Mark slowly and silently opened Kate's door, careful to not let the light fall on her still form. He had wanted to do this for as long as he could remember; to touch his sleeping sister. As his eyes fell on her figure, he knew there was no turning back.
Her skinny body rested peacefully, illuminated faintly by the light which seeped into the room from the hall. Steeling himself, he crept inside her room and closed the door softly, so that if she woke she hopefully wouldn't mind the intrusion. As he walked to the foot of the bed, his eyes alighted on her circumstance more fully. She wore baby blue sleepwear and was mostly free of her blanket; her arms and legs were uncovered while her torso was only partially obscured.
Kate was 18, a year younger than him, and she had a cute face and body, thin with small breasts. As he ran his eyes over her body, he saw that her eyes were still, indicating a deep sleep. He also saw that her pale feet were bare, as usual. He would often shamelessly gawk at her feet, and even took pictures sometimes. Her feet were usually his exclusive masturbation material. Luckily, she didn't seem to know about either, her naivety seemingly without end. He hoped if he was caught she would explain it away as an innocent action, and especially not tell their parents.
He crouched down gingerly at the edge of the bed, his face now level with her bare feet. All the while, he watched to face to make sure it didn't wake. Kate wasn't a light sleeper, but not particularly deep, either, so he needed to be careful. Ever so slowly, he brought his nose forward until it was just in front of his face. Breathing, he smelled her sweat fairly strongly. The erotic scent instantly made him erect, and he continued to indulge in her aphrodisiac pleasures.
After a few minutes, he pulled his face away to check hers. Her eyes were still free of movement, and she hadn't moved at all. He was emboldened, but although he had lost his inhibitions the same was not true for his caution. He moved his hand adjacent to her feet, less scared than before. He touched her sole and then pulled his hand away. He garnered no reaction. Eager at this development, he gently laid his palm against sole. Again, she didn't move, even as he kept it there.
Her feet were soft and ineffably warm against his hands. Gradually, he traced his fingers around her feet, before stroking her soles, back and forth, simulating a footjob. He still earned no reaction. Smiling, he undid his pants, letting his hard penis feel the air of his sister's room. He knew that this was much riskier than anything else, but he felt indomitable and no fear pervaded his feelings of arousal and power.
He brought his dick to her foot and lightly pressed it against her sole. She recoiled and brought her foot back. Mark crouched down quickly, hoping if she had woken up she hadn't seen him. After a while, he peeked over the top. Her eyes were closed, and she was still in the position she went into after moving. He breathed a sigh of relief, and decided to do something less likely to wake her up.
He wanted to ejaculate on Kate, but knew that the stains would be obvious, so he thought of other options. He could always cum inside of her, but her only exposed hole was her mouth, and she would taste his semen, so it wouldn't work. If he pulled her pants down, he would have more options, but it was very risky, and he would also have to remove her panties. If he penetrated her butt, she would probably wake up, so he decided that he had only one choice.
He reached his arms out and began to slip her pyjamas off, watching her face intently. Amazingly, she didn't wake up, probably because the air was just as warm as her clothes were. When he had gotten it down almost to her knees, he stopped, and looked at the fruit of his efforts. He was not dissapointed, and he saw Kate's hairless, pink pussy in full. He was astounded that she hadn't worn panties, but cherished the sight nonetheless.
Bending down, he placed his nose over her hole and breathed softly. She smelled amazing, and his tongue lashed out almost instinctively. Her sexy taste covered his mouth, and his penis grew even harder than before. Reluctantly, he pulled himself off of her, knowing that if he continued to eat her out she would wake up.
The fact that she hadn't moved while he tasted her pussy made him confident that he could cum in her without her waking up. He wasn't about to fuck her or relive his experience with the attempted footjob, so he merely jacked off until he felt he was close. He stopped masturbating momentarily and pressed the head of his penis lightly on her hole. He pressed into her, needing to be slightly inside to actually cum inside of her.
However, as he moved to penetrate her, he met resistance. Pushing slightly harder, he ripped her hymen. He cursed himself for his stupidity, knowing that he had just deflorated Kate while also probably waking her up. He figured that since there was no way to cover up his act, he would just stand near the bed, ready to talk with her when she woke, and smooth over the damage.
As time passed, however, she hardly shifted, and still slept pretty soundly. He couldn't believe his luck. He had just deflowered his sister, was about to cum in her, and was going to get away with it. He looked over her adorable body, the sight filling him with lust. He was ready to cum again. Placing his glans into her, he felt her hot, wet insides envelop him. Throwing caution to the wind, he stuck the entire length of his penis inside of her. The sweet succour of his sister's insides brought him the intense release he had always wanted to experience with his sister.
