The thrill of potential discovery heightens her arousal. She pulls down her panties, revealing her round, firm ass, and spreads her cheeks, revealing her tight hole. She spits on her fingers, lubing them up before plunging them into her ass, moaning loudly. Her free hand strokes her hard cock, feeling it grow even bigger. She can't wait any longer, pulling out her fingers and positioning her cock at her asshole. With a loud groan, she pushes in, feeling her tight hole stretch around his thick shaft. He fucks her hard, her moans echoing off the tiles, until he can't hold back any longer, pulling out and cumming hard, his hot seed filling the toilet bowl.
