It was not until bedtime that the siblings could be alone together.  Tammy waited a few minutes to allow Sylvester to undress but not put on his pj’s.  She entered their shared bathroom and politely knocked on his door.  However, without waiting for a response, she barged in catching him in his TW’s.© YLeeCoyote

“HEY GET OUT!  I’m not dressed!” he barked angrily.

“Quiet, Sylvester unless you want the ‘rents coming.” Tammy said quietly.  “Beside you’re wearing a lot more then when I saw you starkers prancing about with Nicki this morning.”

Sylvester did quiet down and Tammy continued.  “I just wanted to tell that you have a very attractive body and Jenny concurs.  It was great pleasure and a surprise to see it as you always HIDE yourself.”

“Thanks.” stuttered Sylvester somewhat off balance.

“I trust that you noticed that the world did not come to end because you were exposed nor will it if you do it again even in such an inappropriate place.”  The boy was nervous sensing that his sister wanted something.  He was, of course, right.  “How could you get naked with a strange girl?” she probed.

“Nicki isn’t a strange girl for we know each other from school.”  He paused a bit.  “It just happened.  I don’t know why.” he lied not wanting to admit that she had promised a hand job in return for pushing the swing.  It would be his first from a girl so the offer was irresistible.

Tammy sensed that her brother was lying and called him on it.  “Tell me the truth or I’ll tell the folks.  Dad will surely whip your ass so you can’t sit for a week for running about naked like the photos prove.”

Sylvester turned pale at that.  “Please don’t tell.  She gave me a fantastic hand job to push the swing and I had to get naked for that and stay that way.  Pleeeeese don’t tell.”

“That’s much better.  I’ll be watching you and more naughtiness will earn you a spanking.  Understand?”

“Yes.”  He said somewhat relieved.

“That’s ‘Yes, Miss Tammy.’  Say it.”

“Yes, Miss Tammy.”

“Good.  Now remove your briefs and get into your PJ’s.”  She anticipated his objections for she added “No need to be shy for I saw it all in the bright sunlight.  Not to mention the mess of photos I got.”

Slowly he complied much to her delight.  She made careful note of how red and stripped his bottom was from Jenny’s spanking on top of her switching back at the swing.  She commented on how red it still was and promised she would inspect it daily.  Sylvester sensed that it would not help to object so he kept quiet.  “Now if you lie over my lap I’ll put this nice soothing cream on your hot tail so you’ll sleep better.” she added.

That sounded cool so he complied both to his surprise and her delight.  After lowering his PJ’s, Tammy gently rubbed the soothing cream over her brother’s hot bottom even getting into the crack and down to his taint.  Not surprisingly Sylvester got hard and she noticed.

After he stood up, she suggested that he ‘take care of his big hard problem’ grinning broadly.  Again she had to remind him of how much she saw with her own eyes earlier that day and his normal needs got him to jerk off for her.  She rewarded him with a good hard SLAP on his tail.  Then they both went to bed.

Sylvester was confused while Tammy was delighted how her big brother was getting used to following her suggestions (or were they instructions or perhaps even orders) although some things he would have done anyway.  She was especially happy how nicely he fit over her lap.

It was Thursday when Tammy got the better of Sylvester again.  He was an hour late returning from school.  Since their parents were scheduled to be late that day and they had not told her to stay with a friend because he would also be late she made the assumption that they did not know and guessed why.

“You had a detention today and didn’t tell the folks so Dad wouldn’t spank you.” she said and saw his expression that admitted it all.  “I’ll give you a choice of who spanks you – Dad or me.”  Then she added with a giggle that she would be in her room doing homework.

Sylvester was shocked.  She had him dead to rights.  His supposedly innocent kid sister had him in her talons with a Hobson’s Choice for he knew that Dad would use his belt on his bare ass and possibly even ground him for not telling.  He knew he was trapped.  And worse that she also knew.  There was not any point waiting.  He went to face the music.

Tammy was all smiles and simply asked “What can I do for you dear brother?” when he entered her room.  It hardly to a minute to get to “Strip and get over my lap.”

Sylvester was surprised how easily he obeyed his kid sister.  Somehow the previous weekend of being naked and being spanked made it seem normal to do it again.  He found it was best to put all unpleasant thoughts about nudity out of his mind as he stripped.  Likewise when he obediently got over her lap.  He promised himself that he wouldn’t cry as she started to spank him with her hand.

Over and over she landed hand spanks on his butt which he easily accepted without crying unlike the ones he got from his dad.  It helped that she did not lecture like Dad would have.  Then there was a change.  The pain level changed from easily accepted to intense and much greater.  He reacted vocally.

“Ah.  The hairbrush got your attention, naughty boy.” and then she continued spanking.  It took only a few more spanks for him to realize that she could spank painfully effectively.  He repeated his resolution of before but the pain flooded his brain crushing his resolve.

Then he realized that he was sobbing.  This was not a play spanking.  His kid sister was really giving him a real punishment spanking.  That horrid realization along with more hard whacks pushed him over the edge so that he was shamefully crying like a baby.

She, on the other hand, was extremely proud of herself for having reduced her big shy brother to an obedient, bawling, naked, little boy uncaring of his exposure as she gave him some TLC as he cried on her shoulder and promised to be good.  After while she told him to shower and get ready for dinner.  If he was quick there would be time for some soothing cream treatment.

Tammy watched her brother very carefully after that.  Not surprisingly she caught misdeeds and blackmailed him into accepting her discipline each time.  This was their modus operandi initially.  Of course, Tammy was delighted with her new powerful role.  Surprisingly, Sylvester came to like it as well thus the blackmail element disappeared.  Somehow it did not seem to be as oppressive as parental discipline although truth be told it actually was.
