Sarah was nervous as she entered the gym, her tight little asshole already feeling stretched from the massive plug she had inserted earlier. She had always been curious about anal training, but she never expected to get an offer from her new personal trainer, who happened to be a black stud named Chris. As she approached him, she couldn't help but feel her heart race with anticipation.
Chris greeted her with a smile and led her to the training room. He showed her some exercises to help her prepare for their session, but all Sarah could think about was how much she wanted him inside her ass. When they finally began, Chris started gentle, warming up her ass with his fingers before slowly inserting the head of his massive cock.
Sarah gasped as she felt him breach her tight ring of muscles, but it was too late, he was already inside her. He started moving slowly, letting Sarah adjust to his size and girth. As he gradually picked up speed, she wrapped her legs around him, meeting his thrusts with enthusiasm. The feeling of being filled up by him was exhilarating, and she moaned in appreciation. Their lovemaking became fierce and passionate, their bodies moving in perfect rhythm. They lost themselves in the moment, oblivious to anything else around them.
