Wife's Slut Text

I literally just got a text from my wife about possible anal tonight.

Her text

Hey babe how's work today. So im just giving you a heads up that I might be all over you tonight once the kids go to bed. I had the hottest dream of you lastnight.

Me: oh yeah? do tell

Her: like I know we have never done this before but... my dream was that I was riding you reverse cowgirl with your dick in my ass and i was fucking loving it.

Me: wow holy shit, Im definitely down to try that.

Her: oh yeah, like when I woke up this morning I definitely jizzed in my panties through the night.

Me: I'm a little shocked but if you wanna try it I think it would be fun as hell

Her: so yeah I wanted to just give you the heads up that I think i want your cock in my ass tonight. Hope the rest of your day is good

Me: (smiley face emoji) and super hard right now.

Her: (kiss emoji)

So like do I prepare or just go with the flow when I get home?????

My mind is kinda blown.
