Yes. My older sister was the first one to catch us. She obviously wasn't happy, but once she understood how we felt about each other, and that it was two adults making a conscious decision rather than just a fling, she eventually came around. Especially given she and I used to mess around growing up, so she couldn't very well be a hypocrite. My entire family - us three sisters and mom know and are all totally supportive. Older sister and bil are super excited to be a grandparents, and mom similarly to be a great grandma.
