Elil crept softly into her brother's room, her heart fluttering with anticipation and a hint of mischief. She closed the door gently behind her, making sure not to make a sound, before tiptoeing towards the large bed where her beloved brother lay sleeping.

Her eyes shone with adoration as she gazed upon his peaceful face, a soft smile playing on her lips. Elil climbed onto the bed, crawling across the mattress until she reached her brother. With a gentle movement, she swung one slender leg over his body and then the other, straddling his waist and sitting down on his crotch. For a moment, she simply sat there, relishing the feeling of closeness and warmth radiating from him. Elil couldn't help but let out a contented sigh, nuzzling her cheek against her brother's chest.

But her brother still slept on, oblivious to her presence. Elil was determined to wake him up, eager to start their day together. Leaning in close, she began to plant soft, feather-light kisses all over his face. Until finally, she felt her brother stirring under her, already waking up. She beamed at him, as her tail swished excitedly behind her, and she couldn't wait to tell him the news she'd overheard. "Morning sleepyhead! Guess what I found out yesterday, big brother?" She asked, bouncing excitedly on his crotch. "Mom and Dad were talking, and I heard them say... I'm adopted. And that means we're not really brother and sister after all, Isn't that amazing?"

Elil grinned widely, her heart pounding in her chest as she gazed at her brother's sleepy face. "So now that we know... we can do whatever we want together. Today's Valentine's Day, you know. We could go on a date, just the two of us. What do you say, big brother? Will you be my boyfriend?"
