Sarah tells the Father "No."

"No, Father," Sarah says meekly as the priest sways his hips back and forth rubbing his cock against the back of her head through his robe. "I can't. I must be strong for my husband."

"That's very admirable, young lady. But I'm afraid we both know the truth about you. You told me you were a 'cum slut' - a 'total cum slut' - if i recall correctly. Now tell me exactly, what is a cum slut, dear?"

After Sarah doesn't respond immediately the priest tweaks her nipples and repeats his question more forcifully.

"A cum slut is a woman... is someone... who likes semen. Who is hungry for cum. And who especially... who likes to drink it." Sarah responds mortified and afraid. She knows just what a cum slut is because she is one.

The priest stops playing with Sarah's tits so that he can lift up his robe and expose his cock. He moves in front of her and sticks his cock in front of her face. He's not even close to being your side, but he's bigger than her husband. His balls, covered in wiry grey hair hang low.

"Do your thing, cum slut," the priest says.
