You hear the sounds of someone masturbating beside you!

Squeeeeeeak. Squeeeeeeak. Squeeeeeeak. Squeeeeeeak. Squeeeeeeak. Squeeeeeeak...

Your eyes snap open at the softly repeated straining of the springs of a cot nearby. The pace is unmistakable. Someone is getting themselves off! A wicked grin crosses your face at the realization. "Unauthorized self pleasure" was strictly forbidden for any **** girls that had yet to be taken by Master. Your Mistress would surely punish your infracting sister initiate!

You squint into the darkness and identify the offending girl. Coraline!

Ehh... Ehh... Ehh...

Her ragged breathing chokes in the back of her throat. She attempts to hide her shame but like all of you initiate girls she has been denied sheets to sleep under. Only her sheer nighty permitted at night protects her body from the biting cold of the room. Her fingers are buried beneath the tiny strip of fabric covering her womanhood. They move with **** speed driving her closer.

A biting jealousy rises from within your stomach. She looks so hot. Her large D-cup breasts strain the delicate fabric encasing them. She fills out her nighty in a way your small breasts never could! The curves of her bubble butt peak from beneath her and tease your covetousness further. You would never admit it out loud but the voluptuousness of her body intimidated you. Throughout the early years of your training you would be **** to wear identical clothes as Coraline and the rest of your initiate sister slaves. You could only hope that your Master would your petite frame over her ample assets.

Still, you were far too calculating to not use this situation to your political advantage. You should rat her out to gain favor with your Mistress. Coraline would likely be punished or possibly even sold! That would eliminate a potential rival.

Of course... you're also horny.
