He always felt there is something weird about his stepsister. Since the day they met a few months ago, it looked like she developed a crush on him, even though she knows that is a forbidden love. As he was sleeping in the bedroom, she came like a thief in the night and sneaked in his bed, butt naked. Just being close to him made her so horny that she had to wildly finger her pussy under the blanket. His naked sister kept finger fucking her wet pussy next to her sleeping brother before she made a move on him and woke him up. The element of surprise worked, as when young naked girl grabbed his morning wood and took it in her mouth, he stopped yelling and arguing how this is a wrong thing to do. Such a beautiful girl! I love her smooth skin and her fine features. She has long, slender legs, smooth pussy and gorgeous breasts. He was pleasantly surprised by her skills as he rewarded her by letting her ride his shaft. Her shaved pussy might be looking small, but as they started fucking, soon he realized that he could go balls deep inside of her. Skinny naked girl licked her lips and softly gasped as he kept hammering his long cock in and out of her tight pussy, gripping her hips and giving her more. This little slut probably already has a lot of experience. No matter what position they tried, including missionary or doggy, the slim girl took it like a champion. In her mind, she thought that she can’t miss this opportunity to prove her worth, and make this only the first in the series of their sexual adventures. She shouldn’t worry, as her stepbrother felt the same as he was spraying his cum all over her face before she licked his shaft for the perfect ending.
