The sounds she makes are what push him to keep licking, to keep tasting that hot flesh and even go as far as to lick lower and let it slip and slide a bit forward into her opening in a mimic of what he's going to soon be doing to her only with his length. Because even if he didn't have to have intercourse with her, it's now beyond him doing anything but with the way she sounds and what it does to him. Her taste in his mouth helps little, either.

Finally, her pulls up from the wetness of her vagina, running his tongue slowly ( so slowly ) one more time over her swollen clit before he leans in once lifted to kiss her shamelessly, immediately sliding his tongue into her mouth as he fumbles with his pants to pull them down and expose his erection, only nothing the replied of having himself constricted from the clothing.

Breaking the kiss he speaks quietly to her even as he brings his hands back to grasp her thighs to once again spread her wide and keep her so, letting the tip of his cock brush against her folds. Feeling her fluids touch the tip of him makes his shiver a little, finding a need to force himself to not simply push into her right then.

"...I'm going to push inside and take you, now, Yukimura... if you'll let me."
