Kirby held onto her ankles, keeping her legs out of the way and her large breasts somewhat pushed together. Even while her mind drifted in and out, the pain of the cock in her ass driving out nearly every thought from her head, she understood that it was important to put on a good show for the man fucking her.

Even if she didn’t know his name or if he’d ever fuck her ass again, she knew it was her responsibility to moan, whimper, and scream while his cock destroyed her ass. She understood that he deserved to see her massive tits shake with each thrust of his cock and each of her ragged breaths.

She just hoped she didn’t pass out, so she could thank him properly for treating so well.
