Ruby: WHAT!?!?!?!

Yang: Please!!!!!!! Please watch me and Blake have sex!!!! Blake has a kink and wants you to look!

Ruby was surprised and speechless. Looking at her sister begging on her knees made her think of how it might be hot.

Ruby: So... Just watch?

Yangs eyes widened as she gave a huge hug to Ruby while giving her non stop "thank you".

[Later that day]

Yang: God why is my cock harder than usual~?

Blake: Seems like you also enjoy being watched. Especially by your cute younger sister~

Blake continued to suck on Yang's throbbing cock while Ruby sat in the corner. Ruby was mesmerized by how Blake's tongue glided all around her big sister's cock. Blake's eyes met Ruby's and she began to face fuck herself on Yang's cock. Ruby's heart began to beat faster as she heard those sloppy throat noises. Ruby bit her lower lip as she felt her pussy start to get wet. Ruby couldn't hold back and slid her hand down her panties. Blake smirked and pulled out Yangs cock from her throat. Yang's saliva covered cock pulsed hard trembled as it wanted more pleasure. Blake gave the tip of Yang's cock a kiss and stood up to begin to slowly insert it inside her already dripping pussy. Yang quivered as Blake slid Yang's throbbing inside all the way to the base. Yang usually wore a condom but Blake decided that Yang was going to breed her in front of younger sister that day. Ruby couldn't look away as the room filled with wet slapping noises and moans from the two women going at it. Yang suddenly wrapped her arms around Blake and began to thrust upwards and made her quivering nuts slap against Blake. Yang groaned loudly and began to twitch wildly into her girlfriend's pussy while emptying everything she had saved up. Blake continued to give small bounces and made sure Yang left every drop inside. As Yang's cock flopped out it flung a drop of cum at Ruby's face. Ruby gulped as she gave it a taste and savored it.

Blake: Same time next week ladies~?
