Sarah dropped her bag onto her bed and ventured to the kitchen in search of food. A groan muffled by her brother's door stopped her. There was a muttered curse followed by a name. Her brow knitted together as she inched closer to the door.
"Damn it, Kat," he hissed. The unmistakable sound of flesh moving over flesh mingled with the words falling carelessly from his lips. Taking a chance, she carefully opened the door to snoop. John's arm was stroking his flesh of meat as he relaxed in the chair. His face was twisted in concentration. Her eyes drifted to his other hand and she gawked. A black lacy thong was gripped in his hand. Her black lacy thong. The one she had left behind for Zorro.
Shutting the door again, she backed away from her brother's room. Thousands of questions swarmed her brain as she couldn't help but listen to her brother's big finish. As quickly as her brother had, she pieced the events of last night together. She should have felt disgusted. Her skin should be crawling with the need to be scrubbed clean. Instead, she was soaking wet and in need of relief.
When she entered her room, she realized something. He had said her fake name. There was a chance he had no idea it was her. Looking at her closet, a mischievous smile played at her lips. Her parents were out of town for the weekend. Meaning she had three days to toy with her brother. If it was a fluke, no one had to know. If it wasn't...
Pulling on a mini denim skirt and a white crop top she stepped in front of her mirror. The top was snug and clung to her tits, leaving the top of them partially exposed. The skirt should have been a little longer had it not been for her ass forcing it to ride up. The air licking at her sensitive pussy felt good as she once again made her way to the kitchen. She made one stop on the way in John's room.
John was leaning against the counters as he took a sip of water. He coughed as his sister entered the room. Her costume last night had been the most revealing thing he had seen her in, until now. The short skirt allowed for the bottom of her ass to be seen. Her hard nipples could be seen through any top, but not the color. The thin white material hid nothing.
"What are you wearing?"
"Clothes," she tilted her head with a smirk. She fought the amused smile as he tried to discreetly adjust the tent in his pants. The poor boy had just gotten off and was still looking for more. John watched as she licked her lips, her eyes trained on his crotch.
"Are you feeling okay?"
"Truthfully, no." She pouted and John had to fight off a groan. "I gave a guy my number last night and he never messaged me."
"Maybe he lost it."
"It's kind of hard to lose something written on a body part." John raised an eyebrow as she took a step forward. "You never told me about your night."
"It was fine," he stammered as she hopped onto the counter next to him. She crossed her ankles but let her knees fall apart. She knew with her skirt riding up and her knees spread he could see her goods from any spot in the room.
"Wow. Just fine? It was Halloween, Johnny. Anything can happen on Halloween."
"Okay, it was a great night."
"So, you did get laid," she chirped leaning to rest her head against the cabinet behind her. "Was she a slutty witch? Or maybe it was a naughty vampire?"
John narrowed his eyes on his sister. Turning his back to her, he set the glass near the sink and leaned on the counters across from her. He wanted to put space between them. Only problem was he now saw what she was doing. Everything was on display. Her chest was pushed out from leaning back. Her skirt had ridden up just enough that he could see the sheen on her bare pussy.
"Neither," he mumbled trying to look anywhere but at her.
"Well, it had to be someone wearing black," she pulled the thong from her pocket. It dangled from her finger as a lump grew in John's throat.
"You went into my room?"
"You kept my panties?"
"They aren't yours," he choked out as heat raced up his neck.
"Want to bet?" The evil grin she wore made him want to pace. "I bet you a blow job, they are mine."
"Listen to yourself," his confidence was returning. She knew. That was the only explanation for all of this boldness. Her outfit. The never-ending questions. The black lace swinging from her finger. He really could use a mouth wrapped around his throbbing cock. That was if he won the bet. If he lost... His eyes dropped down to her parted legs.
"Someone sounds worried they'll lose."
"There's no way you can tell me that they are yours." Yup, he was about to get the blow job he should have gotten this morning. Lust had replaced logic minutes ago and there was no undoing this now. They were both too far down the rabbit hole.
"We'll see about that." She adjusted the thong in her hands, raised them to her mouth and licked the thin dividing line. She moaned softly and John nearly came in his pants. Pinching the tag she held it out stretched between them. "Get on your knees big brother."
"There is no way could you tell by licking them." She crocked a finger at him, beckoning him closer. On shaky legs, he took the few steps only to stop between her legs. She wiggled the tag in his face. In pink thread were three letters; SIN. "Doesn't mean they're yours."
"Sarah Iris Nunen." John's jaw went slack and a string of giggles left Sarah. "Now then, you going to pay up or back out?"
Even defeated, John slunk to his knees while keeping a brave face. Sarah pulled her feet up on the counter beside her. The cool breeze against her wet pussy sent a shiver through her. The moment her brother's hot breath chased away the chill, Sarah closed her eyes. His rough hands weaved between her legs. He grabbed her ass roughly and pulled her closer to the edge of the counter.
Unlike Lily's determined menstruations, John didn't dive right in. He took his time, nipping the soft flesh of her thighs. His hands kneaded her ass as he licked the juices that had coated her puffy lower lips. His tongue flicked over her clit before dipping between her folds. Sarah moaned as one hand tangled in his dark hair. His hands slid the back of her thighs as he pushed forward.
There was no doubt the familiar tongue had plenty of practice over the years. With each trace through her, over the bundle of nerves, down her lips and back into her depths she felt every bit of pleasure. John smiled at the methodical way he was getting back at her. He was good at keeping girls on the edge of sanity this way. If she wanted him to bring her over to the side of bliss, she was going to beg for it.
His thumb brushed over her lips and she bucked her hips at the new feeling. His hands were rough from sports and the manual labor he had down over the summer. The combination of rough with the smooth glide of his tongue brought another moan.
"Fuck, Johnny," she mumbled, "You sure you know what you're doing?"
Her brother's only response was a finger joining his tongue between the folds. His finger curled the slightest and she arched her back as he found the hidden button. She moaned again and John smiled. He nibbled her clit then took it into his mouth. Just as before, his tongue was painfully slow as it swirled around her. His finger curled again and this time her body jumped from the sudden pleasure.
Her walls tightened around him, and he added a second finger. He could feel she was closer. The unmistakable sweet juices from the night before were flowing faster. Her pussy was begging for more as they clenched around his slow sawing fingers. She squirmed, causing her hips to grind against his face.
"I need to cum, Johnny." He slowed his fingers and his tongue. There was one, maybe two, words he needed to hear before he let her off the hook. "Oh god."
