Gabe walks around and sandwiches Ari between himself and Henry. He removes his own shirt and then takes a turn kissing Ari.

Excellent. (Ari was kind of hoping to see the pornography first, but he is by no means disappointed by this turn of events.)

He kisses back enthusiastically. This is a technology his world has already developed, and Ari is a devoted student of it.

(There was probably some terrible communication misunderstanding. Or maybe, Ari is just that hot. A mystery for the ages.)

The cousins approve of Ari's studies. They pull Ari out of the kitchen.

They might be losing bits of clothes along the way. And helping Ari doing the same.

Ari is wildly appreciative of this assistance, as the cousins can probably determine from the state of the hose under his tunic, which are stretched around a sizable, leaking erection. He moans slightly into Gabe's mouth as he gropes the pair of them in turn.

That doesn't surprise Henry that much. The lifeforce analysis is sufficiently telling. But seeing it is another thing he takes a moment to quietly Gabe's attention to it.

Ooh, best day. Then, with possibly-supernatural luck, they pull off the maneuver of bringing Ari into the hallway, by the stairs while pulling Ari's pants down.

Henry strokes Ari's sizeable penis while the two cousins guide him upstairs.

Ari cooperates with the relocation, graceful despite the silk tights now halfway down his thighs.

He attempts to reduce his compatriots to the same state, but is stymied by their flies. He doesn't appear to have encountered the concept of the button-fly at any point.

Poor medieval boy. They can pause by their bedroom's door to show how it's done. Gabe undoes Henry's and reveals red briefs. Also quite tent around a large erection, thought not as leaking.

Maybe Ari wants to the honors for Gabe?

Ari's a quick study. He undoes Gabe's button and unzips him slowly, savoring the suspense.

Gabe is wearing something in almost neon blue. There is a band around his waist, supporting a pouch and there are two more bands connected to the waistband and going to the back. Gabe's dick is bulging against the flexible pouch, producing a spot of dark blue where the pre-cum is accumulating.

Henry spins Gabe around to show the backside nicely framed by the elastic blands. He then slaps a hairless butt cheek. Which causes Gabe to produce a delighted sound.

Well, that's practically an engraved invitation. Ari parts the cheeks and starts licking at Gabe's hole.

Ari is the best interdimensional arrival ever. Gabe will express this through loud moaning.

And how does the interdimensional arrival reacts when Henry copies his idea?

Positively! Ari gasps and bucks his hips back semi-involuntarily, burying Henry's face in his ass even as he thrusts his tongue further into Gabe's.

The cousins lose their last bits of clothing, except for Gabe's jockstrap. Gabe makes some incoherent noises and starts stroking himself with one hand.

Henry's face emerges from where it was buried. He replaces with a playful finger. "Let's actually get into a bed proper."

He opens the bedroom's door with one hand without breaking contact with Ari with the other.

The bedroom is a fairly two-young-adult-males-bedroom. It contains mysterious mechanisms, but more importantly: It contains a bed.

Ari will reluctantly withdraw his own face, in the interest of a bed.

Once on said bed, he traces a rune in the air with his fingertip, which begins to glow. "This is going to tingle a bit," he tells Gabe. "But you're going to like it."

Gabe is shivering in anticipation.

Ari licks his finger, shivering with delight, and inserts it into Gabe.

It's immediately obvious that electricity is involved with this somehow; the finger buzzes and pops inside him, tingling and giving off sparks of a sensation that's almost-but-not-quite pain. The main effect, though, is that Gabe can feel his muscles relaxing. His defenses fall open around the intruding finger, leaving his ass open and twitching.

Then Ari withdraws his finger and retrieves a vial of white oil from his belt. He smears it over his cock and gives it a few strokes. "Ready?" he whispers.

As the effects course through him, Gabe can't help but think how he is at hands of a complete stranger with unknown magic who he might not be able to defend against.

It's fucking hot. Gabe moans loudly and lets his muscles relax into a flat pile over the bed. He barely manages to perk up his butt invitingly.

"Our guest asked a question, Gabe," Henry says amusedly. He is still playing with Ari's hole but has also reached out for a lube by the nightstand and is applying on himself.

"Yes!" Gabe manages to say.
