"So... onto the first consummation," I suggested, pausing for the two men to reposition themselves and sit alongside each other on the couch. "In this painting, Adam is... er... making love to Stephen. Am I okay to describe it like that?"
I'd expected Adam to haughtily inform me that one man doesn't make love 'to' another but rather that their sex is collaborative and their love fully reciprocal. Or some variation on that general theme.
But instead Stephen giggled and surprised me by blurting out, "Oh come on... can't we just call it 'butt-fucking'? I mean, that's what we're going to do... fuck each other's butts."
"Sweetheart, we're talking about our wedding night!" Adam cooed. "It's our special joining... the fulfilment of our vows!"
"Yeah, I know... and it's going to be a really amazing experience for us both. But ultimately, you're going to fuck me up my arsehole and then I'm going to fuck you up yours. So why not just cut to the chase and call it what it is?"
I suppressed a chuckle. I was so pleased that Stephen had opened this can of worms rather than me.
"You make it sound crude," Adam argued. "It's a very beautiful moment... the connecting of our bodies."
"And it still will be! I'm just suggesting that when we're describing to Michael how we want him to paint the two stages of our consummation, it'll be quicker and clearer if we just say which of us is fucking the other up the bum!"
"It would indeed be rather less confusing," I chipped in. "Referring to it as your 'special joining' and 'anal union' is very poetic, but I would appreciate a little more clarity."
"Very well," Adam nodded. "In that case painting four is to show me fucking my new husband up his rather gorgeous butt."
Stephen chuckled. "So Michael... I don't know how much you know about gay anal sex...?"
"I certainly wouldn't claim to have an encyclopaedic knowledge," I admitted.
"Well, to get my bum used to Adam's cock, we have to start out looking kind of... well... inelegant, I guess you might say..."
"Inelegant?" I asked. Was this going to be something about shit again?
"Yeah... I need to loosen up... relax my muscles to receive him..."
"Oh, I see," I muttered, not really seeing at all.
"I have to squat really low and push my bum right back," Stephen explained, standing up and bending almost double so that his arsehole was yawning open like the mouth of a deep dark cavern. Adam stood up behind him with his big cock looming forwards towards the hole that his fiancΓ© was so immodestly offering.
He went on, "Adam will enter me in this position until my backside is used to his length and girth. Then we'll get on the bed together and make love properly."
Adam nodded. "It takes about a minute and is fairly standard in same-sex coitus when the man penetrating is... well... as generously endowed as I am."
"I see." I wouldn't like having to go through a palaver like this every time I fancied a shag.
Stephen smiled up at me, still bending so low that his face was going purple. "I'm just telling you this because we really don't want you to paint us having sex like this. Some men like the position but for us it's purely functional."
I asked, "So how is this... er... 'pre-fuck'... if I can call it that... different from your love-making? How will I recognise the part you want me to depict in the painting?"
"The two things are completely different," Adam snapped. "Our actual consummation will express our love and our passion."
"Perhaps it would be clearer if you show me," I suggested, thinking they would get on the couch together and pose for me their more sensual way of making love.
But Adam interpreted my request differently and nodded, "Well, I suppose you might as well see it sooner rather than later."
He stepped forwards, grabbed Stephen firmly by the hips, and then to my amazement started pushing the head of his huge hard-on into his bent-over buddy's butt-hole.
"It resists a little at first," he told me, as matter-of-factly as he would if he was showing me how to screw a nut onto a bolt, "but once the fat tip of it's through, the shaft generally slides up nicely."
Stephen gasped, "Aw yeah..." as his arsehole stretched at full gape to receive his future groom's bloated helmet.
"This is why the rimming needs to be very thorough," Adam smiled at me as the ridged base of his mushroom slurped through Stephen's straining ring. "It not only excites us both, but it means one doesn't have to hunt around for a tube of lube."
Adam's long shaft performed as he'd indicated and slid more easily up into his fiancΓ©'s bowels now that the head was inside.
Stephen called out, "Oh Jesus!" and then let out a powerful fart.
Adam chuckled, "You should expect some very boisterous flatulence when two men are occupying the matrimonial suite!"
I managed to mutter, "I hadn't really thought -"
"With your navy background," he went on, still sliding his cock up Stephen's arse, "I'm sure you're not offended by a good, loud man-fart!"
"I just never heard one during sex..."
"Well you'll hear some absolute blasters on our wedding night!" he chortled. "It will signify to our guests in neighbouring rooms that the consummation is underway!"
"It's also one of the reasons for the 'pre-fuck', as you called it," Stephen panted breathlessly up to me as his butt let out another rip-roarer, struggling to accommodate the huge intrusion. "It gets the unpleasantness out of the way before we make love properly."
"Farting isn't unpleasant, honey!" his husband-to-be laughed. "It's a celebratory trumpeting to announce our love-making!"
"Adam likes a noisy blow-out when we enter each other!" Stephen grinned at me. "It makes discreet sex when we're staying over with friends just about impossible!"
"Okay, so I just hold him by the hips," Adam said, returning to showing me how he loosens Stephen's bum up, "and start sliding slowly in and out."
He withdrew a good six or seven inches of his cock from his companion's arse and I saw what he'd meant earlier when he'd referred to 'a certain amount of smearing'. He drove it slowly back in and Stephen let out another extremely loud fart.
"Bend lower, sweetheart," he muttered to his betrothed. "And open your legs wider... let me grind you a little..."
