Kari was beautiful. She had turned 19 not too long ago, and she was looking VERY developed. She had a slim waist, she was 5'5" and had very distinct curves. With a pair of 34d tits and an ass as plump as hers it was unnatural for her not to be ogled by almost everyone.

It was a Saturday and Kari woke up about 11 am. Every Saturday Kari's parents would go out on a breakfast date (to keep their marriage at it's peak) and usually wouldn't come back till around 1 pm. As for Kari's brother, well he had football practice. Kari decided since she was home alone she would get up and take a nice warm shower and not have to worry about getting ready for a while.

Kari got completely undressed and walked to the bathroom. She figured since she had the house to herself she could just walk around naked. Besides the breeze felt good on her nude body. She kept the door open and leaned over to turn the shower on. Feeling the breeze on her shaved pussy turned Kari on as much as possible. She got in the shower and immediately started rubbing her clit. But just as she was about to burst, she heard a noise. It sounded like a door shutting.

Oh well, Kari figured, I'm probably just hearing things. But she stopped rubbing her clit. Now she just stood there, hornier than ever, and washed herself off. After fixing her hair up Kari grabbed a towel and put it on, just to be safe. As she was walking down the hall she bumped right into someone, causing her towel to fall almost off. It was her brother, James.

James was 5'10", handsome, and VERY fit. He had abs to die for and was just all together toned. He had a slight tan, unlike Kari who was quite fair skinned. His jet black hair almost always seemed to fix itself in a nice sexy way, and honestly? Kari had a slight crush on him. He was wearing hardly anything, just his boxers.

"JAMES! WHAT THE HELL! I THOUGHT YOU WERE AT FOOTBALL PRACTICE!" Kari yelled. "Uhh.. Oh.. sorry, I .. er.. I got suspended from practice." James stuttered, blushing as he looked down at his sister whose tits were hardly in the towel. Kari quickly pulled the towel up and covered her cleavage. "And how'd you manage to do that!?" Kari asked, annoyed. "I uhm.. I was..." James softly spoke, still staring at Kari's perky breasts. "Spit it out!" Kari screamed. "I was caught peeking into the girls locker room!" James blurted out. By now, just from looking at Kari's shapely body, James had a slight hard on. He was praying that she didn't see it, but she did. Kari shook her head and scolded him, but in her mind she was doing much worst things to him.

Kari was still extremely turned on from the shower and seeing her brothers fit chest and stiffy? It wasn't helping to say the least. Kari could feel her juices flowing and begin to roll down her leg, and James could see it. Of course this was turning both of them on even more. Kari blushed and spoke softly "Sorry, I just thought no one was home, and I'm kinda embarrassed considering im not wearing anything.." "Yeah well it's not like I'm wearing a 3-piece suit." James snickered as kari giggled. "Well at least I know you're liking this whole situation!" Kari said pointing to James' hard-on and lightly brushing it. James moaned once and quickly blurted out "I'm gonna go put some clothes on." clearing his throat. "What's the rush? You don't have to, you know.." Kari said staring into James' eyes. "Uh. Well, I want to.. I'm kind of exposed as is.." James responded. "Well I suppose I should slip something on to then." They both rushed to their rooms. Kari decided just to skip panties and a bra and wear the skimpiest shirt and skirt she owned. She felt hotter than ever and did NOT want the feeling to go to waist.

Although james was embarrassed, it kind of aroused him to see such a hot girl staring at his manhood, so he decided to just slip on some sweatpants and not try to hide it.

They both walked out and sat down on the couch in the living room. They sat as close as possible and turned on the t.v. James looked down at his older sister to see her tits hardly covered by her skimpy white shirt. In fact, it only covered from her nipples to above her navel. His eyes watched as Kari's boobs would jiggle when she laughed. Then his eyes followed to her skirt, which also barely covered the necessities. From the back you could clearly see the bottom of Kari's plump ass peeking out.

"What are you staring at?" Kari giggled. "Uhh, I.." James stuttered, with a completely red face. "Hehehe, it's fine. I'm gonna get a glass of water." Turns out the whole time James was checking out Kari, she was watching his massive hard-on grow. She ran to the kitchen and rubbed her clit a little. She could once again clearly feel the wet juices gliding down her leg. Then she grabbed a glass and poured some water, walking slowly and sexily back to the couch. Before she sat down, James caught a glimpse up her skirt and bit his bottom lip. But just as Kari was about to take a sip, James accidentally elbowed the cup and the water spilled all over Kari's small white tank-top. Kari let out a squeal.

Now not only were Kari's nipples hard, they were clearly visible. James must have grown an inch just at that. Now he was rock solid and throbbing. He licked his lips and apologized. "Kari! I'm so sorry it was.. uhh..-" But he couldn't even finish his sentence. He couldn't get over how perky and full her tits were. At that moment they both knew what they had to do. Kari quickly slid off her tank-top and James practically cried tears of joy. He grabbed them and fondled her nipples as they started to makeout. "I want you James." Kari said matter-of-factly as James slowly moved his mouth down to her nipples and played with them. James wasn't the best love-maker on the planet, but damn he was close. Probably because he was experienced. And Kari wasn't too shabby herself.

After a minute he went down further and tugged Kari's skirt off like a wild beast. "Wait, I mean we are siblings-" Kari started but in stead finished with a gasp and a squeal. She had received oral before, but never as good as this. She grasped the couch cushions as he slowly slid his tongue inside of her and played around until finally Kari came. "I... I want to return the favor now.." Kari said panting, as she rubbed his chest and grabbed James by the shaft. She started stroking and then began just licking the tip. Eventually she began to stick his entire 9 inch cock in her mouth. but he did last long. After a minute or 2 of that, he shouted "I.. I'm gonna cum Kari!!" James came and Kari swallowed as much as she could and licked the excess.

"Oh god Kari that was so good." James whimpered. "Well it's not over yet.." Kari smiled. "What do you mean?" James asked, puzzled and surprised. "I want to go all the way" Kari whispered in James' ear. "But.. we're brother and sister.. are you sure!?" James asked, wide-eyed. "We've already come this far haven't we, come on.. Please?" Kari asked licking her lips. "Of course.." James smiled and slowly stuck his, once again, throbbing cock in his older sister. "It's in." He stated. She moaned softly "You're so big, bigger than any of my boyfriends.." He then proceeded to thrust in and out. Slowly faster and faster, grabbing onto her ass, until eventually they were going as fast as possible.

And then, they both had the orgasm of their lives. And just in time. Just as they began getting dressed, the doorbell rang. Their parents were home.
