Tease her ass

As you carry on fucking her tight pussy you move your hand down and circle your finger around her asshole

"Hm... I'm not sure about that" she says through her moans

"I wish you'd love whatever I want to do to you" you command her

"Although it does feel very good after you say that..." she giggles

You carry on circling her asshole before slowly pushing your digit inside her, she moans out as your finger goes deeper inside her

"Hm... that feels so good... What about we swap that finger for something else?" she says teasingly

What next then...

(Note: Feel free to comment below with what you'd like to see next, I'll do what I feel comfortable typing about and it'll probably take a day or two to type it up otherwise I'll just keep going with whatever pops into my mind at the time)
