The man cums, but where?

As the man increased the pace and force of his thrusts, each thrust drove the breath out of her, her face flushing from shame as she struggled to keep her grip on the sink.

Each thrust battered her little pussy, and drove her up on her toes. The man had complete power over her.

Too focused on her own ordeal, she did not notice that after what felt like an eternity of being pounded from behind by this huge stranger, the man fucking her was close to cumming. He drove into her faster and harder with each stroke until right before he came, twisting her hair painfully tight in his own pleasure and squeezing his other hand tight around her neck without considering her discomfort.

Krissy struggled to breathe and feared she might pass out at any moment.
