The sister's mind flooded with fear and regret, realizing herself to be wildly outmatched and outgunned - inexperienced and already losing control of her body, which began to, against wishes, hump at the instructor's expertly used fingers. Ms. Sheppard, in full control, gently lowered herself and her opponent to the shower floor until both sat Indian-style, then in a single maneuver, wrapped her luscious legs around the body, and then in between the legs of her rival, only to pull both back firmly, to allow complete, and unfettered access to the sister's vulnerable pussy.
Free to do as she pleased, and unconcerned about the possibility of the sister's escape, Ms. Sheppard lowered her second hand, and began with both to simultaneously thrust her fingers in and out of quivering pussy lips, whilst also fully stimulating the clit of her opponent. The devastatingly effective attack seemed like it took hours to Guiying, but in reality, took all of 23 seconds, before she who came with such fire a tumult came again, this time exhausted and beaten - humiliated and humbled. The young woman then tried to stand, as tears ran down her shame-etched face, but found that she was not allowed - not free to move, still secured tightly in the teacher's embrace.
Ms. Sheppard: "Shhh, stay with mommy." The teacher whispered, as she without warning, launched into another bout of impassioned fingering, and touch-perfect clit-rubbing, causing Guiying to begin to buck and struggle, the feeling of pleasure far too overwhelming to tolerate, and yet..it continued unabated. The sister screamed, not for help, but for mercy - not in words, but in shrill, panicked cries. Ms. Sheppard did not relent however - finding no mercy in her heart for she who had been so insulting when she arrived earlier in the day. And so she forced to her cum, over and over again, until finally the screams stopped, and Guiying collapsed from exhaustion, falling back further into her new master's arms, until it was only the latter that kept her upright. When Guiying finally felt her body's release, and the warm shower floor taking all of her, she began to sob uncontrollably.
Tears of abject regret she shed, until they were interrupted, and replaced with those of pain, elicited by her limp body being drug up from the wet floor, and after a short, forced weak-kneed walk, tossed unceremoniously onto Ms. Sheppard's bed.
Ms. Sheppard: "This is where this was supposed to end, SLAVE, and so this is where it will end."
Ms. Sheppard: "NOooOo, please..." She muttered weakly, as her blonde tormentor climbed atop the bed, and with rough, violent motions, locked each of them into a tight, clit-on-clit scissor.
Ms. Sheppard then began to shout as she thrust her hips, and lips, into Guiying's.
Ms. Sheppard: "Fight back! Fuck me, slave! FUCK ME!" The commands come with slaps, each of which land on every part of the sister's body that can be reached. They hurt from the first, and grew with intensity from there, the pain they inflicted forced Guiying to try and take her shaking hands from trying and hide her endless torrent of tears, and instead to try and block those places on her body she felt were most exposed. Despite her pitiful state, Ms. Sheppard continued to strike, and thrust, until finally, pathetically, the dark-haired girl managed to muster a few, pain and fatigue-weakened thrusts of her own, the last of which causes her to once again orgasm at the touch of her master.
The teacher, then satisfied by the showing, meager as it may have been, continued to hump, until finally she and once again her opponent came, for the first time in unison. From that release, the blonde made not a sound, instead focusing each remaining motion and thought on pumping every last drop of cum from her now thoroughly destroyed opponent.
All went dark for Guiying, as she passed into a ravaged unconsciousness, until finally her eyes opened, and she found the smiling face, and drying body of Ms. Sheppard, who sat upon her in a straddle, her own unconquered pussy lips sealed around the still-erect nipple of her new slave.
Ms. Sheppard: "Wake up, slave, we must prepare for your brother." The sentence perfectly encapsulates the nightmare world in which a sister, who set out to protect her family's honor and little brother, now finds herself in.
