That was a good question. He knew enough to know what would probably not work, but what to do with the parts that would? The obvious answer was to do to her what she was doing. In other words, to stroke her vagina. But would she let him? A little something to test the waters seemed the thing to do, so the hand that had brought hers to him felt for the hem of her nightgown under the covers. His fingers, in searching, rubbed against her crotch several times over the two layers of fabric before hooking their goal. Pulling it up toward her head, he kept his eyes locked in hers. "say when," he whispered, trying to sound more confident in this idea than he was. When he somehow knew the hem was far enough, he broke eye contact for just a moment to steal a glimpse of her flat stomach, disappointed the covers threw a shadow over everything below it.
