You are back in town for the weekend and end up hanging out with your ex-girlfriend, Claudia. You always loved her muscles when you were dating, and she teases you, telling you she has only gotten more muscular in the intervening months. She flexes, showing off her biceps and shoulders, and tells you she knows exactly how hard it makes you. As you jerk off she tells you how hot she finds it, and encourages you to cum all over her huge tits while she flexes for you.
