Josh woke up as the sun came in through the open blinds. Every part of him seemed to be in pain: his head throbbed, his neck was hot to the touch where he had forgotten sunscreen, and his body ached from the hangover. That last drink was a mistake.
As he slowly came to, he realized his cock was also throbbing, though in a much different way. It was pressed up against the smooth, naked backside of his dad next to him in bed. Wait... his eyes popped open in a double take. Yep, there was his dad asleep next to him. Naked. And Eric's backside was covered in... oh god. Yep, that was his cum.
If Josh had not been hungover, he would have jumped out of bed in horror and smacked himself to make sure this was really happening. But, in his current state, all he could do was roll onto his back as he breathed hard and his mind raced.
This wasn't a crisis of sexuality per se. Josh had on-and-off girlfriends in the past, but would not say he was exclusively heterosexual. More than once he and his friend John had drunkenly made out and/or cuddled. But this wasn't John naked and next to him. This was his dad. This was not normal.
Josh knew he and his dad were really close. They had a relationship that was much closer than any of his friends had with their dads... though their dads were also not single guys with generous alimony and child support.
As Josh looked again under the thin white sheet draping the lower half of Eric, he could not help but admit his dad's body was oddly appealing. Josh was 4" taller than his dad and, whereas Josh was toned and muscled from all his time swimming, Eric was simply skinny and petite. Was it Josh's imagination or did his dad who rarely worked out seem to have somewhat feminine curves with oddly wide hips? I mean his dad always seemed a few levels of testosterone short, but that was what the new treatment thing he was doing was for right?
As Josh thought more, he realized his dad's behavior was quite different ever since he received the stem cell injection or whatever it was. He expected his dad to get a deeper voice and more hair, but it seemed to be moving the... opposite direction? Was that possible? A wave of hangover headache quickly disrupted his interest in revisiting bio class.
Still, the sight of his dad's naked backside, with Josh's cum dried along the spine, stirred some confusing feelings. How did his dad even end up here? Josh guessed it was the alcohol and years of this being his vacation bed, not the couch. As his dad began to stir, his body pushed against Josh's hard, nearly 8" cock poking through the fly in his boxers.
***********************************
Eric woke and the first thing he realized was he was hungover. His second realization was that he was not on the couch and there was a puddle of dried cum on the bed next to him. The third, perhaps most shocking realization, was there was a hard cock poking at his backside.
In a flash it all came back to him. Eric felt a rush of shame over the encounter in the middle of the night and, as tears came to his eyes, he tried to slip out of bed.
"Dad?" came a somewhat groggy voice from next to him.
"Josh I... have no words... the past 24 hours... you must hate me. I'm not sure what's going on but I have been a terrible father." Eric's voice broke as the words came out of his mouth and tears fell down his face.
What surprised him most was his son was pulling him back. Back up the bed and against him, a strong arm locking Eric in.
"Dad, I'm not sure what's going on either. But I love you. And there have been some weird things happening lately, but I could never hate you. Especially not right now. I'm too hungover."
Eric felt his son's soft, strong hands wiped away his tears. It had been a long time since he had been held like this and felt so safe. It felt so good.
It actually felt... too good. He realized Josh's cock was again pressed at his backside and his hole was almost involuntarily twitching. Josh's body was responding with small, almost barely perceptible movements of its own.
"Dad there's something about you lately."
"What do you mean?"
"I'm not sure. I just feel it."
"I feel something too."
