Neither

Kim blissfully wails as James continues to churn her pussy up, one powerful, deep thrust at a time.

The poor, nerdy girl is practically senseless now as the pleasure washes over her.

She babbles and coos and loudly moans as her arms and legs instinctively wrap around James to keep him close.

He's so close now. He can feel his balls tightening up. He looks into Kim's eyes as he hits her one last time.

She cries out in wordless ecstasy and throws her head back and closes her eyes as the pleasure crescendos within her while James grunts and thrusts, but then...

Silence.

A sudden emptiness overtakes Kim as the weight is lifted from her body.

"Why did you stop?!" Kim whines, her orgasm completely ruined.

She opens her eyes and sees... nothing?

He... he's gone! Kim slowly props herself on her elbows to see where James might have gotten off to.

Instead, all she sees is her supervisor, standing in the doorway, a frumpy, dowdy, middle-aged woman who appears none to pleased.

"Would you care to explain yourself, Miss Perkins?"

Kim blinks in confusion and then nervously covers her naked, sweaty, and increasingly embarrassed self.
