"Anybody home?!" Matt shouted into the quiet house. He let the front door close behind him as he dropped his backpack next to his suitcase. "Hello?"
"Matt?"
The voice came from behind him was a woman's and was at the same time strange and familiar. Turning around, Matt saw a blonde blur before he was almost bowled over by a person about a head shorter than he was. He felt slim but strong arms wrap around her chest and smelled a familiar scent of strawberries. Jen. There was a great sense of calm that Matt felt at his sister's arms around him. He had been away at college for a full 8 months without coming home and didn't realize how much he missed his family until then. Matt glanced down to confirm his suspicions and indeed saw a blonde head resting against his chest. With a smile, Matt took Jen by the shoulders and pushed her back to examine her.
"See I've got a sister," he said with a smile. "But you are waayyyy blonder than she is!"
Jen smiled back and gave her hair a little flip. "Do you like it bro?"
Matt opened his mouth to speak, but was momentarily lost for words. It wasn't the hair that struck him dumb, but his sister herself. When he had left for college in September, Jen had been growing into womanhood, still awkwardly trying to find herself. Yet over the last few months, she had grown into an amazing woman. Matt had seen pictures from her 18th birthday that had hinted at her beauty, but to behold her now, he was speechless.
Gone were the braces and glasses with scraggly hair and instead was a perfect smile set against soft, smooth skin. Her now blonde hair fell gracefully onto her shoulders, resting on the blue tank top she wore. The fabric hugged her body, her breasts perfectly round and pushing on the straps. Her legs were bare, her hips and ass tucked into a pair of jean shorts that left little to the imagination. Matt's breath was taken away as he beheld the woman before him
"Seriously do you like it?" Jen asked again. "I'm starting to feel self-conscious"
"No!" Matt said quickly. "It looks great."
Jen smiled and gave him another big hug. "I'm glad you're home. I've really missed you." As she turned and walked away, Matt couldn't help but watch the gentle sway of Jen's ass as she sauntered off. He was distracted enough that he stood there for a few minutes after, painfully aware of how hard his cock had gotten looking at his sister.
Carrying his bags upstairs, Matt tossed them onto his bed and made his way back downstairs. Hearing the TV in the den, Matt followed the sound to find Jen sprawled on the couch watching some show about housewives of some city. Pretending not to see her, Matt went and started to sit on her stomach.
"Hey! Cut it out!" Jen said with a laugh.
"Oh sorry," Matt said with mock sincerity. "Didn't see you there."
Jen slapped his shoulder and sat up. "Bastard."
"Oh you know it," Matt laughed, settling into the couch. "Where are mom and dad?"
"The Dominican."
"What?!"
Jen laughed. "Yeah they didn't tell you. One of their friends had a deal or something like that so they are on vacation for another week."
"And they left you alone?"
"I'm 18 now thanks," Jen said, rolling her eyes. "I'm not a little kid anymore."
Matt was almost too eager to agree with her. "No you aren't."
Jen rested her head on her brother's shoulder. "I've really missed you. It isn't the same not having you around the house."
Almost instinctually, Matt wrapped his arm around her, resting his palm on the side of her stomach. He pulled her close to him, feeling the warmth of her body as she tucked her legs under her and snuggled even closer into him. He felt the slow rise and fall of her chest as she lay against him and to Matt, nothing else in the world mattered at that moment. After a few minutes, Jen tilted her head up to him and Matt looked down at her. Jen's lips were barely parted and it looked as if she wanted to say something, but the longer the gaze lasted, the more intense it seemed to get. Maybe it was Matt's wishful thinking, but he could've sworn Jen was about to kiss him.
But the moment passed and Jen laid her head back down on his shoulder, this time shifting her position so her breasts were firmly against Matt's body. Not for the first time today, Matt felt a stirring in his groin and was suddenly worried his sister might notice. He didn't have the biggest cock in the world, but he was pretty well endowed and his shorts were loose enough to betray his erection. Matt shifted a little but his hand slipped down and he only managed to grab his younger sister's ass.
"You bad boy," Jen mock scolded. "Were you trying to grab my ass?"
"I, uh, no..." Matt started, suddenly embarrassed and stuttering. This only made Jen laugh more.
"It's okay brother," she said giving him a soft kiss on the cheek. "You're not the first guy to go crazy over my ass."
Jen got up off the couch and made her way outside, exaggerating the shaking of her hips for Matt's viewing as she walked away. Through the sliding door Matt saw her push the jean shorts to her ankles revealing a tiny red bikini bottom and pulled her tank top off to reveal an equally small top. The fabric barely covered her areola and offered a magnificent view of her breasts and ass. Jen's bronze body had seen a lot of sunlight and she kept it in great shape. Almost instantly, the erection Matt had been staving off was at full salute.
As Jen splashed into the pool, Matt made his way upstairs to his room, quickly closing the door behind him. He pulled his cock from his pants, all seven inches of meat laying in his hand as he frantically and almost desperately started to stroke it. Matt tried to think of porn stars or celebrities that he would fuck but his mind went back to Jen over and over again. He imagined her soft lips pressed against his, imagined her tight little body wrapped around his shaft, imagined her moans of pleasure as they fucked. It didn't' take long for him to finish, coming into a sock like he had back in high school.
His orgasm was intense, and it left him flushed and breathing hard. Matt cleaned himself up then collapsed in bed. He told himself that all he needed was a nap; that he was horny after not getting laid for two months and this was just a manifestation of that. He told himself he didn't want to fuck his little sister, but in the back of his mind he knew it wasn't the truth. Matt pulled off the remainder of his clothes and lay on top of the sheets in his boxers. His mind wandered, but it wasn't long before he fell asleep.
Matt was awakened by a bouncing sensation and awoke with a start to see Jen straddling him, bouncing the both of them up and down on the bed.
"Wake up!" She shouted, her damp hair falling like a curtain around them.
It took Matt a few seconds to fully awaken but the realization of his circumstance didn't take long to register. Every time Jen bounced, she was landing her still wet bikini clad pussy right on top of Matt's boxers and his growing erection.
"Come on," Jen repeated. "Get up!"
"I, uh, just give me a sec sis."
"What is this distracting you?" she asked, increasing the speed of her bouncing.
"Fuck yeah it's distracting me," Matt said quickly, "Knock it off."
Jen stopped bouncing for a minute and leaned in, bringing her face right to Matt's. "Make me."
With a grin, Matt rolled over, pinning her underneath him. They had played this game for years as children, even though Matt had always been the stronger of the two. As she had grown, Jen had become stronger too, and now she was wrestling Matt and giving him a run for his money. The two of them rolled around on the bed, each trying to get the upper hand on the other. Jen squealed and laughed as they rolled around until finally she grabbed a pillow and hit Matt over the head with it. In defeat, Matt lay down on the bed as though he'd been knocked out, supine and at her mercy.
Jen straddled Matt and raised her arms in victory, but instead of a smile, her face took a more serious look. As Matt caught his breath from the exertion and laughing, he realized in the struggle he had become fully erect again and Jen was sitting right on his boner. Jen seemed transfixed, her chest heaving as she caught her breath. Matt was aware of how warm her crotch was pressed up against his. He tried to shift himself, but only managed to rub his hard cock right over Jen's pussy. Her breath caught in her throat, but she didn't move away. Matt propped himself up and looked at her.
"I'm sor..."
Jen put her finger to his lips. Hesitantly leaning forward, Jen pressed her lips gently to Matt's. They sat like that for almost a minute, their lips barely touching, feeling their bodies pressed against each other's.
"I've wanted to do that for a long time," Jen whispered when the kiss was broken.
