He chased after Yi Chen's warm tongue with his and when he couldn't get what he wanted he parted his lips slightly and gently grazed Yi Chen's lower lip before lightly biting it.
Yi Chen let out a lazy "um" sound as his tongue slid into Zi Han's mouth. Their tongues entwined together in a sensual dance with sounds of turbulent breathing and ambiguous kissing echoing in the empty room.
Zi Han raised his leg and Yi Chen's hand caressed it from his bent knee up his thigh with the temperature between them rising spontaneously.
Bzzzzzz..... bzzzzz!
That was the sound of Yi Chen's light brain buzzing breaking this erotic atmosphere. Yi Chen ignored it and continued kissing Zi Han but Zi Han didn't cooperate. He moved his face to the side avoiding Yi Chen's greedy lips.
Yi Chen didn't mind. In fact, he took the opportunity to kiss his cheek and neck with his heavy and hot breath brushing against Zi Han's skin.
