I have seen Krystal twice, the only times I have been to SRM. I certainly don't feel the need to see anyone else from there yet.
I'm tall, so I like the fact that she is tall. She's very slender, but that's perfect because both times we've spent about half the session together on the shower. That part is my favourite.
And talk about a friendly girl. A super friendly greeting, holding your hand walking to the room, a nice hug and squeeze once you get inside and a super open minded attitude make her someone who I really enjoy spending time with. Reminds me of a girlfriend from way back.
I didn't really notice any foul mouth characteristics, but then I didn't initiate any so she probably takes her cue from that. But she is open minded, so I could see her getting into that if that's your thing.
I'll be asking for her the next time I visit there too.
