Dazai might be more familiar than she knows with those warring instincts. Soft, indulgent, gentle things are nice, but harsh, cruel, violent things can be just as wonderful. The ecstasy a little pain can bring...he's well acquainted with that, as well. And maybe there is just a touch of sadism in the way he keeps every single one of those caresses light, the way he never quite goes too hard, only the faintest hint of ferocity in the way he devours her mouth, like she's a meal he's going to take his time consuming, and when he's done there will be nothing of her left but her bones. They aren't entirely separate urges, after all. Punishments can be given with love, and the gentlest touch can be colder than winter frost.

There isn't anything wrong with duality. There's nothing wrong with wanting both. Maybe he'll show her that, too. Later. Next time. When they're somewhere that isn't an alleyway, somewhere he can take his time and make her beg properly, leave her with tears in her eyes and sobs in her throat as her body quivers through another climax in an endless series.

He'll tease until she's begging for more, until she's telling him to take her, and then...
