Preparing Patti's ass

"You ok with being fucked in the ass in that position, or would you rather be on your back?" Millie asks Patti as she enters the room.

Patti looks over her shoulder at Millie and says:

"I prefer it this way."

"So do I." Millie replies as she is walking over to the sofa. Millie stops behind Patti, and for a while just looks at Patti's ass, admiring it.

"Wow, for a 47 year old she does have a very nice and firm ass." Millie says and looks at me.

I stand up and move next to Millie, looking at Patti's ass. I put my hand on one of Patti's ass cheeks, look at her ass, nod, and say: "Yes, she does have a really nice ass."

Millie starts rubbing Patti's other ass cheek, looks at Patti's ass, then looks at me and smiles. I lean down and kiss her, so we are standing there kissing each other, both of us with a hand on one of Patti's ass cheeks.

Millie breaks away from the kiss, we both look at Patti, who has turned her head and is looking at us over her shoulder.

"Sorry, we are ignoring you, are we not?" Millie says to Patti. She opens the tub of anal lube and smears a large amount on the opening of Patti's ass. I reach down and spread Patti's ass cheeks, so her tight little light brown ass hole is easily visible to Millie and I.

Millie dips her finger in the tub of lube and then slowly slides her finger into Patti's ass. Patti flinches a little from feeling the cold lube inside her ass, but stays in position.

"Wow, you got a tight ass." Millie says to Patti.

Patti does not say anything.

Millie looks at me and says:

"You will enjoy this, she is very tight."

I nod and look down at Millie's finger slowly sliding in and out of Patti's ass. Millie slips her finger out and says:

"Feel for yourself."

I put my finger in the lube and then gently push it into Patti's ass.

"Wow, that is a tight ass." I say to Millie, and Millie starts kissing me. We kiss for a while, my finger going in and out of Patti's ass, then Millie breaks away from the kiss and says:

"You need to be rock hard to get in there."

With that, Millie gets on her knees and starts sucking my dick which by now feels fully hard. I look down at Millie sucking my dick, then look at my finger in Patti's ass, and start fingering Patti's ass faster.

Millie looks up at me with my dick in her mouth, a glimmer of excitement in her eyes. She sucks on me a bit longer, then takes my dick out of her mouth, stands up and says:

"Ok, I think you are definitely hard enough now."

Millie moves to stand on Patti's side, reaches down and grabs Patti's ass cheeks, one with each hand, then she spreads them apart exposing Patti's ass hole, saying:

"Now fuck my big sister in the ass!"
