Jeff awakened to soft kissing on his face, and he realized there was a hand stroking his cock, gently. He couldn't have been asleep for more than 20 minutes. His breathing grew deep as his penis grew hard. He realized it was Amy. He smiled. That little nymph! He could hear her heavy breathing, and she kissed him on the lips.
Her tongue darted into his mouth, and he sent his tongue into hers. Her foot was caressing his leg, sliding around him as she inched closer. He could feel her run his cock down the fur of her bush until it hit the moist of her slit. It reached her hot, welcoming entrance and he couldn't help but push forward. Hot, silky moistness absorbed his penis inside, and he could hear Amy sigh heavily as she kissed him. Her vagina completely engulfed his cock, and he held himself there, kissing her softly. He kissed over her cheek to her ear, as he subtly writhed against her, sliding in and out of her with tiny strokes so as not to disturb his other sister.
"...So good..." Amy whispered so softly in his ear he barely heard it. She needed more, though. She needed to be fucked really hard, and he was barely moving in and out of her. He was so hard! He reached so deep! Her hot pussy gripped him tightly, and gave a lot of friction as he eased in and out of her.
"Jeff," she whispered quietly, "I need to have you all to myself. Let's go up to my room for a while." He kissed her once, sucking her upper lip. He then slid his hard-on out of her hungry twat. She rolled off the bed, her brother followed.
Bonnie, meanwhile, hadn't slept a wink. She was thinking about that night. About how unexpected her feelings were. How she loved her brother's cock, her brother's cum. Everything about him turned her on like never before. She suddenly felt slight movement in the bed, heard the quiet whispers, and then watched the two siblings sneak out of bed and up the stairs. She gave them a minute, and then she followed.
Jeff followed Amy up the stairs, eyes focused on her naked, skinny ass as she walked ahead of him. When they walked into her bedroom, she turned around eagerly, tits bouncing as she smiled at him. She put her arms around his neck, holding him close as she kissed him. His hands slid down to her ass, holding it as they made out. He squeezed her soft cheeks, lips smacking as they backed up to her bed. They fell on the bed, Amy opening her long legs for him as he fell on her between them.
His cock found her pussy on its own, without any further guidance, and he slipped into her wet tightness. "Ohhhhhhh..." she moaned as he filled her up with one stroke. Her eyes were closed, her head arched back. Her cunt felt so warm around his dick. So snug, even after all the times he's fucked her she still gripped him tightly. She wrapped her arms and legs around him, and his lips found hers. Amy and Jeff french kissed as they made love, his body was pressed tightly against hers. He was conscious of her breasts rubbing against his chest as he slowly slid in and out of her.
Meanwhile, Bonnie had crept up the stairs behind them. She poked her head into her sister's room and watched as her two siblings made passionate love, the light of the moon pouring through the window. She was surprised to find that she was jealous. What happened to her? She was never all that horny before, and the thought of incest had always been disgusting. Now she found herself desperately craving her brother! She watched her brother's ass thrust over and over as her sister's feet bounced off of it. She could hear them talking.
"Ohhh God Jeff, I love it when you're inside me." Amy purred as her brother's long organ glided in and out of her vagina. Bonnie knew exactly how she felt.
"I really wanna suck your dick." Amy said, "let's do the 69!" He pulled his cock out of his baby sister and lay on his back beside her. His hard penis was standing straight up, and she grabbed it eagerly as she swung her leg over his head. Her mouth immediately engulfed his cock as he grabbed her ass and forced her pussy down on his face. He licked her tasty pussy, sliding his tongue as far inside as he could. "Mmmmph!" she moaned, her lips gliding expertly up and down his shaft. Jeff spread her ass cheeks, exposing her asshole to him as he sucked her lips into his mouth. He buried his nose right in her ass, licking at the lips that were in his mouth as her own mouth continued to manipulate his penis.
Bonnie had a great view of her sister's head bobbing up and down on her brother's cock. She found herself more jealous than ever, wishing that it was her who had the pleasure of Jeff's penis in her mouth. She had no idea that at that very second, Jeff was licking up the skin between Amy's vagina and her anus. Ass play was a new thing for Bonnie - she had always considered it too gross. If she only knew just how far her siblings went!
His tongue trailed a circle around Amy's asshole. Her heart was pounding in anticipation; she wasn't missing a beat with her blowjob though. He forced his tongue into her tight anus. "Mmmmph..." she moaned around his cock. He spread her ass wide, driving his tongue in and out of her dirty hole. Suddenly, he went down and sucked her clitoris into his mouth. Her orgasm exploded, and she pulled his dick out of her mouth. "Ohhhhhh fuuuuck!" she moaned, rubbing her pussy on his face. Her hand was squeezing his hard penis as she came violently for the millionth time that night. She was gasping for breath, as he just would not release her clit!
Bonnie was so wet watching this. She tried not to finger her pussy. She just wanted to enjoy the show, and try and get her brother later.
"Fuck me up the ass, Jeff." Amy said, still stroking his cock. Bonnie's jaw dropped. What?
Amy let Jeff get out from underneath her, remaining on her hands and knees. He grabbed the jar of Vaseline that was beside the bed (she had it there so she could keep practicing). She loved his cock. She loved everything about it. She loved it in her hand, she loved it in her mouth, she loved it in her ass, and she loved it in her pussy. He coated his finger with lubricant, kneeling behind his young sister. He placed his finger at the entrance to her asshole. He slipped it inside. "Ohhh..." she moaned. Bonnie could see her wince with pain and pleasure. He coated the entire entrance with Vaseline, wiping more on the head of his member.
Jeff placed his penis against the entrance to Amy's anus. He pushed forward. With some effort, he watched the mushroom head disappear into her asshole, stretching it wide.
