"By the way, if you dirty my clothes I'll rip out your balls."
Shizuo also believed her on this. Izaya leant next to Shizuo without being in his firing range, so to speak. He was almost as turned on by this but he had something called self-control which Shizuo clearly lacked. Which made toying with him so much better.
"Do you want to come?"
Shizuo nodded enthusiastically. Not even sex was this excruciatingly good. Izaya tsked, his tongue clicking loudly.
"How am I supposed to know if you don't tell me? And can I call you Shizu-chan?"
Shizuo could not see her all that well directly since she was no longer in front of him but there were mirrors all around that allowed him to admire her curves that the coat hardly concealed.
"…yes."
"Yes to what?"
"Both…make me come, please."
Izaya licked his ear and tugged his hard dick.
"How polite of you, Shizu-chan."
He stressed the last syllable by making it very raspy. Izaya moved his fist up and down and used his free hand to twist one of Shizuo's erect nipples. This was wonderful as it was but Izaya was not satisfied. So he produced a lipstick from a pocket and licked it. Then he added ghost gestures to Shizuo's buttocks and casually dropped,
"This may hurt just a tad so be a man about it."
And with this he unceremoniously pushed the lipstick past his anus and firmly into his body. Shizuo hissed and his eyes almost watered. Super strength or not, this was painful in more ways than one.
"That hurts…"
"So much for being a man. I am disappointed in you."
Shizuo swallowed and decided to endure it. After all, while it did hurt, his hard-on was unflagging and he was just as needy as before if not more. Izaya pulled the lipstick out then slammed it straight into Shizuo's weak spot, white pleasure unhinging his knees so that he slid down the wall until he was sitting on the floor.
"What- what was that?"
Izaya smiled wickedly.
"You need a few biology lessons. Mainly about the positioning of the prostrate. Now get on all fours like the mutt you are."
This was taking a risk, Izaya was aware of it, but nothing really worth gaining existed without a certain measure of risk. As it turned out, Shizuo was already far too gone to even protest and he obediently assumed the position. Izaya knelt by him and slowly pumped him as he worked the lipstick in and out. Needless to say he always opted for the long type of lipstick that could go all the way where it needed to go if needed. Impromptu dildos were a proof of his creativity.
"That's good- I had no idea-"
Shizuo could not even begin to put it into a coherent sentence. He wanted to fuck her, he wanted it so badly that it hurt but he had been beaten into submission so flawlessly that he did not dare even try it.
"How sad that you are so ignorant about your own body."
Shizuo pushed back, he needed the intrusion to hit him deeper. He rocked into Izaya's expert hold, moans that he did not even recognize as his, escaping his parted lips.
"All men are the same down deep. Shizu-chan, I'll let you come…if you kiss my new Prada shoes."
Izaya moved in front of Shizuo and displayed a pretty buckled high heel boot. For a split second he considered kicking Shizuo. But then lips were pressed on his shoe in a kiss and Izaya had to repress a fit of giggles. This was absolutely too good to be true.
"Good boy. I'll give you your treat, then."
Izaya got him on his knees and took his hard member into his mouth, pushing the lipstick as he did so. The wet warmth was too much for Shizuo's already tattered control to handle and he came in Izaya's mouth, releasing his full load inside and rolling his eyes as the hard tip inside him re-ignited his orgasm. While he was still panting, she locked lips with him and slipped him his own semen, all salty and mixed with saliva. Shizuo swallowed it without as much as a thought.
Izaya got up and wiped his lips from any traces of white liquid.
"You didn't expect me to swallow it myself, now did you? How vulgar. Get changed, I'll be back shortly. I have matters to attend to." These matters pertained to a certain tightness below the waist that had to be relieved soon. Izaya almost entered the men's bathroom but he did correct the mistake before it became drastic. He closed the stall's door behind him and worked himself fast. Not very ladylike but some sacrifices had to be made for the greater good. Izaya came fast and silently, milking himself for all it was worth and basking in a delicious afterglow for a while. He then wiped clean the remains of the deed, put on a new pair of panties since the old ones were a bit damp (he always carried an extra pair in his purse, just in case) and added some gloss to his lips. Izaya waited until he was as composed as he knew Anna would approve and then returned to the store where Shizuo was fully dressed but still blushing and dazed.
Izaya adjusted Shizuo's new clothes and paid for them while Shizuo mumbled something that did not make much sense anyway. Izaya was wondering what to do next when Shizuo spotted a very familiar face. Finally, here was an opportunity to prove himself.
"Kasuka! Hi there! Oh, this is my brother, the one I told you about. And this is-"
Izaya pulled Shizuo into a deep kiss, keeping eye contact with dear onii-chan.
"Orihara Izaya."
Shizuo blinked and looked around.
"Where?"
Kasuka deadpanned and pointed at Shizuo's companion. Shizuo blinked some more.
"I don't follow…"
This time around Izaya did burst out laughing in his typical Izaya-insane way.
"Oh dear, guess I just can't fool the smarter brother. Or is it the least dim? Same thing, really!"
With a flourish Izaya removed his sunglasses and smirked happily. Shizuo turned a sickish shade of ash-grey.
"Oh…shit"
"Indeed, Shizu-chan! I can call you Shizu-chan, right? Since we're on such intimate terms now? Besides, you told me you could just a while ago…and you're not fickle, now are you? Wait, you probably don't know what 'fickle' means. Just ask your brother, he should know."
Shizuo stuttered, blushed anew, stuttered some more than at length managed,
"You- you- Izaya, you fucking louse, I'm gonna kill you! Got that?"
"Yeah, yeah, so what else is new. No wait, having you on all fours while I fuck you with lipstick is pretty different from the usual routine."
Shizuo turned to his brother who remained as deadpan as ever.
"He's lying! Really!"
"Kasuka-chan, your big brother is more of a sub than anything else. Bet you didn't know that. And I got to him first. Shizu-chan, I'm almost family so I'm -chan'ing your dear brother as well!"
Shizuo tried a desperate measure.
"Kasuka, who are you going to believe? Your big brother or this flea maggot that is- a bloody louse!"
"Being redundant there, Shizu darling."
Kasuka added in his flattest tone which was very flat indeed:
"This is why I changed my name, Shizuo. Try not to embarrass me further. And Orihara-san, going after Shizuo is too easy."
"Kasuka!"
Izaya piped in unison.
"'Kasuka'! And now I must leave you wonderful siblings to sort out thing for themselves as it is almost 5 and my sisters expect me for tea. Oh and by the way, I got the security camera footage and I'll make sure the world sees it. I owe it to...mankind! Watch out, nii-chan. Shizu-chan has more talent than you and guess what! He has more than one expression! Au revoir, my Heiwajima pretties!"
Shizuo sobbed. He did not even have the heart to chase Izaya who left on a flashy red limousine that apparently he had at his beck and call. Shizuo could not win. That much was obvious. At length, Kasuka spoke.
"I guess it's true what they say. Image is everything."
And so it was.

The End.
