Drunken Mishaps

So years ago me and my bf had my sister round for drinks and there were a lot of them as she was staying the night. Lots of laughing and joking and I decided I'd give my bf a treat as it was quite early and I knew he'd have a 2nd run in him, and I was very drunk at this point and made him cum in my Baileys but without thinking I walked back through and put the drink down quickly stumbled back to the kitchen for my phone and returned just in time to see my sister finishing it.

It was an OMG moment but I just acted like it was all good and it really excited my bf thinking I'd just swallowed his load. Anyway later on I decided I wanted some more of my bf so pulled a blanket over us and started playing with him not realizing that we weren't covered properly and my sister had a full view of me rubbing his meat on my pussy, we were all ridiculously drunk at this point so I was a bit all over the place and she jokingly asked if I was to drunk to get it in and we all laughed. I remember deciding to just go for it and ride him and then I stopped and told my sister to give it a go practically throwing her on him as she was older and probably really needed good dick. Long story short she did and he came and he said she should share it and started scooping it out to feed me. Woke up the next day and felt rubbish she only remembered the sex luckily and my bf forgot she was even there so was surprised when the person he tried to wake up with his dick wasn't me. Never drank that much again.
