Breakfast

You did need to talk with your mom about Stacy and figure out what exactly was going on with her. But when you knocked the door was opened by Stacy seemed she really was wasting no time. She really only exposed her head to you but just as she was about to speak her hand went to mouth as her expression turned very quickly to surprise before it turned into a pained one then one of pleasure. "W-hgnn~" She let out a long groan from behind her hand. Any suspicions you had were cleared when you realize she was bent over and you were looking downward, then looking up as your mom's head was now visible as she spoke to you "Oh, she just needs a bit of time to get used to... arrangements" Then continues speaking casually to you explaining to you that making some omelets should help her to adjust.

She even took you step by step on how to make some, but you weren't paying attention as Stacy's face betrays she might have been a bit over-confident in suddenly rushing in your weird relationship. But then it converts to pleasure as her head jerks, seems your mom started to thrust and thrusting quite hard as you can hear the loud slaps faintly. She does excellently at blocking her moans but she can't stop them all. Eventually she collapses unable to hold herself up and your mom catches her by the neck preventing her from falling, still cant see what exactly was happening beyond the door but you can only really think of one reason why you weren't allowed into the room.... Ellie must have been in there as well. "Just do that and it should be good" Your mom says quickly before slamming the door shut.

You heard her stop holding back on her moans a bit as you can hear her through the door "OH MY GOD PLEASE, RUIN ME." She shouted but the next part was not shouted luckily they were right next to the door "Make it so I can no longer enjoy any cock but yours" and then no more noise but after a few seconds you heard her moans start up again but further away.

You did try to open the door to peek but it was locked, with nothing else you head to the kitchen to make omelets like she asked. She knows you already know how to make them the explanation was just service for you as she could fuck her without Ellie being suspicious that you know what's happening.

In the kitchen you could hear the moans faintly from the ceiling and just as you were finishing up your mom strolled into the room and immediately she comes to you and when she hugs you, its becomes apparent that her cock was in that same super excited state from before immensely rock hard and from the smell with her cum being extra potent. Just the scent despite being in her clothes has you drooling for a taste of that cum. "Well, There's no reason to hold back anymore. With Stacy around I can get my relief, the main reason was because when it is in this state I need to be relieved once a day now I can relax more and just enjoy." She lets out a happy sigh practically humping you with her cock that was stuffed up her shirt to hide its immense size and constant hardness.

You realize she has been constantly forcing herself to remain soft... until now. She was probably going to relax after she managed to get your Girlfriend and use it on her, but with Stacy around there's no reason to hold back and will probably use it to claim your Girlfriend instead. You felt her hands pushing your head onto the tip of her cock, almost causing you to rip open her shirt and start servicing it. But you don't get the chance when your Girlfriend comes in supporting a wobbly legged Stacy who was beaming with happiness or well pleasure you guessed.

Your mom realized the state you were in and seats herself in her usual spot. After breakfast your mom did a happy skip out of the room looking significantly less stressed than normal. Your Girlfriend followed after her and you were left with Stacy. Not wanting to deal with her teasing you decide to clean up the kitchen. But that just let her spread her legs and pull up her skirt, just like Katie It was gaping greatly. Even from here across the room you know you could easily put your fist in there with no effort. She looked nothing like she did last night.

She doesn't say anything as you clean then your mom sends you a message its a video, you play it immediately it was your mom on her bed and Stacy about to lower herself on your mom's cock. Her cock wasn't at the extra large size it is at now, but then they freeze as you heard a knock from the door. That's when you realize that this was this morning when you knocked on the door. If you didn't know before that the cameraman was your Girlfriend her noise of surprise at the noise confirms it.

And sure enough when Stacy went to the door to speak with you your mom sneakily followed and just as the door was opened shoved her cock fully into the poor girl. Then your mom leaned forward to talk with you and started her rough thrusting. Then there was the part where she could no longer hold herself up and collapsed, or well more like she was cuming her brains out and trembling as your mom was supporting her from falling completely by gripping her neck with a hand and pulling her back onto her cock. Then the door was closed and her pleading shouts for her to ruin her was heard, and they move to the bed with your mom carrying the girl on her cock.

You note that Ellie never moved the camera from the door as they started again this time on the bed, before you realize that you could see your shadow under the door making it obvious you were still standing there, but then your shadow was gone and you heard Ellie let out a heavy sigh in relief.

Then a hand grabs your phone, it was Stacy now standing next to you before she taps awake at the video then passing it back. "Here this is the important part" She surprised you, you were not expecting her at all but you still click play and this time Ellie was much closer to them letting you hear their whispering.

In the video Stacy begged her for her to be rough and that she needed more and to your surprise before she can even finish her sentence your mom says "Well, there is one thing I can do... but it's not your choice. Ellie, You remember how large my cock was the other day with Katie? I can let my cock always be like that but of course, you'll have to deal with it as well."

Your Girlfriend didn't even ponder or take her time to decide "Yes, I'd love that." Her voice heavy with her own lust. The camera was briefly not facing the correct way but you heard your mom speak "Ah~ that's much better. This is actually my normal state, so this is actually much easier." Stacy started to let out moans despite the fact your mom isn't moving in her at the moment.

Then the camera answers your questions as it focus's on where they are connected. Even you are amazed when you see that the small slit that was there was being forcibly opened there wasn't any cum so you could see how it was already transformed even seeing her pedals that were hidden before. But then your mom started moving again, those lips of a pussy being pushed inwards as the cock moved inward, but then pulled out as the cock was slid back. With something like this it's no wonder why her pussy wouldn't be transformed as her pussy was being destroyed.

Your mom started to cum when it was at its deepest, unlike before she slowly pulled her hips back giving more and more room for cum then her cock was out of the pussy, it drooled the cum that filled it perfectly. She then released more cum the first splashing around the pussy, then your mom slowly moved her cock up and sprayed the rest over her belly, her small breasts, and her face before it finally came to an end.

Your mom grabbed the phone from Ellie wordlessly as she told her "Why don't you clean her up and join me in the shower after" Then she points the camera at your Girlfriend now with her face buried between the limp legs, taking mouthfuls of that cum you know is incredibly addictive from personal experience. The last thing you saw in the video was your mom's now monstrous cock from above with your Girlfriends back in the background, a few drops of your mom's cum on her back here it dripped from the end.

By the end you forgot about Stacy completely as when you look up she is just grinning at you before she awkwardly walks away her legs unable to be as close together as before.

You finish cleaning right away and when you exit the room your mom is there on the couch with Ellie in her lap. Your Girlfriend smiles at you gently, with a hand over her chest. Your mom speaks then "Why don't we watch some movies all day, we haven't spent some time like this for a while." Your mom's grin to you promises that she would very much enjoy it. As Ellie looks at her in surprise before looking very nervously back at you.
