Your long term personal trainer has always been flirty, but this session she's invited you to her place. After listening to her sexy erotic moans during stretching you are very excited, she's much hotter than your wife and she knows it. She asks you to do an "adjustment" for her where you are practically in doggy style position and notices your stiff dick pressing against her yoga pants. She offers a nice "massage" rubbing on your penis while talking badly about your prude wife and her loser husband. You both decide to take things further, she bends over pulling down her leggings to reveal her perfect ass and wet pussy. You both fuck in various positions while she talks dirty and puts down your wife. You have an amazing orgasm and decide to keep this arrangement up.
