Chapter 4

"Young master It's time for your monthly treatment" Annie said seductively as she walk slowly towards the bed where Eren leisurely sitting.
Eren put away the book that he's reading and divert his attention to the blond woman. He swear he'll never get used to this, this is the time of the month were Eren needs to have his release as his mother explains to him. Three years ago after his coming of age ceremony, his mother introduced Annie Leonheart to him as his private tutor. Aside from the normal tutor he has for academics, this one specializes the art of seduction and sexual pleasures. Unknown to him, Carla strictly instructed Annie to force Eren have his release every month by any means. Before Annie become Eren's private tutor, she's indeed a high class prostitute, Carla paid Annie a huge sum of money for her loyalty and services.

"Ms. Leonheart, I don't feel well can we just do this in some other time" Eren said hoping for a good answer.

"We can't young master we have to do this, please let me do my job my lord." Eren sighed in defeat and gave up his little argument that happens almost every session. He just let her have her way with him, he just made himself comfortable on his bed and waited for Annie's move.

"It seems that you're not really in the mood to do this young master… let me fix this for a moment" she said as she kissed him and through that she made him swallow something.

'That medicine again' Eren thought.

"Young master, before we move on to the next lesson, I must give you a test first, I want to see everything that you have learned so far." She whispered to his ear seductively. Eren tried to object but no words coming from his mouth, he knew that instant that the drug that Annie made him swallow is starting to kick in. He sits and let his back rested against the headboard he felt his body become hot, he tugged Annie gently and motioned her to sit on his lap, slowly she complied.
His left arm around her shoulders supporting her, his right hand between her legs, rubbing her core in a gently hypnotizing strokes. She moaned approvingly as she let her head fell backwards. "That's it young master you're doing it right ahh~" When her head touched the mattress Eren let her lay down completely as he move on top of her. He cupped both of her breast and sucked gently the one and then the other.

They were very plump and firm, Annies breasts. She looks like in her mid-twenties if his not mistaken.
He bit her nipples moving the breast roughly so as to feel their weight and then lightly as he slapped them back and forth, he knows Annie wants every session to be rough, and he now trying his best to be one. His manhood has been hard and almost painful to him after he swallowed the drug that Annie has given to him. He felt it pulsating, throbbing, somehow itchy and really hot, to the point of driving him almost insane.

The drug today was somehow different compared to the ones that Annie had made him drink in their past sessions.
This time was really strong. Panting as he keeps trying to regain his self control. He mounted her, parting her soft smooth creamy legs, rubbing her core harder than before, her breathing quickened, soft moans escaped her lips trying to encourage him to do more. She was testing him on how far can he go without her directing him what to do. He dug his middle finger in to her core making her red silk panties to dampen more. She arched her back wantonly as the second intruding finger was inserted. Eren didn't bother to undress her completely. He unbuttoned her white blouse with his free hand as he continue his ministrations.
He just tugged her lacy red bra lower so that her breast will pop out of the confines.

" My lord can you let me take them off completely because this is my favo- ahh~" Eren pinched her nipples as he mounted her and suddenly thrust his weeping rock hard manhood in to her core. He was holding her up as he did this, she arched her back higher as she could making her plump breast and hardened nipples pressed flatten to his chest. Her breast where squeezed together by that lazy undergarment that make them look bigger.
Eren didn't let her utter another word, he too k the opportunity of her open mouth to plunge his tongue and suck the life out of her. He explored her wet caverns as his hands pinched her breast sharply and thrust his hardened member in to her deeply at the same time in slow but sensual motion. In and out , in and out, repeatedly slowly catching up a quick pace he feels that his manhood was so hot and sensitive, desperately he thrust in to her to make the sensation go away, he needs to be deeper inside her, deeper as he could. Annie on the other hand keeps on moaning without restraint, she never felt this kind of sensation for a long time and indeed she taught him good.
Soon she finds her release and climaxed but Eren wasn't done yet because his body wasn't fully satisfied,
desperately looking for release he keeps thrusting in more frenzy manner, fast, deep short strokes arouses Annie again.
Moments later he finally groaned as he release his seed out of her.
Seeing his manhood was still hard and erect, Annie mounted on him and position herself on top of him this time. Initiating a daring move she straddled him and boldly put his hard rock member to her core. She placed her hands on his chest as she tweaked both of his nipples at the same time. Eren felt blood rushed through his veins going down to his manhood, Annie smirked as she felt the pulsating swollen member hardened more.
" Ms. Leonhart what are you doing?! Hngh~"
"Call me Annie, my dear master" Annie slowly moved her self up and down to Eren's rod.
"Ms. Leonhart hnggh~ ahh I-I c-can't hnghaa~" Eren can't control him self any longer and he needs another release.
He grabbed Annie's hips and slammed it hard to his manhood, he keeps on thrusting upwards with so much vigor occasionally forcing Annie to roll her hips by holding them, Annie was caught off guard in this sudden action and almost got herself off balance while straddling her student. Eren keeps frantically thrusting his hips in to her making her slammed and impaled to his manhood deeply, soon Annie reached her climax and so was Eren he took out his rod outside of her to finish his release. He's so tired that his sixteen year old body was barely awake. " You did good job for today young master, its way beyond expectation, as expected you're such a quick learner, please look forward to our next session, I'll teach you something new" Annie said as she started cleaning herself and dressing up like nothing happened.

After she finished dressing up she cover up Eren who's already sound asleep and silently walked out of the room.
"Armin, we're done, go clean the master now he's way too tired to do it himself again" Annie bluntly said as she walked confidently passed him. The strong smell of sex lingered around her as always. He can't help but to grimaced at her.
