Finishing (for now) on the bed.

Tia rides you while holding your hands.

It is both romantic and a way to control you.

"Make me cum and you get to see these tits."
She lets go of your hands and speeds up.

Challenge accepted.

You make her cum a minute later and she pulls her tits out of the cops.
She leans in just out of reach for a moment.

"We've got a week," she says, "Let's make this last."

She gets up and you think she's done...but she soon sits back down on your dick facing away from you.
Her tits are covered yet again.

She turns around fully and starts to ride you yet again.
You don't go reach for her tits- it would be a stretch anyhow- but do grab her firm hips.

She slows down a minute later and looks back, grabbing both cheeks.

"I'm a naughty MILF. You should spank me."

You are happy to oblige when she moves her hands away.

She moans in lust as the smacking begins.

"I'm a dirty MILF that is offering her ass to you later- if you can earn it."
You spank her again and she moans.

The combination drives her over the edge.
She cums hard, crying out in joy.

She knows that you're nearly done- especially with the promises and dirty talk- and gets up.

She exposes her tits for you, but tells you not to touch them yet.

Laying on her back, she lets you fuck her hard and fast.
You soon pull out and cum just outside of her pussy and on her abs.

"Good stud- knows not to cum inside without asking.
Next time- count on it."

You smile and recover on the bed.

Eventually, you leave to let her clean up- you note that the Shower is next to your room- and you clean up a bit as a cover story before your Mom returns.
Can this week get any better?
