One sister a futanari needing to pee but cant make it to the washroom. Her kind sister offers to sneak and hide on the playground equipment and let her futanari sister stick her dick in her pussy and relieve herself. They have an unfortunate problem the futanari is erect and aroused. Her sister rolling her eyes tells her to just fuck her. The story should evoke a sense of illicit pleasure and arousal, and make the reader feel like a voyeur peeking into the intimate of these characters. Be descriptive and use sensory language to make the experience as vivid and enticing as possible. Making sure to add dialogue
