[Belle's pov]
Belle is feeling weird lately and the reason of it is of course her brother
She has always loved her brother and cared for him but in past days she feeling something that she hasn't even imagined she would feel it in the first place and cause of that feeling is something happened days ago in Alex's room
_
Belle is talking comfortably with Alex in his room when
knock, knock!
Belle glanced at the door
Alex stood from the chair and walked to the door. Belle saw Olivia when Alex opened the door. But she also noticed something weird. when Alex saw Olivia he greeted her
"Good morning, ma'a-Olivia"
Belle looked at them with a confused face. Alex looked at Belle quickly and averted his eye when he saw her looking at him
'What ? Is he trying to say ma'am but quickly changed it to Olivia ? They were having a good relationship past days but did something happened after the awakening ceremony. Liv also acting weird lately. She always had a mischevious smile whenever i see her past days. Did auntie Jen mischeviousness also currupted her mind ?'
Belle lost in thought when she suddenly heard Olivia's voice
"Good morning, sis"
Belle snapped from her thought. She looked at Olivia standing in front of her
"Ah.. Yeah, Good morning, Liv. How is your day ?"
Olivia smilingly looked at her and answered
"I was bored at home so i came over for some 'fun' with Alex"
Belle becomes confused when she heard the word 'fun' for some time and gazed at Alex but he avoided her gaze by turning his head to a side. She then realized the meaning of 'fun'
'Dammit!, how can i be that clueless about that types of things but...'
She glanced at both of them
'Aren't they recently become adult ? Kids these days.. Sigh...'
She stood up from the bed. She then gazed at both of them with a grin
"Well.., i should be get going. I don't want to disturb when you two having some 'fun'~ "
Belle started to walk at the door when Olivia grabbed her hand. Belle looked at Olivia and saw her mischevious expression
"It's alright sis, i want you to stay here and join us for some 'fun'. Of course, Alex won't mind. Would you Alex~ ?"
Hearing Olivia's word Belle's eyes widened
'What!? W-why i'm included in this ?'
Belle looked at Alex. He also has a shocked expression. He thought for some time and gulped. Then he looked at Belle briefly and averted his eyes
"N-no, i should go. I don't this this is a good idea"
"What are you talking about sis ? You will just watch the 'fun'. Don't tell me you were thinking something lewd~ ?"
Belle face turned crimsone as she averted her eyes and stuttered
"N-no!, i wasn't"
Olivia giggled seeing this
"Alright~, why don't you sit on the chair and enjoy the performance"
Belle tries to calm down herself and thought
'Watching...., isn't watching also wrong ? Especially i'm their sister. No, i should go.. But... Why i am feeling a little hot thinking about the 'fun' ? Something must have wrong with me'
Belle snapped from her thought and glanced at both of them
'Gasp'
Alex is naked below and his lower body is completely exposed while Olivia is sitting on the bed closer to him
'I..., i haven't seen it in years but..., is that the size of the average 18 years ? It seems a little.... Uh, tiny ? ..., What!, why i'm thinking about the size of my brother's things ?'
Belle shook her head and tries to walk out of the room but she froze when she heard Olivia's voice
"Get on all four and lower your upper body to the ground Alex"
Belle turned toward them
Alex is fidgating and glancing at her many times. Then he obeyed Olivia's command and got on four and lowered his upper body to the ground like a dog. His ass sticking upward toward Olivia. His dick also become hard. He lowered his head more into the ground due to embrassment
Belle eyes become wide and she froze in the place
'What!?, what's happening..?'
Belle turned to Olivia
Olivia noticed her gaze and gave her a grin
She then mouthed Belle
"It will be exciting"
Then Olivia turned to face Alex. She asked Alex
"Are you excited about the fact that your sister also present here to withness your show"
"N-no"
"Hee.., then why is your.."
She raised her hand and
Smack!
Slapped on his right buttock hard
"Argh!"
Olivia spoke again
"Dicklet is hard!"
Alex buttock become red as his body throbbed in pain and his dick twitched upward
Belle is frozen still on the floor. Her mind can't form any thought as her eyes glued to Alex's throbbing body. Olivia gave a side glance at Belle and smiled. Then she asked Alex again
"Tell me the truth Alex,were you excited that your sister is watching you while you were being humiliated ?"
Alex didn't answer and kept quiet
Olivia raised her hand and
Smack!
Slapped his left buttock hard
"Argh!"
Alex screamed in pain again. His dick also twitched and started to leak precum. He answered
"Y-yes"
Smack!
"Argh!"
"Again!, sis Belle can't hear you~"
Alex stuttered in pain
"Y-yes, I-i'm aroused when my sister watching me being humiliated"
"Good boy~"
Smack!!
"Ah!"
"Oh~, did you moan, Alex~ ?"
Alex didn't answer and kept quiet
Olivia glanced at Alex's buttocks which has turned red due to being slapped and her eyes curled a little. She raised her hand and
Smack, smack, smack, smack,...., smack!
Continously slapped both of his buttock
"Ah!, ugh!, uh!, ah!,....., ah!"
Drools and moans also continue to leak from Alex's mouth as his body shakes due to being slapped. His dick twitched more and more precum started to leak from it
After the continous slapping Olivia stopped her hand and panted a little. Alex also panted on the floor while positioned like a dog
Olivia recovered after some time and looked at Alex. Then she stood from the bed and lowered to her knee in front of Alex's face and whispered on his ears
Alex's dick continue to twitch hearing her whisper and his face turned redder. He also glanced at Belle direction a little. He withdraw his gaze in shame and lowered his head. Seeing this Olivia grinned and raised her upper body. She again sat on the bed while facing Alex's ass
"Alright~ Alex, get ready~"
She raised her hand again and
Slap, slap, slap, slap,...
Slapped His butt again
"Ah!, uhh!, ugh!, ah!,....."
Alex started to moan again and his dick also started to twitch more vigorously
Olivia continue to slap his buttock and at last she raised her hand high and
Smack!!!
Slapped his right buttock hard
"Ah!!"
Alex moaned out loud and cummed on the floor
Splurt, splurt, splurt, splurt!
After splurting on the floor he panted hard on the ground. Olivia didn't wait for Alex to recover his breath and spoke
"Where is your gratitude Alex~"
Alex shuddered and spoke while panting
"T-thank you,hah...M-ma'am for spanking huu... me hard"
Olivia smiled and patted his head. Then she glanced at Belle and spoke in a mischevious tone
"Did you like our show~ ?, sis~"
Belle snapped from her reverie and turned her head to Olivia
'What ? What did i whitness ? Is this the type of relationship they were having ? This is so... Vulgar'
She then finally realized her breathing is irregular and she felt wet under her jeans
'Why is my breath is irregular and why i'm... aroused ? Something most have terribly wrong with me. This is wrong. I should not feel like this seeing my brother being humiliated but...'
She glanced at Alex. He is still panting while posing like a dog. The floor under him is in mess as his cum continue to drip from his dick
'Why it is so arousing!?'
Belle screamed on her head. The she started to calm down and walked to Olivia. She grabbed her hand softly and walked toward the door. Olivia didn't protest and walked with her. After walking out of the door she gave a last glance to Alex
He is trying to wear his shorts but whenever it touch his swollen red buttock he stop his hand with a pained look. Belle glanced at his butt and gulped. Then she turned her head closed the door
