I fuck Millie in the ass

Millie finishes lubing her ass up, and hands me the tube of KY.

"Lube your dick up." Millie tells me, then climbs up on the bed in the doggy style position. I shift around so I am kneeling behind her, and her ass looks so inviting.

I reach for her ass, and squeeze her ass cheeks a bit, spread them apart, and look at Millie's asshole. It looks so inviting, it is light brown in colour, and covered in lube.

I slide a finger into Millie's ass, but she flinches a bit so my finger pops out. I push my finger back into Millie's ass, and Millie says:

"Sorry for flinching, am just a bit nervous."

"Just relax, don't be nervous." I reply.

"Easy for you to say, you're not the one who is about to be fucked in the ass." Millie replies.

It really turns me on to hear Millie talking about being fucked in the ass, so I say:

"Ok, I am going to fuck you in the ass now Millie."

"Be gentle." Millie replies.

I start pushing my dick against Millie's sphincter, and it quickly opens up and my dick slides into Millie's ass. She does not react very much, so I push my dick in all the way to the hilt. The ease with which I am able to do this shows that Millie is very accustomed to being fucked in the ass.

I slide my dick in and out of Millie's ass, and her sphincter quickly dilates, she is now very relaxed, and starting to enjoy herself.

"What is happening to you right now?" I ask Millie.

"I am being fucked in the ass." Millie replies.

"You like that, Matt, you like fucking me in the ass?" Millie says.

I am too busy enjoying her ass, so I just groan in reply.

"Yes? You like sticking your dick in this big titted MILF, ass?" Millie says.

I groan in reply, and Millie starts moving her ass back and forth, and she meets my thrusts into her ass. She is enjoying this.

"Yes! Yes! Fuck me in the ass! Yes! Yes!" Millie screams.

I look down and see my dick sliding in and out of Millie's ass, and I feel myself starting to cum, and I empty my balls in her ass.
