Sarah pussy was already soaked from Lucas's teasing, and this sudden assault caused the pleasure she had been accumulating to burst forth like a flood breaking through a dam.
Her delicate neck arched high as she let out a loud, wanton moan. Her first orgasm had arrived so abruptly.
"Master just inserted it, Sister, how are you already climaxing?"
Lucas reveled in the sensation of being tightly enveloped by the ice beauty's pussy while ruthlessly thrusting without restraint.
"Could it be that Sister did this on purpose? Were you actually looking forward to this? To licking Master's cock together with your little Celes? To swallowing Master's cum together? Later, I'll press Celes on top of you, have your tits pressed against hers, your slutty pussies rubbing together, and then… fuck! Sister, your pussy is clamping down even tighter!"
Sarah's back was pressed against the door, her ass lifted by Lucas's hands, while her legs instinctively wrapped around his waist.
This suspended position made her feel insecure and mentally tense, causing her pussy to become far more sensitive than usual.
As Lucas whispered those humiliating, filthy words into her ear, she could only respond with continuous moans under his violent thrusts.
She couldn't even retort, and her pussy involuntarily contracted and quivered, bringing waves of pleasure to both of them.
"…Nnh~ ah~… ah~… ah~… ah~… ah!" After nearly a hundred forceful thrusts, the unprecedented pleasure made it impossible for Sarah to suppress her moans.
Every deep thrust from Lucas was met with a high-pitched, lewd cry from her. Soon, a second orgasm arrived with unstoppable force.
Sarah dug her nails into Lucas's arms, her entire body trembling as she let out a scream of ecstasy, gushing a flood of warm fluids that dripped from their joined bodies onto the floor with a lewd splattering sound.
Hearing such obscene noises, Sarah's entire body flushed pink. Her eyes were tightly shut, as if unwilling to face the reality of her climax.
But how could Lucas let her off so easily? With a forceful tug, he pulled back while still holding her on his cock.
Without the door supporting her back, Sarah instinctively wrapped her arms around Lucas's neck, leaving her entire delicate body hanging off him.
Lucas smugly bounced her lightly up and down, making her pussy swallow his cock repeatedly as he walked around the room.
This humiliating position made Sarah's moans carry a hint of sobbing.
"…No… take me to the bed… Master… please, Master… take me to the bed…"
"Wherever I fuck you is the bed!"
Lucas ignored her pleas, but the distraction of walking while thrusting made him pause in front of the mirror embedded in the wardrobe.
He forced Sarah to look at her own reflection—her lewd expression as she was forced to ride his thick, dark cock up and down.
"Sister, look at yourself. What do you think little Celes would say if she saw you like this? Maybe she'd be so jealous she'd strip naked and join us right away…"
"…No—!" The degrading words filled Sarah with shame, yet her pussy responded with rhythmic contractions, gushing more fluids.
Finally, as pleasure peaked, Sarah trembled violently, her climax spraying out as she let out a desperate scream, tears streaming down her cheeks.
The bet was over, but Lucas hadn't cum yet. He granted Sarah's request to "go to the bed," laying her down flat before pressing his body atop hers.
His cock found her entrance and slid in smoothly. This time, his thrusts were unusually slow and gentle, and he kissed away her tears like a lover.
"Sister, you lost," Lucas said softly, his tone threatening. "You have to honor the bet. Otherwise, I'll punish you…"
Sarah's body stiffened, her pussy clenching around his cock. The ice beauty forced a weak smile.
"…Fine. This little bitch understands. This little bitch will offer Celes to Master… hoping… hoping Master will be gentle with her…"
"As long as you both behave, I'll naturally be gentle." The image of Celes's perfect, long legs flashed in Lucas's mind, making his cock swell even more.
His thrusts turned fierce again, and after dozens of powerful strokes, he released his third load of cum deep inside Sarah's pussy.
About half an hour later, Celes finally arrived with the desserts she had prepared. By then, the siblings had cleaned up the room, though the faint scent of sex still lingered.
As soon as Celes stepped inside, she caught the musky odor and frowned slightly. Fortunately, her inexperience kept her from recognizing it. Sarah quickly distracted her.
"Celes, what did you make? Let me try it."
Celes's creation was presented on a tray in three identical glass bowls. The main component was a yogurt-based white fluid, topped with fruits, shaved ice, and other garnishes.
The taste was decent, though Sarah ate with a forced smile due to her conflicted emotions, while Lucas and Celes enjoyed theirs.
"This is delicious, Celes. You're quite skilled," Lucas said with a grin. "Do you cook often?"
"Of course not!" Celes shook her head like a rattle. "This is the first time I've ever stepped into a kitchen!"
Sarah asked softly, "Why did you suddenly want to make dessert?"
"…Because…" Celes's face flushed slightly, and she stuffed a big spoonful into her mouth, mumbling, "…Because you've seemed down lately, Sarah. They say sweets make people happy, so…"
Realizing Celes had done all this just to cheer her up, Sarah was overwhelmed with guilt. She was about to drag this bright, dependent girl into hell with her.
Emotions of gratitude, shame, regret, and heartache surged, making her eyes redden.
Celes, still shy from her confession, didn't notice Sarah's distress, but Lucas did. Worried Sarah might do something reckless, he decided to act immediately, using the Aphrodisiac Incense (Low Grade).
Celes's eyes glazed over as she mumbled, "So sleepy…" before slumping onto the table, unconscious.
