Loan's tongue trails down Thao's quivering stomach, her breath hot on her sister's slick core. Thao gasps, her fingers digging into Loan's habit as waves of pleasure crash over her. They climax together, their cries of release echoing through the silent convent, a testament to their unspoken, unholy bond.
