My sister (F21) and I (F18) both went on vacation this weekend with our family, it was only a couple hours from us so we just drove because we figured it’d be cheaper. My step dad was driving and mom was in the passenger while we were in the back together. Growing up we’d go on a lot of roadtrips so we’ve got a system to make the most out of the little room we have.. it’s kinda weird thinking about it now but to make the most room when we sleep, we will basically sit in a position where my legs on top of one of hers and the other is under her other leg (basically the position for scissoring).. but it just makes the most out of the bench we have to sit on so after we got in that position to get comfier, she rested her hand on my thigh. Which normally wouldn’t be weird except she started squeezing it and reaching up higher and higher, eventually almost touching my pussy but never actually touching it. It was getting me so wet but I don’t know if I’m into incest or it’s just my bodies reaction to human touch.. please help me.
