Your mom is mute with shock.

"Oh, hey Mom," you say to her, as though she caught the two of you studying for a history exam, rather than finishing up an incestuous fellatio session. Again, the nonchalance sends a ripple of excitement down your spine.

"Hey Mom?" she repeats, incredulous, her eyes darting back and forth between you and your sister. "Sam, Laura... what..." She can't get out any more. She's nearly vibrating with shock, her mind simply refusing to comprehend the visage before her.

You sister gets to her feet -- still completely nude, of course -- and your mother looks away, staring down at the floor. "Mom, what's wrong?" she asks, a drop of cum still on the corner of her mouth. She bears an expression of genuine worry; as far as she's concerned, this is totally normal, and she can't understand why your mother would be reacting in this way. "I'm just blowing Sam, like usual! What's the problem?"

You decide that it's probably best that you don't give your mother an aneurysm or a heart attack or something from all of this, so you take action. Looking at her, you say, "Yeah, Mom, Laura and I have sex with each other all the time. We all do. What's the big deal?" The Manipulator's light shifts again, now a yellowish-orange, and you can feel it leech some energy out of your body to perform its task. But it's a fair trade, as your mom looks back up at the two of you, her expression changed. She's still upset, but there's no indication of shock on her face anymore. Instead, there's something else that you can't quite place.

"The big deal," she replies to you, "is that the two of you didn't let me know you were doing this!" It's then that you realize what her face is conveying: rejection. Holy shit, you think, she's actually disappointed that you didn't invite her to join in! "You two are free to fuck each other whenever you want, of course, but it would be nice if we could spend some family time together every now and then."

"Oh, Mom," Laura says, her voice laden with sympathy, "I'm sorry, I didn't even think to ask you if you wanted to fuck! I just had a hard day, and needed Sam's cock so badly." That gets you going, and you feel yourself getting hard again despite the toll the recent blowjob and manipulations have taken on you. You've never really looked at your mother that way -- surprisingly, since you look at damned near everybody else that way -- but you realize now that she's an extremely attractive older woman. Her figure is pleasantly round, with wide hips ("childbearing hips", you muse) and an ample chest. She's wearing what could only be described as "mom clothes": high-waisted, loose-fitting "mom jeans" and a simple pink blouse. You're suddenly struck with an irresistible desire to learn more about her. You've always been the intensely curious type, after all.

"I'm sorry too, Mom," you agree, and you actually do mean it. "But... I'm confused. Why are you wearing clothes inside the house? Were you planning on going out or something?" Now the Manipulator's light shifts definitely to the reddish-orange, and a wave of fatigue washes over you. Oops, you think, that might have been a step too far. You're pretty sure that, whatever happens next, you aren't going to have much energy to do much more than observe.

As though she just realized a shocking faux pas, your mom looks down at herself and gasps. "Oh, I'm so sorry!" she blurts out, quickly starting to unbutton her blouse. "You're absolutely right, it's inappropriate for me to be dressed like this around you." The blouse slides off of her shoulders, revealing a simple, practical, white cotton bra. She tosses the blouse onto the pile of your sister's clothing. Next, her hands move to the metal button of her jeans. "In fact, I have no idea why I'm wearing this stuff anyway; it's not like I was planning on leaving the house." After a quick zzzip, she sticks her thumbs under her waistband and wriggles her hips, letting the jeans fall to the floor. She steps out of them, picks the up, and throws them too onto the pile; even in this state, she's trying to keep things tidy. When she straightens up, you see that her white cotton panties match the bra: plain, comfortable, and conservative.

Next, she raises her arms over her head, unclasping her bra behind her. Lowering her arms in front of her, the bra falls free from her large, pale breasts. They sag slightly, age and gravity having taken their toll, but they're still absolutely magnificent. (Again, you briefly muse that you've never seen a pair of breasts that weren't absolutely magnificent.) You are a bit surprised to find that she has very dark brown nipples, with large areolae surrounding each -- you hadn't expected that. You also find it interesting that the site of her naked breasts is entirely unfamiliar to you; a part of you assumed you'd have some sort of vestigial memories, buried deep inside, of nursing when you were a baby... but nope, apparently that's not the case.

Her thumbs now inside the waistband of her panties, your mom bends over, causing those soft, inviting, ivory pillows to hang low, naturally assuming conical shapes that end in those large, brown circles. She slides the panties down over her legs and steps out of them, revealing an absolute forest of nearly-black, curly pubic hair. She obviously doesn't trim or shave in any way; why would she? She's a widowed housewife, content to remain at home, never really interested in going out and pursuing new relationships. You don't mind one bit, as again, it's the variety that you find alluring and exciting.

Straightening up, and now fully nude like the two of you, she smiles, and walks over to the couch, standing before the two of you. "There, that's much better," she says. Glancing at Laura, she points to her own mouth and says, "Honey, you still have a bit of cum on your mouth, right there."

Your sister runs her finger along her lip, picking it up, then licks it off of her finger and giggles. "Oops, sorry!" she replies, and her mom smiles.

"I'm sorry again, you two," your mom continues, "I don't know what came over me."

"Oh, don't worry about it, Mom," your sister replies, as she sits down beside you. "It's not like we don't see you clothed when we're out all the time!" They both giggle a bit at that, and you can't help but smile too at the absolutely surreal inversion of normality occurring around you. You're about to open your mouth to suggest the next course of action, when you are overcome by an enormous yawn.

"Uh oh, looks like you wore your brother out," your mother smirks at Laura.

"Tell me about it," Laura replies, rolling her eyes. "He couldn't even last fifteen seconds with me today!"

Your mother gives you a look of mock outrage. "Sam," she cries, "I expect you to do a better job than that!"

Again, you're about to reply, when another yawn overtakes you. You realize that the device has drained a ton of energy from you, and before you pass out from exhaustion, you want to learn more about the thing. So you stand up. "I'm sorry, you two," you say, "I don't know why, but I'm just so sleepy right now. I'd better head upstairs."

Laura smiles, looking at your mom with a mischievous smile, one which your mother returns. "Oh, don't worry, bro," she says. "I'm sure we can keep ourselves entertained in the meantime."

You really, really think hard about just sticking around and observing what'll happen next, but you know you have some mysteries you need to unravel first, so you nod, walk around the couch, and out of the room. As you do, you can hear gentle mmmm sounds behind you, causing your cock to twitch.

Patience, you tell yourself, there will be plenty of time for that later, as you ascend the stairs up to your room.
