"I am yours mistress...I am yours to use as you see fit.." Marianna whimpered as she was being toyed with so well and groaned being told what to do as she nodded and left the shower heading to the nearby draw and bringing out the long road of soap like a dildo strap on as she blushes handing it to Vera softly,

"H-here mistress," She whispered as Vera would put it on as Marianna turned around and leaned forward spreading her legs a little as she flinches feeling the dildo rubb between her thighs teasing her before Vera went for a big thrust as she moaned as her inside where stretched out by the soap dildo as her hips twitched against the intruder as she whimpered in pleasure.

"Mmm... A nice tight fit," she purred, bucking her hips upwards to force another inch in. With the water and sexual juices, the soap glided easily along the student's inner walls. Vera handled her new pet roughly, pressing hard up against the woman's back so each thrust would force Marianna's hardened nipples to drag up and down the smooth tile wall. She picked this position to show just how much power she had over the woman. The hypnotist would be able to do nothing but rub against the wall and Vera's body while those hands paw weakly against the unfeeling surface of the wall.

"I don't hear you begging," she whispered into her ear before nibbling on it lightly with her teeth. Her hips pulled back before thrusting deeper into the woman. She kept thrusting harder and faster, harder and faster. The thick knob at the end pounded away at the student's cervix, filling her shivering folds with the scented soap. The Head Girl would ensure this would be a night she would not forget.

"Oh god...please mistress! Harder! Faster! I'm just your toy play with me please!" Marianna cried out as her breasts where rubbed against the shower wall as she weakly pressed her hands on the wall panting deeply as the pleasure coursed through her causing her loins to wetten faster as her insides where being scented by the soap as she gulped and began losing her leg strenght and falling to her knees slowly.

The woman was rewarded with pleasure both mentally and physically as Vera fucked her and she begged for more. It was a relentless cycle. The poor girl was already weakening, her strength and stamina ebbing away as the Head Girl just kept going and going. Both juices and suds dribbled out around the soapy rod. The silver haired woman grunted softly with exertion, pushing her hips harder as the blonde woman begged. Being pressed up against the wall gave the weakening woman some support as each thrust forced her body back upwards some. Vera was not about to let this one fall away from her until she has finished fucking her into release.

"Oh my...please more! More! I'm so close! So close!" Marianna's only words she could say as she was getting wetter and wetter closing in on his climax as she gulped as her legs twitched more as she was moved up more as the thrustings continued as she moaned louder.

"OH god...i'm...I'm cumming!" She screamed out as her pussy clenched around the soap dildo and cummed a huge gush of fluids out of her as she pants almost collasping.

The sight was nothing short of magnificent. Marianna spasmed violently against the wall as waves of pleasure wracked her entire being. Vera kept thrusting, prolonging the bliss as long as possible. She even pulled the woman off the wall and began playing with the slave's swollen clit, pinching and stroking it rapidly as her hips continue to buck upwards.

Only when her pet could take no more did Vera finally stop. She removed the strap on as she allowed the woman to fall to the floor. "Here," she offered the soapy rod, now smaller and different shape due to all the thrusting in a tight passage, "Clean yourself off. When you finish, you may wash my back." The rest of the shower was uneventful though sensual as the Head Girl occasionally allowed her hands to wander to her pet's body to assist in cleaning her. She pulled her long silver hair to the side to allow the woman to scrub her back.

When finished, she dried off along with Marianna and allowed her hair to be brushed and combed by the other woman. "You have done very well my pet. Do not forget the lessons you have learned here. When I call you again, I expect you to arrive here with no delay. Also, you are to tell no one about coming here and seeing me. If you tell someone, I will not call you to serve me again. Do you understand me, my pet?" Vera would have loved to have her pet stay the night but unfortunately the records showed that she had a roommate. There was no need to attract more attention to herself than needed. She now had a reliable pet to use and experiment on in the future.

Marianna panted deeply before she quickly cleaned herself with the soap and the water washing away any of her orgasm off of her before she stood up and slowly began washing the back of Vera softly enjoying the reward as she only washes her back with the items she had and the many soaps and other things, being careful not to do anything wrong.

Afterwards she steps out with Vera as the pair dried off, as she began combing and brushing the hair of Vera gently being careful with her mistresses hair.

"Yes Mistress I understand, I shall remember my lessons well and return when you call for me post haste...I won't say a word about what has happened..I promise you," Marianna said softly as she keeps brushing the hair calmly until it was done, the pair knowing she had to get dressed and leave.
