The next three weeks were a whirlwind of sex.

That night (after my crazy threesome with my Mom and my new older girlfriend), after a good nap to recover, I made it to the newscast half an hour early.

Security wouldn't believe me so I had to text Miranda who came and pulled me inside, her tongue greeting me.

She entwined her fingers with mine and led me into the studio where I was promptly introduced to her ex, Mark.

"Mark, this is my new boyfriend, Curtis," she said, her arm hooked in mine.

Mark looked at me with such disdain I was suddenly rather nervous. Ignoring me completely as a threat he turned to Miranda. "Isn't he a bit young for you?"

"Isn't Brittany a little dumb for you?" she countered, sharply.

"Whatever," he said, walking away.

Her smile was big as she pulled me into her dressing room for a quick blow-job. As soon as the door was closed my fantasy jerk-off woman all these years was on her knees devouring my cock. Once she had swallowed my seed, she stood back up and kissed me sweetly, her tongue darting between my lips, the last remnants of my cum given back to me.

I watched the show live, which was surprisingly boring and frantic, and once done I was face to face with Mark.

"How old are you, kid?" he asked, sizing me up.


"You know she is just using you, right?"

I shrugged. "Well, if that is true there could be worse things to be used for."

He laughed awkwardly before threatening me. "I don't want to see you around here."

Miranda showed up just as Mark poked me in the chest with his finger. Miranda joked, "Mark, you had your chance with me. Leave my boy alone."

He sarcastically agreed, "Boy is the right word."

Miranda shot back. "Be careful about your word choice, tiny. Curtis is a real man and unlike someone I won't mention can get it up more than once. On that note, Curtis let's see how many times you can get it up in one day. So far it is four if I recall."

She grabbed my hand and pulled me along as I blushed like an embarrassed schoolboy. Once in her room she closed the door and tore of my clothes. "Curtis, I am so fucking horny. I want you in me now."

Like a kid in a candy shop I grabbed at everything. I squeezed her ass, I cupped her breasts and I slid a finger inside my dream woman's wet pussy. Each action had her moaning like a porn star and gasping like she was down to her breath.

Once on her couch, I dove between her legs and sampled her heavenly taste. On contact her moans increased and continued as I eagerly lapped her pussy. I don't know if I was that good or she was just that horny, maybe both, but she came hard only a couple of minutes in. As soon as she was done, she straddled my rock hard cock and bounced up and down on it. She easily devoured all eight inches with ease and I just watched, in complete awe, as my most common stroke fantasy, other than my Mother, rode me. She purred, "Do you like this, Curtis?"

"Fuck yes," I moaned.

"I love your quick recovery time, stud," she moaned.

Acting studly, my confidence brimming, I replied, "I can go all night."

She smiled, "Don't make promises you can't keep. I have just hit my sexual prime and I crave cock constantly."

My balls bubbling from the reality that Miranda Collington was my girlfriend and was riding my cock with reckless abandon, I grunted, "I'm not going to last much longer."

I expected her to get off me, but instead bounced faster as she begged, "Fill my cunt with your cum, baby. I want to feel your cum explode inside me. Come baby, come for Miranda."

I needed no further encouragement as I shot my load deep inside her. She didn't miss a beat as she continued riding my cock, milking every last drop of my cum. Finally getting off me, she moved beside me and kissed me passionately. One would think I would be spent after five loads today, two in my Mom and three more in Miranda, but my cock never lowered.

We chatted for a few minutes, where I learned the wedding was actually in Las Vegas and that she wanted me to come for a four-day trip. I couldn't believe my past twenty-four hours. I had fucked my beautiful Mom and I had begun fucking a local celebrity. Life could not get better than this...could it?

One more lengthy fuck and I headed home exhausted with my cock raw. I don't think I even stroked myself six times in one day. I crashed in my bed, still dressed and fell into a deep sleep.


I was awakened the next morning by my mother's lips wrapped around my cock. It is easily the best way in the world to be waked up...a blow-job from your mother. Even though I shot six loads the day before, it didn't take long to get me stirring. Once awake, Mom straddled me and allowed her hot lava to engulf my just wakened cock and said, "I hope Miranda didn't wear you out, I need some quality time with my son."

"She is a minx," I moaned as Mom bounced up and down on my cock, but added, "But I will always have time for you, Mom."

"You say the sweetest things," she purred, squeezing her breasts together and leaning forward. I took her stiff nipple in my mouth and bit gently.

She let out a soft moan and teased, "Don't leave any incriminating evidence."

I bit harder and teased back, "Is my Mommy-slut telling me what to do?"

She moaned, "Yes, I am. Now fuck me, big boy."

Never one to refuse such a request, I began bucking my ass up, my cock pistoning inside her like a well-oiled machine. Her luscious breasts bounced in my face and her moans of pleasure increased proportionately. "Oh god baby, fuck Mommy. Your cock feels so good in Mommy."

Her constant reference to being my Mommy only made it hotter, a constant reminder of the taboo act we both were participating in so eagerly.

"You love my cock don't you, Mommy?" I asked.

"I fucking love it son. I can't get enough of your big stiff cock," she moaned, as I continued to fuck her.

Getting tired from this position, I ordered, "On all fours Mommy. I am going to fuck you like a dog, like you're my pet...my pet Mommy."

"Oh God, Curtis. That is so fucking hot," my sexy Mother replied, obeying my order and getting on all fours.

Getting behind her beautifully tight ass, I put my hands on her hips and allowed my cock to roam and tease, rubbing against her lips, but not in her. Mom who has never been overly patient, demanded, "Shove your cock in me, Curtis, now!"

I spanked her ass gently, before sliding my cock inside the burning warmth of my mother. "Sooooo demanding, Mom."

"Aaaah, fuck, yes," she moaned the instant I filled her. "I can't believe how good you feel in me, son."

"Right back at you, Mom."

My first load of the morning usual came really quickly and this time was no different. Only a few minutes into my hardcore fucking of my Mom, I felt my balls boiling and I warned, "I'm going to come soon, Mom."

In lightning speed, my Mom turned around and devoured my cock with her perfect cocksucking lips. She furiously bobbed back and forth like the eager slut she was and I rewarded her with a very full load of my cum. Swallowing every drop, she continued bobbing up and down on my cock until I asked her to stop, the sensation now making me have to pee.

When I returned from the washroom, my sexy Mother was lying in my bed waiting for me. She said, strangely like a rather insecure teenager, "Don't you forget about your Mother's needs now that you will be spending so much time with your boyhood fantasy girl."

I corrected her. "Oh Mom, you were my first and still are my most constant boyhood fantasy girl."

She slapped me playfully. "I bet you say that to all the older women you fuck."

I leaned and kissed her tenderly, with the passion of a man in love, gentle, intimate and yet still with the lust that accompanied my feelings for her. Breaking the kiss, I said, "Mom, I love you."

"I love you too, son," she answered.

I stood up, suddenly hungry for breakfast, and said, "Did you know the wedding is in Vegas?"

"I do now," she quipped.

"I'm not even old enough to get into the bars and casinos," I pointed out.

My Mother, always the witty one, quipped back, "But you will be old enough to get into Miranda."

"Touché," I replied, still bathing in my good fortune.

Mom got up, and said, "Go shower, I will make my big boy some breakfast."

"You really are the best mother in the world," I complimented.

Walking to me and firmly grabbing my semi-erect cock, "And don't you forget it." She gave one last tug and disappeared.


I put on hold my attempt to find out more about Ellie's past relationship with my mother, as I focused on Miranda and the upcoming wedding, which had become a full-time job. Miranda paraded me around at work, flaunting me in front of her ex every chance she got and played with my trombone over and over again.

A few days later, I had just finished fucking Miranda in her dressing room, which had become a daily routine, when she said, "I am going to buy our airline tickets tomorrow. You are still good with coming?"

I replied with sexual innuendo, "I love coming with you."

"Oh you dirty boy," she teased.

Throwing an idea out there, I asked, "What do you think of having Mom and Ellie join us?"

She asked, pouting like a school girl, "What, I am not enough for you?"

"On the contrary, Mom clearly misses being with Ellie and needs to be pushed past the point of no return and well...what happens in Vegas...."

Her devious smile crossing her radiant just-fucked face, she asked, "You want to play lesbian matchmaker with your married Mom?"

"Well, that is an interesting way to put it," I reflected with a grin.

"You know that Ellie used to Domme your Mom right?"

"Mom hasn't said much more than that if she ever gave into Ellie again it would be impossible to ever break free again."

"Tell you what, I love the idea. But how are we going to get Ellie to go along?"

"I already thought of that. You invite her as your 'plus one' and she will be pleasantly surprised when Mom and I are on the plane."

"Hmmm and I assume you have a plan while we are up in the air?" she guessed, her hand slowly stroking my already growing cock.

"In my head I have a million different variants," I admitted.

"Do you want to fuck Ellie?" Miranda asked.

"Well..." I began, knowing answering such a question was dangerous.

"It's ok, baby," Miranda said, "I would love to see you fuck her. I would also love to play with her as well."

"It will be a pleasant surprise for Mom," I said, as I tapped my cock on Miranda's sweet lips.

"I will make arrangements tomorrow," she promised before taking my cock back in her mouth.


The next day and few days since I had last fucked my mother, she came up to me in the kitchen as I was getting ready to go meet up with Miranda. Her hand went onto my cock while Dad was in the other room watching the news, and she pouted, "Have you forgot about Mommy?"

My stiff cock gave its own answer as I moaned softly, "God no, Mom. I am always ready to assist you in any way possible."

She unzipped my pants and fished out my cock. She stroked it quickly. "Fuck, I want your cock in me." Surprising me, she lifted up her sundress, bent over the counter and whispered, "Fuck me, Curtis."

"But Dad is in the next room," I protested.

"Do as your mother asks," she ordered.

Mom had blown me in the bathroom quickly while Dad was downstairs, she had rubbed my cock with her foot during supper a couple of times as well, but we had never fucked while Dad was home.

"You sure?" I asked, still unsure, even as her tight ass bent over had me raring to go.

"Yes, fuck Mommy, Curtis, now!" she begged, with a whisper.

Obeying my Mother like a good son should always do, I went behind her and easily penetrated her already very wet pussy.

I did slow strokes, still pretty scared of getting caught by Dad fucking Mom. Mom's moans were quiet and controlled, unlike when we were alone and she was an animated slut.

I continued to fuck my mother for three minutes or so when the phone rang. My Dad never answered the phone and it was in the kitchen anyway.

Mom cursed under her breath, "For fuck sakes," and went to the phone reluctantly allowing me to slip out of her. Answering the phone, she rolled her eyes. "Hi Mom."

Knowing that this would be a long conversation, I put my cock back in my pants, and winked at Mom, whose red cheeks would have been excellent CSI evidence of our crime. She said, "Mom, give me a second. Curtis is just leaving."

Mom put the phone down and came over to me. She whispered in my ear, her hand firmly on my still stiff cock, "Don't forgot about Mommy while you are out gallivanting with Miranda."

"Of course, not Mom. You will always be my first choice."

She kissed me on the lips, shoving her tongue in my mouth, before saying, "And don't you ever forget it."

I quipped, "How could I Mom, you are my MILF slut."

She smiled and mocked authority, "Don't you use such language with me, unless you are in me. Fuck, I wish your Dad was gone. I guess I will have to fuck him tonight."

"Oh, the sacrifices," I mocked.

"Don't get me started," she sighed, before asking, "Have you fucked Miranda in the ass yet?"

"No," I admitted, even though the thought had crossed my mind when she was bent over and I was fucking her in her favorite position, the submissive doggy style.

"Have you fucked anybody in the ass, son?" she asked, rubbing my cock firmly in my jeans.

"Noooooooo," I moaned.

"Well, tomorrow your Dad is heading out of town and I am going to be your first. Is that understood?"

"Yes, Mom," I agreed, very enthusiastically.

"Good, so tomorrow you are mine, all day, understood?" she asked with one final squeeze.

"Yes, Mommy," I replied.

I watched her saunter, purposely using her sexy wiggle. She went to the phone and began talking to her Mother, seconds after promising her son her ass. My life was fucking amazing.


I headed out and to see Miranda again.

When I arrived at the studio Mark confronted me in the parking lot. He had clearly been waiting for me. "I thought I warned you to stay away from Miranda."

I replied, "Are you not getting married to someone else? I think such a commitment prevents you from any such authority."

"Don't get smart with me," Mark threatened.

"Or what?" I asked.

"Don't mess with me."

I walked past him and countered, smugly. "I am not here to mess with you. I am here to mess with Miranda, over and over again."

"You fucking punk," he began, as I walked into the studio.

Confused at the guy's threats, I shrugged them off and went to shoot my usual pre-load show in Miranda's perfect cocksucking lips. As soon as I entered her room, she smiled and pulled me in for a passionate kiss.

I eventually told her about my encounter and Miranda cursed, "Fuck. He just won't grow up. Fucking men they don't know what they got till they lose it."

I asked, although I was scared of the answer, "You don't want to get back with him do you?"

"I'd rather remain celibate and you know how much I love sex," she replied, before her anger shifted into mischief. "Oh, but two can play at that game."

"What do you have in mind?" I asked curious.

"You will see. But I will have to wait to swallow your cum until right before show time."

I shrugged, "Whatever suits your fancy."

We talked about the Vegas trio for a while and Ellie was in and she planned to talk to my Mom tomorrow. Miranda smiled, "Your devious plan to get your Mom to be a dyke to a Mistress while you watch is almost all in place."

"Don't forget, the plan also includes fucking Ellie too," I added.

"Don't you be getting me jealous. I already have to share you with your Mom," Miranda teased, falling to her knees.

She took my cock in her mouth and after a couple of deep bobs asked, "Was your car recently parked in your Mom's garage?"

I laughed at the horrendous visual. "Yes, we fucked for a few minutes in the kitchen while Dad was in the living room. But the phone rang."

"Oh you poor boy. You didn't get to come in your Mom," she mocked, before asking, "Will I do?"

I grabbed her head and lead her mouth back to my raging hard-on. "Yes, baby, you will more than do."

Ten minutes later, which is as long as I usually lasted in the sauna of lust that was Miranda's mouth I began shooting my cum in her mouth.

Unlike her usual swallow every drop routine, she moved back and caught my cum like a basket. Once done, she stood up and left the room.

Curious as hell, I pulled my pants up and followed my devious girlfriend, who went directly to Mark, seated at the anchor's table and leaned forward her mouth open, apparently showing her mouthful of my cum to her ex.

He went red as Miranda clearly swallowed it all. I was just in earshot enough for her to say, "Remember when that was your pre-show routine?"

"What the fuck, Miranda?" Mark questioned.

Miranda, now mad, threatened, "Leave my boyfriend alone."

"Boy is right," he quipped back confidently.

Miranda laughed, a laugh dripping with scorn, "Don't you dare judge, Mr.-Can't-get-it up-for-round-two-without-a-nap."

Others in the room couldn't help but let out a quiet laugh as Miranda turned and walked away, leaving a red faced Mark utterly speechless, probably for the first time in his egotistical life.

Miranda walked right to me and shoved her tongue down my throat for all to see. I could taste myself on her tongue, but was thrilled to finally have the public affection she had not given me until this second.

Mark glared at me and I smugly winked back at him.

Miranda and I fucked after the show for a lengthy hot marathon session where I deposited two more loads in her, one in her pussy and another in her mouth.

As I was getting ready to head home for the night, I mentioned, "I am going to stay and hang out with Mom tomorrow, sexy."

"You are, are you? You are such a mother-fucker," she teased.

I retorted, "Jealous?"

She shrugged, "Maybe." As she kissed me goodbye she threw me for a loop as she finished with, "Of course, the question is, am I jealous of your Mom for getting to fuck you or jealous of you for getting to fuck your Mom?"


The next day, Dad left for an overnight meeting somewhere and I replaced him in my Mother's bed. I had just deposited a load in my Mom's cunt to start the morning when she informed me, "Hey baby, I am coming to Vegas with you."

Acting surprised, I said, "Really? How did that transpire?"

"Didn't Miranda tell you?"

"No, but we don't do a lot of talking when we are together," I joked.

"You are such a male slut," Mom joked.

I corrected, "When a girl fucks more than one guy she is a slut. When a man is scoring with two women he is a stud. Unfair I know, but those are the rules of society. I don't make them, I just follow them."

Slapping me playfully, she questioned, "Are you calling me a slut?"

As my finger traced her firm breasts, I answered, "You are my slut, Mom."

"Well then," she began straddling my still semi-erect cock, "if I am going to be labelled a slut, I better make it worthwhile."
