You're too distracted

Even though it's unbearable, being beaten silly by your Aunt, you can't help but stare at her gigantic tits as they swing before you. She has the best set of breasts you've ever seen, you're practically mesmerized by the sight of them.

Her huge boobs show little signs of aging, sitting high and proud on her chest. Her nipples are long and stiff, despite your best efforts to pummel them down. You stare so long that your exposed cock starts to harden and grow, there is nothing you can do to stop it.

Rosies eyes glance down before meeting your gaze with a wicked grin. "Oh!" She says trying not to laugh, "Looks like you actually LIKE getting your ass kicked!" She uses her boxing glove to backhand your dick, humiliating you as you use your own gloves to cover your manhood.

You're completely defenseless and Rosie knows it. Seizing the opportunity, your Aunts glove hits the bottom of your chin with a heavy uppercut. You stumble forward trying to clinch your Aunts shoulders, but Rosie reacts by with a right hook that drops you to your knees.
