Millie takes it in the ass

I slide my dick slowly out of Millie's ass, then gently push it back in, then continue rhytmically pushing in and out of her ass. I feel Millie starting to relax more, so I ease my dick almost all the way out of her ass, and then with one hard thrust shove it back up her ass all the way to the hilt.

Millie screams out loud from the surprise of this change in pace, but I don't take any notice of this, instead I slide my dick almost all the way out again, then slam it back in again.

Millie again screams out, but this time in delight, and she arches her back more to make it easier to push deeper into her ass. She then looks over her shoulder at me, saying:

"That's it Matt, fuck my ass hard!"

I push my dick deep into her ass, then say:

"Yeah, you like that?!"

"Fuck yes!" Millie shouts, and reaches behind her with both her hands pulling her ass cheeks apart, screaming:

"Sodomise me Matt! Sodomise my little butt hole!"

I start fucking Millie's ass harder and harder, and she is moving around wildly in front of me, raising her butt up to receive my thrusts.

I normally would have cum by now, but since it is not long since I came my stamina is surprising, so eventually I slow down my thrusting into Millie's ass, fucking her at a slower pace as I catch my breath.

After a few seconds of this, Millie looks over her shoulder at me, saying:

"Do you want to switch position?"
