Happy Wife, Happy... Other Wife

"What the hell are you doing?!" Louisa whisper-shouts while leaning away from the phone I shoved in her face.

"What was that, babe? I didn't hear you," Phoebe's voice calls out from the phone, causing Louisa to once again panic.

"Go on, Louisa. She's waiting. You said yourself that she would understand," I tell my professor.

Am I being needlessly cruel? Yes. Could I have probably made this plan work using a much safer method? Almost certainly. But that's just not as fun. Call it sadistic if you want, but something about seeing the look of betrayal on Louisa's face is really making my blood pump. Though, to be clear, I do still hope this plan works out for everybody in the end. As much fun as it is to make my teacher sweat, ruining a marriage would probably kill the mood. Luckily, I feel pretty confident that this is going to work out.

I watch as Louisa scrambles to figure out what to say. She knows she can't just hang up the phone at this point. Eventually, she does move closer to the microphone and begins speaking.

"H-hey, baby. It's sweet of you to offer to come over, but I think I'll be alright. You just- Mmmmm!" She can't help but make a guttural noise as I slowly push my cock back into her ass as she speaks.

"What was that?! Are you sure you're okay? Look, I know how on-edge you've been recently. Please, just let me come over and try one more time," Phoebe tries to insist.

"NO!" Louisa accidentally screams as I pump into her. "I-I mean... I promise, I'm fine. In fact, I'm starting to feel -AH! - better already."

"What's going on? You keep making weird noises."

Phoebe's voice is starting to sound more and more concerned. Given how sexual of a person she is, it probably won't take much longer for her to figure out what's going on. But just to be sure, I decide to make things a lot clearer for her. I reach a hand back and smack Louisa's ass, letting a loud slapping sound echo throughout the room. I momentarily get lost in her asscheeks as they jiggle around from the **** of my hand. It's a mesmerizing sight. The only thing that snaps me back to reality is the sharp breath Louisa takes immediately afterward, reminding me of what I was supposed to be doing.

"Yeah, you like that, don't you, slut? I bet my dick feel real nice stuffed up inside of you," I project just loud enough to ensure Phoebe can hear me.

Once again, Louisa's eyes nearly jump out of their sockets. Her jaw drops, though that only ends up making it harder for her to stop her moans from coming out.

"W-w-what was that? Louisa... what's going on over there?" Phoebe says.

To someone who doesn't know about her new identity, Phoebe's voice probably just sounded scared. But to me, it came across a little differently. There was definitely a nervousness to her tone, but there was also the slightest hint of arousal mixed in there. Even if she doesn't know exactly what's happening, just the potential of being cucked over the phone is enough to start getting her turned on. And that's the key to this plan. If this situation was caused by her first attribute, then I'm going to use her second one to get out of it.

Now it's time for the next step. Without warning, I pull out of Louisa's ass. As my cock exits her back door, she can't help but let out a small whining noise. She looks back at me again, fear still in her eyes, but this time it's for a different reason.

"W-wait... no... please put it back in..." she whispers desperately.

"Tell her," is all I respond with.

"Huh?"

"You're not getting my cock back until you tell your wife what's going on. In fact, if you don't, I'm going to walk out right now," I threaten.

"Louisa?" Phoebe calls out again.

Louisa glances back and forth between me and the phone, seemingly weighing her options. It goes to show just how horny she is that even after all we've done so far, she's seriously considering telling her wife the truth just so I'll put my dick back up her ass.

"I... I... I'm getting fucked up the ass by one of my students..." Louisa finally manages to get out.

"W-what did you just say?" Phoebe asks, her breaths starting to get heavier.

Just before Louisa has the chance to speak again, I shove my cock back inside her asshole.

"AH! I SAID MY STUDENT IS ASS FUCKING ME! I PROMISED TO BE HIS ASSWHORE BECAUSE HIS COCK FEELS SO GOOD INSIDE ME! OH MY GOD, IT FEELS SO GOOD! I'M CUMMING AGAIN!" Louisa screams into the phone.

The next minute or so is just filled with Louisa's sounds of pleasure as I thrust deep inside her. Once she starts to calm down again, I can hear that Phoebe's breathing has gotten even deeper. A look of horror comes over Louisa's face as she realizes what she just admitted to. However, before she can say anything, Phoebe says something that I don't think either of us were expected.

"Wait, did you just say 'his cock?' Are you fucking a dude right now?" She asks with genuine surprise.

Guess that confirms that Louisa is gay, in case there was any doubt. Or at least, that she was gay. I'm not really sure what she would consider herself at this point.

"That's right, Phoebe. Your wife can't seem to get enough of my cock right now," I decide to chime in as I turn speakerphone back on.

"Wow... I can't believe- wait, I recognize that voice. Do I know you?" Phoebe asks me.

"We've met a couple of times. The name's Matt, though you might now me better as 'hot stuff,'" I reply.

"Hot stuff... hot stuff... Wait! Are you that guy I bumped into last week after coming to the school to see my wife?"

"Bingo."

"Damn, Lou. Not a bad choice for your first dick."

Louisa is having trouble keeping up with the conversation as she continues to cum as I fuck her. It's honestly impressive how many times she's orgasmed at this point. It's also impressive just how... relaxed Phoebe seems right now. I can still tell there's some tension in her voice, but she doesn't seem all that upset anymore, which is good.

"S-so... um... h-how is her ass?" Phoebe asks out of nowhere.

"God, it's fantastic. I'm a bit jealous that you get to spend so much time with it. Maybe I'll just steal her away from you so I can have it all to myself." That's probably a risky way to phrase it, but I need to make sure I keep pushing.

"O-oh fuck... that's so hot..." I just barely hear Phoebe whisper from over the phone.

That's when I notice a soft squishing sound coming from the phone as well. I have no way of knowing for sure, but I think it's probably safe to assume that that's the sound of Phoebe fingering herself. To help encourage her, I set the phone down on the table and pound into Louisa even harder. She gasps and moans as I do, which in turn evokes some quieter moans from Phoebe.

I don't really have a way to know when Phoebe climaxes, so I just settle for fucking Louisa until she gets it all out of her system. It takes a bit, but eventually, she collapses onto the table in complete exhaustion. Once that happens, I pull out and bounce my dick on her ass a few times. A few hits later and my cock erupts all over those sweet cheeks. I think caking that hot lesbian ass with my cum might be one of my proudest achievements now. Anyway, with Louisa finally sated, I decide to turn my attention back to the phone.

"Did you enjoy getting to hear all of that, you little cuck?" I tease.

"Wha...?" Phoebe responds in a dreamy voice. "Is it over already? Uh, I mean..."

"It's okay. You don't have to pretend that you didn't like it," I say before turning my attention back to Louisa. "You know, I think the two of you have some things to discuss, so I'll get out of your hair. Louisa, make sure to give her all the juicy details about everything we did. If I find out you did a good job, maybe I'll take your ass again. Hell, maybe I'll even let your wife watch next time..."

Both women make some kind of noise, though it's hard to place what either of them are. What I can tell is that both of them are turned on by the idea, Louisa at the thought of getting ass fucked by me again, and Phoebe at the prospect of getting to watch.

"Alright, I'm going to go ahead. I'll see you in class, Professor. And remember, don't leave any details out," I repeat before walking over to my clothes.

I quickly get dressed and make my way out the door. Right before I leave, I see Louisa manage to stand up (thought her legs are clearly wobbly) and pick up her phone. She puts it up to her ear and starts to talk, though what exactly she's saying I can't hear. I'm sure both of them have a lot to talk about, and me being here isn't going to help them at this point. I set all of this up, but they're going to have to work out the rest themselves. Still, I do have a good feeling about what the results are going to be.

With one more woman under my belt (one that seems like a particularly impressive accomplishment, all things considered), I walk out of the room and start making my way back to class. As I do, I can't help but imagine what it might look like to have Louisa and Phoebe together in the same room. I may have only known about their relationship for a short time, but my mind is already being flooded by the possibilities.
