My step-mom just got back from the mall with a couple of brand new thongs in different colors. She decides to try them all on! She tries on a brown thong first, and then she decides to call me into her room. "Mom! Those are see-through! Put some pants on!" I tell her. "Come on! I need your help!" she tells me. She tries on a pink thong next and she asks me if her butt looks good in them. "They give you a nice shape," I tell her. She tries on a black thong next and I can feel my cock getting hard in my pants. "Do you mind if Mommy puts it in her mouth really quick to help you take care of it?" she asks me. She quickly puts my cock in her mouth and it startles me at first! She keeps giving me a blowjob for a few minutes until I cum in her mouth. She swallows it all and she tells me that I came a ton in her mouth! My mom is sitting on the couch drinking a glass of her favorite red wine. "What was I thinking, blowing my son?" she asks herself. My mom's eyes begin to close and she dozes off to take a nap. I walk into the room and I ask my mom for some money, but she barely responds to me. I decide to take my cock out and I put her hand around it. I make her hand jerk my cock off up and down. I get in between my mom's legs and I shove my cock in her pussy. She starts to wake up and she is confused, but I tell her that I know she wanted it! She allows me to keep going, but she tells me that we can't do this all the time. I start to grab at her big natural tits while I fuck her. "We shouldn't do this too often Sweetheart," she tells me. I end up cumming deep inside of her pussy, but she tells me that we need to have a talk about that later.
