“Are you sure? Now’s your chance to back out,” Will breathed, watching his baby sister below him. She looked up at him with hungry eyes, and pulled his face down to hers. Tess cupped his jaw as she planted a wet kiss on his lips, pushing her tongue into his mouth eagerly. His cock twitched at her entrance, and he fought every urge to not slam his member into his virgin sister’s hole then and there. He wanted nothing more than to bury himself in her, over and over, until he’d dumped all of his pent-up load deep into her waiting womb. It occurred to him, then, cock dripping precum into her waiting cunt, that he had no idea whether or not she was on birth control. The next thing that he realised was how much harder that made him, and he swallowed the idea that he might actually *want* her to get pregnant. Tess pulled back from the kiss, hand still locked on the back of his neck and holding him.
