"Girls.... girls stop, what are you arguing about."

"Nothing Mommy."

"It's something, you don't argue about nothing."

"You wouldn't understand."

"Brittany it would surprise you what I understand, tell me."

"Yeah Britt tell Mommy you're the one with the big mouth supposedly."

"Shut up Jaz your just jealous."

"Girls enough."

Brittany and Jasmine are my twin 18 year old daughters, I know siblings fight with each other but the girls are different. They barely fought with each other growing up, the fighting was generally directed at some other poor person that angered one of them. In the last couple of years even a raised voice between them was unusual.

"Alright Brittany enough tell me what you are arguing about."

"But Mom."

"No buts young lady, what are you two arguing about."

"Greg."

Greg is my 20 year old step son, I married his father Drew ten years ago. Both of us lost our partners in separate accidents several years earlier.

"What did Greg do."

"Nothing Mom," Jasmine says.

"Well then Jasmine why are you arguing about him."

"Ah....well....um...I...I can't tell you, it's too embarrassing."

Both girls are acting very strange, looking at the ground, fidgeting about.

"We're all adults, you know you can tell me anything girls, I'll understand."

I'm starting to feel nervous myself, what could be possibly too embarrassing involving Greg for the girls to tell me. A lot of thoughts are going through my mind and not all of them are nice.

I turn my attention to Brittany, if either of them are going to talk it's her.

"Com 'on Brittany tell me what's going on NOW!"

"Um....ah...we...well...um...we were talking about...um....Greg."

"You were doing more than just talking about Greg."

"Well it was all Jaz's fault, she wouldn't believe me."

"That's because your a liar, there's no way you could swallow ten inches of his cock."

"I could so, your just jealous that you could only swallow six inches."

What the fuck, I can't believe what I'm hearing, my daughters are arguing about how much of there step brothers cock they could swallow.

"Greg's cock...."

"Oh Mom you wouldn't believe how big it is, it's longer than my forearm and it wasn't even hard," Brittany says a hand moving up and down between her elbow and wrist to demonstrate.

"And thick Mom, it's thicker than my arm," Jasmine adds wrapping her fingers around her arm.

"Greg's your...your step brother, you...you can't talk about him like that."

"But Mom it so huge, I've never seen a cock that big before." Jasmine says.

"Me either," Brittany adds.

I'm not naive enough to think the girls haven't seen a cock before, I don't even think they are virgins but Greg, Greg is their step brother.

"Girls you shouldn't be spying on Greg and you definitely shouldn't be thinking about his penis like this."

"Mom we weren't spying," Brittany says.

"Then how did you see his penis then, did he show you?"

"No, no Mom, Greg doesn't even know we've seen his cock," Brittany says.

"How then?"

"A while back I got up early to go to the bathroom, I opened the door to see Greg walking to his room, he only had a towel wrapped around his waist. As he opened his door he removed his towel and I could see his cock," Jasmine said.

"Yeah and she told me so next morning we both got up early, we watched for Greg leaving the bathroom. Again he only wore a towel which he removed as he opened his bedroom door."

From the girls open door your get a clear view of Greg's door which is only a few steps away, with the door slightly ajar they definitely would get a profile view of Greg's body.

"Well girls that's beside the point, you wouldn't like Greg peeking at you so you shouldn't be peeking at him."

"No Mom," they say in unison.

"Right that's it, no more peeking out your door and definitely no more discussing Greg's penis, agreed."

"Yes Mom."

I leave their room stopping briefly outsides Greg's before moving away.

Even though the girls have said they won't look the temptation is still there and knowing human nature temptation will be too strong. I need to confirm what the girls saw and if necessary talk to Greg.

Greg works four days a week having every Tuesday off, he has his morning shower before 5.30am each work day. From my bedroom I can also see Greg's room, tomorrow morning I'll get up early to see for myself what Greg does.

I'm up just before 5.30am, my bedroom is further down the hall from Greg's, I open my door just enough to peer out and wait for Greg to appear. Just as the girls said Greg walks down the hall with a towel wrapped around his waist, as he reaches his door he grabs the handle at the same instance he pulls the towel off, momentarily standing naked in the hall before stepping through the doorway."

"Oh my god," I gasp as the towel is removed, Greg briefly glances up and down the hallway before stepping into his room.

I'm frozen to the spot, the girls were right Greg's cock is huge, if anything they underestimated the size with their measurements, it's a monster cock.

I'm still standing with my door partly ajar when Greg steps back into the hallway, he walks down the hall passing my door dressed for work. I hold my breath as he walks by, there's no indication from him that he's aware of my presence.

Turning around I stare at Drew lying asleep in bed, Drew's cock is a good size but nowhere near the size of his son's. The question is what do I do now, do I tell Drew getting him to talk with Greg or do I deal with it myself.

I climb back into bed beside Drew, my hand sliding between my legs as I think about Greg's cock.

Next morning I'm once more peeking out my door as Greg walks down the hallway, like yesterday as he reaches for the door knob he pulls the towel off. Today he doesn't immediately step into his bedroom, he stands naked for several seconds looking straight ahead before stepping from sight.

As Greg disappears from sight the movement of the girls door catches my attention, I'm not the only one up early.

"I thought we agreed no more peeking at Greg in the morning," I say stepping into the girls bedroom. They are both sitting on Brittany's bed and jump as I open the door stepping in.

"Mom, we weren't, what are you doing up?" Brittany asks.

"What I'm doing doesn't matter, what's important is what you two were doing."

"We got up early to do some homework, I was going to go to the bathroom and saw Greg when I opened the door. Remembering what we promised I quickly closed the bed to wait until he was gone."

"Do you think I was born yesterday Jasmine, get ready for school and we'll discuss your punishment tonight."

"Yes Mom."

"Yes Mom."

Greg is gone when I leave the girls room, I make my way to the kitchen and start preparing breakfast.

After considering my options I decide to deal with Greg directly myself, I'm his mother after all and Drew is going away on the weekend for work next week. On Monday morning I will go to his bedroom after his shower and confront him, basically catch him in the act.

Monday morning I watch Greg perform his normal routine, maybe it's just an unconscious habit and he doesn't realise he's doing it.

As he steps into his room closing the door I step into the hallway walking up to his door, taking a deep breath hoping that this discussions goes smoothly I knock on the door.

"Come in."

Opening the door I step into the room, Greg has his back to me, as I step in he turns around facing me naked.

Standing with his legs shoulder width apart, arms at his side, his cock sways from side to side. Greg is six four, six five with a lean muscular physique, he has short black hair, brown eyes and a permanent five o'clock shadow. But it's none of those features I'm looking at, it's his monster cock that my eyes are locked on and that is causing a tingling sensation between my legs.

"Hi Mom is there something I can help you with?"

I can't speak as I stand admiring his cock.

"Mom what do you want I need to get ready for work."

"Ah...oh yes um...sorry, it's just...well um... it's just that I notice in the mornings after your shower...that um... before you step into your bedroom...well...um...you remove your towel standing naked in the hall."

"I do."

"Um...yes....I've....I've seen you a couple of times when I was up early."

"Sorry I didn't realise, I'll make a point of being in my room in future."

"Thank you I'd hate for your sisters to see your co...penis. Not that there's anything wrong with your penis, it's a lovely penis it just that, well you know they are your sisters."

"Not a problem Mom I completely understand, now I need to get dressed."

"Yes of course Greg, thank you for understanding," with one more glance at his cock I turn and leave.

Greg does change his early morning routine, I check several mornings over the next couple of weeks and each time the towel remains on.

But that's not the only thing that changes, I have become fixated on Greg's cock, I find myself constantly drawn to his crotch, often just staring at it like I'm in a trance. I even find that while having sex with Drew my mind wanders to Greg's cock and I yearn for it to be him fucking me.

Things only become worst several weeks later, it's a Tuesday my laundry day and everyone knows to leave there clothes in the laundry for me to wash, on this particular Tuesday I have none of Greg's clothes. Even though Tuesday is Greg's day off it never crosses my mind as I head to his room, I just want to get his clothes and get the washing done.

I'm so focused on getting his clothes that without thinking I just open the door walking into his bedroom.

My mouth drops open as I freeze to the spot, Greg is lying on his bed looking at his phone naked, his hand stroking his monstrous hard cock. His hand barely covers a quarter of his long cock as it glides up and down his shaft, a thick shaft glistening from a coating of lube.

"What can I do for you Mom?" Greg asks turning his head to look at me, his hand continuing to stroke his cock.

"Come to do washing."

"Oh sorry forgot to put my clothes out, they're in the basket."

"O...Ok," I manage to get out as I slowly shuffle toward the laundry basket my eyes firmly fixed on his cock."

Putting the phone down he picks up a pair of boxers, "You can have these too."

Greg holds them near is cock, he's watching me intently, watching my every movement. He's not going to throw me the boxers or even reach them to me, he wants me to come get them.

Moving near him he continues stroking his cock holding the boxers on the far side, making me reach over it to them. As I do I glance at his phone, 'FUCK' I scream in my head, it's a picture of me in a bikini, Greg is jerking himself off to a picture of me.

Fuck what do I do now, do I drop the washing wrapping both my hands around his thick shaft pumping it, or do I take that big bulbous head in my mouth, or do I just straddle his waist impaling my soaking wet pussy on his gorgeous cock.

Instead of doing any of these reckless, irresponsible thing I take hold of the boxers putting them with the other clothes and leave the room.

"Thanks Mommy," Greg says causing me to stop and turn to look back in his direction. He gives me a big smile then picks up his phone, looking at my picture on to it he strokes his cock faster.

I turn rushing to the laundry.

I'm breathing heavy, my whole body shaking as I stand in the laundry. Putting the clothes in the machine I turn it on. Getting on my tip toes I move to the corner of the machine pressing my pussy against it, I close my eyes remembering the sight of Greg's erect cock as the machines vibrates against my pussy giving me a earth shattering orgasm.

After the washing day encounter Greg also changes, he begins touching me, instead of walking around me he brushes pass me. He places his hands around my waist pressing his body against mine as he moves pass, his cock rubbing against me as he whispers to me 'Thank you Mommy." It always sends a shiver through my body and a tingle through my pussy.

A couple of weeks later I'm walking pass Greg's room, the door is wide open I glance inside. There's a pile of dirty clothes on the floor I hesitate for a second looking around the room, being Monday it's empty as Greg is at work.

I'm tormented, pulled between an insatiable desire for Greg's monster cock and the logic that he's my step son, that I'm happily married to his father and any sort of physical interaction is totally inappropriate.

But can I trust myself to do the right thing if an opportunity presents itself again, I don't know.

As I step inside the room I hear the door close behind me.

"Hello Mommy."

For some reason Greg isn't at work, he's stands at the door naked, his monstrous cock hard and enticing.

"Come her Mommy on your knees."

"Yes Sir."

Actually I don't know why I said 'Sir', it somehow just feels an appropriate response. Also walking over and getting on my knees in front of him feels completely natural, I do it without hesitation or question.

My next action also feels natural, without thinking or being told I take hold of his cock with both my hands as I stretch my mouth wide taking in it's head.

Kneeling before Greg my hands pump his cock as I suck and lick the head, my jaw aching as I force my mouth to stay open, making myself gag as I try to swallow it. Greg's grabs the back of my head, he moves my head forcing his cock deeper down my throat, I cough and gag, saliva pouring from my mouth making my top soaking wet.

Greg comes in my mouth pumping several streams of cum down my throat before pulling his cock out and dribbling cum over my face.

I hadn't noticed earlier but he has his phone in his hand, he has been filming and taking pictures of me.

Also for the first time I notice something else, he is hairless, he has no pubic hair, he is shaved perfectly smoothed.

He moves away lying down on his bed, I remain on my knees watching him, I can feel his cum dribbling down my face and dripping onto my top.

"Come here Mommy, take off your clothes."

Standing up I walk towards him, removing my clothes as I look at his semi hard cock glistening with my saliva and his cum. It twitches as I stand before him naked, hardness slowly returning as his eyes wander over my body.

To be honest I'm getting excited as I think he's going to fuck me, my pussy getting wetter by the second as I stand admiring his growing monster.

He is taking more pictures of me, nude pictures now, is he going to film me as he fucks me.

"You can go Mommy, clean yourself up."

I'm disappointed, I want to feel him inside me, but I do need to clean up, Drew and the girls will be home shortly. I go to my ensuite, stripping off I step into the shower, my fingers playing with my nipples and pussy as I masturbate under the stream of warm water, my eyes close as I imagine that the water running down my face is actually streams of Greg's cum.

Going to my underwear drawer I find it empty, there no bras or panties, all that is in it is a can of shaving cream and a razor. I run my fingers through my bush, I know a lot of women shave now days, it's something I have never worried about doing in the past.

Picking up the can and razor I smile, blushing as I step back into the bathroom to prepare my pussy for Greg.

It's been a month since I stopped wearing underwear, since I first shaved my pussy. Drew asked me why I did it, I just told him I read in a book that it gives you a more intense orgasm. It hasn't made any difference when Drew fucks me though he seems to like eating a bald pussy more.

When I came out of the bathroom after shaving my pussy that first time I found a dress lying on my bed, another message from Greg, since then I only wear dresses around the house.

That first evening sitting at the dinner table in a dress with no underwear felt uncomfortable and I nearly jumped out of my skin when Greg placed his hand on my bare thigh. His hand slide up under my dress, fingers glided over the smooth skin around my pussy, trying to compose myself I took a deep breath clinching my hands into fists as I looked at him, his finger rubbed along my pussy lips as he smiled at me.

That was the beginning of a daily routine, each dinner time his fingers explore my pussy.

After the first shave I didn't shave for a couple of days and I had stubble, that night when I went to bed I found a razor lying on my pillow. Now every day with my morning shower I shave my pussy.

To say I'm getting frustrated is an understatement, no matter how often Drew fucks me or I masturbate I'm not satisfied, I want more I want Greg. It's feels like an eternity since I first held his cock in my hand and mouth, since I first tasted his cum. Each evening at dinner he fingers my pussy, every Tuesday I parade around the house naked for his entertainment, sucking and jerking his cock off as he commands. Whenever he brushes pass me his hands always end up under my dress for a brief moment and even when the family is at home I often find myself on my knees in his bedroom sucking a load of cum from his cock.

But I want more, I want to feel him inside me, I beg him to fuck me, I literally throw myself at him, climbing into his bed late at night naked, rubbing myself against his body, his cock. All he does is laugh at me, telling me I'm a worthless slut, making me masturbate in front of him as he films me before forcing me to take his cock in my mouth.

I lie in bed at times wondering what this hold he has over me is, why when he hasn't even fucked me am I so drawn to him. In a way it would make sense if he had fucked me, if he had given me an earth shattering orgasm like I have never experience before. These rational moments are few and fleeting, replaced by a desire and hope that next time we meet he will fuck me.

I'm his, I'm his submissive bitch, I have just jerked him off in my own bed and I'm now licking and sucking his cum off my sheets. As I do he holds his phone for me to watch a video, a video of me masturbating as I beg for his cock, telling him how magnificent it is, telling him that I am his to use. In reality several months ago I would have been horrified to see anyone act as depravedly as I'm acting in the video, now I don't care as I keep saying I'll do anything in the hope of getting fucked.

I discovered or more correctly confirmed a couple of weeks ago that I'm not the only one fantasying about getting fucked by Greg. I've long suspected that my daughters still discuss his cock but was shocked by what I stumbled upon one night.

It was the early hours of the morning as I crept out of Greg's room, I was heading to the bathroom in the hallway to wash cum off my face and tits when I noticed the girl's bedroom door slightly ajar and a glow coming from inside. At first I'm worried that they were peeping out and saw me stepping out of Greg's room naked, as I approach the door I hear murmuring noises and moans.

Pushing the door slightly wider I looked inside, both girls are lying on Jasmine's bed, mobile phones in front of their faces, the glow from the screen bathing the girls in a soft light. Moans are interspersed by comment about Greg's cock, about how they want to feel it in their pussy's, how they want to taste it but it's not the talk that really shocks me. It's the fact the girls are naked with Brittany's leg lying over Jasmine's leg, a large dildo in each of their hands as they fuck each other with them.

I don't know what to do, I can't burst into their room naked and covered in cum but my daughters fucking each other, I'm shocked.

I didn't do anything then and haven't done anything since, I decided at the time that it would be best to wait and hopefully catch them again in the act.

The girls are only a slight distraction, my growing hunger for Greg's cock is all consuming.
