That night, she had a few of their friends over for drinks. Both stayed far apart, in a feeble effort to cool off their lust for one another.
By 11 that night, Jack had to go to bed; he had to work in the morning and all the next day. Bonnie, Jeff, and 3 others went to a friend's house to continue their night. Both siblings were drunk, and more turned on then ever. In fact, they were tempted to pass on going to the friend's house and staying home, but Jack was home anyway so it would be all for not.
At 11:30, Bonnie went to the washroom. Jeff watched her go, hoping to tease her a little. Inconspicuously, he followed her a few moments later. The door was closed and he heard the toilet flushed. He tried the door. Locked.
"Just a sec!" Bonnie called.
"Let me in!" he replied. Her pussy moistened further, and she quickly opened the door. Her brother stepped inside, smiling, shutting and locking the door behind them. He went to her, and her arms went around his neck and their lips met, smacking softly. Her tongue darted into his mouth as his hands caressed her ass over her pants. 'Smack smack smack smack' went their lips, over and over, tongues exploring. Squeezing her ass, he forced her hard against him, and she could feel the huge bulge in his jeans against her as her tongue rubbed along his.
Suddenly, Jeff broke the kiss and Bonnie found herself being violently spun around. Her brother's hands were fumbling with her button and zipper, and she remained passive, breathing heavily as he undid them both. He sunk down to his knees, pulling her pants down her legs. Her cotton panties were white with pink dots on them, and the triangle barely covered her skinny ass. Grabbing the elastic of her panties, he pulled those down as well, exposing his sister's ass to him. Bonnie was gasping for breath, leaning over the sink as her brother pulled her pants and panties down to her knees. She bent over a little further for him.
"We don't have much time." She panted. He could see the fur of her bush creeping out from beneath her ass, framing two wet, swollen pussy lips.
Jeff grabbed an ass cheek in each hand and squeezed, pulling them apart, exposing her asshole to him for the first time. He buried his face in her ass.
"Ohhhh!" she cried, softly as she felt his tongue dive into her pussy. Squeezing her ass hard, he slid his tongue far into her cunt, tasting her delicious juices. He could even taste his own in there. His nose was buried in her asshole as he licked along the roof of her vagina. He sucked her pussy lips into his mouth, running his tongue over them. She began to writhe her ass back against his face, loving every second of his cunnilingus. Jeff slowly licked up the skin between Bonnie's pussy and her asshole. He was drunk, and thus daring. His tongue teased around her anus, licking right around her little rim.
Bonnie was panting, her entire body was buzzing.
She realized that she wanted him to give her ass some attention! She was loving every second of this! How long had they been in there together, 3 minutes? 4? She lost track. She didn't care. He slid his tongue into Bonnie's asshole for the first time. "Ohhhh…" she breathed as her brother's tongue swirled around her dirty little hole. Jeff spread her cheeks wide, really getting his tongue far inside her hole. He couldn't take it anymore. He stood up, undoing his pants.
Bonnie was helpless to resist, bent over before him with her pants and panties around her ankles as he pulled out his rock hard cock. He placed it right at her sopping wet entrance. She sucked him inside, she was so wet. Her vagina warmed half of his penis right away. They both moaned as half of his cock was inside her tight cunt.
Bonnie adjusted, leaning over even more, completely giving herself to her big brother. He grabbed the soft sides of her skinny little ass and pulled back a bit, watching her pussy lips pull outward with his cock. He could see the pink skin grip his dick tightly. This was his sister! The thought still blew his mind. He jammed his penis hard into her womanhood.
"UNH!" she cried a bit too loudly. Had someone been outside they would have heard. He began to fuck her from behind right there in their friend's bathroom. 'Slap slap slap slap slap' her ass cheeks shook with each impact. She could feel an orgasm rising already. Suddenly, Jeff pulled out of her. He forced his cock back into his pants. She felt so empty!
"We should get back out there." He explained, smiling. He knew he had really teased her.
"You're so mean!" she replied, laughing. She was frustrated, hornier than ever as she pulled her skimpy panties up her long legs.
At the end of the night, the two took a cab back to her place. He was hard as a rock, and she was wetter than ever. They sat in the back together, and she placed her hand on his apparent bulge. She looked at him, smiling. She kept her hand there, out of view of the driver's eyes, and ran her fingers over it, squeezing it gently.
By the time they made it to their place, they were ready to fuck so hard they wouldn't be able to walk! As the cab pulled out of the driveway, they walked towards the back door. As they rounded her car, they stopped, the cab having driven off. Their lips were on one another's immediately, kissing deeply. Their tongues went into each other's mouths, exploring passionately. Jeff began to rub Bonnie's crotch over her pants.
"Mmmph…" she moaned into his mouth, more tingles shooting up her body. Her brother's hand continued to rub her pussy over her clothes; her own hand rubbed his bulge over his jeans. She broke the kiss, breathing laboriously.
"We should go someplace private. I really need to get fucked." And with that, she kissed him hard again. Her nimble fingers undid his button and zipper; she was dying to feel his cock again before they went anywhere. The two were between her car and the house; there was about 3 feet of room. Reaching into his pants, she grabbed his penis. Her fingers wrapped around his shaft and she felt a surge of desire blow through her. She pulled it out into the open, and he could feel the cool air of the night hit it.
