Push her further

"You better not stop!" you sternly whisper at her, before removing your hand from her mouth and kissing her deeply.

Your tongue dances with hers within her mouth. The locking of your lips mostly contain her hopeless sobbing. Both of your hands are now free to explore her breasts which are still pulled free from her nighty. Your fingers tickle at her wonderful D-cups.

One of her hands attempts to cover her **** melons.

Slap!

You swat her hand away and guide it back to her other hand still pounding away at her tender nether regions. Both of you carefully look around the room checking that the others have not awoken. Satisfied your eyes lock with her silently reestablishing your dominance. You _will _push her beyond her sensitivity...

Your hands return to her breasts gently teasing her peaks. Her arms flinch reflexively in but she dares not cover her exposed breasts. Coraline loses pace for a moment but catches herself and resumes her self clitoral flagellation.

Good.

Your hands resume their work gently rolling her nipples within your fingers. Her silent sobbing gives way to grunts in response to the new sensation. You alternate your frequency constantly surprising her, but she continuous as instructed.

Good. Time to help her over the top.

"Time to cum again, Fushidarana on'na"

You lock her in another kiss and capture both of her nipples roughly in each of your hands, and she instinctively freezes unsure of your next move. You give her trapped nipples a shake and are rewarded with her resuming her masturbation. Her nervous hiss escapes from between your locked lips.

Hssssssssssssssssss...

You begin gently pinching her sensitive buds harder between your fingers and are rewarded at an increased pitch in her moans. She kisses back more aggressively almost pleading for you to stop. You respond by increasing the pressure.

Errrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrgh!

You notice her fingers moving with a little more urgency within her panty. You can't help but smile letting her moans escape into the room briefly before shoving your tongue back into her mouth.

I know what she needs! You slowly pull her nipples skyward away from her chest. She is **** to arch her back off of the cot beneath her. There we go! Her slick fingers increase with urgency.

Aaaaaaarrrrrrrrrrrrrrrrrrrrrgh!

A growl stirs from deep within her as you pull her nipples further. Her back is as arched as much as she is capable. You hold her **** to endure in that position for several minutes knowing what the pain will do to her.

It happens again!

Mmmmrmmmmmmmmrmmmmmmmmrmmmmmmmmph!

She quakes in another intense orgasm. Her fingers pound her snatch furiously and you shove your tongue deeper as a reward. She kisses you back desperately. You are not sure if it is in thanks or pleading for your permission to stop masturbating. You leave her guessing for a few moments waiting for her fingers to stop.

Squish...Squish...Squish...Squish...Squish...Squish.....Squish.......Squish.............Squish.............Squish...

You release her nipples and she collapses exhausted back onto the cot beneath her with a painful yelp. Her hands immediately cradle her abused tits. She winces as she massages the blood back into her nipples. You smile down at her as you watch her nipples slowly resume to their original shape.

"Why did you do that, Yoshino?!" She whines softly up at you as she stuffs her glorious tits back into her nighty. She massages them further through the delicate silk fabric wincing but not stopping.

"Because I know you're a little pain slut like me."

"I am not!" she protests.

"Bull shit! You and I have been cumming together for weeks in training. I knew I could get you to cum... and you did! Twice!" you chuckle cruelly.

"Fine!" she says still rubbing her tits protectively, "But you didn't need to enjoy it so much!"

You giggle again and slink back to your cot. You lay down watching Coraline continue to rub her sore tits. She will be feeling that still in the morning! Your eyes get heavy and you repeat a silent prayer to Amaterasu for the other girls not waking up and descend into an exhausted slumber.
