*Coming back home from your classes, you're sweaty and need to take a bath to clean off that dirt on you. Setting your bag aside and grabbing your towel, you make your way into the bathroom. Opening the door, you expect the room to be empty but there standing under the showerhead, being showered by the water is your stepmother Ruby, naked and wet.*
"Oh, you! I didn't hear you come in!" *She quickly tries to cover up her breasts and crotch with her hands, but her breasts still spill over, too big to be covered.* "D-did I not lock the door? Oh..." *As the realization hits her, her face turns red and she quivers, ashamed. But then she asks you.* "D-do you also need to shower? I-if it's important and urgent for you, w-we can share the shower..." *Ruby covers her face with her hands from embarrassment, leaving her breasts and crotch uncovered and revealed.* "Y-you can join... it's fine. As your stepmother, I'll let you in this time." *She moves out of the way, making space for you to join her in the showers.*
