She asks for a favor

Things seem to die down over the next few days. When you saw Jane the next day she seemed pretty hungover and out of it. She didn't even want to do anything sexual for awhile, despite how horny she was acting at the party. It must have been pretty crazy because she didn't seem to fully recover till halfway through the week.

Late in the week when she was out shopping, you suddenly get a message on one of your chat apps from an account you don't know. You check it and out and it turns out to be the girl from the party, Cheating Jane.

"Hey John, this is Cheating Jane haha. Jane told me about her name for me and gave me your messenger when I asked. I was wondering if you'd be willing to do me a favor?" You're a bit surprised to hear from her, more so that your girlfriend would give this girl your contact info. You are intrigued as to what she could want from you though.

"Sure what's the favor? Happy to help friends of Jane anyway I can," You reply hoping it's something small you can get done easy and get on both their good sides.

"Alright so you know I just started cheating on my boyfriend and god it's been amazing I had forgotten how good sex can be. I've been getting fucked so much this week he's barely gotten to touch me, but I think I'd have fun really rubbing it in his nose which is where you come in. I don't want him to find out and ruin our relationship, so I want you to pretend to be my boyfriend and I'm going to rub all my cheating in your face. I don't want your permission or for you to be happy about it I want you to react just like if I was a unrepentant cheating slut that you're too much of a pussy to leave." You read that a few times just to make sure you're understand it. You sit there a bit stunned at this request, this girl is kind of messed up but you can't help but be a bit intrigued.

"Did you tell Jane about this? She can't be alright with me acting like some other girls boyfriend," You reply quickly not wanting to upset Jane and have her mad at you for doing something like this with one of her friends.

"Oh yeah, she was actually the one that suggested you. She thought you'd be the perfect fit for what I was looking for, especially since you and my boyfriend share a lot of friends. She gave me permission to send pics and video so you get something out of it but she said you owe her some nice nights out." You sit there stunned for a moment not sure what to think, it's not often your girlfriend suggests another girl pretend to be your girlfriend and send you sexy pics and video even if it's under pretty messed up circumstances.

After some deliberation you decide to go along with it. "Alright I guess if Jane is ok with it and thinks it would be a good idea I'll do it." You don't have to wait long before her next reply.

"Haha great it's going to be so much fun rubbing in your nose how much better all your friends are at fucking you little slut girlfriend. You know you have pretty shit taste in friends as soon as I told them I was going to start cheating they were all over me sending me pics of their cocks and telling how they were going to fuck me, damn though you do a pretty good job of finding guys with big cocks if we break up I'm going to have to stay friends with you just to have you find big cocks for me. Like Jason, I'd have probably started cheating on you years ago if he had shown that thing to me." Wow she wasted no time getting into the role despite yourself you start getting turned on a bit. You try to think of how you'd act if this was your Jane.

"Yeah I saw in the pics of that night, kind of made me feel like you were just rubbing it in after awhile. Kind of made me feel a bit inadequate since you've never acted like that with me" You don't have to wait long before her next reply.

"I mean you saw that cock, hell if you cheated on me with him I'd have to understand. Though you have been sleeping in his cum all week we've been fucking every day this week in your bed, Katie from the party even came over one day to join us. Her pussy tasted so good, too bad for you I didn't realize how fun another girl could be till now hehe."
