Hello Reddit!

Happened last Year summer

Not the best of day for summer weather, at my girlfriends house decided to go watch some GoT (had to catch up on season 4).

Now a problem we got here is that her sister always likes to watch with us, so were in my girlfriends bed, and so I lay on the left, and my girl is on the right, and now for some reason her sister decides it appropriate for her to jump in the middle, now mind you her sister always watches TV laying on her stomach.

So I'm sitting here slightly squashed up watching GoT, and I tend to always squeeze my girls leg when were watching TV or anything, so I'm here casually squeezing her leg, and slowly going up, and then BAM  "Can you stop touching me" ...yes, her sister said this, but she said it to my girl for some reason LOL, assuming she was touching her leg,  I had just realised all this time...I had been groping her Sisters upper leg the whole time, I sneaky pulled out my hand from the upper side to make sure she wouldn't realise it was me. I pull my hand out and I'm just complete red and slightly sweating just thinking, oh jesus, that was ridiculously  close.

Then you got my girlfriend giving me this weird face, seeing the awkwardness that she knows I made a mistake and was groping the wrong leg and starts to do this silent hysterical laugh.

I just sat there like a stick for the next 40 mins....
<bot>: Watched GoT with girlfriend and her sister, groped sisters upper leg..possibly kinda half raped her by accident?
