Author's Note: Continues after Fucking My Girlfriend's Aunt and Fucking My Girlfriend's Sister. Go read those first if you don't want to be lost. Contains lots of futa on female, and more lesbian incest than in those stories (but nothing super explicit). This will likely be my last entry in this story unless there's a lot of people who want to see more.

Jade crept around to the living room, underdressed, horny, and desperate to see if she could seduce the final member of her girlfriend's family. Her girlfriend Zoe's mom Nadine definitely appeared to be the most challenging of the three, and she had given herself an extra challenge: to have the milf's ass.
"Hi Nadine," Jade said, greeting the older woman who was picking up trash around the living room.
"Evening, Jade," Nadine responded nonchalantly. She tried to feign ignorance over what she'd heard Jade and Zoe arguing about. It wasn't until she turned around to look at the futa that she realized she was at least somewhat serious.
"Dressing like my sister now, are we?" Nadine continued as she gawked a bit at how underdressed Jade was. Her eyes drifted down to Jade's meaty bulge, but not for too long.
"Well, you know, if she can do it, why can't I?" Jade replied with a smirk, walking closer to Nadine.
"Sounds like you have...a few things in common with her," Nadine responded, moving away from the futa to pick up the last wrapper on the table.
"What's that supposed to mean?" Jade replied, feigning offense, but also genuinely curious.
"It sounds like whatever you're unsatisfied with about my daughter, that my sister could help you out with," Nadine remarked as she made her way to the kitchen to throw the garbage away.
"I-What, you heard all that?!" Jade replied, again keeping up with the act. She had grown accustomed to enjoying playing the clueless, dumbfounded futa as other women acted like perverts around her.
"You wanted me to hear that. If you need something like that, I think we both know she would oblige," Nadine continued from the other room as she opened the refrigerator to pour herself some juice.
Jade sprang up and made her way to the kitchen to confront Nadine. This was already going worse than expected, she thought. Zoe listened from the bedroom in anticipation.
"What, you're gonna tell me you're not interested in me at all? I've seen you checking me out ever since I moved in," Jade lied, hoping she might be able to break the milf somehow.
Nadine scoffed a little as she grabbed a glass, not even turning back to Jade. "According to your girlfriend it was usually the other way around," Nadine corrected her. "Not that it matters. It's not something I want to get involved with at all."
Jade's mind raced. She could feel herself losing control of the situation. On one hand, she was deflated - realizing this might be impossible. On the other hand, Nadine's confidence was sexy in its own way.
"Well, I know Naomi and Arabelle aren't into that kind of thing either," Jade continued, though she wasn't even sure of that herself.
"And what makes you think I would be?" Nadine countered, sipping her grapefruit juice and staring back at her daughter's girlfriend.
"I...I don't really know what you're into...Zoe says she's never seen you with anybody else," Jade replied, saying probably the first honest thing she had so far.
"And what, you think I've just been getting fucked in my ass while I've been at work, to use your crude language?" Nadine replied, looking directly at the futa, almost daring her to get aroused from the statement.
"Well, I...I don't really know...I just thought, maybe..." Jade stuttered. She started to regret even trying this - it was far different than seducing two obviously-willing participants.
"If I enjoyed that sort of thing, I would do it. But I clearly don't," Nadine explained, as she began walking towards the futa across the kitchen.
"But it sounds like you would," Nadine continued, as she looked down at Jade. The milf had a solid 4 inches over her, and had all the power right then. Jade swallowed, feeling unsure of what to say,
"I, uh, y-yeah, I mean...I like sex..." Jade replied, cringing at the words that exited her mouth immediately after.
"Oh, I'm well aware. But this isn't just about sex, is it?" Nadine corrected her, making eye contact with the younger futa the entire time, even when Jade tried to dodge her dark brown eyes.
"No, this is about fucking your girlfriend's mom in her asshole, isn't it?" Nadine interrogated, enunciating the profanity.
"I...I'm sorry, N-Nadine, I really shouldn't hav-"
"How disgusting," Nadine cut her off. "I don't say a word about your activities with my daughter, or what you do with the rest of my family. But that's not enough for you, is it?" She continued, having full control over her houseguest.
"N-no, I mean, yes, I love Zoe, she's the love of my life..." Jade helplessly replied. She hoped Zoe would run out of her room to rescue her, but to no avail. In reality, Zoe was a little satisfied at someone curbing her girlfriend's confidence, even if she didn't want Jade to feel too bad about it.
"That's not what I heard you two yelling about in your room," Nadine interrupted again. "You were talking about my ass. Do you want to see it?"
Jade froze. "I...No, sorry, I..."
"You don't want to see it? Last offer," Nadine replied seriously, once again looking the futa in the eyes.
"...Yes, I do want to see," Jade finally answered after a few seconds of silence and trying to read Nadine's expression.
Without a word, Nadine turned around, unbuttoned her slacks, and pulled them off, revealing a pair of loose black panties covering her ass. They were not particularly slutty or sexy panties, but her ass was so incredible that it was still a hot scene for Jade.
"Happy?" Nadine replied, turning around to look at the futa.
"It's...it's really nice," Jade admired, feeling herself getting hard again, though she had no idea when she'd be relieved (or by whom).
"Is that all?" Nadine pressed, still with a sternness in her voice.
"I...I was wondering if maybe you'd let me see more..." Jade's voice trailed off. She continued staring at the milf's ass, undeniably attracted to her.
"You want me to take my panties off and show you my ass in my kitchen, while my daughter's 10 feet away?" Nadine asked rhetorically.
"W-we can go...somewhere else, if you want," Jade replied. "Fuck," she thought to herself. "What a bad response."
"Oh, sorry then. You want to go into my bedroom, of my house, and have me take my panties off for you? That's what you want?" Nadine replied, as her voice turned to frustration.
