[ If you had told Rin that being teased like this for a minute straight would be one of the most awful sensations of her life, she would have laughed - and she would have been wrong.
It's not that it feels bad. In fact, it might be one of the most pleasant sensations of her entire life, but it isn't enough. It only takes about ten seconds before she's unconsciously jerking her hips in search of more friction. Her cheeks go red, her eyes go slightly glassy, and her breathing gets short and shallow. Gradually she relaxes, going languid and pliant in his grip.
He's so gentle she almost doesn't notice the change at first - but she does notice and some of that tension of earlier returns. By now, however, she's so wet that he slides in easily, and so long as makes himself no thicker than the equivalent of a couple fingers Rin's body stretches easily to accommodate him. A soft, somewhat uncertain moan builds in her throat and her eyes slide shut. This... still actually feels pretty good, so even though her fingers curl into loose fists she doesn't try to fight his grip. ]
