Crazy Ex Girlfriend

My girlfriend at the time tabby got me to cum in her pudding one night saying it would be so sexy to sit and eat it infront of everyone without them knowing so i did especially as she said when they were gone we'd fuck all night, it had been a long week and I really wanted some pussy. So once I'd done my bit I brought it through hers her friends my sister then went and grabbed mine my friend's and his sisters. We sat ate joked and had a few drinks and my girlfriend kept looking and smiling at me even whispered in my ear that what we did was so fucking hot she'd suck my dick dry after I nut in her. Couldn't wait for everyone to go. As they were leaving tabby asked my sister to wait and whispered in her ear. The colour drained from her face and she started crying and when I asked what was wrong she said it's fine and ran to her car and went.
Tabby pleaded ignorance and said she'll probably be fine and to just wait till morning.
We fucked all night, she was more into than ever before and when I came she actually sucked me dry then dipped her finger in saying eating cum isn't actually that bad now she's tried it. Didn't think anything of it as I was beat and worn out from all we'd done.
Next day I get a call from my sister, she said that her and tabby had an argument the week before and tabby accused her of trying to steal my attention by always showering at ours after the gym and called her sick. Then said that when tabby was whispering to her she'd said that she'd swapped the puddings and she'd actually ate a week's worth of my cum because that's probably the sort of sick shit she loves. I didn't know what to say I apologised said I'd sort it and told tabby to get the fuck out that's when she showed just how crazy she really was. But I was done I packed her shit called her a cab and she was gone. Had a few issues with her for about a year but I'm glad she's gone my new girlfriend is amazing sexy funny and sane really fucking sane it's amazing
