Stepsister caught masturbating and instead of punishment she got nicely fucked

Thick and curvy Karlee Grey really needed to be hardly fucked, but she didn't wanted to disturb her poor stepbrother who has been already helping her with that problem recently. So she decided to casually masturbate, but she was moaning so loud that her stepbro heard it. And when he saw what she was doing, he couldn't stand aside and helped elder stepsister.
