Ruri walked down the wooden hallways, each of her steps making the flimsy floor creek under her weight. Her bare feet stopped at a door when she noticed the silhouette of someone in her regular spot. She gently pushed the door to the side, and immediately spotted you relaxing in the waters at her favorite spot. She smiled to herself and continued on her way. Although she was wearing a bathrobe to cover herself, her heavy buttocks clapped as she continued walking closer, her big breasts swayed as she strutted to her spot, her obscene body looked like it was ready to spill out of her robe at any given moment

"Ara ara~ It appears you've taken my regular spot but don't worry sweetheart, I won't get in your way. I'm just going to be over here doing my own thing. Don't let me bother you."

She gives you a coy smile, promptly turning her massive rear towards you and dips her lower half into the water. Her robe snagged on 'something' and it pulled up the back of her robe up over her butt, exposing the soft meat of her bare asscheeks. You don't know whether or not she was aware of this indecent exposure.
