Chapter 4

With that the nurse took her place on the chair. She looked first at Ryan but then turned to Susan. “Susan get yourself over here now! You should have known that Ryan was lying ... you’re his big sister for god sake!”

With Susan back down over the nurse’s naked legs and her bare ass cheeks shining; the nurse tore into her. And with the doctor standing right next to her she too switched from her hand and took up the ruler! As she was beginning to make little cuts on Susan’s ass cheeks she followed the doctor’s lead and pushed two of her fingers into Susan’s dry puckered asshole.

“You see Susan, your ass needs to learn too! This is the proper way to administer a spanking to bad little boys and bad little girls! So what are you Susan ... tell us now!”

“I’m a bad little girl ... yes I am a bad girl! Thank you for my spanking ... I was bad ... I needed this spanking please ... don’t stop ... please!”

Hearing this, the nurse turned and looked at the doctor and they both smile as big as the moon. At that moment the two of them knew that Susan was a special kind of girl ... one that enjoys discipline and needs it all the time! With an approving smile from the doctor; the nurse handed the ruler back to the doctor and then used the fingers from her spanking hand to push into Susan now very wet pussy! Susan began to moan feeling the nurse finger fuck both her asshole and her pussy. After fucking Susan for several minutes ... with her little brother standing there watching her being used by another woman she pushed Susan up and told Ryan to lie across her lap. As Ryan’s bare skin met the bare leg of the nurse ... both of them felt the wetness that had been left by Susan ... juices dripping from her pussy!

The nurse ... now rested ... laid back into little Ryan. She moved through her rough hand spanking and then took up the ruler. Just as the doctor had done the nurse was making sure she too was making those tiny cuts into his butt cheeks ... this time even showing a little blood! Susan’s eyes were as wide as a car head lights seeing her little brother’s butt cheeks bleed red! And as before from the doctor she too shoved fingers ... this time her 3 dry fingers up his little asshole. He was crying wildly from both the spanking and the finger fucking. Ryan was truly in pain and Susan knew it! Her ass was still burning and her asshole was too ... so she knew what Ryan was going through at this moment!

“Nurse don’t stop yet ... let’s see if our little one has any more of his boy cum to share with us today!”

Hearing this from the doctor the nurse stopped with the ruler and just focused on finger fucking her bad little boy. He was beginning to slow down his crying and was now beginning to moan. And moaning he was!

“Ooooh yes ... yes fuck me ... ooh yes please ... yes,” Ryan was now yelling. And with that he was pulled up by the nurse and there he stood with his cock sticking out in front of him. Susan hadn’t even seen the doctor move behind her but before she knew what was happening. The doctor had pushed her to her knees in front of her little brother and his cock was pushed into her mouth. She was taking shot after shot of his cum ... now swallowing it down with each additional shot! No one was forcing her now as she was bobbing up and down on her brother’s still hard cock. She had brought a hand up and was jerking him off at the same time she was sucking him off! Seeing the brother and sister locked in the sexual situation the doctor sat down on the chair behind Ryan and began fucking his asshole again ... much harder this time! Just as she thought ... Ryan quickly began pumping another round of cum into his big sister sucking mouth!

“Just like your mother Ryan ... your big sister has sucked you off and drank down your cum. She learned that from your own mother. Ask her about that tonight ... ask her how much she enjoyed sucking her son’s cock ... just like your big sister is now!”

Susan still had his cock in her mouth as she heard everything that doctor had just shared! She was wondering how her mother would react with her son knowing she had sucked his cock. Of course Susan was thinking all of this as she continued to suck Ryan’s cock in front of the doctor and the nurse.

“Trust me Susan; your family’s sexual secrets are safe with us! Go ahead and get Ryan home. You have a lot to get done with him and your mother tonight!”

The doctor handed Susan the prescription and the ruler as they left the exam room. Neither of them spoke during the entire drive back to their house. Once they got inside Susan told Ryan not to breathe a word of what happened or anything that was said at the doctor’s office today!

As soon as Susan made it to her bedroom she yelled at Ryan and told him to meet her in their bathroom. When he arrived he saw Susan setting naked on the toilet. She told him to strip and lay across her lap. Once he had lain down he heard his big sister begin to pee ... it was so loud come up from the toilet water! Susan began spanking her little brother with her bare hand. She wasn’t spanking his as hard at the doctor or the nurse had spanked her but she was still getting his butt cheeks red! Then she reached over to the sink and grabbed the ruler. With it she went back to laying into him and she too was bringing blood to skin!

“Ooooh stop ... Susan stop please ... your hurting me!” Ryan cried out.

Then following her instructions she pushed two fingers into her brother’s asshole. As quickly as she began finger fucking him he cried out from the spanking and from the fucking.

“Ooooh yes ... yes fuck me ... ooh yes please ... yes,” Ryan was now yelling. “Fuck me ... yes fuck me!” With that Ryan shot a load of cum all over Susan’s legs ... so much so it was dripping onto the floor!
