Accidental Message, Interesting Response

So this isn't to advertise, it's just to set up what happened and why. Me and a few friends of mine (I'm a guy, they are women), give explicit vids pics in return for Amazon cards to people. I THOUGHT I was sending a pic to one of those people, but it turns out it was my female cousin.
She did a laugh emoji reaction and I quickly deleted it.
Then she put a sad face and said I didn't have to delete it.
I wasn't sure how I felt about that. Kind of an embarrassing excitement.
I responded by saying I'll put it back if she sends one.
She responded with a pic of her tits...and I must say....they were great.
I was getting hard and was ashamed of it.
I complemented her and wasn't sure what to do from there.
She started talking about how it had been months said she'd been laid, and I said it had been the same for me.
She started sending pics of her sex toys, and I did the same.
I had this open ended vibrating stroker that she had never seen anything like before. She asked me if I would show her how it works.
So I did, I sent a video of me using it.
She responded with a video of her using a dildo.
I couldn't help it...I watched it on loop until I came. I shot out through the open end of the stroker all over my stomach and chest. I sent her a pic of it.
She responded with a video of her sucking her clean after she came.
Afterwards I explained what my pic was originally for and funny enough, now she's part of the group that provides pics and vids.
We've also half jokingly talked about experimenting...just hands. But so far it's just talk. But we do still send each other things now and again.
