[Jikabi Baisen (Kazesaki Furea)] Kyouyama Kazusa no Sensei Kouryakujutsu (Blue Archive)

After a hard day, Sensei returns to the lab only to find Kazusa, the cat-eared, halo-wearing student council treasurer, waiting in nothing but her collar and dark thigh-highs, ready to "reward" him. The teasing escalation of her 'conquest strategy' unfolds as she ditches the rest of her uniform, mounts her willing instructor, and rides him with breathless enthusiasm. The climax hits with her eagerly guiding his hands to her sensitive nipples and finishing with a deep, hungry kiss, utterly spent and glowing with satisfaction.
