It all started when I bought my 18 y.o. stepdaughter a few new sexy outfits she wanted to try on for me right away. She looked so hot and was so aroused at the moment I kinda caught her vibe too and just couldn't say NO when she offered to give me head as her sign of gratitude. Next day she did it again and eventually I fucked her. Man, I hope my wife never finds out I like her tight young pussy more and we can keep our secret naughty shenanigans.
