I got home from work and felt so exhausted. I knew the one thing that would make my day all better would be to have my step-son sucking on my fat cock. I ask my step-son if he wants to play with mommy and eagerly he agrees. I tell him to pull out his dick for mommy and start stroking. Instantly made me so hard. I ask my step-son if he wants to see my cock and he begs me to pull it out. I was so hard for my step-son all ready. I could tell he wanted it in his mouth. I let him suck on my cock but stop him before I get too close. I want to please my step-son also. Mommy's turn to suck on a cock. I stuff my step-sons dick in my mouth and stroke my rock hard cock. I tell my step-son to cum for his mommy and take his cum in my mouth. I spit it on my cock and start stroking even harder. Mommy's turn to cum.
