Summary: Something has happened to Ianto.

***

Jack keeps looking at Ianto like a hungry wolf, devouring him with his eyes. It makes him uneasy, to have that *focus* on him.

It's not unusual to have Jack's eyes on him; he's used to *that*, at least. It's just a singular focus, like - if they were alone, Jack wouldn't hesitate to throw him up against the wall, to take him *there*.

He's used to Jack wanting him, but not this.

Jack grins at him and turns back to his paperwork, toying with a pen in a way that sends shivers down Ianto's spine.

His suit is too big for him in the shoulders, and his pants hang strangely, baggy in places that he's not used to, clinging in others. He's still tall, skinny, but now he feels softer. It's... strange.

Jack turns on the comm, practically purring. "Ianto, would you come up to my office?"

"Would you like some coffee, sir?"

"No, Ianto, that's not necessary," Jack replies, and Ianto can hear the grin over the line. He puts down the papers he'd been sorting; walks up the stairs numbly.

Jack's pacing the office. "I sent the others home early, Ianto."

"Sir?"

"It's going to wear off in a few hours, right? So..."

"Four hours, 36 minutes, 24 seconds, sir," Ianto replies automatically, pretending that the smile isn't sending heat straight down his spine in waves. Jack just grins, crowding Ianto towards the wall.

"Now, Ianto. Don't you think you should call me Jack?" He brushes his thumb along Ianto's lower lip, and Ianto's mouth falls open under the touch.

"Yeah," Jack says softly. Ianto moans. Heat pools in his belly, in his hips. "Yeah, Ianto."

Jack replaces his thumb with his lips, then, kissing Ianto with a ruthlessness, a *need* that just resonates deep within Ianto. He moans again as Jack pushes him against the wall, pushing into him.

"Jack!" Ianto hisses as Jack's mouth moves to Ianto's neck, sucking and biting. Jack's hands move to Ianto's pants, unbuttoning and pushing inside, and then -

"Yan," Jack pulls back to grin at him, eyebrow raised in curiosity.

"They're - Gwen got them for me, because..." he trails off, embarrassed. His shorts hadn't fit right; it was uncomfortable. They aren't anything fancy, but Jack looks like they're the sexiest thing he's ever discovered. Of course, Jack regularly looks like that during sex, but - GOD!

Jack's fingers are practiced at this too; rubbing against him just *so*, and Ianto bucks helplessly at the touch, shivering and mewling. "So *wet*, Ianto," Jack whispers. "God, Yan."

Ianto sobs and rocks against Jack's fingers as they slip past the crotch of his panties, and then Jack's fingers are *inside* him, and it's different than anything Ianto's ever felt before, so *good*; he can't help but clench around them and jerk and come for what feels like *hours*.

It's not hours, not really, hardly any time at all, and Jack kisses him again, and, "Yan," Jack whispers against his mouth. "Yan, please, I-" Ianto's hands are shaky, but it's not hard to undo Jack's flies, to reach in and touch him. Jack's so hard, blood warm and practically throbbing in Ianto's hand as he slips Jack's cock out.

With his new hips, it's easier than usual to shimmy out of his pants; his shoes hadn't fit anyhow, so he's been barefoot all afternoon, and they just slip right off. The panties are a different matter, but Jack reaches out and just *tears* them off. Ordinarily Ianto'd be worried, but they're cheap, from a three pack, and it's not like he'll be needing them for more than the rest of the night. Jack lifts him like he weighs nothing at all, and just *slides* in.

"Oh," just slips out of Ianto's mouth, and then Jack thrusts into him, and then again, and "oh!" Ianto says again, intelligently.

"Yeah, Ianto, yeah, God, so *good*," Jack breathes, and kisses Ianto again. Ianto wraps his legs around Jack's waist, and Jack fucks him with shaky rhythm, hard and fast. Ianto feels every stroke building pressure inside him again.

"Jack," Ianto groans, tipping his head back. Jack sucks on Ianto's neck, bites at Ianto's shirt, and comes in a rush of heat inside him. He shudders and thrusts involuntarily, slowly and shallowly, and it's just enough to send Ianto over the edge again.

Jack's still inside him, his head propped against Ianto's shoulder as he gasps for breath. Ianto isn't much better, petting Jack's shoulders absently.

"God, Yan, that was -" Jack doesn't finish, just grins up at him. Ianto smiles back. Then Jack's grin gets broader. "How much time did you say we had left?" Ianto groans; Jack's going to kill him before the alien drug wears off.

"You haven't even taken your shirt off!" Jack adds. Ianto hits him.
