Lucien didn't know that was possible!

Well he's having an educational evening.

Haru has nothing to rue but he could stand to punctuate the date a little more emphatically, if Lucien is not too overwhelmed so far.

He will have to show Lucien what he means by this.

There's several options!

Lucien does not actually have any clear idea what those options are, at all.

"I am pretty sure that uh. Behinds are involved. With at least one of them."

"A classic, yes, but I did not actually bring lube with me so we'd have to improvise."

"I assume that would make sense if I knew more."

"It's not advisable to skip it especially if you're not accustomed."

"Is that a specifically homosexual sex requirement?"

"No, straight people making use of the 'behind' as you put it have the same prerequisite."

"I didn't know they did that? I guess they are hardly excluded from the option."

"Less common, but, yeah, the ingredients are present."

"But there are other options that don't require additional materials?"

"As we have just demonstrated, though perhaps your mind was elsewhere at the time. Mouths also work."

"Oh I suppose that makes sense as an option."

Squirm.

"....An option which you would like?"

"If you don't have any other plans!"

"I have no other plans or idea how this is supposed to work but I am up for learning."

"You can probably extrapolate the major principles," Haru says, noticing that he still has underwear on and ceasing this foolishness. "Like no teeth, that's one."

Lucien blushes furiously when Haru removes his underwear and barely notices the teeth advice.

Well, that's fine, it's probably extrapolable. Does he need a minute to stare, Haru can be patient. A little.

He can recover his wits in a minute. 

".... It's strange how surprising this feels despite how it should be the case that this is more familiar to me then an opposite sex partner would be."

"Maybe that would also have been very surprising? You refer to it as though it has not come up in practice."

"It hasn't, I suppose it might have been, yeah."
