'''Coitu Vocationis: The mating call spell'''

'''Coitu Vocationis is an old utility charm that hunters extensively used to track down and kill magical creatures back when hunting most creatures was completely legal. The Mating Call spell simulates the mating call of a particular magical creature and thus could attract significant targets during mating season.'''

'''The mating season of each magical creature differs and thus the same spell could be used all year round but for different animals. The spell works by recognizing the sound an animal makes before it can bounce that same sound from a solid object. Also of note, is that this is a spell that is derived from the spell Vocationis that can not only recreate the mating sounds but every sound an animal makes. The reason this derived spell was made was the ineffective need for a spell that could...'''

'''Vocationis: The Echo spell'''

'''An auditory spell that can recreate any sound that it hears, a commonly used spell used to supplement most illusions giving them a more realistic look. The spell works by recognizing a sound that is close to the wand before it can bounce that same sound from a solid object when the spell is cast. The maximum duration that your magic will remember a sound would be 3 months and after that, you would have to rerecord that sound.'''

'''The wand movements to the spell is an inverted 'L' followed by a drawn-out backward spiral. The second part of the wand movement is the recording section where the spell would recognize the sound vibrations that it could comprehend. The incantation of the Echo spell is 'Vo-Caat-ioonis'.'''

Rigel leaned back in his chair after he finished reading, the 3-month timeline was a little strict but something he could deal with. The first time the chamber opens should be around Halloween if the diary is in the hands of a first year, maybe longer if the diary is in the hands of a senior student. 

'Halloween is in less than 2 months so I should be fine, now all I have to do is talk to Hagrid and wait for a Rooster to crow, at around 4-5 am in the morning...' Rigel thought as he stood up. At least he had a somewhat working plan, he looked at the clock and noticed that it was almost time for dinner. Not wanting to piss off Daphne more he closed the book and walked out of his room.

'Now I just need to learn this spell and test how effective it is...'

"Yesss~ Merlin yes, fuck me haarderrrr~" Evelyn moaned. Rigel looked in fascination as her tits bounced up and down with every thrust. Her D-cup breasts were surprisingly perky even though she was lying on her back, her hands sprawled to the side as she gripped the bedsheets to get a better grip.

Not that she needed to as his left hand circled her legs that were going over his shoulders. He kept her in place as he bucked his hips forward and with each thrust Evelyn had a mini orgasm, the pleasure had somewhat melted her brain as she simply threw her head back and moaned.

"Yeaaaa~ Fuck~ Yess~ Fuck~" Evelyn moaned not realizing that she was simply repeating the same sentence over and over again. Not that it was her fault, Rigel had simply found a rather creative use of the spell that he had learned earlier today.

"Yeaaaa~ Fuck~ Yess~ Fuck~" 

"Yeaaaa~ Fuck~ Yess~ Fuck~" 

"Yeaaaa~ Fuck~ Yess~ Fuck~" 

"Yeaaaa~ Fuck~ Yess~ Fuck~" 

From the four different objects mounted on the walls of his room, the same moans of Evelyn being hammered repeated creating a lewd atmosphere. Evelyn had unknowingly been repeating her own words that were echoed by the walls. The spell was not that easy to use as the walls of his room simply rejected the spell. It didn't take long for Rigel to figure out that the runes of the wards that were etched on the wall were somehow interfering with the magic.

So next he attempted the same spell on his wardrobe and table and they worked just fine. Along with some new reps on the spell it also allowed him to further humiliate Evelyn a bit.

"Can you hear yourself? Begging to be fucked?" Rigel asked as he leaned down and grabbed Evelyn's head by her hair, her half-lidded eyes focused on him slowly as she continued moaning. Her entire face relaxed and winced with pleasure with every thrust as Rigel continued to dominate her.

His own orgasm continued to build up as he watched how powerless the 5th-year prefect was under him. He let go of her hair as he probed her lips with his thumb, her mouth opened without any resistance and she simply started sucking on his thumb. For a moment Rigel regretted not picking the Naruto world, even though he knew that he had selected the right choice, the fact that there was a jutsu like the shadow clone that would allow him to spitroast a girl was a definite loss.

'I don't think that something like that is possible with magic, unless I'm going to make a Horcrux and resurrect the broken soul...' Rigel dismissed the ridiculous idea and focused on the mini-bimbo under him. Her entire face was slack and for a moment Rigel regretted breaking her this soon. The combined effect of 2.5 times the pleasure was too much it seemed, as within 3 days of continuous fucking Evelyn's Mind break requirements were completed and he got an additional reward. 

'Though I was not expecting these results, at least it frees up a slot so I can focus on another girl to break. I wonder how long it would take to break someone like Narcissa.' Rigel thought, the thought of the blond with tits bigger than her face pushing him over the edge as he slammed his dick in her and blasted his load against her womb.

'Requirement Analysis...' Rigel thought as he dismissed the Pleasure lock on Evelyn as the black-haired bimbo started convulsing slightly.

'Still no idea huh, how do I unlock these conditions?'
