Gets up and turns around.

Chapter By: Mj. Spoilers

With a slight blush, Sarah turns around. Confusion is written on your face. "Sarah? What are you-?" She bends over and your mouth shuts.

"I'm sorry, big brother..." you can see her blush down to her shoulders as she speaks. "I don't really know how this is supposed to work. In school we only learned how to use our penises so far. But boys can use them too, right?"

Between the smooth, soft, youthful globes of her perky little butt, something beautiful appears. The taut dark star of her virgin butt, and the smooth, gentle crease of the pussy so often hidden by her thick nuts. As your eyes fall upon it, you realize this is the first time you have seen these since she was on the changing table as a baby. "Sarah... I'm not sure I'm supposed to... do this," you say hesitantly. Despite your reservations however, you find your hands drawn to her soft skin. You almost moan at the mere touch, so soft are her hips. You struggle to remember anything you have ever touched that was so soft. "I... I know men can do this thing with girls, but with my sister...?" You say that, but really, deep down your thought is on the cum filling your lower intestine. Can a boy who's been used as a toy by a girl also give back?

"Please," her whine dims the thought. "You were so nice to me and took care of my needs, now it's your turn." She rises on her toes and pushes herself against your hands, her little asshole catching the light as her cheeks are pulled apart.

You swallow. Well, you have come this far. You have no been able to say no to her yet, and she's actually pleading for it... You're going to do this. You can't stop here.

Heaving a husky breath, you swallow, then reach over to pick up the bottle of lube. Sarah forgot about it in her haste to fuck you, but you're too afraid of hurting her to do the same. She shivers as the slick liquid falls into her crack, then as you begin to spread it. Your thumbs pass over her hole, while your fingers take a moment to explore around, taking her smooth, ass cheeks from visibly soft to shining slick. The way her flesh swells between your fingers is mesmerizing, and you almost lose yourself in the act. "Oh Dougie," she moans, hanging her head, "that feels sooooo good. You're so good with your hands!" She giggles. "But I already knew that."

You chuckle and are suddenly overcome with the urge to playfully punish her insolence. Raising a hand, you bring it down in a soft, gentle love tap that makes her butt jiggle like pudding. She eeps, and you can see her dick jump between her legs. "Bad girl," you chide softly, grinning like a fool. She giggles back.

That's enough teasing. With another deep breath, you look down...
