished for or it won't come true step-son. You close your eyes and and open to reveal your big boobed step-mommy looking shocked holding her massive giant blown up titties. Step-Son what in the world did you wish for? Step-Mom cannot believe she has grown two big round balloons looking down at her inflated chest. Step-Son what did you do? What did you wish for to blow up Step-Mommy's tits out of all proportions! Look at the size of these, they are gigantic how will I explain this to all the guests later coming round for your party. Step-Son are you getting turned on by this, are you getting hard for your step-mother's massive milkers. Now son I should be mad but as it's your birthday I guess this can be your present and I did mean to blow up some more balloons for your special day but now you can just stare at Step-Mommy's big balloons. They are starting to grow on step-mommy, the more I feel them and admire my new size the more I'm starting to get used to them. Step-Mommy encourages you to jerk off for her big jugs, showing them off from the side and bouncing them up and down. You've really given step-mommy a boost son, I want you to cum for Step-Mommy's tits, watch step-mommy bounce them while you grip your hard cock cover Step-Mommy's huge balloons.
