Chapter 12 (R18)

I leave her to her payback as I continue to the great hall for some food, hearing some commotion behind me as Diana takes her time to send a message to her fellow Slytherins.

​

Diana only had to make a few more examples before Slytherin house as a whole decided to just leave her be, ignoring her entirely as long as she didn't bring attention to the house.

It only took a few weeks in regards to her accepting how things were between the two of us, the 'perks' I shared with her making her will crumble fast, and before long she was following behind me in the moments I decided to give her some personal attention.

'Glrk. Glrk. Glrk.' The noise of her current actions sounding out into the room.

It was only a few days before Halloween and a free period before dinner, when I had grabbed Diana and brought her to one of the rooms we frequently used.

After locking the door behind us I had preceded to lean against the edge of a desk as she dropped to her knees, fumbling open my pants to fish out my cock, as her robe and shirt was opened to show her perky breasts, her nipples rock hard in arousal.

"You've gotten pretty good at that." I compliment her, stroking her hair as her head bobbed back and forth, her eyes rolling in her sockets as she used her mouth to pleasure me. Her hands were under her skirt, playing with herself as all her attention was on the two of us.

It didn't take her long before she was shuddering, her mouth stopping around my base as the orgasm hit her hard, though after much practice she pushed through enough to pull back and take some deep breaths before continuing in her actions, trying to bring me to completion.

Before she could though, I thought I would try something different this time.

Drawing a confused note from her as I pulled her head back and off my cock, she squeaked in surprise when I lifted her up and laid her down on her back over the desk I was just siting against, her heaving chest bare as her robes lay open to her sides.

The look on her face showed her understanding of what was about to happen as she turned her head bashfully, unable to look at me as I slowly drew her soaked panties down her legs before throwing them aside.

"I believe it is time for us to go a bit further than usual don't you think?" I ask her as I bunch her skirt up, revealing her puffy lips dripping with arousal.

Unable to voice an answer, she merely widens her legs and shakily nods, as she physically shows her compliance.

Laying my length on top of her stomach, her gaze is drawn down to see just how deep she is about to take me, as her hands raise to lightly stroke me.

"But first we'll need to do something about my first present being in the way." Reaching down to her covered asshole, her shock is voiced with a confused moan as I grab the end of the plug, slowly pulling it out.

"W-wait, what?" She stutters as she realizes I have no plans to take her purity and instead have my eyes set on a lower prize. "But a-aren't you going to t-take my.." Her words trail off ass I pull back to slowly rub my tip against her now gaping rosebud.

"You haven't earned that right yet, my pet." I barely explain before giving a hard thrust, hilting to the base as I enter her ass in one complete motion.

"Nngg!" She grunts as her eyes cross at the sudden fullness, her body wracked with an instant orgasm as her arms fail her and drop to the side, and her head falls back.

Not giving her any time to adjust, I proceed to grab her hips and go all out, causing her breasts to violently shake back and forth with my motions, the grunts and moans constant as she continues to shake in pleasure.

After a minute of her just laying there however, I pull a hand up and slap her breasts. "Look at me." I command as my voice is slightly strained from the effort of my movements.

Getting no response though, I give a few more slaps and a few pinches to her nipples. "I said, look at me." Finally getting a response her head jerks up slowly as her eyes try to focus on me, her tongue sticking out as drool drips out her lips.

"Nnggg?!" She isn't even able to voice words as she goes through orgasm after orgasm, her mind melting from the unusual pleasure.

"That's better." I praise her. "Keep looking at me, let me see your face as you cum."

She tries her best to follow my orders, though occasionally I need to give her tits a slap or pinch when she falters and her head falls back down. When almost 10 minutes pass of continuous movement, my motions increase in pace as my breath picks up. "Where do you think I should plant my seed my pet?" I grunt out in question, wondering how she will respond.

It takes her a bit for the question to penetrate her mind but soon she forces a scream out. "I-inn-side meee! Inside me, M-masterr!"

"Very well." I grunt as after a few more thrusts I push as hard as I can, holding my dick as far in her as possible as I release my load deep within her bowels.

The feeling of my cum inside her causes her to scream out, her arms twitching as she loses all control of herself, her head falling back for good and her tongue sticking out as her head lists to the side.

She continues to twitch and jerk in the after effects of her last orgasm, moans and grunts sounding out with every breath.

It takes her a few minutes for consciousness to return as her head slowly turns to me, her eyes lidded as she continues to pant.

"D-did I do g-good?" She whispers.

Slowly rubbing her stomach and upper mound, I get control of my own breathing and give her a nod. "Yes my pet, you did."

Her head lags back at my words as she seems about to doze off, though her head snaps back up when I pull out only to quickly thrust back in again.

At her questioning look I merely chuckle. "Did you really think we were done?"

Any further questions die on her lips as I return to my previous pace, moans and grunts once again coming to her lips.

As I sit at the Ravenclaw table, the hall decked out in decorations for the other schools arrival, I take a moment to glance at Diana at the Slytherin table, as she frequently shifts in her seat, dealing with the consequences of our recent meetings. From time to time I see her subtly reach up to touch her throat, feeling at the hidden collar I had given her the previous night.
