Met few cool girls online

So I'm a lesbian and it's hard to find people like me to hook up with so i try many dating apps but all are headache so one day my male friend approached me and told me about a online group first I was hesitant still due to curiosity joined it and in that group found many ppl talking to each other and ignoring the boys i started talking with this particular girl and i was having my ovulation at that time aswell so we started flirting and talking naughty stuff and our vibe matched so we started to talk on a regular basis and we decided to meet and have some fun together so everything was good I was also excited to meet and i really wanted to try stuff with her but everything changed when I saw her face after meeting it was my cousin sister.
