His crotch

Some of the cum on Sarah's cock lingered. She rubbed it on Tom's cock.

It slowly shrank down to a baby dick.

Tom grabbed it trying to make it stop shriveling away.

His cock was an inch long and as wide as a pencil.

The effect on Tom's personality was immediate. His confidence vanished. He seemed to shrink. His stature slumped. His posture took on a bowing position. He was meek and mild. A shadow of his former self. So much if his identity was connected to his cock that he lost most of himself.

"What did you do to me?" he whined. No ounce of strong timber remained. His voice itself was higher and softer. He looked like he was going to cry.

Sarah felt very superior to him. Her image of him was tied to the size of his dick too.

She looked down at her wimp of a husband.
