I have been texting with my wife's sister for a while as she was asking for advice on things that she didn't want her sister to know. One thing led to another and it got lewd and we started sharing some intimate details and I (a typical giver and people pleaser) started just telling her anything she wanted to know. My secrets my closest bi adventures my paypig phase and she was enjoying it.. she joked about how she can just tell her sister all of this unless i do as she says, we ended up sexting about it. A couple of days later she sent me a text telling me to run an errand for her, it was unusual she doesn't ask me that usually so i just said sure maybe when am done with somethings? She said ok but today or else lol.. i told her wdym? She said well i can still share all those texts with my sister! I was in a rollercoaster of emotions.. it was hot af but too real cuz like wife doesn't know 99% of what i shared with her sister.. which made it even hotter but scary. She has been doing this for a couple of months now and even getting me to buy her stuff sometimes.. it is still ongoing, not everyday though. I am both scared and excited about the whole thing
