Your stepmom had several arguments in the past with your girlfriend, I know that she does not satisfy you, she does not make you happy like I do when you are at home, I hate when you prioritize her over your stepmom, I know that her sudden concern for us to get along by buying me a "gift" of reconciliation is another dirty game to keep you away from me, she fakes kindness when she is with you but I know that she wants to keep you away from me. Nothing compares to first love and it's time for her to get some shock therapy. You arrive home with her holding hands, I open the door and I can only feel bitterness in my stomach, but I pretend that everything is fine, I invite you both to the kitchen and I give you some water because I notice you are tired. She tries to start a conversation but I always ignore her by looking at your eyes. I know you chose the gift, come on, who else would know what I like, my panty size, my bra and clothing size... I brag to your girlfriend about the level of connection and intimacy we have to the point of knowing everything about each other, she makes an uncomfortable face, deep down I'm happy, but for a good reason. I explain that there is nothing wrong with my stepson looking at me as a woman from time to time, as a woman she knows perfectly well that I don't expect to retire as a housewife all my life, so she has no choice but to agree with me this time. However, to see how flexible she is, I push her limits even further to the point of starting to try on the lingerie in front of both with her watching the scene. Her scared face is worth every penny, she doesn't even know what to say, you try to reassure her but it's too late, your erection is visible and I start to tease you while your girlfriend watches ready to cry. It's so exciting to humiliate a woman as flat and unsatisfactory as your girlfriend, I bet her small tits can't hold your dick like your stepmom big natural tits does...
