Josh came home from his orientation trip and was somewhat surprised to find his dad just sitting on the couch. Last time he came home from being gone, his dad was naked on the table waiting to be bred. Josh dropped his stuff and went over to give his dad a big kiss on the lips. Based on Eric's reaction, he knew something was wrong.
"Dad, what's going on? Is the baby okay?"
"There's no easy way to tell you this Josh, so I just have to get it all out. I... I... cheated on your while you were gone," Eric said, immediately breaking into tears.
"What do you mean? How? With who?"
"Well you know how horny I had been lately. And I was so agitated I had to mention it to Dr. Tyler. Next thing I knew he was fucking me on the exam table"
"Wait... Dr. Tyler? I mean I knew he was gay but didn't expect a doctor to have sex with his patients, at least outside of porn."
"And I had sex with him a second time too... "
Eric laid out the full story of getting the dildo caught in his ass, Dr. Tyler coming over to remove it and him expressing his "appreciation."
"If you hate me... I understand. I love you and I shouldn't have hurt you like that."
Josh's face was like unreadable as he sat quietly next to Eric.
"Dad, I won't pretend I like the idea that you were with someone else. But I'm relieved it was just... sex... and not some sort of emotional thing. That would be a lot harder. Besides, I also have something to confess," Josh inhaled deeply before continuing. "Liam was on the trip with me and I hadn't seen him in over two months since he moved away. We caught up and got drunk and well... we ended up sucking each other off."
This was quite a shock to Eric. Liam and Josh had been best friends since they were 8 and while they had a close bond, Eric had never even seen hints of anything romantic or sexual between the two.
"Dad are you upset?"
"I'm more, well, surprised. I mean I knew you guys were close but this is another level."
"Honestly, it wasn't the same as when I'm with you. It was more like... we hadn't seen each other in so long and we just got overwhelmed by being together again?"
"And drunk."
"And drunk. So you don't hate me?"
"After what I did the past week, I have no grounds to hate you. Do you hate me?" Eric replied sadly.
"No... but," a wicked smile lit up Josh's face, "I might be upset if you don't tell me more details about how and where Dr. Tyler fucked you."
Eric felt himself get aroused as his son's hands worked their way up his legs.
"We were in the kitchen."
"Well, then let's go," Josh said, picking up his pregnant father and carrying him in his strong arms to the kitchen.
"And I got down on my knees and started sucking him."
Josh unzipped, setting his semi-erect cock free and gently nudging his dad to the floor.
As Eric began swallowing the now-familiar cock, fondling the firm balls, and looking up into his son's beautiful face, Josh let out a powerful moan. Eric licked his son's shaft from tip to balls, spending extra time swirling circles around the cockhead with his tongue, as he learned his son liked it.
Josh pulled Eric off his dick before he blew his load: "then what happened?"
"Well he turned me on my back and leaned me over the counter and... "
At that, Josh spun his father's delicate frame and lined his cock up at his dad's hole. Eric felt his son's hot breath on his neck as Josh pushed slowly into him.
Josh increased his speed, the tender sex turning into rough fucking.
"Did you like it when Dr. Tyler fucked you Dad?" Josh panted.
"Yes. I. Did." Eric answered honestly.
"That hole just really craves being filled with cock, doesn't it?"
Eric found this more aggressive side of his son surprising, but also arousing.
"Yes, but especially your cock Josh!"
"Get ready because this cock is about to seed you again!"
"Give it to me Josh. I need your cum inside me!" Eric practically begged.
With that, Eric felt Josh's load filling him up. With two quick strokes of his own cock, Eric shot a load all over the kitchen floor.
Josh slid his cock out of his dad and turned Eric to face him. "I missed you so much. And I love you so much Dad."
Eric rested his head on his son's broad shoulders, and Josh picked him up and carried him to shower off together.
**************************************
The semester started and Josh got into his routine of classes, swim practice/meets, and socializing (at Eric's insistence). For Eric, it was similar to when Josh was in high school and busy most of the time, except now Josh shared his bed and fucked him in the morning before he left for school, at night before bed, and when he had a long break between classes and a load to be worked out. Josh occasionally had friends over, and they would hang out in the downstairs unit that was - in name, anyways - "Josh's place".
The other difference for Eric was that he was starting to get, well, bigger. By October, Eric was in his fifth month of pregnancy and while it wasn't obvious he was having a baby since the weight wasn't pushed all the way forward, he was definitely nowhere near fitting into the clothes he used to wear. Dr. Tyler kept a close watch on the baby and each week reported good news of normal development. With Josh back, Eric's sexual needs were being met and the relationship returned to being a more normal doctor/patient dynamic.
If Eric was self-conscious of the way his body was changing, Josh had the opposite reaction. Knowing he had knocked up his dad, and could see the results, turned on Josh like never before. Josh would kiss all over his dad's belly on his way down to Eric's cock, and gently rub it with Eric's cock in his mouth. When they fucked, Josh adapted to more comfortable positions for his dad, but his 8" cock never seemed to go down.
**************************************
Liam had been over a few times to hang out with Josh. Despite the orientation trip encounter, Eric felt no jealousy or suspicion. Eric mostly focused on trying to keep his lower half obscured by standing behind the kitchen counter or sitting on the couch under a blanket. Avoiding questions/inquisitive glances seemed the best course of action.
Liam was still the good kid he always was, sweet and very handsome. At 18, Liam was 6'2", 180lbs of pure muscle, and had the stunning combination of blue eyes from his Scandinavian dad and dark skin from his South African mom. Eric could only imagine the visual treat of watching Liam and Josh suck each other off.
Eric got a text on a Friday night Liam was over that Josh was staying downstairs because they had drunk too much and Liam was staying over.
"Don't worry, nothing happening ;)" Josh added to his text.
"Shame, I was hoping to watch :-*" Eric wrote back.
Sometime during the middle of the night, Eric felt Josh climbing into bed with him.
"Honey... aren't you supposed to be downstairs with Liam?" Eric asked groggily.
"Yes, but something came up."
Eric woke up more, "what?"
"This," Josh said, guiding his dad's hand to his rock hard cock.
