She likes it

I can feel Lunas tongue teasing my asshole as her hand gives me a nice massage. I moan deeply as she lets her tongue swirl around. I knew I would love it and don't hold back. Three minutes later I shoot my load onto the floor as her hand and rimjob continues until I move away.

That's what I needed.

I will not lick your cum from the floor. I laugh. Nah, I wouldn't ask for that, but I have two demands for you brat. If you follow the first, you will twitch in my bed tonight and enjoy all what my tongue and fingers can offer.
If you fulfill the second one... I owe you one and you can name almost anything that comes to your mind.

The first demand is easy. Back downstairs I watch Luna kiss Ben on his cheek with the same lips that just sucked me off and then teased my asshole. As we drive back to my place I ask her for a favor and tell her what she needs to do in order to fulfill the second demand.
