[BrattySis] Mercedes Mac (Stepsis Have You Ever Sucked A Dick Before – S37:E11 / 08.22.2025)

Mercedes Mac is focused on her homework when her stepbrother, Jason, interrupts her. She tries to be friendly, suggesting they hang out later to watch a documentary. Jason, however, is a complete asshole to her, cruelly telling his stepsister to only come find him when she’s learned how to properly suck a dick.

A week later, Mercedes marches into his room with a new kind of confidence. She announces that she took his advice, studied explicit porn videos, and practiced deepthroating with a cucumber until she perfected her technique. Now, she’s ready for the real thing. She immediately pops out her perfect tits and demands he show her his cock.

Eager to test her skills, Jason quickly frees his hard dick. Mercedes doesn’t hesitate, taking his entire length into her warm, eager mouth to demonstrate everything she’s learned. It quickly becomes obvious that a blowjob is just the beginning—she wants him to fuck her hard.

She starts by riding him in reverse cowgirl, bouncing on his shaft before finding herself on her knees, with Jason pounding into her from behind. When she rolls onto her back, he drives into her with deep, powerful strokes, making sure his stepsister is screaming in pleasure. To finish, Mercedes gets on her knees and begs for his load, and Jason erupts, covering her big, beautiful tits with his hot cum.
