"Wha- N-No I dont have fangs..." Swap stuttered out an excuse once you asked him the question. You had a small suspicion about it but you really didn't have a reason to until you began to add things up. Swap would always joke about biting you...? He would occasionally bite you with your consent though... sometimes you would wake up with bite marks. He only went out with you at night, and not to mention he usually hid his mouth when he talked.
