What's next?
Waiting for Diana
After my morning encounter with Stephanie, I can’t help but realize how lucky I am. Yesterday, Stephanie and Mom came over as a pretty standard visit and less than 24 hours later I already have Stephanie willingly blowing me to start our morning. To think, this amount of limitless power just dropped into my fingertips–well, to be fair, I am just sort of piggybacking off of Diana’s incredible invention.
I exit the fast-learning-machine-room (AKA Diana’s old lab) and see Mom eating breaking as she watches the news. To my surprise, she is dressed in an oversized t-shirt and undersized shorts. Growing up, this would have been one hell of a view; despite her clothes, her feminine figure is still obvious to even the most unobservant of eyes. As she looks at me, I can immediately tell that she isn’t wearing a bra either.
I never implanted any thoughts that required Mom’s nudity, I just made her more tolerable to the idea. Seeing as she didn’t pack, Mom just naturally grabbed a shirt from my room and shorts from Diana’s room. Neither of her clothes fit perfectly but that somehow makes her look even more perfect. The way Diana’s tight shorts create an extra sense of perkiness to her ass while showing off a good deal of thigh… and the way I can see the natural shape of her tits under the loose fit of my shirt…
I decide it would be best to get Mom into the fast learning machine so I can catch her up to Diana and Stephanie’s levels of degeneracy.
“Morning Mom,” I say to her.
“Morning. What were you two doing in there?” Mom asks about Stephanie and I.
“Oh nothing, just using the skincare machine is all” I responded. I know I technically don’t need to lie to her, but I instinctively feel weird telling Mom that I was getting some morning head.
After that brief exchange, Mom continues to watch the news and I fail to get her to the lab as she seems preoccupied with her meal. That is the one downside of the fast learning machine. Given the positive improvements that that thing has brought to my life I can’t be terribly upset or annoyed, but the size of the thing is pretty limiting by the fact I need to bring people to it.
As I think about this dilemma, I decide to have some fun. I walk over to Mom and begin kneading her breasts. Her tits are quite similar to Diana’s but also different. Mom’s breasts are slightly larger out of the pair and feel a bit foreign. They feel less perky but also more soft and malleable to the touch. I bounce Mom’s chest, making sure to be extra rough with her nipples until they are poking back into my hands.
Throughout all of this, Mom doesn’t react because, of course, her tits belong to me now.
It is at this point that I finally see Stephanie coming out of the shower wrapped in a towel. Because her programming actually makes her feel uncomfortable when others are naked but she isn’t, I watch as she takes a moment to survey the room. Once she sees that I am still naked from earlier, she dramatically lifts the towel revealing her gorgeous teenage body starting from her thighs and working her way up past her pussy to her tits.
I make my way over to her and begin groping her body. Just like I instructed, she doesn’t even react as I begin poking around her bubble butt. Though, I must deduct some points as I feel her asshole twitch as my finger prods its surface.
It doesn’t take me long to notice that her hair is almost impossibly dry. I know girls shower without washing their hair sometimes, but the level of dedication Stephanie needed to stay this dry seems unreasonable.
Things start to make sense when she turns towards me and I see her face is still covered with my splunk from earlier. Of course! I had Stephanie treat my cum as a compliment; she is supposed to keep it on her as some sort of perverted trophy.
“What is on your face dear?” Mom asks from across the room.
“Oh, it’s just cum,” Stephanie says.
“WHAT?! Watch your mouth young miss, those sorts of jokes aren’t funny,” Mom replies.
“No, I’m serious! It’s Tommy’s cum, I promise. It’s a sign of respect in his house,” Stephanie responds.
“Yeah, she’s telling the truth,” I say as I grope Stephanie’s slippery tits.
Hearing that seems to put Mom’s concerns to rest.
“Hmm, okay then. But still, make sure you ask your brother to shower with you next time. They’re trying to save water, dear. I had showered with Diana this morning before she left for work,” Mom says as her emotions come back down to Earth and she starts watching TV again. Fuck, what I would’ve given to see that
Mom’s current programming won’t let me do much else than letting me play with her tits. Hell, I haven’t even been able to see her ass yet–but I guess that is the fun of it.
I decide that we’ve done enough waiting around so I ask Mom to help me with something in the lab. Once there, I have her help me move around random boxes to make it seem like I’m not just trying to mind-control her or something.
Naturally, due to the convenient proximity, Mom asks if she can have another turn on the “skin care machine” to which I happily oblige. She sits in the chair, I lower the headset, enable the computer, and listen as the room is filled with a monotone robotic voice and the light cooing of my **** mother.
Before I get to work, I take a look at Mom. As always, being in a private room with a mindless woman is always a strangely intoxicating feeling. I’m not even doing anything to her yet, but just the fact she is here is enough to get me rock solid.
I reach to her thighs and try to peek up her shorts. Because they are so undersized, I can’t see much further than her than the top of her thigh. Nonetheless, I reach under and feel around Mom’s bush until I find her cunt. Just like her tits, her pussy also feels strangely familiar yet different.
I know I’ll have the opportunity for more, so I hold myself back as I begin to type. Right now, Mom tolerates a lot of the stuff we do but she doesn’t seem keen on participating so I decide that that is my main focus.
-Whenever someone says “Cantelope” in Thomas' house, you will begin to feel twice as horny as you currently feel.
-Sexual touch from your child feels 10x better than from anyone else
-When at Tommy’s house, you will always accept his offers to try the skincare machine.
As I hit the command to run the final lines of programming, Mom begins to stir.
“YAWN Did it work, dear?” Mom says as checks a nearby mirror.
“It’ll take a while for results, but it should,” I say.
“Hmm okay then,” Mom says as she gets up, presumably to exit the room.
“Wait- cantaloupe…” I say.
Mom stops in her place where I can see the hairs on her skin all stand at once. She turns to face me with a weird expression–Confusion? Excitement? Fear? I mean, all of those emotions are reasonable for someone who just randomly became twice as aroused.
“Sorry,” Mom says as she quickly bites her lip. “What was that?”
So from what I can tell, the trigger phrase works correctly. However, I really want to test the limits of this thing.
“I said cantaloupe,” I responded.
Here’s the thing about exponential growth, it gets out of hand really fast so I want to be careful here. Assuming Mom wasn’t horny a few seconds ago, she was probably feeling slightly horny after the first “cantaloupe” but still pretty standard overall. The second one should put her over the edge right where I want her–horny enough to take off her clothes if in a safe environment.
As soon as that word leaves my mouth, I can see her knees almost buckle for a second. She quickly catches herself and regains her composure.
“Sorry- umm,” she says with an evil smile.
I walk over to her and begin grabbing her tits–the one thing I can actually do with Mom whenever I want. This seems to have an effect on her as she completely forgets what she was saying. The only thing she seems to be able to focus on is her breathing as she shuts her eyes.
Mom has triggers that make her accept nudity, but I haven’t actually gotten her to bite on that offer until now.
I reach towards her ass and she doesn’t stop me as I begin groping her mounds of meat. Stephanie has the nicest butt out of the bunch, but Mom’s ass has a certain maturity that makes them appealing in a different way. Stephanie’s ass is like a kegstand–intense, fun, and the more there is the better. Mom, on the other hand, feels like sipping a fine wine–slow, sensual, and relaxing.
Mom was pretty horny from the trigger words, but after realizing that my touch feels 10x better than it would normally, she seems to be ramping herself up pretty fast.
Just as I’m about to rip off her pants, someone enters the room.
“Hey, why do you keep saying cantaloupe?” Stephanie says. Fuck… I forgot I made her act more fun and excited about things at my house. She’s already somewhat of an airhead, so now she’s just outright ditzy and her curiosity is getting in the way. “Hey, try saying that three times fast! Cantaloupe! Cantaloupe Cantaloup!”
Fuck.
Instantly, Mom clutches my entire body and begins grinding her dripping pussy on my legs. I can’t help but feel awkward as Stephanie stands in the hallway and watches. Despite social taboos being pretty irrelevant to her while we’re at home, I feel like her mind still probably doesn’t know how it should react.
“Please, somebody eat my pussy,” Mom begs as she takes off her shirt, revealing her voluptuous tits to me. Of course, I give them a hard smack out of respect before I return my attention to the room.
“Okay, if you say so,” Stephanie says as she rolls her eyes and the two walk over to the couch.
What? I watch in pure confusion as Mom bends over the couch as Stephanie struggles to pull down her oversized shorts. Suddenly it dawns on me: I programmed Stephanie to believe oral sex was a casual favor for all family members, not just myself!
Finally, Stephanie gets the tennis shorts uncaught from Mom’s womanly thighs, revealing her pussy to the entire room. This view doesn’t last long as Stephanie gets on her fours in front of the couch and begins licking away at Mom’s cunt.
I can tell Stephanie isn’t familiar with this act because I can see her slow down to really take in Mom’s taste to figure out if she likes it or not. Eventually, she ramps up but the whole thing seems pretty nonchalant to her–just as if she were scratching a family member's back.
Mom, on the other hand, is obviously in the middle of a life-changing experience. I mean, Stephanie probably knows her way around a vagina as she’s been on the receiving end, but she can’t be THAT good at this. But she also said cantaloupe who knows how many times, and her touch also feels 10x better to Mom so it does make sense.
I walk over to them and Mom isn’t even reacting to my presence; she is totally engulfed by the sensation of her daughter casually munching on her baby maker.
Hey, I love watching girls get dirty as much as the next guy, but I’m not gonna just sit here watching. Seeing as I can’t get Mom’s attention long enough to ask her to suck my dick, I avert my attention to Stephanie.
The last time I implanted triggers into her, I made her unreactive to where I touch her. I decide to test the limits of this as I position myself in a kneeling position at her rear and “touch” her with my cock. As expected, she doesn’t react.
I take this to the final step as I slide my dick into her vagina. She is getting wet from the situation and physical stimulation, so her pussy feels great. However, none of her implanted triggers make this situation explicitly arousing–she’s just doing a favor to Mom and being as unreactive as she can to me–so she feels a little less “receptive” than Diana’s pussy felt last night.
This whole scene is perverted enough as it is, but the fact that I know Stephanie was at home yesterday living her normal life adds a little fuel to my fire. I clap Stephanie’s fat ass like it deserves. Stephanie is this sweet, wholesome figure in my life and I love her to ****, but she really “looks the role” of a slutty blond well. I wonder if that’s how she acts at school.
As I continue to fuck the hole in front of me, I don’t know what to look at: my peppy sister’s fat ass violently shaking or Mom’s spasms as she tries her best to handle Stephanie’s head.
Fuck it, right?
“Cantaloupe, cantaloupe, cantaloupe!” I yell out, almost tripping over my words on the tongue twister.
Mom was already getting there, so increasing her arousal by 8 times may have been a little overkill.
Instantly, Stephanie is flooded by a stream of Mom’s cum as she moans loudly into the apartment. Stephenie tries to move out of the way, but Mom’s legs tense up and lock Stephanie’s face tightly in place against her snatch.
This sight is enough to instantly send me over the edge as I feel my entire body begin to tingle. I fire load after a load of my thick, creaming semen deep within Stephanie’s cunt.
A part of me feels bad that Stephanie is enduring 2 streams of cum, but, just as I begin to feel myself die down, Stephanie begins bucking back against me as if she were trying to milk every last drop of cum out of me. Somehow, she is successful in prolonging my orgasm.
She isn’t supposed to be reacting so that I don’t have to deal with the negative consequences of groping her, but I suppose she’s become so horny that she’s now reacting positively toward me by her own free will (in combination with the fact she basically has no moral compass right now).
And fuck… to Stephanie, the more I cum just means more positive reinforcement for her since she takes it as a compliment. I inadvertently pavloved Stepanie into being a cum slut so now she’s getting off to the fact that I’m cumming in her. I feel her orgasm as her pussy begins to pulse around my dick and a mixture of sexual fluids begins to leak out of her pussy.
At a certain point, Stephanie and I form an unspoken competition to see who can outlast the other; just another form of siblingly rivalry.
The harder I fuck her, the harder she pushes back against me. God damn her athletic hips are putting me to work!
Throughout these 10 seconds, her vagina becomes an absolute waterfall consisting of our special mixture. And while Stephanie and I battle, Mom comes out the real winner as Stephanie eats her pussy with greater rigor free of charge.
Eventually, Stephanie and I are fucking so hard that she is no longer on all fours and her entire crotch is being slammed flat against the floor. Stephanie uses her strong build to keep herself in optimal position to continue eating out Mom’s pussy, though at this point Mom is pretty much done as she starts to slide deeper into the couch.
Eventually, my dick can’t handle any more as I let off one last, power thrust upon Stephanie’s loins. Either due to fatigue or competitive respect, Stephanie chooses now to call it quits too.
She rolls onto her side, has me lay under her with my back against the carpet, and then finally lays back on top of me. I give her soaking ass a nice squeeze as I feel her tits press up against my chest. With her now looking down at me, I can’t help but notice how cute yet terrifyingly sexy this girl was. Even with her face covered in a layer of Mom’s cunt, I can’t help but resist moving in for a kiss on her cheek.
Then, Stephanie closes her eyes and begins to coo--at which point I figure she’s knocked out--with me following seconds after. Though I’m sure if you were to ask her, she’d tell you that I fell asleep first.
