TIFU by having a contact saved as daddy

I 20m was playing cards with my family when my dad 45m and my sister 25f were joking around with my phone.
recently my brother 17m and his two friends snooped on my tablet. I left on playing a game and found out I liked dudes.
btw I’m bisexual
so my sister joked around with my dad and said to my dad hey tell Siri to call daddy.
I tried to stop them since one of my best friends I have them saved as that,
they ended up calling and it popped up I tried to lie and say I don’t have anyone saved under that.
I knew they didn’t believe me and I now I’m laying in my bed writing this so Reddit today I fucked up by saving my friend as daddy
TL;DR : I saved my friend as daddy my sister and dad took my phone and jokingly said to Siri call daddy and it did
