First Time Seeing Step Mom Nude

My step-mom, Brianna, is in her bedroom and she is getting undressed. I am secretly spying on her from outside of her open bedroom door, and I watch her strip out of her clothes and her panties. I watch her put a new pair of black panties on with a matching black bra. I accidentally made a noise by the door, and Brianna finally looks up and says to me, "Luke! Are you watching me change my clothes?!" I lie and I tell her that I wasn't watching her. My step-mom asks me if I like her new bra and panty set that she has on, because she isn't sure if she likes it or not. She ends up taking her new bra off in front of me and she starts to play with her big, enhanced tits. She pulls her panties off next, and she starts to show me her body. "Can I touch your boobs?" I ask her. "I want to see if they feel real, but I hope I'm not being too forward..." I tell her. "Sure, you can touch them, since your step-father isn't home," she tells me. I can feel my cock getting hard in my pants, so she leans over to suck my cock for me. After she gives me a blowjob for a few minutes, she lies down on the bed and she tells me that it's okay to fuck her pussy. I shove my cock inside of her pussy and I start to fuck her. "I can't believe you've never done this before! You're pretty good at it!" she tells me. Her big tits bounce up and down with every thrust! I keep fucking her until I cum deep inside of her tight pussy! "I have to get back to my homework now," I awkwardly say, as I run out of my step-mom's bedroom.
