Wanting to change things, she surprises him by applying for a "Mating Leave" timed to a beastman's heat cycle. Summoning her courage, she tells him she wants to spend a passionate night together. Sshir then bares the fangs he had been hiding and warns her, "I've been holding back all this time... prepare yourself." He desires her far more intensely and fiercely than she ever imagined.
