"Oh my God, Jake, I can't believe what you guys were doing last night!"
This was my opening gambit over coffee-making when the two of us had just got up. I was hoping my seemingly light-hearted quip might give me the opportunity to tell him I would really like to double-end with him - that being something one did with another man with an appropriate dildo. Not the sort of thing a wholesome and caring dad like me would normally ask of his son.
"Oh yeah," he smiled. "I thought you'd like seeing us playing with our toy. I take it you've never done anything like that before?"
He was wearing just a skimpy little pair of tight, white briefs. They showed his slim, athletic figure off quite stunningly and it was obvious that he had fully intended for the huge mound of his over-generous cock and balls to be so graphically flaunted.
I, only the other, hand was in a more decorous pair of boxer briefs. Tight enough to show off my bulge and bum but not as flagrant as what my son was flashing.
"No," I admitted, adding two mugs for Guy and me to join the two he'd already put out. "It looks like it'd be... well... pretty amazing, actually. Something I'd like to try for myself."
"Yeah, it's great for nights when both of us both fancy having something up our butts and neither of us wants to be... you know... the guy on top!"
I smiled, spooning coffee into the four mugs. "Does that happen often?"
He nodded, adjusting his briefs to show his cock off a bit better. He must be hoping that Guy would soon stagger downstairs.
He'd certainly flaunted himself at my regular bed-friend in the bathroom the previous night when the four of us guys had been brushing our teeth. I'd been appalled at the way he'd kept pretending to drop his toothbrush so he could bend over and push his skimpily-clad backside against the bulging mound of Guy's briefs. He'd kept giggling and apologising for such repeated 'accidents' and I'm sure he'd been about to try something more overt before he saw me glaring at him pointedly through the mirror.
He said, "Well, we've both got girls we're seeing, me more than him, and when you're with a girl you only really get to do it one way... you know what I mean...?"
"I think I vaguely remember," I smiled.
"So when you're with a guy," he went on, "you're kind of looking for something different. And having something dick-shaped shoved up your bum is pretty much about as different as it gets!"
"When the two of you were going at it together, it looked very... er... intense," I observed.
"Yeah, it is," he grinned, grabbing a couple of glasses for him and Marcus. "It was fifty quid well spent to be honest."
He took some orange juice from the fridge and filled up the glasses.
"I'd really like to have a go - maybe I could use yours to see if I enjoy it...?"
Jake nodded and put the carton back.
"You need two people, though," he said, waiting for the kettle to boil. "And I don't suppose Guy would up for doing something like that?"
"Of course not," I agreed. "And, to be honest, the position I had in mind would be based on what I saw you guys doing last night... the way that you were both enjoying it so passionately and were able to work against each other and add to each other's pleasure."
Jake smiled. He liked that I thought that he and Marcus looked hot together.
"Even if I could persuade Guy to give it a go," I went on, "the feel of it would be too unfamiliar for him to be able to relax into it like you guys were."
"So maybe Bradley?" he asked. "I reckon he'd be up for it!"
He threw me a smirk to suggest that if Bradley was indeed 'up for it', Jake would equally be up for watching the pair of us slapping against each other, panting and gasping as went at it butt-to-butt. Which wasn't totally unreasonable since he had allowed Guy and me to watch him doing exactly the same thing with his university friend the night before.
I spooned some sugar into Jake's and Guy's mugs. One for Jake, two for Guy.
"I was actually wondering," I began, hoping he wouldn't freak out, "and feel free to say no..."
He looked across at me curiously.
"... if you and I could try it together...? I think I'd really enjoy that..."
His curiosity changed quickly into surprise. Not shock, though, which was a positive.
"What, me and you?" he asked, making sure he'd understood. "Father and son doubling-ending it together? Going at it butt-to-butt with that dildo up inside us both?"
He grinned at me with amusement and I couldn't tell if he thought I was joking or if he genuinely found the idea curiously funny.
"That was pretty much what I had in mind, yes."
"Wouldn't it be bit weird, though?" he asked, his face becoming more thoughtful at the possible consequences for us. "I mean, I know we wanked off in front of Marcus the other night but -"
"Well, it would be kind of like that again," I explained as the kettle came to the boil and clicked itself off. "I was thinking that, if you were willing to try it with me, Guy and Marcus could watch us doing it. So it wouldn't be like it was anything serious."
Jake nodded and filled the cups up from the kettle.
He said, "So, let me get this straight. We'd be all be in the living room, me and you naked and going at it back-to-back, with those pair sitting watching us? Like we were the cabaret or something... Jake and his old man double-ending it for the audience?"
I saw from the way his bulge firmed up a little and poked outwards how much he was starting to like the idea.
"I think it would be quite... er... stimulating," I smiled. "And it's not like we'd have to touch each other so it wouldn't be like we were doing anything untoward."
Jake grinned and nodded. His cock was really starting to grow in his briefs. The mound it was making as it thickened and lengthened was verging on indecent.
"So we'd be sort of squatting together, or maybe on all fours, working our bums against each other, each of us helping to fuck the other with the dildo, but not actually touching? Is that what you mean?"
I nodded. And it really was exactly what I'd meant: was it so deeply wrong for me to have suggested this to him?
My cock responded, like Jake's, with a definitive no, developing a little in my boxer-trunks in anticipation of Jake saying yes. I was pleased my underwear was quite confining: I wasn't sure how Jake would respond if he saw his dad hardening up at the thought of us slapping our bums together in front of our house guests.
He wanted to clarify things yet further: "Okay, so when Marcus and I do it, we grab each other's bollocks underneath us when we're getting close. There'd be none of that with us two, would there? No reaching underneath each other to have a grope of the other guy's nuts?"
"Absolutely not," I said. "And I'm pleased that we've made that clear from the outset."
