"Cisco," Lisa Snart spoke as she approached his table at Jitters, "I need your help."

Cisco opened his mouth. "We'll help you," Barry spoke, causing his companion to startle.

"Barry?"

"I'm a CSI now Lisa, I know just how much I owe you."

"All I did was make a phone call."

"And all I'm going to do is ask a friend to help you."

"Why are we doing this?" Caitlin asked Barry, keeping her voice low so it didn't carry to Cisco and Lisa in the next room.

"Because it's what we do?"

"That's not what I mean Bare, and you know that."

He blew out a breath. "When Iris and I were Juniors, there was a party," he stated. "We were invited by one of her classmates, but I didn't know until we got there that I'd been specifically invited, or that his older brother was organising it," he continued and she tensed. "There was a bit of an odd moment when we arrived; I thanked Jeremy for inviting me, and his brother said I was adorable, to which Jeremy responded 'I told you he was cute'," he narrated. "I didn't think anything of it at the time. Anyway, Lisa was there, and we had a bit of a chat, not much, she was just nice," he added with a shrug. "Well, it's a bit hazy after that, but someone put something in my drink, put me in some kind of vehicle and took me somewhere." He paused as he spotted how tense she was. "It's okay Cate, nothing more than happened, because Lisa had noticed and called Len." He met her gaze squarely. "They may not have the same morals as us, but after a five-minute conversation, Lisa spotted what was happening to me and rang the one person she knew with the skill set to get me out of it, and Len went into a dangerous situation blind to help a stranger just because his sister asked." He blew out a breath. "There's good in them."

She laid a hand on his arm. "I know why you feel the need to do this Bare, and I'll help you in every way I can."

"You broke my sister's heart," Len spoke and holstered his cold gun. Sirens rent the air.

"Go," Barry urged. Len's eyebrows rose. "That wasn't a choice I would have made, but I understand why you felt the need. I owe you a big favour, I'm not going to stop you." The sirens reached the outside of the building. "Screw it," he muttered and tapped into his speed, transporting himself and Len a safe distance away.

"You know that counts as Aiding and Abetting, right Scarlet?" Len drawled.

"Technically I already was – and while Central City seems to ignore it, vigilantism is a crime."

Len spoke an address. "Any chance you could get me there?" Barry grinned and tapped into his speed again. "You do come in handy Scarlet," Len drawled as they arrived.

"I'm just amazed you never feel sick," he remarked.

"Perish the thought." Another grin from the speedster. Len tugged off his hood and goggles. "For the record Barry, I was never going to cash in that favour."

Barry pulled back his cowl. "I know." He met the thief's gaze. "And I know that if you had found out what was happening to me from someone other than Lisa, you would have still helped me."

"Some things you don't do," he spoke firmly.

The Speedster smiled. "I'm going to do what I would have done then, if I had been coherent and brave enough," he stated and leant in, kissing Len sweetly.

Len returned the touch, keeping it light and his hands to himself. His lips curved as Barry pulled back. "Let me know if you ever want more than that Scarlet."

"Really?"

"I never make an empty offer – unless of course I know it'll be outright refused – but that doesn't apply here, does it Scarlet?"

Barry shook his head slowly. "How about I ditch the suit then join you?"

"Sounds good," Len drawled with a smirk.

Barry's smile was bright. "Oh, and for the record, I turned off my microphone before I told you to go, and I disarmed my tracker on the way over, so I'm the only one that knows this address."

"I can deal with that."

Barry blew out a breath, sprawled loose-limbed beside Len on the thief's bed. "I never thought I'd feel like this," he murmured, stretching his arms above his head.

"Relaxed?" Len drawled, gaze rivetted to Barry's bare, sweat-slicked form.

"Sated." A wicked chuckle from the thief. "You can laugh," he murmured as he snuggled into his companion's side. "You didn't gain a heightened libido along with a heightened metabolism."

"More of a gain than a loss, isn't it Scarlet?" he purred.

Barry shuddered. "I didn't think you could get a rise out of me." He sensed Len's smirk. "Pun not intended," he added hastily. He rubbed his cheek against Len's skin. "This is going to be a regular thing, isn't it?"

"Do you want it to be?" Len asked, stroking a hand up and down Barry's spine.

"You've ruined me for other men," he spoke flatly.

"Good," he drawled, letting his hand dip down to rest on his Speedster's ass. "This is completely independent of our arrangement."

Barry hummed agreeingly. "I trust you not to renege on our deal, even without this incentive," he murmured.

Len hummed before his lips curved in a wicked smile. "If I were to move my fingers," he drawled, "would I find you loose, or would you have tightened up again?"

Barry shivered with a soft moan. "Don't know," he panted.

"Want me to find out?" Barry nodded, and Len tipped up his Speedster's chin with his free hand. "I'll give you my number before you go," he stated. "Since I'm possessive enough not to want anyone else to touch you, I want to make sure you can contact me when you're in need of my company." His Speedster blushed. "You will ring me when you're feeling needy, won't you Barry?" he drawled.

"Or at least text you," he murmured.

"I can deal with that," he spoke as his dipped his fingers, pressing ever so lightly against his Speedster's hole, finding him wet but only half-loose. "Hmm, I'll have to loosen you up again before the next round." Barry vibrated. A wicked chuckle. "I told you we'd have fun, Scarlet," he purred and scissored his fingers, lips curving as the brunet pressed back into his fingers. "So deliciously sensitive," he purred, adding in a third once he was sure his Speedster could take it.

"Len," Barry whined.

"I don't care if you can heal any damage, I am not going to hurt you," he spoke firmly. Barry whined. "But I can speed up," he acceded. He soon had Barry prepped enough to satisfy himself. "Straddle me," he urged.

"But-"

"We know that if you vibrate it'll feel good for me, it doesn't matter to me how soon we reach the finish line Scarlet, just that we both reach it." Barry expression brightened and he shifted until he straddled Len's waist, the thief helping him to line up, before he sank onto the thief's cock. He let out a moan. "So full," he panted. "So perfectly full of you," he moaned.

Len's fingers splayed possessively on his Speedster's hips. "You feel perfect to me too Scarlet," he purred. "Move for me."

Barry rose and sank back down onto Len's shaft, speeding up as he got his rhythm going. Going faster and faster until he vibrated, sending himself and Len over the edge, his blurred form instantly stilling. Len gripped hold of him before he could topple, and gently eased him down, wrapping his arms possessively his Speedster, smiling at the pleased hum from the brunet. "I've got you Scarlet," he murmured, stroking him soothingly, mind conjuring image after image of what he could do to and with his Speedster-

"Len?"

"Yes Scarlet?"

"Would you still want me if I wasn't a Speedster?"

Len gently tilted up his chin. "I want you, Barry, not your superspeed," he spoke firmly.

"Did you want me when we met?"

"One, you were too young, and two, we didn't meet in the best circumstances," he answered slowly.

"Depends on your view, and that didn't answer the question."

"I was drawn to you, but even if we had met when you weren't at risk, I wouldn't have made a move."

"If I'd made one?"

"I wouldn't have let you go any further than making out until you were at least eighteen – I'd feel like I was robbing the cradle doing even that much." Barry lips curved. "I realise that's ironic coming from a thief," he spoke with amusement.

"At least eighteen?"

"Depending upon how mature you were," he answered honestly. "I was thinking of giving you a few years to grow up, then look you up…" he trailed off and lifted a shoulder. "Circumstances were against me."

"That makes me feel a little better." His thief's eyebrows rose. "All right, the reason I didn't get that far in experimenting was because I kept asking myself 'do you trust him as much as you trust Len', and when the answer was no, I nipped it in the bud." Len opened his mouth. "Obviously that wasn't that much of a spark, or that would have overridden the thought."

"I was just going to say that was sweet…and I can't blame you for putting me on a pedestal since I saved you."

"I didn't put you on a pedestal, I was aware enough to know that you weren't law-abiding when you saved me, I just knew that you had lines you wouldn't cross, one of which involved not hurting me."

"Like I said, some things you don't do."

"My gentleman thief," Barry murmured, and shifted close to kiss him sweetly.

Len huffed. "Please don't say that where anyone else can hear you."

"Promise," he replied with a bright smile and snuggled close. "Do you have plans for tomorrow?"

"None that are pressing, what about you Scarlet?"

"Day off."

Len's smirk was wicked. "I'll be sure to keep you entertained."

"Sounds good," Barry breathed with a shiver, looking forward to it already. He got the feeling that he would be insatiable where Len was concerned, and he was pretty sure that his gentleman thief wouldn't mind in the slightest.
