I flew home from school. I was lucky I didn’t get a ticket. All I’d been thinking about all day was what Shannon was going to do to me when I got home.
She wasn’t downstairs so I went upstairs and saw the light on in her room. I quickly went to my room and ditched my clothes. Then I knelt in front of her door and knocked.
She opened the door and I gasped. She wore matching black panties and bra and black high heels. It wasn’t latex dominatrix gear but it was the closest she could find and she looked absolutely gorgeous!
“Come on! I’ve really got to pee.”
She grabbed my ear and dragged me down the hall.
She took off her panties and we got into the tub again. She’d obviously been waiting for me to do this.
I eagerly opened my mouth and accepted my sister’s hot urine. I’d been thinking about this humiliating chore all day too.
Hardly any of it ran down my chin this time and all I had to do was wash my face when she was finished.
Then Shannon led me back to her room and told me to lay down on the bed face down.
While I was climbing up on the bed I saw some things she had lined up on the bedside table. My hard dick spasmed in fear and anticipation.
Shannon went to work tying my wrists and ankles to the posts of her bed. Then she stopped to admire her work, running her hand up and down my naked back.
“Big strong man. All tied up and at his little sister’s mercy.” She mused. “Well, let’s get started, Stevie!”
She picked up a ping-pong paddle off the table and swatted me on the butt with it. It hurt but it wasn’t that bad. Of course any spanking would hurt bad if it went on long enough as she’d proved yesterday but she quickly got bored with the ping-pong paddle.
She stopped and pinched my ass. “Your cute little butt’s turning a pretty shade of pink but I can tell this isn’t hurting you much, Stevie. Let’s move on, shall we?”
“Yes Mistress.” I sighed.
Next she picked up one of her shoes. Not the high heels but one of her usual sneakers. She smacked my already slightly paddled butt and I gasped with pain.
“Now that’s more like it, big brother!”
She paddled me with the shoe for a while. It was really starting to hurt. Tears filled my eyes and I squirmed around and every time I gave a yelp of pain she giggled.
“Okay, that’s enough of that. Let’s get serious here.”
She put down the shoe and picked up a thin, springy branch she must have gotten off the tree out back.
It whizzed through the air and cracked against my tender buttocks. I screamed.
“Ooh-hoo-hoo! I just came, Stevie! Your screams are such a turn on! I want more!!”
She started to whip my butt, back, and legs. I did scream a lot. And begged her to stop. But of course she didn’t stop until she was satisfied.
“Mmmmm that was fun! Moving right along…” She picked up a belt. I was pretty sure it was mine.
“Please Mistress! No more!”
She only giggled and whipped me across the ass with the thick belt. I screamed louder than ever. My ass was already so sore and the belt was a whole new and terrible sensation.
Shannon continued to hit me with the belt. Luckily she seemed to realize that I couldn’t take much more so she didn’t do it for very long. Still I could feel a fresh painful set of welts on my back, butt, and legs.
“Just one more to go, slave. You’re doing great!”
She picked up her jump rope. It was the kind where the rope is a thin rubber tube. I groaned. She giggled.
She whipped me across the shoulders and I screamed long and loud into the pillow.
She pulled the pillow out from under my head. “I want to hear those screams, big brother.”
She whipped me and whipped me. I screamed and begged and cried. Finally she stopped, out of breath.
“Man! I got really carried away! I just love the way you scream and writhe around and are completely helpless while I hurt you! God, I need a picture of this!”
She went to her desk and grabbed her camera then clicked several pictures of my ravaged back side.
She came around the side of the bed and untied my left hand. She guided it between her legs.
“Feel how wet that got me, Stevie!”
Her panties were soaked. I knew she’d cum a few times while she whipped me but I had no idea how many.
She reached under me and grabbed my raging hard-on.
“Ooh hoo! And I see it turned you on just as much!”
It was true. I was in agony but the ordeal had made me horny as hell and dying for my sister to fuck me!
She untied me and told me to stand up.
She picked up the belt again. Oh shit.
“Now don’t you move.”
“Yes Mistress.”
I stood with my arms at my sides as she whipped my chest and shoulders. It hurt like hell and I had to use all my will power not to cringe away from her blows.
Then she raised the belt and brought it down hard on my up thrust dick.
I screamed and leaned over, grabbing my abused cock.
“I told! You not! To move! Dumb-ass slave!” She punctuated each word with a hard blow against my back as I fell to my knees still protecting my dick.
She whipped me down on my knees for another minute then walked around in front of me.
She stood there silently and I realized what she wanted. I leaned forward and kissed her shoes.
“Thank you for disciplining me, Mistress.”
She got me her homework and sent me to my room. I had a lot of difficulty finding a comfortable position sitting or laying. I had a hell of a time at dinner with mom sitting on the hard chair and trying to act normal. Shannon acted unusually cheerful at dinner. Of course I knew why.
A while after dinner she stepped into my room and told me to get on my knees. She slid down her shorts and black panties(still the same ones) and pissed in my mouth. I didn’t spill a drop this time. She left without a word.
She did that again during the evening and once more before bed. She wasn’t even using the toilet anymore! Tomorrow was Saturday and I just knew she’d be pissing in my mouth all day long. The idea was thrilling and terrifying.
That night I waited for her naked on the bed feeling every ache in my back and ass against the sheets. It had been an incredible experience but I hoped she realized I couldn’t take that kind of punishment all the time.
Shannon slipped in wearing only her dominatrix getup again.
“Hello Mistress.”
“How’s the back, big brother?”
“It hurts.”
“Aw, poor baby. Lemmee see.”
I turned on my side to give her a view of my back.
“Oh wow that’s hot!” She gasped, tracing welts with her fingers, awakening new fire in them. Then she grabbed my shoulder and pulled me onto my back. “God I’m so fucking horny!”
She tied my wrists above me again and also tied my feet just like she‘d tied me to her bed only face up this time.
She dropped her panties and crawled up on top of me. She immediately slid back onto my dick and started fucking me. No foreplay this time.
Then just as it was getting really hot she got off my dick. She stood and shoved her dripping cunt in my face.
“Lick, slave!!”
I was caught up in a haze of lust and felt like I needed to cum more than I needed my next breath. She had to smack me on the head before I obeyed.
My sadistic sister got off to three orgasms on my tongue then she climbed off the bed.
“Mmm, that was fantastic! See you tomorrow, slaveboy.”
“Mistress! Please!” I yelped.
She giggled and turned back toward me. “No, sorry. You won’t be cumming tonight, Stevie. But I’m not completely heartless.”She grabbed the black panties off the floor and pulled them over my head, positioning the front patch right over my nose.
“There ya go!”
She’d been wearing those all day, including when she whipped me, and they were saturated with her musky scent. Smelling them all night without being able to get off would be torture!
She kissed me on the cheek. “Nighty night.” And she was gone.
That night was pure hell. I hadn’t cum for twenty-four hours. That was a pretty long time for me but with my sexy, sadistic sister teasing and torturing me it was unbearable. And I had to spend the entire night tied to my bed inhaling the extraordinary scent of her pussy. I didn’t sleep a wink.
Finally in the morning Shannon came back. She was wearing a nightgown and looked like she‘d had a good night‘s sleep.
“Mistress, please! Please!!” Was the first thing I gasped.
She giggled and patted me on the head. “Your begging is so cute, Stevie!”
She undressed and took the panties off my head. Then she climbed up on the bed, positioning her crotch over my mouth. I knew what was coming of course.
“Open up.”
While Shannon peed in my mouth I realized I had to pee pretty bad myself. But even more than that I needed to cum!
She sat down on my stomach and leaned forward with her elbows on my chest and her chin in her hands looking all cute and innocent. “Gee, I guess you reeeeeaaaaally want to cum by now huh, Stevie?”
Her fantastic little butt bumped against my dick.
“Yes Mistress! Yes please!”
She giggled. “Alright. I guess you’ve been a good little slave. Just remember it‘s a privilege granted to you by your Mistress.”
“Yes Mistress! Thank you! Thank you!” I sobbed.
She untied me and then told me to stand up and jerk off. “Put on a show for me.” I’d wanted her to fuck me but I was so damn horny right now I really didn’t care!
I stood and started pulling my dick faster and harder than ever. It wouldn’t take more than a second. Shannon crawled up and got comfortable against the pillows.
“Don’t cum too quick. Make it last. Squeeze it!”
Shannon made me perform for what felt like hours but it was actually only a few minutes. Then she told me catch all my cum in my hand and lick it up. I came harder than I ever had in my life. My whole body felt weak and I collapsed onto my knees but I still managed to catch all my cum and not spill it when I fell.
I obediently licked up the cum in my hand and then crawled to my sister.
“Thank you, thank you, thank you, Mistress!! I’ve never felt anything like that! It was so amazing! I love being your slave! I love it, I love it, I love it! I love you!!!”
I sobbed and kissed her bare feet worshipfully as I blubbered.
She giggled. “Alright, alright, Stevie. Now come up here and lick you little sister’s pussy!”
After I got her off several times she finally let me go to the bathroom and then we showered together again. The water brought new agony to my whipped back.
Then my Mistress allowed me to go back to my room and get a little rest. I wondered what the rest of the day would bring…
I really don't know what to do with this next without making it repetitve. Not sure if it will continue.
