HP: In The Magical World As Draco Malfoy

It was quite late when I returned to the manor. I knew the best thing to do would be to return my room and continue my research, less change I made, the better. 

However, watching Hermione's mom in the shower made me quite horny, making me more aggressive about my plan.

I walked towards the room Narcissa was using as her bedroom after a brief pause to change into sleepwear. 

I had no fear of meeting with Lucius in her room, because they had separate rooms according to Draco's memories. 

I stood in front of the door, trying to put a depressed expression on my face, and knocked the door.

"Who is it?" Narcissa said, startled a bit.

"It's me, mom," I answered, trying to make myself sound depressed.

A few seconds later, the door opened, revealing Narcissa as she tried to wrap a robe around her. "Did something happen?" she asked in a panicked voice.

"Can I come in," I said, keeping my gaze low.

"Of course, my dragon," she said and pulled back, letting me join her in her room. "What happened?" she said after I entered the room.

"I had trouble sleeping," I murmured, trying to sound as pathetic as possible, hoping that would hide my enthusiasm. "Dumbledore's face is appearing whenever I close my eyes."

"Oh my poor son," she said and hugged me.

I turned slightly to hide my boner, as the sensations from her silk-wrapped body didn't help my efforts to keep things under control, her robe and nightie doing little to hide her body from touch as my hands slowly roamed her back. 

I was so tempted to push her down and enjoy her body, but held myself back. I didn't want to ruin my plan with an untimely indulgence. 

"May I stay with you tonight?" I asked.

She pulled out of the hug and looked at me with shock. I could almost see the thoughts flying behind her startled expression, trying to understand my sudden change of behaviour, but soon, her expression softened, doubtlessly blaming the stress Draco was under for the situation. 

"Of course you can, Draco," she said, trying to smile in a carefree way, though I could easily see the worry peeking under her fake expression. 

Someone nicer than me would be feeling guilty about her motherly instincts to attain such an achievement, but unfortunately for her, I wasn't a nice person.

Neither of us spoke as I slid under the covers while she turned off the lights. I listened to her removing her robe, then she joined me under the covers. 

I wasted no time before wrapping my arms around her torso and pulling her closer. 

She stiffened, but said nothing, moving a bit to make sure she was comfortable. A couple minutes later, I was in a fake sleep. 

Narcissa lay motionless, but it was clear that she was still awake.

Of course, her relative calmness wasn't to last. I had brought one of the lust potions with me, one applied through skin absorption. 

I brought my hand into my pocket, putting a decent amount of it to my hand, significantly more than the recommended amount. 

I put my hand over her naked leg, glad that this particular potion was barely noticeable during the application process. 

I slowly dragged my hand on her skin, once again surprised how smooth it felt.

She squirmed a little under my touch, as it landed on her thighs, but she didn't act out after realizing my hand wasn't climbing upwards. 

I poured some more potion on my hand and applied just in case. After all, I was planning to make her break a really important taboo. 

Of course, there was a side effect of applying the potion with my bare hands, a generous portion of it seeped into my own bloodstream, making my cock to flare into life. 

Thankfully, Narcissa's body wasn't close enough to my waist to notice. 

I moved my hand back to her torso and wrapped it around her waist, loose enough to not to make her uncomfortable, but tight enough to make sure she won't be able to slip out of the bed when the arousal finally hit.

First effects appeared after fifteen minutes, fifteen long, agonizing minute, with nothing to do other than listening to my excited heartbeat. 

First, she shifted her position, hoping that it would fix her issues. Then, her lethargy evaporated, and she started to squirm. 

I let my hands settle on her midriff, but otherwise stood completely still. 

Soon, her squirms turned into writhings, and she tried to stand up from the bed, but I made sure to act the part of a clingy sleeper, keeping my arms firmly around her waist. 

Unable to stand up, she shook my shoulder a few times, but I continued to play while sleeping.

It didn't take long for her to give up, which surprised me. I was expecting for her to struggle harder. 

For a moment, I was afraid that she had more willpower than had previously assumed, and the night was going to be a dud. 

But then, she shifted between my arms and turned her back to me. More importantly, I noticed her hand sneaking down under her robes. 

Knowing she cannot see my face, I let a smile pop on my face as I listened to her quickened breaths. 

I waited a couple of minutes, enjoying her frantic breathing, getting more out of control every second.

Then, without a warning, I pulled her close, my erection resting between her tight buttocks. Her whole body froze for a second, then she tried to pull away, only to be prevented by my grip once more. 

"Please wake up, son," she asked even as she shook my shoulder, but I continued to act like I was asleep. 

This time, keeping the sleeping act was even more difficult, considering the pleasure was spreading to my body with each movement. 

I was happy when she turned her back to me once more, but it didn't compare to when her hand sneaked under her robe once more, rubbing herself rhythmically.
