While the sex I'd had with my son had been tender and passionate, the turn he'd insisted he had on me had been anything but.
We'd had a few drinks together and endured a very awkward conversation in which my claims that Jake had been complicit in our misdemeanours of the previous evening - that he had in fact drunkenly seduced me - had fallen on resolutely deaf ears.
"I told you this morning, dad," my son had snorted sullenly. "What you did to me, I wanna do to you."
"And then you'll feel we're even?" I asked him, topping up my wine from the bottle to help benumb the very difficult encounter that was awaiting us both.
He'd nodded glumly, taking a swig from his own beer.
"Obviously, I let things go way too far last night," I admitted to him slouching on the armchair. "But what you're about to do is hardly comparable."
"How d'you mean?"
"What happened last night was very much in the heat of the moment. This seems... well... horribly premeditated."
"It's not ideal," he shrugged. "But then it wasn't ideal of you to fuck your own son up the butt."
"I've told you repeatedly, Jake... you were urging me on... you even splayed your cheeks and called your anus your 'cunt'."
"I was drunk," he shrugged. "I didn't know what I was doing."
"Well, I'm drunk now," I said, standing up and picking up my wine glass. "Do you want to get this over with?"
"It's as good a time as any," Jake nodded, his expression nonchalant as if to make clear that this was a chore rather than a pleasure.
He followed me upstairs and we went into my bedroom.
Jake started unbuttoning his shirt so I asked, as I sat down to take off my shoes, "Do you want us to both be naked for the... er... act?"
"Yeah," he agreed. "I want you on your bed facing forwards so I can kneel behind you and grab onto you by the hips. Then, basically, I'm gonna bum you really hard until I cum a massive wad up your arse."
"Don't you want me from the front... that's how I did it to you?"
He shook his head resolutely. "I don't want it to be nice."
"Well, I'd better use the bathroom before we start. You're a very well-endowed young man and I should make sure I'm ready to receive you..."
"No," he said flatly.
I peered across at him, surprised by his reaction. He glared dourly at me and muttered, "Like I said... I don't want it to be nice."
We continued undressing in silence until we were both fully naked. Then we stood in front of each other, our two large father-and-son cocks hanging long and floppy over the top of our well-stocked nuts.
Jake was athletic and young; I was more chubby and my midriff was becoming decidedly middle-aged. His chest was hairless and his pecs prominently defined; mine was more furry and, while still quite bulked, I lacked the gym-sculpted musculature of my son's impressive torso.
There was little more than twenty years between us but I realised I was starting to let myself go.
"You really want to do this to me, Jake?" I asked him.
"No I don't, but I think I need to... then we can move on."
I got on my bed and bent forwards to present my two large round buttocks to Jake as he climbed on the bed behind me. I opened my legs wide so that my two big bollocks swung low and pushed my backside towards him to make my hairy crack splay open.
He'd seen my bum-rug before but I still cringed with self-consciousness.
I muttered, "I'm sure you've had sex with much more attractive bottoms than mine."
He shuffled up behind me, wanking his huge cock to get it hard, and said, "Yeah, but I've shagged worse ones too. For an older guy, your arse is actually okay."
I smiled, finding it unlikely that this was flattery given that he seemed determined that his payback should be as humiliating for me as possible.
He kept jerking his dick and it slowly stiffened up in his hand, and he asked, "Where's your gash? Is it low down like mine?"
I reached back and pointed to where my anus was lurking among the thicket.
"It's here," I said. "Enjoy the fuck."
Once his big cock was hard and curving upwards, he hocked a thick gob of phlegm up from his throat and spat it down onto it. He smeared his mucus around his plum-sized helmet and worked it down the thick girth of his veiny shaft.
Then grabbed me by the hips and started trying to push the enormous thing into my bum.
"An inch or so lower, Jake," I advised him, and then, "You might need to angle it upwards a bit..."
He slippery bell-end popped through the puckered ring of my hole, making me gasp and call out, "I might need some lube..."
He held my hips tighter and strained to work more of his enormous phallus into me, grunting, "You said you needed to take a dump... the shit you've got up your arse will be lube enough..."
Bloody hell, I thought. The lad certainly knows how to make a guy feel like dirt.
He reached up to my shoulders and clung onto them as he heaved inch after inch of his erection inside me. It pushed deep up into my hot rectum and then forced its way through the clammy resistance of my turd. He kept going, making me gasp as my sludge was squeezed around the blunt battering head of his cock, and then I let out a loud fart to which he responded, "Aah yeah!"
Once most of his manhood had been forced inside me, he returned his hands to my hips to hold me firmly in place for the butt-fuck, and said, "Right, are you ready for this? This is gonna be very hard and very rough..."
I peered back at him over my shoulder and asked, "Do you really feel you need to do this, Jake? Brutally sodomise your own father...?"
