Contracts with Demons Are Foolish! (4)
A beauty with blue hair and golden eyes. It was Tsuna, a gano of the Orpen household just like Rina. Three years Rina's senior, she was another who enjoyed the Viscount Orpen's special favor. She was also the only female gano Rina truly opened her heart to.

"Hehe, Rina. That look on your face—you're hiding something right now, aren't you?"
Rina quickly shoved Purpur's letter behind her back. But she couldn't quite hide her flustered expression.

"N-no, nothing like that."
"Rina, it's written all over your face. Come on, tell your sky-like big sis what you're hiding."
Tsuna grinned mischievously and lunged at Rina. Rina twisted desperately to keep it hidden, but Tsuna—being taller—pinned her down in no time.
"Let's see what Rina's hiding~"
"I said no, sis!"
Tsuna smirked slyly as she grabbed Rina's arm and lifted it high. Knowing she was caught, Rina squeezed her eyes shut.
"What? There's nothing here! Rina, are you messing with your sky-like big sis?"
"Huh...?"
The letter was definitely in Rina's hand. Yet Tsuna hadn't noticed it at all.
'Is there magic on the letter? Thank goodness. Let's play it off naturally.'
Rina casually slipped the letter into her pocket and grumbled.
"I told you it was nothing, but you went charging in with your assumptions."
"Hehe... I totally thought you got a love letter and were secretly reading it."
At the words "love letter," Rina's cheeks flushed faintly.
"As if I'd get one of those! And anyone who tries that with me gets kicked out anyway."
Rina had received plenty of love letters in her life—not just letters, but confessions too, coming regularly. From fellow gano her age, loyal retainers, even esteemed guests visiting the estate. Each time, Viscount Orpen personally intervened, blocking every man who approached her. Gano were sold off to hellish places, retainers got scolded and fired, and guests faced his blatant displeasure as he drew a hard line. His stance was utterly uncompromising.
"Still, the summer coming-of-age ceremony is next week. You never know—a dashing hero might show up to overcome adversity for love."
"Hmph, like any guy in this house would."
Rina shook her head, thinking of the male gano and retainers working the estate.
"Hmm... What about Leon?"
"That shy, bashful Leon who looks tougher than he is?"
Leon was a male gano Rina's age. They'd been close friends once, but lately he got all flustered around her, unable to meet her eyes like the timid boy he was.
"But he's tall and sturdy-looking, so lots of girls like Leon."
"Ugh... That's not for me to know. Besides Tsuna sis, I don't have any real friends among the girls my age anyway."
Rina puffed her cheeks with her usual little whine. That jogged her memory of the incident with Rozette, momentarily forgotten amid the Purpur business. The female gano who'd beaten her mercilessly and then badmouthed her behind her back instead of helping—it made her heart ache. Tsuna must have known, because she dropped her playful expression and gently stroked Rina's hair.
"I heard Rozette hit you again. Must've hurt a lot."
"Ugh... I just greeted her, and she picked a fight over it and beat me."
"Rozette's been sensitive lately with the marriage talks. Be careful for a while, Rina."
"Marriage? Oh... that pervert count?"
Nobles usually got engaged before their coming-of-age ceremony. Rozette, daughter of a viscount house, was no exception. She'd long since had her engagement ceremony with Count Mortaine. Rozette despised the match. For one, the count was well past forty. Wide age gaps were common in noble marriages, but no young lady like Rozette would welcome a lecherous old man. And Count Mortaine was infamous for his sadistic perversions. The rumors were so bad that his previous wife had supposedly killed herself from the shame of his twisted demands. Rozette threw tantrums demanding to break it off, only to get a harsh scolding from Viscount Orpen.
"Hmph, but isn't that just rich-kid whining?"
Rina judged Rozette's rebellion coldly.
"If you're born a noble, you bear that duty for your house."
Erina's world flashed in her mind, plunging Rina back into gloom.
'Some nobles are born slaves...'
Meanwhile, Tsuna clapped as if in full agreement.
"Totally! Even if Count Mortaine's as pervy as the rumors say, he wouldn't do that to Rozette, right?"
"Exactly, Tsuna sis. Even a perv like that would only do those things to seongnoye."
Tsuna's face lit up with mischief again at Rina's words.
"Hehe, like our master? Speaking of, next week you'll be a seongnoye for the master just like me, Rina~"
Rina's face turned beet red.
"Wh-wh-what are you talking about? I hate that stuff!"
"Rina, you don't get to say no. Don't be scared."
Tsuna playfully licked Rina's nape.
"Your big sis will teach you everything so you don't get punished by the master."
"Ah, seriously, sis!"
Rina tried to shove the teasing Tsuna away, but Tsuna clung stubbornly.
"Such a cute reaction—you've got talent— Heut♡!"
"S-sis, what's wrong?"
Tsuna suddenly pulled away from Rina, hunching over. Her face flushed deeper, her breathing visibly ragged.
"Hehe...♡ Hehe...♡"
"Sis, are you hurt?"
"Huh? N-no, I'm fine... Oh, right. Rina, how's the spot where Rozette hit you?"
Tsuna asked the question while panting lewdly.
"Huh? Oh... She slapped my hand and cheek, but the swelling's gone down."
"Good. Sorry, Rina, I've got an errand. Catch you later."
Tsuna staggered off awkwardly.
"What's up with sis? Is it that time of the month?"
A little later, in Viscount Orpen's bedroom. A beauty with orange hair lay passed out on the bed, covered in semen. Viscount Orpen sat naked before her, fiddling with his grotesquely obese cock.
"Tsuna, did you meet with Rina?"
Tsuna stood respectfully before the bed. Her face was deeply flushed, her breaths beastly and rough.
"Hehe...♡ Yes, master. She got slapped on the hand and cheek by Lady Rozette, but thankfully it wasn't bad."
"That Rozette girl tormented Rina again? Tsk... Was Rina crying?"
"Uhuh...♡ I thought she would be, but no—she had this... strange expression."
"Is that so? Good she didn't cry. Come closer."
As Tsuna approached with effort, Viscount Orpen slapped her breast hard from his seat.
Slap!
"Heak...♡ Too rough, master... Be a little gentler..."
At Tsuna's backtalk, Viscount Orpen slapped her breast again.
Slap!
"Heu~♡ So mean!"
"No lip. Strip."
"Hehe♡! Sorry, master."
Tsuna's trembling hands began undoing her gano robes. As the sweat-soaked fabric slid off smoothly, her full breasts asserted themselves against her pale skin. Large golden ring piercings adorned each nipple.
Viscount Orpen hooked a finger into the right piercing and yanked roughly.

"Heut♡! Nipple! My nipple's gonna rip off!"
But far from resisting, Tsuna clasped her hands behind her head, arching to make it easier for him to pull.
"Heuut♡! It hurts! Just a bit more... just a bit more and...!"
Viscount Orpen ignored her pleas and let go. The taut piercing snapped back elastically.
"Ah, no... I was so close this time..."
"You bitch in heat. Pants off, now."
"Y-yes~!"
Panting, Tsuna lowered her skirt. A sturdy metal chastity belt hugged her hips, a faint mechanical hum vibrating from within.
"How's the chastity belt feel?"
Tsuna clasped her hands behind her again, thrusting her crotch forward in supplication.

"Please unlock it, master. This evil chastity belt... I wanna cum so bad but I can't..."
Viscount Orpen pressed a switch.
Vrrr—
Strong vibrations erupted from Tsuna's chastity belt.
"Heuuk♡! Turning it on so suddenly...!"
Tsuna lost balance from the intense stimulation and collapsed into Viscount Orpen's lap.
"You didn't let Rina notice, did you?"
"Heu...♡ I gritted my teeth and held it in. I did good, right? Uhuh~♡ So please let me cum this time!"
Viscount Orpen spread his legs, thrusting out his hideously erect cock.
"I'll decide after I see you suck it."
"Hehe♡! Yes! I can suck really well."
Tsuna lunged at his cock like she was entranced.

"Churp... Heu...♡ Churp... Heuk...♡"
Viscount Orpen stroked Tsuna's head in satisfaction.
"Rina must be defiled by this viscount himself. Of course. How long this viscount has endured, waiting for this moment... Mmm..."
Viscount Orpen savored Tsuna's skilled tongue and throat, lost in ecstatic fantasy.
"Ahh... Serena. I couldn't have you in the end, but your daughter... I will make her mine. Hahaha!"
