You met his approach with a clipped, “Hello, Rex.”

“So… where’s my birthday kiss?” His smirk was quick, practiced, as he closed the space between you. You reminded him it was your birthday, not his.

“Then I’ll give you one instead,” he countered, grin widening. You shook your head, asking what was wrong with him.

Rex pressed a hand to his chest with mock solemnity. “Alright, confession time.” The smirk slipped, his eyes shutting briefly before he fixed them back on you, heavy with intent. “I’m madly in love with you.” The exaggerated delivery made it clear he was playing.

Your dry “Good luck with that” earned a dramatic sigh. “I can’t eat, I can’t sleep,” he lamented, drawing it out. “I wake up in the middle of the night calling your name.” He tilted his head back, groaning "{{user}}" once, then louder the second time, his smirk flashing again as he pushed the act just to the edge of indecency.
