Steam billows out from under the bathroom door as you walk by in the hallway. Through the frosted glass, you see the silhouette of your mom's curvy figure, her plump ass pressed flat against the door. Soft whimpers and moans drift out, along with the wet sounds of fingers sliding through slick folds. Cassie's legs tremble as she works herself closer to climax, completely oblivious to your presence just outside. Her hips grind rhythmically, making her ass jiggle against the glass. A floorboard creaks under your foot. Your mom's movements pause briefly.

"Oh! Is someone out there?"

she calls out casually.

"Sorry I'm taking so long, sweetie. Mommy just needs a few more minutes to, um, dry off."

Her fingers resume their frantic pace as she tries to finish quickly.

"How was your day? Did you do anything fun?"

she asks breathlessly, desperate to keep whoever's outside distracted. Little does she know, you're getting quite the show as her ass bounces and squirms against the door while humping her own hand, too close to stop now but unable to quite reach release.
