Every night, when my husband fell asleep…
I visited my step-son’s room.
“Honey, daddy is asleep.”
That faint scent, the scent of a man, mixed in with the smell of paint…
My step-son, Billy, 18 and a senior in high school. He wasn’t mine, not my blood. I married his father and Billy was part of the deal.
I didn’t mind, I loved him as my own.
Like most guys his age, he was interested in computer games and girls. Both worried me.
Hobbies, because he’s a lot geekier than other lads.
Girls, because he was such a timid one, I wondered if he would have problems courting them.
But in the evening, in the middle of the night, nobody disturbs us.
It’s our time, private time between a step-mother and her step-son.
Billy was waiting for me as usual. With expectation and nervousness in his eyes.
It’s like that every night.
At first, it was just a good-night kiss. I helped him with his studies and I rewarded him with a gentle peck on the cheek. Somehow that progressed to a gentle brush on his lips. I was shocked at the electricity that sparked inside me when our lips first touched.
I told myself it was because my husband neglected my needs as a woman, that my urges were going out of control.
It was the same tonight. I helped Billy review his work, enjoying the intimate moment we shared, but also to stimulate my intellectual needs. I wasn’t so smart that I attended college in my younger years, but I truly enjoyed academia.
The closer we got to the end of his review, the more tense the air felt in the room.
“I know, honey.”
And at some point, something deeper, an indescribable feeling attached itself to the kiss.
When Billy was close to having his first ejaculation while we kissed, I told myself that I can’t make him worry. It was like a kiss, just like any other night- deep and passionate. But in the heat of the moment, my hand brushed against his shorts and I felt his hardness.
I told myself it was perfectly normal, a simple biological response.
We kissed more after that and for some reason, I felt more comfortable touching his erection.
I told myself it was my role as a responsible mother to educate him in regard to sex too.
My husband, his father, was seldom around. As a step-mother, I have to do anything for his sake.
“Lets begin your extra study session.”
* * *
I was sitting on his desk chair, Billy was standing there prone, with his shorts down between his legs.
One two, one two…
Our bodies were sinfully close. My words were barely a whisper, as if we were sharing a conspiracy.
“One two, one two. That’s right honey, follow the rhythm of my words.”
I set a cadence with my whispers, encouraging him to stroke his cock to the rhythm of my honeyed words.
At first, I made him do it slowly without rushing. And at times, I teased him and make him quicken the pace.
“Very good, Billy, you’re doing a great job.”
We work as a team every night- encourage his masturbatory needs. But I forbade him from doing it without me.
Billy doesn’t do this with anyone else.
It was embarrassing for a man to be watched while he masturbated. I got so close and personal that the shared burden gave me a sense of dominance.
I just sat there, beside him as he ran his hand up and down his hard, vigorous cock.
Against my better judgement, my body, my pussy ached with need, watching my step-son performing such an intimate act. The room filled with his odor. So thick and pungent, it went right to my brain.
However, there was a rule.
“Okay then… stop now.”
Billy clamped his hand down over his cock like a vise. My breath quickened as his fingers clenched painfully against his urethra, preventing the torrent of release he so desired.
With just one word from his mother, he obeyed. Even when mired in pleasure. His big, beautiful cock was angry and congested with blood. Engorged to the point of bursting.
He listened, despite the fact that if he simply ignored me, he could experience the most intense climax.
His body shook and quivered, desperate for the release he so deliciously denied himself.
“Are you okay?”
Billy nodded, paralysed with need.
“Y-you told me to stop, so… So I held it in.”
He denied his primitive need, his body screaming in agony… All for me.
“You’re doing well, Billy,” I purred, pulling his agonised face against my bosom.
God, it made me want to give him the release he needed, but this was to educate him.
This time, Billy laid back on his bed, and I wrap my fingers around his turgid shaft. I took a moment to savour the moment, to feel his heat against my palm. I tell myself it is for his well being.
I didn’t pump.
“You know what to do, honey.”
Billy nodded, and he arcs his hips into my slovenly hand. A drop of precum beaded at the tip, spilling out and leaking down his shaft, coating my fingers.
I moaned inwardly at the slopping wet friction of his cock fucking my hand. Billy’s face was tense with effort, his ass muscles engaging and relaxing with the movement. His leg muscles must’ve been on fire with exertion, but still he doesn’t stop.
“J-Julie, I’m going to-”
I emulated his earlier action, digging my finger tight against his urethra, denying him his orgasm. His face was taut with anguish, but he still didn’t disobey me.
His father was a failure of a man. He cared for nothing but money. He worked from day until night, eat and sleep. He neglected my needs as a woman. I will not let Billy become a useless lover.
For what seemed like forever, I brought him close to the edge. His cock bloomed into a deep, angry red. It was so hard, you wouldn’t think it was a part of him anymore. Slick oil of his own desire leaked all over his cock, glistening in the bedroom light.
“You’re so amazing, Billy.”
His face was both anguish and happiness. Happy that he pleased me.
As a wo man, a horny woman, I can only imagine how painful it was to deny a man at his age, a man at his sexual peak, his need to cum.
“I counted Julie, I did it 15 times today,” he gasped. “I know it makes you happy, so I did my best.”
God, his devotion to me was eroding my sense of reasoning.
I’m his step-mother.
When did I start seeing him not as a step-son, but as a man?
My mind fogged with lust.
“Are you okay?” He said, his eyes was full of concern, despite his own pain.
I needed to finish educating him.
I smiled at him, setting his mind at ease. “You did your best honey, I’m proud of you. You deserve a reward.”
I pulled him up on his legs and I drop my knees onto the floor.
I lifted his cock, so thick and heavy with need.
My face was barely inches away, and I could smell his scent. My nostrils flared and my body responded to my son’s own aphrodisiac.
“Let your step-mother take care of everything,” I purred.
I ran my tongue up from the base of his cock, running my tip along the angry veins pushing up against his shaft. He whimpered, a keening noise so sweet, it went straight to my cunt.
My tongue was assaulted with the salty sweet taste of his precum, peppered with a day’s sweat. I lapped it all up, eager to clean his gorgeous cock.
I savored it all.
I tell myself it was to reward my son for becoming a good lover, a considerate lover.
But really, I wanted to worship his cock. I never had one so big and perfect.
More precum leaked out of his cock. It was the sweetest nectar, produced only after inflicting hours of torment on him. It stung my tastebuds, and it made my pussy burn with desire.
It belonged to me.
My lips engorged his crown, slaking his slit with the tip of my tongue. I looked up and his face was tight with need. My heart hammered against my chest. Excitement churned in my stomach at the thought of the lewdness of it all. A step-mother on her knees, servicing her step-son with her slutty mouth.
What would my husband do if he walked in right now?
God, Billy’s scent was overwhelming. I sucked him harder and harder, trying to mimic a pussy with the insides of my mouth.
Billy tried to resist, he really did. His mouth was agape, gasping and keening, and his fingers threaded into my hair instinctively.
Perhaps it was a reflex. A primal need a man succumbs to when his cock, was in a woman’s mouth.
I wasn’t making it easy. I sucked with fervour and desire.
The desire to feel my step-son cum in my mouth.
His hips bucked now, matching the bobbing motion of my mouth going up and down his aching cock. I didn’t think he was aware of it himself.
He groaned out, and a small part of my brain fired up, warning me, demanding me to quiet himself. But a bigger part was in the throes of ecstasy, mesmerised by the promise of his semen.
Cum baby. Cum in my mouth.
It was sudden.
Billy jutted his cock forward, his cock pushed hard against the inner wall of my cheek. At the same time his hands clamped down, pulling my head towards him, not letting me pull away.
“Oh, God, J-Julie..!”
My good boy, overwhelmed, pushed over the edge, cumming inside my mouth.
His cock shuddered, I felt every thrum and tremor. Suddenly, his cock swelled in my mouth. Hot, sticky cum poured into my mouth and down my throat. It was sweet and salty and I swallowed every drop.
It was Billy’s gift to me. Every single delicious drop. I grabbed his ass, pulling him close and sucking his cock like a straw, sucking up the dregs of his milkshake.
He shuddered against me, his cock softened, and still I sucked.
Spent, I let him settle in bed, knowing he will rest well tonight.
I kissed him goodnight, satisfied that for now, Billy belonged to me. Until the day he finds his love, he was mine.
* * *
“Hello, is Billy here? He said he’ll help me study.”
I was in my shop the next day, and a girl around Billy’s age came in. My home was actually on the second floor of my shop.
“You’re Jenna, right?”
My heart twisted. Jenna was so vibrant and full of vigor. I was a florist and yet her beauty could easily out-shine my most prized flower. Her body was supine and graceful, not like the thick, aged body I possessed. Her hair was silky soft, and I bet her skin was free of blemishes.
“He’s in the back, please go up the stairs.” I smiled.
She nodded and made her way up to my home. Even her movements were gentle and light.
I wondered if she was Billy’s girlfriend.
* * *
I shut the shop early.
I made some drinks and brought refreshments to my step-son and his friend. I told myself I was simply being a good host. As I approached his bedroom door, I noticed it was slightly ajar. Light spilled from the gap, leaving an ominous slice of light against the wall.
Walk in, put the refreshments down and leave. Simple.
But my heart pounded hard against my ribcage. I heard laughter and giggles and I could tell at once that they were enjoying each others company.
I couldn’t push the door open and see for myself.
* * *
The sun was setting by the time Jenna left. She was so perfect and polite and petite. Billy gave me a hug from behind and complimented on how studious Jenna was.
“Honey, I think we should stop our ‘lessons’.”
“What? Why?” Billy asked, his eyes went wide.
Because you’re ready now, ready to fuck girls your age.
“Is it because I didn’t study hard enough? I can do better!”
Maybe he was thinking of Jenna when I did those things with him. She was beautiful, so much better than a shameful woman like me.
“I think… I think you should be doing those things with a girlfriend. You must’ve hated doing it with your step-mother, no?”
“No! I only want study sessions with you!”
“There’s nothing more I can teach you…” I said, my throat feeling like it was laced with glass. I did it with my hand… I did it with my mouth…
There was one more thing…
“What about Jenna?”
“What about her? Did she displease you? I’ll stop seeing her Julie, please, just don’t shut me out.”
His eyes were filled with hurt, an emotion more intense than any torment I have ever inflicted upon him.
“We have one more lesson,” my mouth moved on its own. “I’m going for a wash. If you don’t want it, please lock your door.”
“Do you mean-”
I left him there in the kitchen.
I rinsed off, scrubbing my body clean under the torrent of hot water under the shower. My mind was a haze. I admit that I have fantasized about this moment, about claiming my step-son’s virginity.
But that was all it was- a fantasy.
Up until now, I was simply teaching Billy how to become a man, not to enjoy his body.
My hand drifted between my legs and I felt the sopping wet heat of my cunt soaking my fingers. Despite the water washing over me, I felt how much I needed it.
I shouldn’t as a step-mother. As a woman, I found it almost impossible to resist.
I changed into casual clothes. I considered putting on something sexy, lingerie that my husband used to want me to wear for him. But that felt presumptuous. There was no guarantee that he will want me.
I walked to his bedroom like I have done so a thousand times. But this time it felt different. It felt long and arduous, every step I took was closer to an outcome I may regret.
My hand shook as I held onto the door handle.
I didn’t realise how long I was holding my breath for until I turned the handle, not sure if I was grateful or not for it to yield to me.
He didn’t lock his door… That must mean he accepted me, right?
Billy was there, standing in the middle of the room, his face burned red.
There were no words for what I was about to do.
I simply walked up to him, to my boy, and cradled his face in my hands.
“Julie? What are you-”
I’m sorry, honey, please forgive me. I can’t control herself any longer.
I pushed my lips against his in a bruising kiss. Not one a step-mother would give her step-son, but a woman to her lover.
Billy responded feverishly, snaking his tongue past my lips, prying past my teeth before finding his prize. I tasted his sweet saliva as his tongue caressed mine. I pushed back with equal fervour, not wanting to be outdone by a man more than half my age. His hands were aggressive, grabbing and pawing my sweatshirt, making me moan into his mouth as his fingers found my nipples.
I was unreasonably sensitive, my skin tight with anticipation and desire, not just from his kiss, but from our many sessions together. Many times after I left his room, I had to settle for my fingers, teasing my clit and surreptitiously fucking my cunt beside my husband in bed, denying myself the luxury to cry out my own step-son’s name.
Billy noticed the effect he had on me and he grinned. “You’re not wearing a bra.”
“S-shut up,” I replied. We might be making love, but I was still his guardian.
His hands snaked under my top as his lips found mine again. He took a moment to examine, to fondle and heft my breasts. A pang of embarrassment shot through me like a bolt of lightning, realising that my body wasn’t as spritely as Jenna’s.
“What’s wrong, Mom?”
“Nothing. Was just thinking how old and haggard I am.”
“Julie,” he breathed. “You’re beautiful. No one else can compare to you.”
“You’re just saying that,” I replied, but I felt my heart soaring.
“Let me.” He grabbed the sides of my sweatshirt and hoisted it over my head. I heard him gasp, and when I saw his face, his mouth was agape.
“You really are beautiful, Julie.”
I felt my face flush. Billy's eyes were glazed over with lust. I haven’t had a man look at my body like that since forever. He was positively devouring me with his eyes, as if he was committing every minute detail to memory.
“May I?” He asked.
I nodded, and he cupped my breasts again, both hands on the girls. I groaned at his touch and goosebumps bloomed across my chest.
Taking a more active approach, Billy leaned forward and sucked on my nipple. I cried out, not used to the sensation. I squirmed against him as his tongue circled my hardened nub, gasping as his tongue ran circles around the leathery flesh around my nipple.
Then he sucked and sucked, as if on instinct.
“Honey, nothing will come out,” I giggled, realising that he was trying to nurse me. He carried on sucking, while his other hand fondled my other breast, but the look in his eyes told me he was disappointed.
Billy was wearing a pair of shorts and his cock was tenting hard against me. In fact, the head was pushing against me. My pussy ached with need, getting creamed with my own juices as the thought of his cock was right against me, merely separated by a few thin pieces of fabric.
“Julie…” he groaned, flexing his hips, instinctively trying to claim his prize.
“Do you want to see me naked?” I rasped.
He nodded eagerly, and I chuckled to myself. I walked over to his bed and he watched me.
“Take off your shorts.”
He obeyed and I couldn’t help but admire his beautiful, rock hard cock. God, it was so big, so obscene. It was massively out of proportion to his frame. My pussy twinged with need as I eyed up his size. I saw it many times now, but I was still in awe of its sheer size. It was long, curved and thick.
It would surely stretch out any woman’s pussy.
I licked my lips at the thought of the delicious pain it would make me feel as it plunged into my depths.
I hooked my fingers over the waistband of my pants and eased them down over my thick hips. A string of my own nectar came away with it. God, I was so fucking wet.
I sat on Billy’s bed. Like a shameless harlot, I opened my legs wide. Billy came over and gazed down at my core.
“C-can I touch it?” He asked.
His face was dangerously close to my inflamed lips. He was so close, I could feel his breath over me. I felt my pussy twitch under his gaze. What will he do? Just observe and satiate his intellectual curiosity? Will he touch me? Or would he…
Without warning, Billy mashed his face against my pussy. Immediately, I groaned out, my heels digging deep into his mattress.
“Oh god!” I cried out.
But Billy didn’t respond. He was busy running his tongue up and down my slit, stabbing with his tongue as if he was fucking me with it. Now and then, his tongue would graze my clit and I would buck my hips to meet his mouth. But he was oh so clumsy. He was too inexperienced to know how to please a woman in that way.
In a way, found his lack of experience hot. More than likely, his step-mother’s cunt was the first he tasted.
After a few minutes of his enthusiastic lapping, he finally came up for air.
“You okay, honey?”
“That was amazing, Julie.”
“You sure it tastes okay?” I was glad to have showered, but I still worried that my pussy would taste repulsive to him.
It was as if he read my mind. “It tastes… Nothing I ever tasted before. But I like it, I like your taste.”
He dived right back in and I cried out again against his tongue. God, he was going to become such a considerate lover. My fingers snaked through his spikey hair, gently guiding his mouth closer and closer to my clit.
“That’s it Billy, that’s it,” I cooed. Billy understood, but he was still eager to lap up my juices. His tongue licked and swirled, travelling up until it lashed my aching nub.
“Fuck!” I cursed, and I realized that it was the first time I swore openly around my step-son. I looked down past my sweat shone breasts, right down at him, but he was entranced with the task at hand.
Then he wrapped mouth his mouth around my clit. He sucked and swirled, much like what he did with my nipples. I squirmed and writhed, clenching my thick thighs around his face. It only spurred him on, a part of him realized that he was building me up to something, but he didn’t know what yet, but he just knew he couldn’t stop.
He didn’t stop. And that all too familiar feeling, a feeling I haven’t felt since my husband wanted to make love to me came rushing over me, like a tidal wave of euphoria threatening to push me over.
And over, I fell.
I cried out, I cursed, I called out Billy’s name. My entire body tensed and wracked with an intense pleasure so sublime, every fibre of my being screamed out. My fingers dug hard into my step-son’s scalp, beyond caring if I’d hurt him or not. I didn’t want him to fucking stop. I needed this, I needed to cum. And I did, my hips rocking as my orgasm pulsed through me.
Billy didn’t stop sucking my clit, and he turned it down into gentle licks as I released him from my grip, my storm of an orgasm subsiding as quickly as it came.
I collapsed back into Billy’s bed, no doubt soaking his sheets in my sweat. I covered my eyes with one forearm, cloaking myself in darkness and feeling the sweat on my forehead, wetting my arm. The room was quiet save for my heaving breaths.
Then I felt the bed shift under me.
I pulled my arm away and looked down.
Billy crawled up my body.
His legs pried open mine.
His hand was wrapped around his cock now, his fingers barely closing over his girth. Instinctively, he slapped my soaking wet pussy with his cock, which sounded like a log falling down on a puddle. My body shuddered again- It’s been a while since I had cock rubbing up against my pussy.
So polite, still so polite.
“Take it honey, you want to fuck me, you just take it.”
It was like a switch flipped in his head.
He guided his bulbous head and aimed it at my core. And then he pushed inside me.
I moaned, my inflamed lips yielded to his cock, spreading open all too easily. I was sopping wet with need, but I still had to grit my teeth against his size.
“Oh God…” He cried out.
“Does it feel good, baby?”
“It’s so hot and tight, it's nothing like touching myself.”
His cock slid a few inches further. I thanked him to not just shove it in all the way, although the idea gave me a dark, twisted thrill. I mewled as his cock snaked further inside me.
“So good baby, keep going,” I grunted.
Billy obliged. He pushed on until the entirety of his cock bottomed out completely inside me. I felt the tip of his cock kissing the entrance of my womb.
“F-fuck…” I hissed. We were so close now that his face was barely inches from mine. His lips, nose and chin were coated in my own juices.
I arched forward and kissed him, wrapping my arms behind his head.
I tasted the tangy sweetness of my essence as his tongue pushed into my mouth with renewed vigor.
Then he started easing his cock in and out of me.
I felt the inner walls of my pussy stretch and milk his cock as he sawed in and out, setting off every nerve inside me like an erotic firework.
“Oh God..!” I cried out. I embraced my step-son, clinging tight against the feeling that I so desperately missed. No, even more than that. Billy’s father was never this obscenely big.
Billy’s tempo increased. He kept rocking until he was fucking hard.
“Honey,” I purred, “slow down, no need to rush.”
But Billy couldn’t hear me. He was drunk on the pleasures he could only experience from a woman’s body. His step-mother’s body.
His very core, his biological imperative was being fulfilled. I braced myself, knowing what was coming.
I licked my lips, relishing it.
Billy fucked harder and harder, words no longer coming out of his mouth, replaced with nothing but feral grunts and moans. He was breathing hard, and I could smell his breath, my juices on his lips and the desperate need for primal release.
I felt his cock twitch once, twice inside me.
“J-Julie…” his voice choked out.
“Cum baby, cum inside me.”
Billy cried out, and I felt his cock balloon against the inner walls of my pussy.
I locked my legs around him, my heels digging into his ass, and I pulled him taut against me.
Oh God, it’s coming! I’m cumming!
Billy’s fingers dug into the sides of my hips, and he lurched forward, driving his cock deep inside me. He howled and his cock spasmed, and I felt load after load of molten hot cum blasting into my pussy.
I squealed, and I grabbed his face and desperately kissed him, claiming his mouth. His orgasm triggered my own and I sobbed into his mouth, my body tensing and flexing as I climaxed. The inner walls of my pussy kept milking him over and over, drawing as much of his virile cum deep into me as possible.
Spent, I collapsed back and Billy fell on top of me. We were a heap of sweating and exertion.
“That was amazing.”
I stroked his hair. I couldn’t say anything. He was using my breasts as a pillow and one hand was casually caressing my sweat-shone tit. No words could describe not only euphoria, but a strange sense of warmth and fulfilment I experienced right then.
I made love to my darling son.
“I love you, Julie.”
“I love you too, honey.”
I knew it wouldn’t last forever. Eventually he’ll graduate and head off to college, more than likely meet a beautiful girl to make love to.
Until then, his heart and his cock belonged to me.
