The attempted strut made her laugh even harder, at least until he kissed her. Then she melted in his hands, kissing him back fiercely and pushing until he sat down in the water again. “You can do better,” she challenged.
“Mmm, better than this?” He thrust his tongue into her mouth, suddenly and without warning, as he straddled her lap and pressed her against the edge of the tub. Moaning into the kiss, their bodies pressed together and he held her in place.
Summer wasn’t at all sure where he’d learned to kiss like /that/. Isaac had never kissed her like that before in the entirety of their two month relationship. Just like that under the inexorable pressure of his mouth and body she was ready again, whimpering for his touch. She wasn’t even sure what it /was/; the strength of him, or the fact that she trusted him utterly, or just him picking up the challenge she’d laid down. “Please,” she begged incoherently.
