About me and my sis

Okay so me and my sister tell each other everything but there was a couple of times that we wouldn't tell each other something. We would tell our little sister she's great to talk too as well. Anyway we were all together talking about the stuff we usually talk about then sex came in to the topic and me and my older sister ( witch is crazy cause we are the same age for a month) both looked at our younger sister (15) and both smile me and my oldest sister both had something to say about having sex for the first time and not telling each other we were both to scared to tell eachother that we had sex 😂 but we good now we talk about sex when see see eachother lol
