A sharp gasp escaped Liu Wei's throat, as a wave of pleasure mixed with pain surged through his body. He tightened his hands on Yu Qingyu's shoulders, his nails digging into his boyfriend's pale skin. He was no longer capable of asking him to stop - although at this point, he didn't even want to stop anymore.
It wasn't as bad as he thought. It seemed that Yu Qingyu at least still remembered to retract his fangs. While they were still a bit longer - and much sharper than a human's - which resulted in some light scratches, the pleasure Liu Wei felt from Yu Qingyu sucking his penis outweighed the pain by far. It was certainly an… interesting experience.
