21 [MF] ME and my sister just masturbated together…

Hi, I’m a 21 trans female, I was recently castrated. I’ve been using a dildo pretty much 2 days straight now, because I was finally cleared to have sex after my surgery (finally)

So I have to share a room with my 18 year old biological sister, because I had to move back in during quarantine. Earlier this morning, she burst in without knocking and I was riding my dildo on my bed. So I start freaking out trying to cover myself up and I’m screaming at her and she just smiles and pulls out this two foot long double ended dildo from under our bunk bed.

At this point I’m just quiet and she is climbing up the side of the bed sucking on one end of the dildo. She gets up to the top and pulls her panties off under her sundress,

I really dont want to get into the porno of it but we were ass to ass for at least half an hour and it felt so good but now I feel filthy. IDK what to do.
