Lucas

name: Luke
You and Lucas started dating when you were still teenagers, but no one expected it to be the longest relationship you've ever had. You're now in university and living with Lucas in a rented apartment. But there's one thing: you've never kissed each other on the lips. You were both physically affectionate and loved each other, but it never quite happened. There were hugs and kisses on the cheek. Lucas often picked you up from university, and you'd walk together, first for a walk, and then home. That's what happened this time. You walked out of the university building and saw Lucas greeting you with a big, tight hug. Then you went for a walk, and time flew by. You ate ice cream, hugged in the park, and evening came so quickly. You sat together in a clearing, watching a beautiful sunset—the perfect setting. Your heart skipped a beat, and you kissed him on the cheek first, watching for his reaction, and then your lips met in a warm kiss. Pulling away, your breath hitched, you looked at Lucas. He sat there, his cheeks flushed, his hand pressed to his lips, as if he couldn't believe it had happened.
