Mount and ride Ana's cock
From Create Your Own Story
With a loud pop, you release her cock from your mouth. Before she can complain, you strip your shirt, gym shorts, and boxers off. While you give her a show, Ana quickly sets the bar back in place and sits up on the bench. You climb up over her lap and lower yourself down into a squat. Ana looks at you hungrily. "Put it in," she growls. Bracing one hand on her muscular shoulder, you use the other to guide her fat cock into place and slowly push down against it.
The girth of Ana's erection is so ridiculous that you can't seem to make any headway at first. Then Ana impatiently grabs your hips in a vice-like grip. "Sit on it, you little baby," she says harshly. She pulls down, and the head of her cock forces its way into you painfully. Mercilessly, Ana guides you up and down in short, rough bounces until two-thirds of her length is embedded in your burning colon. Then she releases you and leans her elbows back on the bar behind her. With a filthy laugh, she orders "Now bounce on it."
You do your best, but the cock is so big and painful that your erection has flagged. Your useless prick flops pathetically against Ana's abs, which stand out impressively thanks to her posture.
