I love my stepdad's dick

My stepdad likes to help me get inspired artistically. He is super encouraging about it. But ever since I broke up with my boyfriend, I do not have a model to draw. So, my stepdad is letting me draw a very special part of him. After I fucked him, the younger inexperienced boys are no longer good enough for me. My stepdad thinks it has gone too far, but I told him to fuck me again or I would tell mom everything. I have a bad conscience because I pushed him to do it, but it was totally worth it. Deep down, I know he liked to fuck my wet pussy from behind, while looking at my tight ass. I even let him cum all over my face, mmm daddy's cum is the best!
