"Have you sucked your Mom's new cock yet?"

"Eww, Dad, that just seems a mouthful too far."

"Then you don't know what you're missing. It's a wonderful experience. Totally makes the sex change operation worth it. I'm glad that we spent the extra money to make it fully operational."

"But how does she come in your mouth?"

"It's amazing what surgery can do these days. She just has to refill the implanted balls. Which she does all the time, so that she's ready to go whenever I am."

Dad reached over and stroked Scott's growing cock while Scott returned the favour to his father.

"I never expected that Mom's reaction to finding out that we like gay sex would be to ask for a sex change."

"Why not, just because she loved sucking cock doesn't mean she wouldn't want to be a he. This way she gets to suck cock while playing with her own shaft."

"I'm glad that she kept her tits. I love to play with those."

"So does she. It makes her cock extra stiff."

"Have you..."

"Let her fuck my ass? Of course. You know how I love a fat throbbing fuck stick up my poop chute."

"Does she do a good reach around?"

"Almost as good as you do. Plus, she loves getting a reach around. She'll let you assfuck her if you stroke her at the same time."

The conversation came to a close as Scott bent forward and swallowed his father's fat cock. It had taken Scott a lot of practice to get used to Dad's girth but now he loved it. Dad's cock was fatter than any of the other cocks that Scott had sucked before his Dad had discovered that Scott had apparently inherited Dad's bisexual proclivities.

Like Dad, Scott was more gay than heteroflexible, but they both still fucked women and loved to eat pussy. Because of that, Scott had been shocked that Mom had decided upon a sex change, and that Dad had gone along.

Still, Scott figured, the family that sucks together fucks together.

As if to prove the point, Dad rolled over and took Scott's cock into the warmth of the parental mouth. Scott loved blowjobs from his mother, but Dad's oral skills were second to none. Scott had been sucked by a lot of people of both genders, beginning at his eighteenth birthday party, but he knew that he would always love Dad's talents the most.

The feeling of Dad's tongue rolling around the rim where helmet met shaft never failed to give Scott shivers. Even better, Dad had the cock of Scott's dreams. He was so glad that Dad had walked in on him giving head to a school chum in Scott's bedroom at the birthday party. At first, Scott was caught aback, panicked by how Dad might react, but all that Dad had done was ask "Mind if I get a turn?"

It had turned into quite a party.

Scott wasn't sure which had surprised him the most- his Dad asking for a blow job, or his mother offering him one, as long as she got to watch Scott swallow Dad's load.

Fortunately for Scott, he seemed to have inherited a natural cocksucking gene and loved the taste of semen. He also seemed to have been born without a gag reflex.

The highlight of that party for Scott had been swapping his Dad's seed into his mother's mouth, receiving his own spunk back. The three of them had then shared a tongue twisting kiss.

The birthday party had just been the beginning of the family fun, though Scott continued to explore with others as well. One thing that he noted was that although his Mom loved to give oral sex, she did not let Scott fuck her. Not that Scott particularly minded. He had met lots of women that loved his cock.

Mom had continued to be fucked by Dad, sometimes while one of them was sucking Scott. Because of this, it was a shock to Scott when Mom announced her desire to have a sex change. Dad had fully supported the move.

After Mom healed from the operation Dad eagerly sucked her cock. Scott enjoyed watching, and before long, they progressed to Mom sucking Scott while Dad sucked her or fucked her ass. Scott had even enjoyed stroking her cock but had not been inclined to suck it. This lack of enthusiasm confused him as well as Dad, though this was the first time that they had openly discussed it.

At the moment, Scott's thoughts about sucking his Mom's new cock were pushed aside by the familiar but still wonderful sensation of gushing great gobs of goo down his father's gullet while Dad simultaneously treated Scott to a blast of baby batter. As always, Scott loved the creamy filling and revelled in the exquisite emptiness of his own balls.

As Scott lay there enjoying the warmth, he considered his father's advice. He could not think of any good reason not to try sucking his mother's new cock. If it turned out to feel too artificial, he would know and not have to repeat the experience. And maybe she would let him fuck her ass.

Scott relaxed until Mom got home, thinking about how he would go about offering to suck her cock. Would Dad initiate some playful sex as soon as Mom arrived, creating an opening for Scott? Would Mom just strip down as soon as she entered, as she sometimes did now that nudity was casual between the three of them? Or would Scott have to seduce her?

"Can you suck Mom's cock when she gets home? That always makes me hard, and should inspire me to join in, or maybe suck her entirely on my own."

"Two tongues can be more fun than one, but for your first time sucking Mom, I suggest that you do it on your own. Not only will you be focused on her, but I think she'll like being on-on-one with you, at least the first time."

Scott remained nude while waiting for his mother to come home. He edged his cock to the point of precum but held off from climaxing. It seemed like hours until Mom arrived. His anticipation could not be greater.

Scott's naked hard cock was the first thing that Mom noticed when she got home. She was horny most of the time, and on the way home, had pictured sex with her husband. But Scott would do just fine.

Mom walked across to Scott, scattering her clothes as she neared. She knelt down and brushed Scott's hand aside, lowering her mouth to her son's thick spongy cockhead. Without even licking him, Scott shot a burst of seed up that splattered on her chin. Mom paused to scoop it with a finger and lick it clean. Then she went down on Scott, fondling her magnificent tight tits at the same time. Scott could not resist the urge to reach out and twist her nipples.

As much as Scott loved the attention, he had something else in mind.

"Mom, I've been obsessing about your cock all day. It is so beautiful. I want to suck it."

Without waiting for a response from Mom, Scott pushed her foreskin back, revealing the glory that was her cock head. The purple monster pulsed in front of Scott's face as he bent forward, falling to his knees.

Scott licked his Mom's shaft, taking his time, wrapping his tongue around the girth and working slowly to the root. His fingers toyed with her artificial balls. He was surprised how real they felt- much like Dad's. Without a pause, Scott's tongue licked Mom's scrotum. He could feel her quiver. Scott slid his lips up to her tip and pumped her shaft with his hand. Mom was so turned on that she did not need any more stimulation. She spurted the thick creamy white liquid up out of her balls. It splattered down Scott's throat. He pulled back and the surge coated his face from his forehead to his chin. Scott used his fingers to scoop the offering into his mouth. It tasted almost like real semen. Since not all semen tasted the same- as Scott knew from experience- the gush from his Mom's new cock was just right.

They lay together on the floor until they caught their breath.

"I want to fuck you," Mom whispered into Scott's ear. Her cock was still stiff.

She reached into a side table and pulled out a tube of lube.

"May I?"

Without waiting for Scott's reply, Mom squeezed a dollop of lubricant onto Scott's anus. She pulled his cheeks apart and thumbed his rosebud. His asshole gaped open eagerly.

Mom entered his colon.

"You ass is just like a nice tight pussy, only your muscles are milking me better."

Scott just moaned in response. Looking up, he saw that Dad was lingering in the entrance to the kitchen, watching, cock in hand.

Mom reached around and found Scott's cock. Mother and son came at the same time, squirting their loads, collapsing on the floor. Mom's wilting weapon was still trapped in her son's anus.

"Look, I think your Dad needs his cock sucked, or maybe a good fuck. Which of us should do it?"

"How about both of us? I love watching you suck him, and I've never fucked his ass yet. That would be a special treat."

Scott's cock was iron hard. So was his mother's.

Mom crawled forward on her knees and gave her husband's hardon a quick lick. Then she pulled him to the floor on hands and knees. Without missing a beat, she rolled under his belly and took his cock into her hungry mouth.

That left Scott to step up behind his father. On the way, he grabbed the tube of lube that Mom had used on him. Scott used a fingertip to paint his father's anal cleavage and then pierced past his sphincter. Dad whimpered gently. This did not discourage Scott, who knew how much his Dad liked to be fucked. Slowly, Scott moved back and forth, drilling deeper with each stroke.

"Your cock is a perfect fit, son," Dad moaned.

That was all it took to make Scott explode, painting his father's bowel with semen. Scott leaned sideways, still trapped inside his father, and watched his mother's cheeks swelling and contracting as she swallowed Dad's load. This continued for about a minute, after which all three collapsed in a pile on the floor. For now, they were done, but Mom's new cock guaranteed that there would be lots of fun in the future.
