The pressure only increased as Luna shoved in deeper. "Our boyfriend." Her gloved fingers twisted the toy for cruel emphasis. "Tell me, then. How do you think Aria will feel once she learns you tried to get ahead of her like this?"
Hearing that statement, strength mysteriously returned to the Space Valkyrie as heat from perceived injustice began rising in her chest. Defiance began boiling up through her whimpers. "Oh, please! Don’t you dare make me the bad guy here! Aria keeps doing everything to get ahead without asking either of us first! She’s the greediest, most unfair girl I’ve ever seen! So why should I play fair?!"
Her tear-bright eyes snapped up toward the mirror, finding Luna’s reflection and sending it a blazing glare. "And what about you?! Why are you even mad, huh?! In the forest dungeon, you said you’d never let Kaiden take your ass, that his cock’s too huge for your body. So what gives?! I don’t owe you explanations! I can get my butt fucked by my boyfriend whenever I damn well want to! I don’t need your stupid pre-approved stamp to do so!!"
Luna’s hand pressed firmly on the base of the dildo, forcing it in again with calculated cruelty. Then, without warning, her movements abruptly stopped.
Nyx blinked in confusion, panting heavily. She saw something that made her forget the anger that was rapidly building in her body. She was a very accommodating girl, but Luna was plain unjust right now in her eyes. She wouldn’t take it lying down.
That was when the petite Storm Valkyrie’s expression transformed. Gone was the disdain, replaced by a smug, condescending smirk dripping with victory.
And then, right in the next moment, that expression was gone. Luna tilted her head and let her long lashes flutter as she whispered in the sweetest, most innocent tone imaginable: "You’re right, Nyx. I’m not angry at all. You have the right to enjoy our boyfriend’s caressing in private, should none of us want to join in."
"!!" Nyx’s eyes snapped wide open with confusion and disbelief. "Then what gives?!! Explain yourself, or I’m really going to get angry!"
Luna giggled, her innocent expression deepening even further. What she said next, she said as if there was nothing wrong with it. As if she were as innocent as an angel. "I was just playing. It’s been a lot of fun to mess with you. Have a good time getting your fat ass destroyed by the Omni Cock. I’m out, I want to play some ranked games. Bye~"
With that, she withdrew her gloved hands, gave the toy a final taunting pat to leave it wedged deep inside Nyx’s cavern, and darted out of the room without another word.
Luna even used her electric agility to dip out of the room as quickly as possible, and for a good reason, because the door had barely clicked shut when it swung open, and in walked Kaiden. A towel was hanging around his hips with beads of water still dripping from his hair. It didn’t take a genius to figure out that he hurried with the shower, far too eager to return to Nyx.
Now, he was ready—ready both physically and mentally to give Nyx the perfect first time, the kind a precious girl like her deserved.
But instead of the scene he had envisioned, he froze in the doorway when he came face to face with reality. His eyes widened, locking onto the trembling girl before him. Nyx was still on all fours as he’d left her. But her hips were raised high with a thick dildo lodged deep inside her quivering butt.
The instant she felt his presence, Nyx’s head shot up. With wide, teary eyes, a whimper ripped free from her throat that trembled with shame. "Mmmhh!"
Kaiden stood there in silence for a long moment, staring, trying to piece together what had just unfolded.
But soon, it was obvious to him. Only one culprit came to mind. Aria would never dare cross this line. She might be a very possessive girl, but taking revenge against her friends like this wasn’t her style, not at all.
Kaiden nodded with a small sigh of relief. "Good. Because if she gave you real pain, I’d be thoroughly disappointed in her."
Then he shifted, moving closer to her rear until his presence loomed warmly over her trembling body. His lips brushed against her skin in the lightest of touches, kissing the curve of her butt. She exhaled softly as the humiliation mixed with the slowly rising heat.
"My lover’s been wounded in battle," he murmured against her skin. "So how about some healing kisses right where the injury took place? I read on the internet that it should help."
"What kind of shitty articles do you read?!" Nyx cried, but once she heard Kaiden only chuckle in response, she knew there was no escaping it. Her boyfriend was hungry for her ass, and he was going to take it.
The mere thought of that moistened her little sister like no other. Her breath hitched sharply as his hands cupped her hips, steadying her. She felt the dildo begin to move, slowly, carefully, as Kaiden pulled it free, inch by inch, while his lips pressed another trail of soft, reverent kisses across her flesh.
"Kai..." Her breathing grew ragged, and her body betrayed her flustered heart as she whispered his name under her breath without conscious thought. The mixture of shame, arousal, and his tender affection tangled together until she could barely think at all.
"Take me... Please... I’m begging... Only getting ravaged by your cock can wash my shame away..."
