6 months preggo stepsister needs a loan

My stepsister Laya is 6 months pregnant and her belly is starting to show now and turning me on. I'm sitting in our basement when Laya comes home from shopping. Her areola are darkening from the pregnancy and I'm dying to suck on them. To my surprise, Laya comes into my bedroom not wearing a stitch of clothing. She tells me that she found this really cute dress while shopping but couldn't buy it because she was short of cash. I offer to make up the difference if she'll give me something in exchange. I really don't have to spell it out for her and with a smile Laya drops to her knees in front of me and starts to suck my cock. She gets me hard quick and I almost cum in her mouth right there. I put Laya up onto the bed and begin to eat her pussy. Laya is a smoker and lights up while I eat her pregnant wet snatch. I'm hard as I can be and can't wait to fuck my stepsister. She turns onto her back and I slam cock to her. We fuck in several positions before I cum in her cum hungry mouth.
