Slut Sister Under the Table Part 2

(No requests for this one. Just felt like continuing this thread. Oh, and yes, I did use the same "coming" joke in two chapters in a row. I can do what I want.)

You look at your mom as your sister tongues your junk under the table.

You wonder about your suggestion to your mom and how far it really goes. Sure, you commanded her to ignore anything sexual going on, even things happening to her. Still, would it really work?

You smirk at the idea that pops into your head.

"Barbie," you say, "why don't you crawl on over to mom and put your tongue to work on her poor, neglected pussy?"

Your sister stops tonguing your genitals and you hear her crawling over to your mother.

"What the fuck now?" She moves over to your mom's legs. "Oh, fuck no. No no no, I will not be putting my mouth anywhere near my mom's old, hairy snatch." She seems to be fighting against her own body, to no avail.

You look up at your mom and she seems a little bored sitting at the table. She hasn't noticed her naked daughter at her feet.

"So, Mom," you start saying, "how's work going?"

"Hm?" She looks up from her phone. "Oh. Yeah, fine. Though, there's this problem with a project we're working on."

Mom changes position in her chair. You can tell Kelly is moving her mother's legs out of the way and getting closer to the pussy. You hear her continuing to grunt in protest, occasionally pleading with herself to stop.

"It just keeps getting delayed," your mom says. "We keep having to push back the launch day."

"Damn," you say. "That sounds frustrating."

As you and your mom make idle chitchat, you hear your sister under the table. "Ha!" she says in victory. "Even if I wanted to, I can't lick her. She's wearing leggingss." Still, you hear her grunting with a little effort. "Oh no," she says in a whimper. The next moment, you hear a rip tear in your mother's thin leggings. "No no no---mmf!" you hear your sister exclaim.

Your mom gasps for a moment, but continues talking with you, not seeming to notice anything out of the ordinary. You can hear your sister's tongue lashing at your mom's wet cunt. With each lick, you still hear her whimpering and groaning in disgust.

"I-It is," she she says with a soft moan. "It's so... mmmm, so fucking frustrating."

"I'm sorry it's not going so well." You tilt your head at your mom. "You alright? You seem a bit flush."

"D-Do I?" she feels her forehead. "I don't feel hot. Though I am feeling a... *gasp* God... a-a tickle in my tummy."

You frown at her. "Hm... Maybe you're coming down with a stomach bug."

"No, I think I just--- Oh, fuck, yes..." She shakes her head a little. "I mean, I think I just need to use the bathroom. I'll g-go after I f-finish... *gasp* Oh, mmm... A-After I finish breakfast."

You shrug. "Alright, then." You eat a bit more of your food and speak up again. "So what time are you heading to Connie's?"

"A-Actually," your mom says, barely able to suppress herself. "She's co-come... She's c-coming... Coming..." Your mom tenses up for a moment and lets out a loud gasp, then a sigh of relief. "She's coming to pick me up around 4."

You smirk to yourself. "Alright, Barbie, you can put mom's panties back where they're supposed to go. If you don't mind, go grab your shirt and put it on. I don't want you to get too cold."

Kelly comes out from under the table. Her face is a bit of a mess with your mom's juices. She looks utterly frazzled at everything she's done this morning. She gives you a smile. "Thank you for the juicy breakfast, Master." Her smile goes away in a blink and she covers her mouth in shock. She then hurriedly goes to grab her shirt, puts in on, and leaves the kitchen in a huff.

You reach down and pull your pants back on. You then look over to your mom. "You want me to take care of the dishes?"

"Oh, no, honey," she says. "I'll take care of them."

"Alright, then," you say. "I'm heading up to my room. I'll probably be leaving shortly."

You get up and start heading out.

Now, gentle reader, I have a question. Mom's previous magical orders included the following: "You will fail to notice anything perverted going on until your son says that he's leaving." That leaves a little wiggle room. Should your mom immediately realize everything that just happened? Or, should we just assume that the order was specific enough that she still won't realize what happened today at breakfast?

To simplify the question... Does Mom stop you or not?
