Stepdaughter Bondage Day

My stepdaughter Brook (F19) and I had already had a full morning. She'd been beaten with her new riding crop, pissed on, and throat fucked hard. None of that stopped her from wanting more. At my request, she got me another full glass of water and returned to her room. I took a big sip and put it down as I started setting up some restraints for her.

She still has a bunk bed, so I used the railing on the top bunk to secure her wrists. I used the spreader bar to secure her legs, strapping them to the base of her bed. She was very compliant and very excited each time I tightened a restraint in place. "You're mine now." I made sure to make my voice grumble low as I smiled. I picked up the flogger. We hadn't used that yet. I dragged the tails of the flogger across her face and tits before lightly flicking it against her tits with a sweet crack.

"Mmf! Thank you Master!" She said, barely opening her mouth.

"What's that? I didn't hear you?" I said, bringing the flogger down across her tits harder, instantly seeing welts beginning.

"Fuck! Thank you Master!" She screamed. I checked to make sure she still remembered the safe word before swatting her ass hard. I looked at her face and saw tears in her eyes. I used the safe word in the form of a question, and she just shook her head no, signaling she was still good to go. I flogged her ass, legs, and tits until they were welted and glowing red before swinging right onto her pussy with a little less force. "Jezus fuck!!" She screamed and I rubbed her pussy. It was dripping wet.

"I don't think I heard a thank you. . ." I said, grabbing her ass.

She screamed louder. Clearly, her ass was still in a lot of pain, and the squeeze just made it worse. "Thank you." She whimpered. "Master." She said, breathing heavily.

I ran my hand through her dripping cunt and smeared her juices all over her asshole, grabbed one of the butt plugs we bought and lubed it up good. "Now you're going to hold this in your ass. . . Don't let it fall out, or you won't be able to sit for a week." I said as I pushed it on and out of her asshole until it all but disappeared. Then I sucked and bit her nipples before putting her nipple clamps on tight. I pushed three fingers into her, feeling the plug through the thin wall between her pussy and ass. I put my hand just above her collar and squeezed as I finger fucked her. "Remember, you have to have permission to cum bitch." I said, licking her face.

She whimpered and shook her head yes, but I could feel her pussy quiver already and pulled my fingers out fast, slapping her clit. "Did you not understand me?!" I said, slapping her pussy again. "I said you don't fucking cum until I give you permission!" I said just before spitting on her face and releasing my grip, watching the blood flow back into her face.

"I understand Master." She said, catching her breath. "I'm sorry Master." She said with a yelp as I smacked her ass hard. "Fuck!" She screamed as her butt plug hit the floor.

"You know you have to be punished now." I said calmly, picking up the flogger once again and hitting her ass over and over again as she screamed bloody murder. I threw the flogger down on the bed, picked up the butt plug, and pushed it in her mouth. "Are you going to drop it again?!" I yelled, pulling it out of her mouth and pushing it back into her ass.

"No. . . I promise, Sir." She said, tears rolling down her cheeks.

I lightly touched her ass and she tried to jump. I felt bad, but I wanted her to have this experience that she so clearly wanted to have. I chugged the rest of my water and started fingering her again. "I'm gonna piss all over your little whore body! Right here!" I yelled, gaging her reaction.

"Please Master, I deserve it!" She moaned as I pulled my fingers out of her cunt and shoved them in her mouth, making her gag. I pulled them out, strings of saliva connected her mouth and my fingers until I grabbed my cock and immediately started pissing on her. Arching my back, I made sure my piss went all over her tits. A little bit more, and it was hitting her right in the face, pouring down her body onto the floor. She opened her mouth wide and swallowed a mouthful just before I finished. "You dirty fucking slut!" I yelled, smacking her piss soaked tits. "Tell me how much of a piss whore you are!"

"I'm YOUR piss whore! Your filthy slut Master! Please! Please fuck me!" She begged.

"You're not going to cum until I tell you, right? And that plug stays IN!" I said, squeezing her tit and slapping her soaking wet cunt.

"I promise, Sir!" She moaned.

I unhooked her restraints and repositioned her bending over. The light hit her back as I positioned myself, and I saw just how beat up she was. I was impressed that she still never used the safe word. I pushed my cock into her slowly at first, to an resounding "Fuck yes, Sir!" Hearing the 'sir' brought me back from feeling bad about how beat up my stepdaughter was, and I grabbed her hair, pulled her head back and started railing her harder and faster.

"Fuck yes! I'm your whore! I'm your nasty little piss slut! Thank you Master!" She screamed as I continued. "Please. . . Let. . . Me. . . Cum!" She begged, her voice shaking.

"Not yet!" I said, completely stopping with my cock buried inside her. I flexed my cock, making it jump inside her.

"Fuck! Please, Sir!" She moaned. I said nothing and didn't move until I heard her breathing regularly again.

"Good girl." I said, pulling my cock all the way out and slamming it back inside her again and again for a while until she started begging again.

"Please! Please! Please!" She pleaded. "Please let me cum Sir!"

"Fine!" I said loudly, acting like I was pissed. Cum bitch!" I yelled.

I barely got the words 'bitch' out before her orgasm started. She shook as much as she could still bound and I felt her cunt grip me tight again and again as she screamed through what seemed like a never-ending orgasm. "I should make you wait more. . . You're getting too used to cumming whenever you want." I said, pulling my cock out of her as well as the butt plug, and shoving it in her mouth. "Now your ass is mine!" I rubbed the head of my cock against her asshole before pulling the butt plug out of her mouth, throwing it aside and pushing myself balls deep into her ass.

"Fuck yes! Fuck my ass! Thank you, Sir!" She screamed. I could tell it was more pain than pleasure at first, but those lines were clearly being blurred. I grabbed her ass cheeks, and she squealed in pain. I had almost forgotten how much I flogged her. I pulled my hands away, held her hips and fucked her ass harder than I ever had before. "Fuck! Fuck! I'm gonna. . . I mean can I. . . Cum?!" She screamed.

I didn't think it was possible from just anal. "You better cum now! Cause I'm gonna fill your ass soon!" I groaned. I was stunned when she started squirting on the floor with my cock pounding into her ass. Every thrust brought a splatter of squirt onto the floor mixed with delicious screams of pain and pleasure. I almost forgot I was about to cum until I felt my cock tense up. "Here comes the load for your ass bitch!" I yelled just as I started shooting deep into her ass.

When I was finished cumming, I pulled out and watched my cum ooze out onto the floor. I unhooked all her restraints, her collar, and her nipple clamps and lay down on the bed. "I don't know if you feel it all now, but that's going to hurt really bad later." I said, softly touching her red, welted back and ass. "Let me give you a cool bath, and we'll get some aloe on you." I said, giving her a sweet kiss.

"Thank you, Daddy." She said, kissing me back just as tenderly. "I really like it rough like that. . . But maybe I should have used the safe word." She smiled, looking at me with her big brown eyes. "But that was still amazing."

"Next time, use the safe word." I scolded her. "You're going to feel this for days." I said, feeling a little bad.

"Mmmmm. It's worth it." She said, looking deep into my eyes. "I like being your slave." She said with a little giggle before I brought her to the bathroom and gave her some much needed aftercare.
