In a forbidden tryst, two nuns, driven by carnal curiosity, attempt to pleasure each other in their convent's secret chamber. They start by kissing and fondling, their habits rustling as they eagerly explore each other's bodies. One nun, Nand, becomes bold and pushes her partner against the wall, her eyes gleaming with lust. She slides her hand between her sister's legs, feeling the dampness through her undergarments. As they grow more passionate, Nand attempts to penetrate her partner's tight, untouched asshole with her fingers, but the inexperienced nun winces in pain, causing Nand to withdraw abruptly and realize their mistake.
