You can find the context here and here

After the first time I showed her friend (the events of the last post) we had long talks for a couple of days, it took longer for her friend to get used to this and I learnd that she's very close to my beta and as such it took time. After a lot of talking about it, I decided to show her her friend just how much of a pig the beta actually is. We set a date twice but she bailed and the third time she finally agreed, all three of us went out for food and the whole time I kept degrading the beta, passing humiliating comments and bullying her. Like always I made the beta pay and when we reached I made sure once more that the friend was on board.

Told the beta to remove both our foot wear and clean our feet after we came in, made her kiss her friends foot a few times. Then I told her to kneel with her hands behind her head as I kissed and made out with her friend for a while and told her to sit on the couch. I slapped the beta a few times and then pissed on her while telling her to look at her friend and when I was done I told her to lick it off the floor. Her friend was pretty disgusted and I made her voice it, telling her how disgusting of a slut the beta is. The moment the beta was done licking her piss off the floor I told her to remove my belt for me and I whipped her with it a couple of times. I'd told the friend the beta likes this but she was taken aback and surprised. I stopped whipping the beta, told her to kneel and tell her friend just how much she likes this and told her I won't whip her till her friend says I can. The beta started telling how much of a slut she is and when I asked her friend if she's okay with me whipping her I got a "i don't think so, it's all a lil too intense for me". Then the beta started begging to be whipped and beten but I told her firmly it's her friend's choice and she got to begging her.

For the next ten minutes or so she kept begging her friend to let me hit her, let me piss on her and humiliate her. She got completely naked and was kissing her friends feet while begging her to be abused. Her friend would walk around, try to talk to her and all the beta did was beg. After another 5-10 mins or so she finally agreed and I told her I'll do it only if her friend spits on her and that took another 5 mins of begging but she did it and I took my belt and started hitting her and she kept thanking me the whole time while crying.

When I was done we had things to drink while we watched something, sitting on the couch while the beta sat by our legs. Giving her messages, licking our foot etc. After a while i fucked her friend while she kept kneeling down, was rough with her and spanked and slapped her around a bit. When I was done the beta licked my cum from her friend, made her stop midway and asked her how badly she wanted it and when the beta said she'll do anything I told she can lick the rest of the cum off for a hundred whipp or spanking, whichever I felt like and she readily agreed and proceeded to lick my cum off her friend

Note: idk how to abbreviate their names, it's a lil unique and I don't want to use just "A" and "G" so you're stuck with a hard to read format, unless you can suggest me something else.
