So my sister go married last week and she was ecstatic about it before hand but also visibly stressed. My mother assured her over the phone that she’d be fine, mom had her on speaker as I was behind her. They talked about mother daughter stuff that didn’t really bother me and I’d keep quite whilst trying to make her moan which resulted in a few dirty glares from mom.

As anyway sis wanted to do a family catch up (so just mom, sis and I ) before the big day. Mom asked what for and she said that she needed to let off a little steam, this is code for family fun time when her partner is around, which we haven’t done for a while.

The following day I asked mom to call in sick the day we were all catching up so I could put my plan into action. After a bit of convincing and showing her my gratitude she agreed. After I did all that I coordinated it so we would meet up at mine and mom would say she was having car trouble and to start without her. This would be 2 days before her wedding.

The day arrives, sis rocks up and goes straight for the vodka, I come up he hind her and start kissing her, she tells me to wait for mom and I just she her the text I had mom send me. She starts to relax a little as I ask her to screen mirror some porn onto the tv, she quickly puts some hour long “best bits of porn” vid. Not long after we are both making out.

To make a long story short, making out turns into strip games, those turn into sex games, which then results in us not caring about anything and fucking till I’m close. I tell her I’m close and that I’m not gonna pull out and she just straight up leg locks me and says whilst looking me dead in the eyes “Good”.

By the time I’ve recovered and we are having round 2 mom shows up, drunk as hell, see’s us mid fuck and just asks with a dead pan expression if we are making her grand babies, I don’t even have time to think when I feel my sis tighten up in a way that makes it feel like she’s milking me and respond with “fuck, I hope so”.

Later I found out that mom told sis my plan and was all game for it, to see if my swimmers are stronger than his was her reasoning. This resulted in me fucking her minutes before I walk her down the isle and with mom sneaking her away afterwards for what she said “was a generational tradition” aka mom eat sis out.

Now we play the waiting game as she’s on her honeymoon
