It's after hours at the gym & you're getting a private training session. Things take an unexpected turn after squats when your compliment of her glute gains turns into you being made to her worship her superior ass. Looking at it jiggle in front of you makes you totally fucking weak, you ache from the depths of your soul. She wants to take the training to the next level and asks if you've ever had your hole stretched. Not knowing if you heard her correctly you ask her to repeat herself and before you can blink she's strapped up, wearing a massive cock that has you trembling with fear and... strangely, desire. Imagining those powerful glutes and thighs burying that thing inside you has you leaking... it becomes obvious she isn't going to give you much of a choice...
