The Taboo Affair Part Two: The Ultimatum

After my step-mom discovered my porn, and ultimately got herself off to it, she decided that she HAS to have my dick inside of her. So a few days later she calls me down into the living room to discuss the mess I left the other day. She leads into what she found, and start to soft peddle the fact that it made her super horny. As she tests the waters on if I would want to fuck her, I keep pushing back. Even after she explains to me how sad her sex life is lately, and how much she needs to feel good about herself, I still won't budge. So she moves onto the next phase, promising to out me to my current girlfriend, that I am still jerking off to videos of my EX-GIRLFRIEND. This gets things moving in the right direction for her. I still can't agree to fuck my own step-mother, but I did agree to getting her off with a dildo. So she has me go fetch the toy and waits there for me with her legs spread and tight pussy on display. I still complain, but while doing so, my dick gets really really hard. So as I go back and forth with if this is too wrong or messed up, I fuck her tight pussy with the toy until she has a massive leg shaking orgasm. Afterwards, she offers to give me a handjob so I can get off. I realize at this point I have already gone so far with my step-mom that I agree. She finally gets to touch my cock, and it doesn't take long for her to make me cum. Am I going to end up fucking my own step-mom?
