>Day Gravity Well in Equestria.
>It's been a few months since you've arrived in Pastel Pone land.

>You go to knock on the doors but they open inward on their own.
>”Hey there sailor, come to this port often?”
>There she was.
>Luna was splayed out seductively on her bed, ready and waiting for you.
>Damn, that's attractive.
>Wait a sec, that gives you an idea!
>You begin pantomiming like you were resisting being dragged towards Luna.
“Whoa! What is this...irresistible force! I can't fight it! It's like I'm being dragged towards something!”
>Luna is looking fairly confused now.
>”Anon, what are you doing?”

>No one got any sleep in the castle because of the two of you.
>The following morning, Celestia booted you out of the castle because she couldn't sleep at all.
>You think she was just jealous she didn't get any dick.
