If you have been following my stories you know that I am a young, female medical assistant and I work for a urology group. When I first started it was just one urologist but now it’s a group of three. It’s somewhat rare for a woman to work in the urology field. I must admit that I chose the field because I am somewhat obsessed with penises. I have become quite adept in my profession and my expertise in certain procedures has led my doctors to have me provide most of the prostate exams. Many male patients are quite reticent to have a male doctor insert his finger in their anus to check his prostate but are much more open to having a woman do it. Especially a young, very attractive female such as myself. I am also entrusted to extract semen samples when required and I am not hesitant to lend a helping hand if needed.

Robert, one of my male patients, who I cured of erectile dysfunction, had approached me about providing some private tutoring to his 16-year old son. The son was painfully shy and also very ashamed of his quite large penis. The son was convinced he was some kind of freak with a nearly nine-inch long and very thick penis plus a really oversized head on his cock.

My full name is Kelly Wainwright but everybody calls me Miss Kelly. I am currently single and am not seeing anybody regularly but am getting my sexual needs well taken care of by various men.

Robert, who is quite wealthy, paid me an obscene amount of money for twice weekly two-hour sessions with Jack, his son. It took me no time at all to convince Jack that rather than be ashamed of his penis, he should take great pride in it. In addition to a number of one-on-one sessions where I gave Jack’s penis a serious workout, I convinced both father and son that one way to relieve Jack’s fears about his penis being a turn-off to women, would be to spend a couple of weeks going about their normal daily business around the house with their pants unzipped and their cock and balls exposed. I felt that Robert needed to join in because Jack was too shy to be the only male in the household exposing his genitals. Robert employed an all-female staff of five women and prior to the introduction of this experiment he explained to the staff what they would be doing and received everyone’s approval of the plan. This turned out to be an overwhelming successful effort and as a result at one time or another all five of the women had sexual contact of some type with both Jack and Robert. Although the two-week trial was technically over, Jack continued to expose himself to the staff from time to time which usually led to some type of sexual contact between Jack and one or more of the women.

One other treatment that Miss Kelly devised was semi-regular cock-to-cock jack-off sessions with both Robert and Jack. This turned out be a terrific bonding experience between father and son. Robert had an equally large penis to his son’s so C2C sessions were quite successful. This originally was intended to be a one-off experience but both Jack and Robert enjoyed it so much that Miss Kelly tried to fit in a C2C session at least once every couple of weeks. In truth, Miss Kelly’s services were no longer really required, but everybody was having so much fun that Robert continued to pay her.

But now Miss Kelly had decided to take the bonding experience between father and son one step further. All three were in the special “treatment room” that Robert had put together for Miss Kelly to perform her sessions with Jack. They were scheduled for another C2C session and both men were naked with erect cocks bouncing against their bellies.

“I want to try something different this time,” Miss Kelly explained. “It’s intended to take the bonding experience to a higher level. This time we are going to have you two perform fellatio on each other’s penises. A true father-son suck-off.”

“But isn’t that too gay?” blurted Jack. Robert gave her a doubtful look.

“No, it’s not gay at all. It’s just an expansion of your sexual experiences. Just because it’s a man lips wrapped around your penis instead of a woman’s does not make it gay. Plus having it occur between a father and son is a very loving bonding experience. What I want you to do is to start off with solo sucking. By that I mean Jack will suck his dad’s penis and then Robert will suck his son’s. Then you can try the 69 position where you both suck each other’s cocks at the same time.”

“But what about you, Miss Kelly?” queried Jack. “What will you be doing?”

“Don’t worry about me,” Miss Kelly replied, “I will be helping out as things progress.”

Most of Miss Kelly’s and Jack’s sexual adventures had taken place on an oversized examination table in the special room set aside in Robert’s mansion for Jack’s training sessions. Robert had originally attempted to somewhat duplicate the examination room at the doctor’s office where Miss Kelly worked. But at some point Robert had a king sized bed moved into the oversized room and that’s where the three of them were currently situated. Miss Kelly had disrobed and now all three were naked and the men’s two cocks were harder than ever.

“Robert, you lay back,” Miss Kelly instructed, “and Jack, get between your dad’s legs and start licking and sucking his penis.”

“Are you sure this is okay, Miss Kelly? I feel really weird putting my dad’s cock in my mouth.”

“Go ahead, Jack,” she replied, “once you start sucking his prick it will feel extremely natural and I guarantee you will enjoy it.”

As Jack leaned over and tentatively started licking his dad’s rock hard cock, he felt a wet tongue enter his anus. Omigod, he thought, that feels amazing. Feeling Miss Kelly’s tongue exploring his asshole spurred him on to lick and then suck his dad’s raging hard cock. As the head of Robert’s prick disappeared into Jack’s mouth, the son also started jacking the shaft of his dad’s big cock. His head bobbed up and down on Robert’s prick and the more he sucked the more he got into it. Then he felt Miss Kelly’s hand reach between his legs and grasp his distended prick and start stroking it. He went into sensory overload with Miss Kelly’s tongue and hand working him over plus the feeling of his dad’s pulsating prick forcing its way down his throat. Robert put his hand behind his son’s head forcing him to take his cock even deeper. Somehow Miss Kelly had managed to get her other hand up between Robert’s legs and he soon felt her lubricated finger slide right into his ass. As his cock pumped in and out of his son’s mouth, Miss Kelly’s finger pumped in and out of his asshole.

Jack had never experienced anything quite as arousing as what they were doing and as a result, he couldn’t hold off cumming as long as he would have liked. Miss Kelly could tell Jack was about to cum so she tightened her grip on his penis and increased the speed that her hand flew up and down his 9-inches of rock hard meat. She felt his body stiffen as several blasts of semen shot out of his cock splattering all over his dad’s balls and Miss Kelly’s wrist. When Robert felt his son’s cum coating his nutsack he couldn’t hold off and filled his son’s mouth and throat with a cumload of his own. Jack, of course, had never experienced somebody ejaculating down his throat. He had unloaded plenty of cumshots down many willing female throats and always wondered why so many women seemed to enjoy taking a cumload. Now he was getting a first-hand experience of a big cock spurting stream after stream down his throat and he loved it. The feeling of accomplishment in sucking his dad’s cock to a cum explosion was overwhelming. It just made him increase the suction on his dad’s big penis so that he could suck out every last drop of semen.

Finally, when there was no more semen to be had, and his dad had to ask him to stop sucking because his cock was way too sensitive, Jack rolled off onto his back. His huge prick was still dripping semen as Miss Kelly slid forward and started licking Jack’s cum off of his dad’s balls. She sucked one of his nuts into her mouth as she cleaned every drop of semen off of him.

“Okay, boys,” Miss Kelly said. “That was a great start. Let’s take a few minutes and then Robert, it will be your turn to suck off Jack.”

“Oh, Miss Kelly,” exclaimed Jack, “you were right about it being a fun experience to suck my dad’s cock. And it didn’t feel gay at all. Just a fun thing to do. His dick was really big when it was jamming its way down my throat. Now I know what it feels like to you when you suck my cock. And when the cum started spurting I thought I was going to choke but I really loved it. And it was pretty neat that as soon as I started shooting semen all over dad’s balls, he started cumming in my mouth.”

“I’m glad you enjoyed it. I thought you would,” Miss Kelly replied.

“I’ll be honest with you,” stated Robert, “when you first suggested that we suck each other off, I really didn’t think it was a good idea. But you’ve always been right in the past and this was no exception. Having my own son suck my cock and receive a load of my semen down his throat was the ultimate father/son bonding experience. I recommend it highly to all fathers and sons. And knowing it was my own son’s semen spurting all over my balls was just icing on the cake. Now I am really looking forward to sucking him off and swallowing his cum in return.”

Being a horny teen, Jack’s cock was still mostly erect. He was eagerly ready to go again. He was looking forward to his dad’s lips sliding over his cock. He lay back and spread his legs. His cock proudly stood straight up. “Dad,” he said. “My prick is ready for you.” Robert positioned himself between Jack’s legs. He was on his knees and bent over and started licking the huge head on Jack’s cock. He felt Miss Kelly slide under him on her back. His flaccid cock hung down and she positioned herself so her mouth was directly below his cock. She raised up and took the head of his cock in her mouth and started licking and sucking it. It immediately began to get hard. Within a minute or so it was fully erect and throbbing in Miss Kelly’s mouth.

Robert held his son’s massive cock in one hand and planted a wet kiss on the tip. He held the kiss against Jack’s cock head and then slowly let his lips slide down over the smooth distended skin of his son’s glans. Once he had the entire head of Jack’s prick in his mouth, he started sucking it. As his head bobbed up and down, he could feel his lips slide over the coronal ridge and he knew that the sensation for Jack must be driving him wild. He wanted to focus 100% of his attention on giving Jack a world class blowjob but he was somewhat distracted as Miss Kelly worked her magic on his own prick.

When they started this second round, he assumed it would take him forever to cum again. But experiencing Miss Kelly’s world class ministrations on his now fully engorged prick, he knew it would be just a matter of minutes before he unloaded his balls deep down Miss Kelly’s greedy throat. She was somehow raising up on each stroke and taking his entire 8-1/2-inches of rock-hard meat down her throat. She also had clutched his nuts in one hand and was gently massaging them. Her other hand had found its way to the crack of his ass and he felt her finger penetrate him. She thrust her oiled-up finger in and out of his rectum. It felt so damn good he knew he was about to ejaculate again. The sensations that Miss Kelly was providing him spurred him to even greater activity on his son’s cock. He let the boy’s cock slip out of his mouth. He stuck his index finger in his mouth and liberally coated it with saliva. At the same time that he took Jack’s cock back in his mouth he shoved his wet finger up his boy’s asshole. He felt Jack’s body stiffen and his prick seemed to swell to extra hardness. Robert went wild in a frenzy of cock-sucking. He had never sucked a cock before, and he was surprised at how easily he got into it. Miss Kelly was right again. Sucking a cock was a huge turn-on and he knew this would become a regular ritual between he and Jack. He had never felt closer to his boy than he did with Jack’s giant member ramming its way down his throat.

“Omigod,” Jack screamed. “I’m cumming, I’m cumming!” When Robert heard that he tried to increase the suction on Jack’s cock with his lips sliding up and down the length of Jack’s huge member. His activities were rewarded as a huge gush of semen started shooting out of Jack’s cock and coated Robert’s tonsils. Jack grabbed his dad’s head with both hands as his spasming body jerked and twitched with ecstasy. He was in such orgasmic bliss that he couldn’t control himself. Unknown to Jack, at the same time Jack was cumming, Robert was shooting stream after stream of jism down Miss Kelly’s throat. She greedily swallowed every drop just as fast as Robert could deliver a new stream of semen.

Robert raised his head and let Jack’s cock slip out of his mouth. Robert looked down at Jack’s massive still hard cock. The skin on the head was stretched tight and had a shiny sheen to it. He loved his boy and loved his cock. He leaned down and kissed the head of Jack’s penis. He could feel Miss Kelly’s fingers rolling his foreskin back and forth. She was obviously attempting to milk out every last drop of cum from his cock. He couldn’t see her, but he could visualize her open mouth under the tip of his penis as her expert fingers milked the last vestiges of his ejaculate into her waiting mouth.

After the three of them lay together for a few minutes Miss Kelly wanted to know how soon they would be ready to go on a 69-style mutual suck-off.

Both father and son begged off. They needed some time to savor the experiences they had already had. Time was running short on the session anyway. Miss Kelly was very firm on maintaining the scheduled time for the appointments, so it was agreed by everyone to put off any more cock-sucking until a later session.
