Try and set her tits free

You reach your hand in from the top of her blouse and slide it inside her bra, your fingers reaching down over the bulbous curve of her breast quickly finding the hard nub of her nipple.

She gasps as your fingers flick over it the first time. You're glad to find it already hard, reassuring yourself she isn't a complete sexual ice queen - or is it just still hard from the window breeze?

Anyway, you reach past her nipple deep inside her bra fully cupping her rounded breast. You thumb comes up and works away flicking over her nipple and around her areola. She can't help herself but let out a soft whimper.

You continue massaging her breast and flicking at her nipple - but really you want to get a good look at her tits. They're impossibly round and firm so you're **** to get one final look at them before the week begins.

You try levering her left breast out of the bra. Her bra is tight around her chest but you begin to push it upwards out of the top. As it begins to bulge out you feel her upper arm pushing against your hand preventing it from getting any more leverage.

Even just one glimpse of her nipple would be enough, so despite her remonstrating arm, you lever down with your wrist pulling her blouse and bra away from her chest enough to get a glimpse of nipple. Her smooth pink areola is flat accentuating the erectness of the nub of her nipple. You rub over it, folding it under your thumb, it springs back to immediately. You desperately want to pull her tits fully free and lick her nipples.

Again she starts to wriggle trying to take your hand out of her top. "Someone might see!"

"Okay, okay. I'm sorry. It's just you make me so horny."

She smiles shyly as her hands keeps pumping away at your shaft. "Are you going to finish soon, I don't want to be late."
