The pastor's wife and her sister-in-law, both evangelica sluts, can't resist the urge to fuck their husbands' friends. They're always horny, always ready to take a big black cock in their tight pussies. The wives, dressed in their best Sunday dresses, invite the men over for a "study group," but the only thing they study is each other's bodies. The husbands, oblivious to their wives' infidelity, leave the room, allowing the evangelica sluts to strip naked and begin sucking and fucking the black cocks, their CCB (Comedor de Cueca Branca) fantasies finally coming true.
