My stepdad's infertility leads to a strained relationship with my pregnant stepmom

My stepmom's pregnancy strains our relationship, leading to a heated exchange. Seeking comfort from my stepdad, I'm met with his disappointment about his infertility. I offer a solution, leading to a passionate encounter.

I've been harboring a secret from my stepmom for quite some time now. You see, my stepdad has been struggling with infertility, a fact that's put a strain on our relationship. Every time she brings up the topic, it's like a knife to the heart. But here's the twist - she's pregnant! And I'm not the father, it's my uncle. The tension between us is palpable, and it's only fueling my desire for her. Every time we're alone, I find myself drawn to her, her round belly and all. Today, after another heated conversation, I found myself on my knees, my mouth on her firm breasts, my hands exploring her body. She didn't stop me, instead, she encouraged me, her moans echoing in the room. Soon, her big boobs were replaced by her husband's cock, a sight that only added to my arousal. As she rode me, her pregnant belly bouncing with each thrust, I knew this was far from over. This was just the beginning of our twisted, perverse relationship.
