i (19F) think my sister is attractive and i kissed her and more…

i’m 19 and my sister is 18. i’ve always thought my sister was pretty but it’s gotten to a point where i’m now bi and now i actually like her. like obviously im not making any insane moves but i just think she’s beautiful, but maybe that’s bc we look similar idk

my sister is a virgin and ive always wanted to have a threesome with her. i want to teach her how to have good sex and how to please and be pleased

my dms are open
