Tactlessly broke into the ass-fuck of a sleeping sister

The room was dimly lit, the light from the moon streaming in through the window. In the corner, a sleeping figure lay peacefully. Suddenly, a figure emerged from the shadows, their face illuminated by the soft moonlight. With a gentle touch, they caressed their sister's body, feeling the curves of her figure. Then, with a single smooth motion, they entered her ass, thrusting in and out in perfect rhythm. Despite her sleeping state, the sister's body was alive with pleasure, her moans of ecstasy filling the room. As the figure continued to thrust, the intensity of the pleasure increased, until they both reached a powerful orgasm, their bodies trembling with joy.
