{[Last Time in Tainted Desire]}
I was lucky to be able to wake up before Narcissa, my hand still on her tits, my morning wood trying to push her naked ass cheeks. For a moment, I considered pulling my hand back and fixing her clothes before she woke up, but I didn't put that plan to the action, mainly because she was more than willing to sleep with my hand there. I wanted to see her reaction after waking up, especially after I dabbed some lust cream on her thighs once more. I reached the bottle and poured a generous amount to my hand, then dragged my hand on her thighs, careful not to wake her up, then continued to play possum.

{[Now]}

With the addition of the potion, it didn't take long for her to stir up once again. I held my breath, curious what she would do. Even with the last night's events, her reaction managed to surprise me. When her hand reached the one that was holding her breast, I was expecting her to try to pry my fingers away, not putting pressure to sank my fingers into her flesh. She started to grind her hips to my cock once more, separated just by my sleepwear, moans starting to escape her mouth almost instantly. I was so tempted to push her down and fuck her mercilessly, but I held back. I could easily see that her courage was artificially raised by her lust, and I didn't want to test just how good it would stand against my active involvement. So, I held myself back…
For now…
*******
It had been one week since I had first entered Narcissa's bed. During the week, I did nothing other than studying magic during the daytime, and slowly teasing Narcissa during the nighttime. I had yet to go farther than the second night, when I molested her naked breasts. But during the week, I gradually reduced the amount of lust perfume and cream I was using, so much that, yesterday, I had used nothing but a dab of perfume, and she had rubbed herself raw while grinding to my sleeping body. Lucius being sent away on a mission was a godsend gift, robbing Narcissa of only convenient outlet she had.
This time I didn't even bother to knock the door, and pushed it open after an unlocking charm, only to see Narcissa trying to push her negligee down, her breathing shallow, her panties absent. I could see her fingers still glistening with her juices. "What did I say about entering without knocking, Draco?" she said, but her tone was far from angry, filled with excitement instead, flared by the thought of being caught.
"Sorry, mom. I won't do it again," I said, both of us aware it would happen once again. We talked a bit casually, while she was doing her best to keep her short negligee down to hide the absence of her panties. A useless gesture, considering the clothes she wore tonight was even thinner than usual, making the absence of her underwear clear very distinct. I could easily see the shape and color of her spectacular breasts, their small pink areolas peeking through the dark fabric of her clothes. She looked like she intended to be under covers when I arrived, but the miscalculation didn't seem to bother her. She only had a gentle blush covering her face while she tried to act unaware of her revealing state. "So, how do you feel?"
"I feel fine, why do you ask?"
"You look a bit tense. How about a massage. I don't want you to have an uncomfortable sleep."
For a moment, Narcissa looked indecisive, so I walked towards her, careful not to let my gaze wonder over her body. "Sure, why not," she murmured, and laid on the bed. I smiled. I wasn't expecting her to agree that quickly, not that I had any complaints about her quick compliance. I started with her neck, gently rubbing her smooth skin. Of course, she wasn't aware that my fingers were covered with a thin film of lust cream.
She started purring softly before I even reached her shoulders. I hooked my finger to the straps of her negligee, and slid them down. She didn't notice, at least not until I slid her negligee down enough to most of her back. "Son?" she spoke in a slightly alarmed tone.
"It's hard to do it efficiently through the fabric," I said, pressing my hands hard on her back. A loud moan escaped her mouth, but she didn't say anything else as I continued to caress her back, not even when my fingers caressed the edge of her breasts. When I finally reached her bottom, I skipped it, shifting down to her feet instead. A silent, disappointed hiss left her mouth left her mouth as I skipped her ass.
I focused on her feet, raising them a bit even as my fingers danced over them. I started climbing, first to her calves, then to her thighs, pushing her negligee up on every beat. Soon, I managed to push her negligee enough to reveal the unobstructed view of her pussy, sopping wet with arousal, without her realizing. I lingered over her thighs for a long while, rubbing generous portions from the lust cream. Soon, she stopped bothering to keep her voice low, every moan ringing between the walls. It was finally time to move to the next step.
I didn't ask for permission before moving my hands to her ass, sinking my fingers deep without a warning. A shocked moan escaped her mouth, erotic enough to make my pants uncomfortably tight. Still, her protest came suspiciously late. "Son, what are you doing?" she asked almost a full minute later, her voice suspiciously muffled.
"I'm massaging you mom," I answered, letting my fingers delve deeper. "I can get away if you aren't feeling comfortable, but I don't see the big deal," I said, my tone intentionally calm, like it wasn't a big deal for a son to molest his mother's ass. But in her addled state, she chose to take the statement at face value. She stayed silent, and I continued massaging her ass, getting a bit closer to her wet fold with every pass. A word of protest never passed her lips, even when my fingers brushed her sopping wet folds.
I could easily see that she was at the edge of a release, so I decided to finally stop my gentle approach, trusting the lust potion and her own overcharged state to do the rest. I sat on her legs, and pressed one hand on the small of her back to keep her sufficiently immobile. Then, I reached for my wand and cast a very low powered conducive charm to further disoriented her. I licked my fingers, and pushed two fingers into her pussy, burying all of my digits inside her. A shocked cry left her mouth, but I didn't stop even for a moment, my fingers slipping in an out without any mercy. "Son, what are-" she started, only to be interrupted by a moan. She tried to stand up, but the light pressure from my hand was enough to keep her in place. "Son, please- please stop. It's not right?"
"Come on mom, isn't it better than waiting until I was asleep then rubbing yourself until you fell unconscious. At least, by this way, you are receiving my full attention."
"You were awake!" she exclaimed in shock, not even bothering to deny.
"Yeah, I was," I said. "But don't worry, it's not a bother. It's not like we are having sex. It's just massage in a different way, and I'm always willing to help you, mom. You are precious to me." My last words, added to the already confusing cacophony she was suffering under, was enough to silence her completely. She just lay there, wordless, writhing under my fingers. Soon, and orgasm hit her with the full force, filling the room with her cries, her warm juices flowing around my fingers. Still, I haven't slowed down a bit, pushing my fingers deep inside her again and again without mercy. Seconds turned into minutes, but only moans escaped her mouth as I finger-banged her without mercy. Then, after the fourth earth-shattering orgasm, she finally fell unconscious. I made sure to put her panties and bra on, then dressed her in the negligee. Then I pulled the cover over us, wrapped my arms around her, and let the sleep to catch-up with me.
