She grants him ten seconds...

You notice you are holding your breath as you wait for Miranda to reply.
She seems to be a little hesitant to refuse, probably aware that she could easily solve her situation with that, given Tom's level of arousal.

"Ok. But just ten seconds,Tom ... I really mean it."

"S-Sure, don't stop stroking now..." Blurts him in reply, eagerly hurring himself to cup both her breast with his hands.

"And please, try to be gentle for once..." She sighs noticing that the douche's hands already begin to maul her flesh.

You understand that there would be no point for her to be shy now, yet you die a little inside as you watch that she ramps up the pace of her strokes.
She is doing it to just to speed up things, that's obvious, and Tom also approves.
You can see that her hand is pulling out of his mouth stifled grunts and wheezes of appreciation.

"Lovely...the look so delicious..." You hear him gargle before diving his head down on Miranda right breast.

"H-Hey! Not like that, stop!" She squeals feeling him starting to suck on her nipple like a baby, "Stop that... You can't be seriously doing that, Tom ..." she hisses tring to wriggle out of Tom's grasp.

"Stop it or I'll scream!" You hear her gasp the moment he squeezes her left tit into his mouth like a juice bag.

To you, it's clear how the douche is mostly unaffected by her words...
Also, despite what she has just said, you notice that Miranda too isn't anymore trying to back away form him and neither she seems about to stop stroking is cock anytime soon.
The asshole's tongue, albeit rough, appears to be having some kind of effect on her at last.
Her face is of a bright red, and she appears to be struggling to withstand his **** without moaning.
The sitatuation develops quickly anyway...

While he still nibbling and fondling Miranda's breasts, Tom lets out a deep stifled grunt.
The spurt is strong and sudden, it splatters all over your crush's bare midriff, who gasp suprised as she only too late realizes what's happenig.
Yet you watch her still herself, bear Tom's eager mouth and hands a little longer with her eyes to the ceiling, while she proceedes to milk cock dry with what you would describe as commendable stoicism, through quick, relentless strokes.

A moment later they have stopped.
You watch them remain like that, frozen, for a few seconds before Tom draws back his face from her clevage heaving a flustered.

"Go out. Now." Says Miranda dryly pushing him further away and turning your in your direction.

As she does, you notice the thick white splotch smudging her toned belly, just under the slight sag of her right breast.
