Marking you mine. (Oikawa Tooru x Reader)

He had pulled you on to his lap, his arms wound tight around your waist. "__-chan", Oikawa crooned against your neck. The brush of his lips sent a pleasant shiver down your spine. Why did he have to make it so difficult for you?

Oikawa pulled you closer, smiling against your throat for a moment before biting there. "T-Tooru". You desperately tried to hold in all the sweet sounds that threatened to fall off your lips. He could feel it and promptly started licking and sucking marks all over your pale skin. Your fingers in his hair tightened as moans filled his room. He had to mark you. You were his __-chan. No way was he going to let stupid guys think they could flirt with you in front of him.

"You're mine, __-chan", he declared the moment he was done. Not that you'd mind. You knew you were his.
