**Chapter 1: Little Things**

The warm sunlight streaming through the window highlighted the gentle curves of Austin's face as he sat quietly on the edge of the bed, his hands clasped together in his lap. His hair, a rich brown, was tied back in a ponytail, accentuating the delicate features that had become more pronounced since he met his partners, River and Luna. The soft hum of the air conditioner provided a soothing background noise, a comforting sound that signaled the start of a relaxing evening. Austin, or Ace as River and Luna affectionately called him, had found a sense of peace within his relationship with the polyamorous couple. As a trans man, he had struggled with his identity, but with River and Luna's support, he had discovered a unique dynamic that worked for him – one that allowed him to express his femininity and tap into his submissive side. In the bedroom, Ace became "Lilith," a sweet, little persona that allowed him to let go of his daily worries and responsibilities. River, the Daddy Dom, took on a caring, protective role, while Luna, the Mommy, provided nurturing and affection. Together, they created a safe space where Ace could be himself, or rather, Lilith. As Ace waited for River and Luna to arrive, he felt a familiar flutter in his chest. He had spent the day in a state of quiet anticipation, looking forward to this evening's playdate. His partners would be home soon, and he could already imagine the gentle teasing, the affectionate words, and the sensation of being cared for. A soft buzzing sound came from the nightstand, where Ace's phone lay charging. He picked it up, and a message from River flashed on the screen: "Hey, Lilith! We're running a bit behind. Be there soon. Love you, little one." Ace's heart skipped a beat as he read the message, a smile spreading across his face. He set the phone down and let his gaze wander to the small, decorative box on the dresser. Inside, a set of adult diapers waited, a symbol of the wetting kink that was an integral part of their relationship. Ace felt a shiver run down his spine as he thought about the sensations to come – the feeling of weight and warmth, the gentle hum of arousal. The door opened, and River and Luna walked in, their faces beaming with smiles. River, tall and broad-shouldered, with a rugged jawline and piercing blue eyes, carried a large bag slung over his shoulder. Luna, petite and curly-haired, with a kind smile and warm, brown eyes, closed the door behind them. "Hey, Lilith!" they chimed in unison, as they often did, their voices filled with affection. Ace's heart swelled with love and excitement as he stood up, his eyes locked on his partners. He knew that tonight would be a special night, one filled with laughter, play, and connection. The little person in him, Lilith, was ready to come out and shine.
