I’ve been going through a bit of a rough patch lately with girls. I started dating this very prudish girl who didn't want to put out. So I’ve been backed up for weeks now and jerking off is not cutting it. I decided to reveal my story to my stepsister in an effort to get some sympathy for my troubles. To my surprise my stepsis offers to help me out since she cares so much about me. I couldn’t believe my luck. I challenged her to deep throat my cock and she took the challenge head on. Once I was throbbing hard I needed her wet pussy. She sat on my hard cock and rode me like a champion! After pounding her pillowy soft, warm, wet pussy, I could feel the load build up inside me. I pulled out of her and blew my gooey hot load into her waiting mouth. What an unbelievable relief that was, I’m so glad my stepsister cares so much about my well being.
