She's not stopping

Diane continues showing off her experience when she doesn't neglect your balls, shifting down and sucking all around this second pleasure centre, all whilst continuing to jerk your cock with her right hand.

After spending some time slobbering all over your balls just the way you like it, she comes up and starts playfully licking around your tip once again.

"I'm surprised you've lasted this long. Most men would have already shot their first load all over my face by now." She taunts.

"I'm not most men." You taunt back.

Diane lets out a playful giggle. "No, you're not."

Next she climbs down from your desk and kneels at your feet. Here, she uses both her hands to grab a handful of her tits each and start sliding them up and down on your freshly lubricated cock.

She seems to be enjoying this almost as much as you are, smiling and moaning as she bounces her enormous tits up and down on your cock. Eventually, once she's had her fun doing this and is surprised to find you still haven't reached a climax yet, she stands, grabbing your tie and leading you over to the couch in your office.
