Becoming My Stepsister’s Submissive Slave — Part 3

She looked straight at me, piercing me with her cold stare as she kept strongly jerking me off, my small dick disappearing in her fist. I was there. I was at the point of no return but she kept on jerking, unrelenting.

If you’re new to the series, please start from the beginning:

It was late in the evening when my stepsister came back home and I rushed to meet her at the door. We sat at the kitchen table, and I poured two glasses of red wine and I started telling her all about the encounter with Rachel.

Gaby was clearly pleased to hear I’d been so eager to admit my wrongs and be supportive of her.

“In time, she will notice other things. Rachel will see that her toxic ex-boyfriend is a different person. If you’ll be an obedient little boy and follow my lessons, that is…”

I blushed and smiled, content with the encouraging signals coming from Rachel, and now also from my stepsister.

“By the way, now is the perfect time for your next lesson,” she said, coming very close to me.

“What is it, sis?” I asked.

“I’m extra horny tonight. Wait for me in the bedroom. Stripped!” she whispered in my ear, the sound of her voice sending shivers down my spine.

I paced in her room, up and down, the tepid air on my naked, shaved body giving me goosebumps. Gabriela’s room was elegantly furnished and decorated. The most prominent elements were the king-size bed, covered in expensive sheets and bedcover, and the walk-in closet that started almost like a regular closet and then opened into a whole small room inside.

At the side of the bed, there was a tripod, like the ones used for camera shootings. I didn’t often wander into her room, and I was surprised to find it there.

“Come here, Ryan. In front of the bed,” my stepsister said as she came in.

She’d been just a couple of minutes in the bathroom, but I felt like I nervously waited there for ages. Gabriela sat at the foot of the bed and I stood by her. She inspected me again, all my body, occasionally brushing my thighs or my chest with her hand, making me shiver.

“You missed a couple of spots, but all in all you’re smooth,” she said. “Doesn’t it feel better?”

I nodded and released a surprised gasp of pleasure as she caressed my scrotum.

“Good. Now, assume the position!”

Going down on my knees, in front of my stepsister, was quickly becoming an automatic reflex, easier and easier each time I did it. At first, it was weird, humiliating but now, I noticed a rush of excitement in it. I gently removed her heels and looked Gaby in the eyes as I started to worship her feet.

Gabriela began unbuttoning her shirt and my eyes eagerly followed her hand.

“You shouldn’t watch what you’re not worthy of. Has Rachel ever allowed you to see her breasts?” she said.

“N-no.”

“Just as I thought,” she responded and left the last three buttons on.

I could see the hint of the ample curve of her generous cleavage and the top of her lacey bra, but not much more.

“Tonight,” she said as she picked up her phone and started recording me savoring her feet, “you are going to learn another one of your duties in serving a woman. The most important one.”

With that, she spread her legs wide. I looked up, between her thighs, and I saw her glistening pussy.

“Given your size, you’ll have to learn how to pleasure a woman with your mouth.”

“But sis…” I tried to say but she immediately pushed her toes in my mouth.

I sucked her beautiful toes, slurping all over until my stepsister guided me to lay down on her bed. She placed her phone on the tripod, facing us, and from a drawer she produced two pairs of hairy, pink handcuffs. Gaby secured my wrists to the sides of the bed and then stood before me.

“Oh, Ryan. It’s so tiny,” she said, looking at my dick.

I moaned and shivered as she touched it. It was the first time a person had ever touched it, other than me. I gasped, seeing my stepsister’s finger caressing my pink engorged head and grazing her fingernail over my tiny pee-hole, slowly. She scooped a generous amount of precum then her finger reached me. I instinctively opened my mouth, allowing Gaby to feed me my own juices.

She watched me savor it with an entranced look. This time she didn’t have to say anything, I simply complied. And you could tell how pleased with this she was. Then, without saying a word, she raised her skirt and got on top of me. I widened my eyes as my stepsister brought her pussy right on top of my face, a breath away from me.

“You will learn how to please me,” she said, gently swaying her pussy in front of me, filling the air with her scent.

“I will?”

“Well, of course. You have to learn how to please your woman,” she said, gently caressing my hair.

“Y-yes sis,” I said doing my best to concentrate, but all my attention was on her pussy.

“Take a deep breath,” Gaby said and lowered her pussy a bit more, almost touching my lips.

I was overwhelmed with a scent both absolutely divine and profoundly animalistic. The scent of pussy. I suddenly felt weak, as if a mysterious force robbed me of all power. Now I knew what I had to serve.

“This is the scent of passion, of love. This is what you’ve never had, and what you’ll never have unless you submit to me,” she said, swaying her pussy, all the breathable air around me completely drenched with her beautiful scent.

I slowly extended my tongue and ran the tip along her pussy lips.

“Good boy!”

With that, my stepsister lowered herself onto me. I was overwhelmed, as my senses swirled and melted together, feasting on her pussy. Everything surprised me; the consistency of her labia and her big clit to the many tastes of her juices.

“Don’t forget that this is about my pleasure, not yours,” she said when I started pushing my hips up in the air.

She reached back and I suddenly felt her cupping my balls, massaging and squeezing them, giving me low but continuous waves of pain.

“From now on,” she said, as she ground her sex on my face, moaning, “you’ll wait for me every night at the door with a glass of wine, then help me undress.”

Gaby was now letting her entire weight fall on my face, grinding against me faster and harder.

“And I’ll tie you to my bed whenever I feel horny. Understood?”

I tried to nod but she kept grinding and guiding my tongue to her pleasure nub. After a while, her manipulations found a rhythm, and I found the waves of pain were mixed with intense pleasure. My crotch was on fire, and my dick was desperately hard, having my mouth being used for my stepsister’s pleasure.

Suddenly, she raised herself, leaving my face drenched in her fluids.

“Looks like I need a little push,” she said, and she reached for one of her drawers.

From there, she pulled out her laptop and went through a couple of folders filled with videos. When she was finally satisfied, she played one.

It showed a woman licking the tip of a massive black cock. The tip glistened with her saliva. After caressing it with her tongue, she plunged the shaft into her mouth. I had time to catch just a few seconds before my stepsister straddled me again, this time with her face away from me, and she started rocking her pussy against my lips and my nose pushing into her asshole while her grip on my balls turned stronger.

“I need this, Ryan,” she moaned.

As I did my best to lick her to completion, I could hear the slurping sounds coming from the movie. It seemed like the actress was sucking that cock like her life depended on it. Her efforts were met by the grunts of the man.

My stepsister moved her fingers on her engorged clit and started rubbing and pinching it furiously. She started breathing more heavily, grunting and panting, and even if I didn’t know what a female orgasm looked like, I could tell she was close. She trembled more and more, as her moans grew higher. Her pussy was spasming harder, and harder.

“Fuck! God! Yes! Yes!” she cried out, her grip tightening to the extreme on my balls as I felt her pussy gushing and filling my mouth.

She continued to cum, pushing her pussy hard on my mouth, pressing my face down with her weight as her pleasure hole opened up and she started screaming.

“Swallow it all!” she commanded, grabbing me by the hair and pushing my face deeper into her holes while her other hand still gripped my balls.

I continued to clean her fluids, sucking, lapping and even sticking my tongue deep inside her until she was finally satisfied. Gaby pulled away from my mouth and lay beside me, breathing heavily.

She traced her finger along my jawline and then put it in my mouth.

“Here, you don’t want to waste any of it,” she said as I started licking her finger clean of her cum.

I could finally take a moment to appreciate her sweet taste.

“I’m so proud of you, Ryan! You took all that in. Aren’t you happy?”

Her smile was warm, and she was even praising me while cuddling me, and caressing my hair and my face.

I lay there, still overwhelmed by the experience of licking my stepsister’s sex, excited as I’d never been while she kept covering me in affection.

“Yes,” I replied.

“Look at your little dick,” she giggled, pointing at my desperately trembling erection, a continuous stream of precum going down its short length. “He’s so proud too!”

I giggled with her too, as I purely enjoyed the moment, and this caused me to become even harder. Yes, she loved reminding me of my inferior status, but I was exploring now just how deeply it aroused me, and on the other hand, I had just made her cum, despite everything. I felt a rush of masculine pride, so I got bold and I kissed her. After a moment, she reciprocated, her hands running all over my smooth, shaved body, going up my back, running down my legs, and then cupping my balls again.

It was the first time in my life my body was being caressed and teased. I let out a high-pitched moan and instinctively, I tried to move, to touch her, but my arms were still cuffed, widespread at the sides of the bed.

“Now that you’ve made cum,” she said, circling my nipples with her tongue, “You deserve a reward”.

“Oh yes, sis. Please, c-can I cum?” I asked, in desperate need of release.

She sensually bit my nipple, tapping the tip of my cock.

“No!” she said, looking up at me.

My dick squeezed out another drop of precum.

“Last time,” she said, laying back, her face next to my dick, “You came without permission all over my feet.”

She took my testicles in her hand again, fondling them while I bit my lip from the pain.

“You will not cum tonight,” she said, pinching the tip of my erection.

Her words sounded like the strike of a bell, one that declared defeat.

“But if you learn to hold your load,” she said, and to my disbelief, she began stroking my dick with her thumb and index finger, “We might still have some fun. I want you to stop me when you’re close.”

I tried to protest but my dick radiated an unbelievable pleasure: my orgasm was building up fast.

“S-sis… I’m close, I’m…”

She stroke my dick one last time then let go of it. We both looked at it shake for interminable moments.

“Good. Now I want you to cool down and then we will resume.”

I barely resisted one assault and the porno on her laptop was very distracting.

“All right, let’s go,” she said and resumed gently stroking me.

I panted and grunted as she rubbed my dick with just two fingers.

“Don’t you dare cum. You don’t want to hear the punishment waiting for you if that happens.”

“Stop!” I said as I was approaching the point of no return.

“Already? It’s been, what, ten seconds?”

She stopped and had a long, disappointed sigh.

“Now breathe, and we’ll continue.”

She edged me again, and again for what seemed like an eternity. I lost count after seven attempts, my brain turning into mush. My lucidity was fading, I stopped struggling against the handcuffs and just let my stepsister edge me, biting my tongue and trying to breathe hard while she pinched my dick and fondled my balls to make me cool down.

“Contrary to all expectations, it seems, you’re being a good boy now. One last edge. Are you ready? Try giving up right at the edge this time”.

I nodded my head, a scared look on my face as she started to jerk me off now with her whole hand. On the laptop screen, the movie showed a close-up of a big black dick being stroked and my stepsister started imitating the same movements, going hard and fast.

Soon, I felt that familiar I’d been fighting all night and I tensed all the muscles in my body, trying to resist.

“Stop! Please! Stop!” I exclaimed but she didn’t stop.

She looked straight at me, piercing me with her cold stare as she kept strongly jerking me off, my small dick disappearing in her fist. I was there. I was at the point of no return but she kept on jerking, unrelenting.

“Sto-”

I crossed the line before I could even finish and my stepsister quickly removed her hand from my dick. The wave of my orgasm came and I found no stimulation at all, nothing.

“No! God! No!” I cried out as I humped the air desperately while dribbles of cum spurted from my spasming dick.

“This, Ryan, is a ruined orgasm,” Gabriela said, with a huge grin on her face.

The biggest orgasm of my life had just been destroyed right in front of my eyes. I started to tear up a bit, as a sense of shame got over me.

“It’s the punishment for disobedient little boys like you,” she said tracing her finger on my belly, all over my load. “You’re never cumming against my will. Understood?”

I nodded, a couple of tears running down my face.

“Good boy,” she said, scooping up my cum with her fingers and bringing it to my lips.

Perfectly aware of what I had to do, I opened my lips and put my tongue out. My stepsister let my cum dribble down my tongue.

“Swallow it,” she said.

I obediently closed my mouth and swallowed my semen. I was so horny I could’ve done anything for her.

Standing up, she opened a drawer and took a pair of panties, then sat back on the bed and helped me put them on.

“From now on, you’ll have to make up for every mistake you make,” she said as I arched my back and lifted my hips, allowing her to fit the panties properly on me. “You will do it for Rachel.”

The panties were small, with a low waist cut, made of see-through white lace and white satin to cover the crotch. I immediately stained them with my dicke still coated in my cum.

“If you want me to ever touch you again, you’ll wear these panties for the rest of the week.”

“You mean at home?”

“I mean everywhere.”
