You sat in the "laboratory" with Reiji, who was quietly mixing potions and writing in a small note tablet. He had made you stay with him as punishment for being late coming back from school.
You sighed loudly, surprising him. He jumped and quickly caught a glass before it hit the floor.
"Be quiet... I need my full focus right now."
"But I'm boooored..." you groaned.
He sighed, closing his notes, and stood up. He walked over to you. You grabbed a blanket and his under it. Reiji chuckled and pulled it off you. You could see him blushing.
He threw the blanket behind him, picked you up and took you to your room. He threw you on your bed and shut the door.
You giggled at him and his under the covers.
"Ms. (y/n), this goofing off has gone a bit too far, and now you shall get punishment," he said, pulling away the covers and pinning you down on the bed. You blushed at his sudden seriousness and realized you were in trouble.
Reiji smirked and nuzzled his face into your neck before unleashing his fangs. Your heart raced and you suddenly felt this teeth sink into your skin.
But it didn't hurt. It actually felt pleasurable. But.. Why didn't it hurt?
Reiji finished and looked into your eyes.
"Behave yourself next time, otherwise I will really bite you," he scolded.
"Reiji-sama..." you whispered.
"Yes?" he said.
He was still on top of you and looking into your eyes, which made you blush madly. You loved to make him irritated with your childish nature. That's just how you hid from him that you liked him.
"When you bit me.. Why didn't it hurt..?"
He smirked again and leaned close to your face.
"Well, my dear, let us just say I gave you a love bite and you are now claimed as mine," he explained.
You blushed madly and what he did next shocked you even more than that.
Reiji kissed you on the lips, softly and passionate. You knew this was real. You eased into the kiss, never wanting to break away.
Unfortunately, he broke the kiss to whisper in your ear.
"I see you agree to being mine, (y/n), so may I have my way now?" he asked.
You blushed and nodded. He pulled you up, sitting you on his lap facing him. He kissed you again, holding your waist. He then broke and switched to your next. You shivered at the thought of him really biting you, but thankfully, he gave you another love bite. You held him close as he bit you.
"I love you, Reiji-sama."
